Warranty and Modifying delemma

Hyundai says they have a 10 year 100,000 mile warranty on the drivetrain of their cars. Hyundai is also saying the Genesis Coupe will be a Tuner car. So the delemma I see is that Hyundai is advertising the Coupe a certain way, almost implying that modifications will happen or even encouraging it. So will hyundai support their warranty if a person does modify their car? If not, what kinds of modifications will void the warranty? That being said I don't expect them to back up a warranty if I am running 30 pounds of boost.

Your fears are understandable Fastcoupe. However Nikon's link shows there are laws that help protect us the consumers, especially on products where a warranty is provided. In many cases multiple warranties are provided, such as Hyundai's various limited warranties. For example Hyundai has these warranties: Powertrain (10yr/100k), New Vehicle (5yr/60k), Anti-Perforation (7 yr/unlimited mile), Replacement Parts/Accessory (1yr/12k) and Emmision/Performance warranty (8yr/80k).

So what does all this really mean? Well you are free to install or modify your car as you please but if a dealership finds that your modification was the direct cause of a malfunction then they do not have to honor the warranty for that specific claim. However, they can not say your Cold Air Intake was the cause of your anti-lock brake computer breaking, or they can not say your aftermarket exhaust caused your air conditioning to stop working and they can not say in generalities that because you have modified or have aftermarket parts on your car they do not have to honor warranty work.

Another added benefit is that the dealerships can not deny your warranty claims because you did not get service through them or because you didn't buy a Hyundai oil filter.

The flip side is if you swap in a bigger turbo and you are making 500 HP and then go blow your engine up because the fuel pump died, they can now say that your modification was directly (fully or even partially) the cause of this engine failure and you would be SOL, warranty claim denied.

Now I have seen cases where a dealership is very nice and they will help you out even when you have mods that could have been partially the cause of a failure. For instance my brother's SRT-4 is modified (reflashed, exhaust, big intercooler) and makes around 260hp to the wheels. One of his axles broke, could have been a fluke, maybe it was the auto crossing, maybe the drag strip abuse, who knows. Now the dealership could have been jerks about this and said "you are making more power than the stock parts were designed to handle and that is why your axle pre-maturely broke. we're not covering this", but they were cool and replaced it no questions asked. They replaced both sides actually. Basically this shows that some dealerships are nicer than others so ask questions find out which ones are cool.... We'll be setting up a section for dealership reviews and a place to report mod friendly dealerships so everyone can know which ones to avoid and which ones to support. Hopefully by creating such a section it will give a dealership incentive to provide good service as well.

This is the gist...

We've been discussing this on another forum as well. 1st of all I'm not going to be argumentative about this, just stating the facts from the dealers view point & trying to be unbias as possible. Keep in mind that this is only one particular dealership, one particular service dept, & one particular service advisor, so it may vary as you frequent other dealerships. In the end, the people you are dealing with will make he difference.

If you have a particular part that is under warranty & the dealer can not prove that it failed as a direct result from a specific modification that you made or by lack of/improper maintainance that you had preformed elsewhere (other than the dealer), they are required by law to replace that part if it is still under warranty according to their guide lines.

If you have an internal engine part that fails due to the boost being increased & the dealer can prove this is why the part failed, then they have the right to decline that repair. So, to answer your question, yes turning the boost up to 30psi could cause the decline of a repair, esp since Hyundai, in this case, has disclosed that the engine could only take up to 29psi of boost.

Hyundai has promoted these engines as tuner friendly, but that does not mean they intend to warranty it if it is modified. I will say this though, Hyundai is pretty lax with regards to mods done on their vehicle brand compared to most other manufacturers. Minor mods such as CAI's & catback exaust hardly ever cause a decline on a repair. When they do, it is usually due to the customer installing or having installed the airflow meter/sensor in backwards after a CAI installation. Which I can't fathom since there are arrows on the part showing the direction in which the air should be flowing.

Part of the reason Hyundai has such a small turbo installed on the 4 cylinder & the boost turned down is so they can warrant this engine 10yrs/100,000 miles. They also did it so people would have a reason to choose the 6 cylinder over the turbo4. Finally, of course is fuel economy. So if you plan on turning the turbo up, don't count on Hyundai warranting the engine. Although, I'm hoping if we are still using the factory turbo, we install a better flowing I/E, have the turbo turned up, then the vehicle tuned, that this will not void our warranty.

This will be the 1st time that I've had the opportunity to deal with Hyundai's warranty regarding turbos. So, it is new territory for me. I am happy that the factory turbo itself will covered 5yrs/60k miles from my understanding, unlike most manufacturers 3/36 basic (bumper to bumper) warranty.

I've been working as a Hyundai service advisor for the same svc dept for over 10yrs & I can tell you this, I know Hyundai makes good, dependable, quality cars & parts that last a long time as of late & I trust this GenCoupe will be no different. In fact, I think it will be built even better/stronger than anything else thay the have built up to date, due to the fact they know we as consumers are going to be hard on both these engines, transmissions, suspensions, & brakes. They do not want word of mouth going around that they make weak parts after all this time, money, & energy they have spent trying to get their tainted past cleared up. In fact, if you compare the 3.8L V/6 being used in the GenCoupe to all the other variants being used in other Hyundai vehicles (Entourage, Veracruz, Azera, & even Genesis sedan) there is alot of difference. Block thickness & cooling jets on the underside of pistons, just to name a couple.

With that said, one of the 1st things I'm doing after the break in period & my 1st oil change at 3,750mi, is to switch to Mobile1 synthetic oil. Second, I will take my car down to the dump & put it on the scales & have it weighed with a 1/4 tank of gas. Third, I will take the car to be Dyno tested at Buschur or where ever I intend on having my tuning done. Fourth, I will purchase I/E & install parts. Fifth, I will return to Buschur to have the turbo turned up & vehicle retuned. Sixth, I will have vehicle dyno tested again to see my gains. I hope at this point the I'm still under warranty, but I am not counting on it. I will then roll like that for a year or two before doing any other engine mods.

Eventually, I will purchase the rest of my go fast parts , install them, retune, & dyno again at Buschur etc....
Note: When I replace my turbo with a GT35r, I don't expect Hyundai to warranty my engine if this caused it to fail.

With that said, I'm actually a rather easy service advisor to get along with. I win the quarterly award for highest CSI for my region (south east) on a regular basis & for good reason, I take care of my customers, I'm honest, & unbias. My job is to represent the dealership & the customer, so I'm a mediator of sorts. I have 7yrs of college in the environmental field, but continue to do this because of my love of cars & the care for my customers. Most of my customers have told me if I ever dared leave that they would follow me to what ever dealer I went to. If I left the field, they said they would be out of sorts. So, I'm still here doing what I do, even though I'm burnt out. If anyone ever has a question regarding a Hyundai or it's warranty, please just ask. That's what I'm here for & it's better to know prior to rather than aft.

Sorry, so long winded, but I thought this was a topic that needed discussing in depth.:zzz:

Now this is a man with a plan. Well thought out and I could feel the conviction. I agree though. If you are going to mod the engine, in effect you are going to void most of your warranty. That will put stress on every aspect of the car. More speed and power equals more stress and wear. It should not be the dealer/manufacturers responsibility to repair/replace when stresses are put on a car beyond what it is engineered and sold for. I am not saying it is not over engineered by them to help you/us tune/mod them, it is done more with a wink. It can take it (to be proven), but your on your own at that point. I have no problem with that especially at the price point these cars are suppose to sell. Better to mod a 20k dollar car vs. a 35k car like an EVO IMO. I realize the EVO is a track beast with AWD and plenty of electronic wizardry but I am driving my car on the street 99.9% of the time, and find that stuff nice, but unnecessary for me.

deff awsome info! but as you stated it depends on the service department and how far there willing to work with you. I can say for a fact i own a 03 sonata thats got a lil mods done (cai,exhuast, simple mods), my warrenty was denied for a power steering line, how the two co-inside no idea to me, and my boy who drives an 05 evo went to replace his wing becasue the clear coat wore off, they denied his warrenty also beacuse his car was modded so, long island dealers are rough lol
 
#9 ·
There is no link to the engine and a steering line failure. You should have fought that and made them explain how it is related. Also, those mods you did should void NO PART of your warranty. Those are replacement parts that wear. Unless Hyundai is going to give you free parts in order to keep your warranty in tact, you are free to use any aftermarket part on those items (air intake and exhaust). The paint on the wing is insane. Unless it was a repaint on an aftermarket wing, there should have been no problem unless you were outside your 3 year 36k bumper to bumper, and even then it may fall under the anti-corrosion part due to flaking paint.
 
#10 ·
^^^...+1...CAI & catback have no effect on P/S system & should have been covered up to 5yrs/60k, unless line was damaged during installation of after market parts. Should have asked to meet w/DPSM to present case, then would have probably been covered. Only thing possilbly not warranty from above mods might be MAF if installed backwards could cause it to burn out.

As for paint, there is no mod other than having a panel repainted yourself after purchase that would disqualify it for coverage if peeling, 3yrs/36k. The wing is not metal, therefore would not be eligible for anti-perforation.

I called Hyundai's main office and asked about my tib.The lady told me that the car is still under warranty if the parts are for that car.She said you can't get a honda CAI and put it on or ect.Now i heard with the Genesis if you use the aftermarket parts that they want you to use then the warranty is still good.
 
#16 ·
A CAI for a Hyundai or Honda will not vary much from each other as far as form & function. A CAI purchased from Hyundai & installed by a Hyundai svc dept can't be claimed to be incorrect part for car or installed incorrectly. The warranty is good whether you use parts provided at a Hyundai dealership or where ever you get them, as long as they don't cause damage to another part from their installation or operation. Hyundai will not void your warranty for having after market parts installed, it's against the law to do so. But, if a part you install causes failure of another part, then that part is not covered under warranty.

IMO, one more things to consider, this car is built during the economy trouble. I believe that means something (cheaper parts, cutting cost here and there). Hyundai is a business, so income always comes first. Marketing mean sales, they will market the car anyway they want to get sales, again in this kind of economy condition. I would get to know more about the dealer before you make the purchase. Sales department and service department is like dogs and cats.

as for warranty, i would not count too much on warranty if you are modding you car. The dealer will find ways to make money, again in this kind of economy. If it's possible, could any of you please post some maintenance cost numbers? I have a feeling they gonna charge higher for the maintenance of this car.

The cure for all this is the economy and it won't be until at least 3 years from now.

But this is just my opinion.

Peace.
I have to disagree w/your point regarding this car being built in a difficult ecomomic time leading to the use of cheaper parts. One thing I've learned about Hyundai is they are not going to use sub-par parts whlle trying to build their reputation & instill trust into the consumer. The only way they would use "cheaper" parts is if they are of the same build quality as the more expensive parts, but are simply as a lower cost.

I do agree however that Hyundai is in business to make money, as all business' are. But they, like other business' have been doing will find areas that they can cut fat w/o effecting their product or the customer's perception of that product.

I totally agree w/getting to know your dealership sales & svc depts prior to making purchase. You may even find a sales dept better at one dealership & a svc dept better at another. I can't vouch for most dealerships, but can say for myself, that I have been very understanding in these economic troubled times. I have not put as much emphasis on routine svcs.

Don't be afraid to mod your car but, remember when ever you do that the question will pop up if it pertains to the concern.

This is one of those never ending stories

Some dealer, if your clock changed from digital to analog for the look, they say no warranty unless replace to stock

This was owning Grandeur XG

Which ever malfunction, dealer will say that thing :gay: is the cause :dunno:

If service and part section are selling intake and exhaust from dealer....likely not from Hyundai, those dealers are ok

Then, maybe dealer will ask you, if you install everything here? Paying $80 / hr labor :read:
 
#18 ·
people shouldn't be afraid to mod their cars a little because of the warranty. a turbo back exhaust will never ever ever hurt your engine. an fmic upgrade should never ever ever hurt your engine. an intake should never ever ever hurt your engine.

however, throwing a boost controller on there and maxing out the stock turbo WILL hurt your engine.

it alllllllllllllll depends on what you do.
 
#19 · (Edited)
+1....

& I'll add, that sometimes things that shouldn't hurt your engine, can if installed improperly. For instance, regarding the intake, if a CAI is installed on a car w/a MAF & the MAF is reassembled backwards, so that airflow is going in the wrong direction, it will damage tha MAF. Not huge deal, but those things are kinda expensive. So, just pay attention how it comes apart & make sure you put back together the exact same way.

When I get customers who call to inquire about upgrades on their "new" cars and the first thing they ask is "Is this going to void my warranty?" I always answer with these 2 statements. I do not work for the dealer so I do not know.It is up to the dealer of what will void the warranty. If you're concerned about the warranty I would not modify the car.

The main thing to remember is the dealership/company is supposed to be able to prove that what you did to the car caused the issue (whatever it may be). Now we know if your HID ballast burns up that putting an exhaust on the car isnt going to have anything to do with that BUT... its up to the dealer.

In all reality you buy a performance based car to make it better and drive it how it was intended to be driven. If you want a modified performance based car with a warranty.... its simply not really going to happen.

I am buying this car being fully aware that it is the first BRAND NEW vehicle that I have ever bought and it will have about 150 miles on it by time the warranty is voided. I know some of you will think "Well you work at a shop its different." Its really not. I will have a brand new car wit ha $470/mth payment and if I put a rod through the block I still have to buy a new block. If I burn up the ECU I have to buy a new ECU. Im not rich or anywhere near it but im a car enthusiast who wants to make the car more fun and fast.

Its like anything.... if you want to play you're going to have to pay.

Was in the dealership today to pick up an oil filter. While I was there I decided to ask the service advisor how much it would cost to install new springs. After the 20 questions including... "why would you want to do that", Be careful not to void the warranty" He quoted me a price of $500.00.:yikes:

Now that Hyundai has produced a performance car, I hope they start some kind of training or educate their service department on the following this car is producing.

Not to crush your dreams or anything, but I really wouldn't keep my hopes up. A lot of manufactures make performance oriented vehicles, and they don't condone the use of aftermarket parts.

Each dealership will treat you differently though. Some are cool with any mods, others are anal about as little as a drop in air filter.
 
#25 ·
The thing to keep in mind here is that yes, J-Rod is right, if you really want to make sure you have no warranty problems, leave the car stock. Having a modified SRT-4, I know all about the world of trying to get warranty service with a modified car. The fact is, any dealer can refuse warranty service for any reason, EVEN IF YOUR CAR IS STOCK. Mitsubishi dealers especially are notorious for googling through auto-x results, and blacklisting their owners for denial of any future warranty claims. If you bring your car to the dealer with an aftermarket intake and bov, and the muffler fell off on the highway, they don't have to honor that.

Now yes, we have the Magnuson-Moss warranty act to help us out, that's a huge benefit. But like anything else, you can't physically make them follow it, they're free to deny your claim for any reason, its up to you to convince them to honor it. Most dealerships will work with you if you simply ask how your installed part voids the warranty. Or if the failure or defect is related to suspension, braking, or safety equipment, they will almost always fix it, since they don't want to deal with a major lawsuit should you become injured or killed in a wreck thanks to a mechanical failure on their car that they failed to fix. Yet they can deny powertrain claims all they want, even if you bring up the ol' M-M. You can print it out and try to explain to the service manager, and often he'll have no choice. But if they still won't honor your claim, you don't have much choice other than to either go somewhere else, or get a lawyer involved.

This is simply the reality of things, the dealer knows they can just flat deny you if they want, and the costs of you getting a lawyer involved are almost always gonna cost more than the repair work. They know this, and will often take advantage of that fact. Granted, that can hurt their reputation among other enthusiast owners of your same car, but unfortunately, they know it will have little if any affect on their overall sales.

In summary, the Magnuson-Moss Act does protect us to a degree, but by no means does it guarantee that you will be able to get your car fixed for free after you have done any mods or competition at all. It means that you have something to use in court to make them honor your claim, but rarely is it gonna be worth going to court over. So, if I were you, I'd get to know the service manager, and talk to him a bit and see how they're gonna be. Mention the act if you want, but try to get some statement or at least the general feeling that you will be treated fairly regarding possible warranty claims before you do anything to the car. If not, tell them this is unacceptable and you will be seeing another dealer for all your scheduled service, and even the initial sale if you haven't bought the car yet. But find out before, don't find yourself having to fight the dealer in court for something that won't be worth it.

Oh, and remember, stealership or not, they're still not your pit crew.

This is well said. However, that does not make for good customer service. If the dealer truly feels that your mods have led to failure, they have legitimate grounds. There are plenty of people who hack around on their cars, misuse and abuse them, and then expect to have the warranty cover them when something breaks. Most people who drive normally will never have a powertrain issue. Unfortunately, companies like MITSU, make products that cater to the young speed freaks that mod and tweak, they really don't care if you don't buy again because nothing else in their product line is going to appeal to those EVO buyers anyway when they move on after being dissatisfied. Most older buyers would not settle for the comfort losses that come with that type of car, so most go through that stage in life and move on to more docile machines anyway.

Just ask the BIG 3 what years of dealership failure, mistreatment and lack of warranty has left them when it comes to customer service. They then wonder why they have no customer base left. Maybe it is my age or my gray hair, but when I go to a dealer, I never get harrassed or questioned. If you are 20ish and you own an EVO or SUBIE or whatever and you come in with transmission problems, that probably does send up a red flag if they never see transmission problems from a 40 year old driver. If all trannies that come in with problems are with younger buyers and owners, it probably means something.

That does not make it right, but you have to be real. If you are young and hot rodding and racing and beating on your car daily (just look at you tube for more than enough examples) then you may have problems. I feel that if I purchase an EVO X and go in with my two kid seats in the back, I am a professional, and I just dropped 30-40k I expect a certain level of service and I doubt they think I am hammering the car on the track. The same if I go with the COUPE. If I show up and know that I have not abused the car and they say sorry, there is going to be a problem. If I do know I hammer it and I get denied, then I can deal with that also. I know I screwed it up and was just trying to sneak one by.

You should not buy any car that you cannot afford to make the repairs on, regardless of what they are. IE I don't buy German luxury cars because I do not want to be paying the price for those parts. I stick with mainstream, simple machines.

Good points, & yeah dboz, repairing my car can get expensive quick.

I'm 39 & beat on my cars pretty hard considering my age. But, I accept any mechanical failure that arrises & don't get very upset, because I know more than likely my driving habits probably caused the failure. I also know enough about cars & mods to know when something broke due to something I did or something that should be warranty. Therefore, I will not get upset if Hyundai doesn't cover something I know is my fault. If it's not my fault or my mod that caused the failure & they decline, I will ask to meet with the DPSM.

By the way, the best way to get stuff covered is to get in good with the svc mgr. Upon inquiry about the vehicle (test drive etc.), go back & meet them being inquisitive & cordial.. Meet with them again upon purchase getting a few more details, showing you respect their knowledge & maybe p/u an accessory (i.e ipod cable), just to show you want to do business with them. Bribary works too.

Well, I'd say this was well written, but I don't agree with one part of the content.

No Dealership has the 'right' to deny any warranty claim for any reason unless they can prove an aftermarket part was the root cause of the issue. Many dealers will attempt to do this, but they do not have that right.

I've dealt with my fair share of issues. Last year my car had problems with the Supercharger, and I was denied warranty because I had a Stage 2 kit installed in the car. It took me 5 months of fighting with the dealership and their district service manager, but in the end I got it fixed.

It just depends on how educated you are with the 'rules'. The dealers will always try to rip you off if it saves them money.
 
#29 ·
I agree that dealerships do not have the right to decline claims that are not directly related to a mod or the installation of that mod. Although, I don't think any of the above comments said that they had the right, just that they would try to avoid coverage. But, like you said, they will try to decline most repairs most of the time if your car has been modified, because they don't want to be responsible to Hyundai if a claim is declined & then they are charged back for that repair. You're also right in that it is up to you (the customer) to insist on meeting with the DPSM in order to try to get the claim covered. If the DPSM declines (which does not happen often), it will get a little more difficult & may not be worth the time or trouble for most to proceed.
