Ok so if i was to do a CAI, IC piping and DP would they be able to tell? Being i would put it all back to stock if i ever needed to take it in the shop.

 

def not the cai, i just got one installed by chevy. im not sure about the ic piping and downpipe. i know exhaust doesnt void it so prob the dp would be ok

 

use search button please
and your wrong, exhaust after catalytic converter is ok, but changing downpipe tampers with federally mandated oem emissions equipment. Even a downpipe if it is a catted design, they may void your warranty. All DP's are "off road pipes" meaning not street legal.

Any modification not marketed and approved by GM which helps the engine develop additional power and therefore stress on driveline components may lead to voiding of the factory powertrain warranty

Any COMPETANT tech should be able to easily identify all aftermarket parts, whether they care about screwing you over is another story....

Where people run into trouble is when they somehow blow a motor or start burning oil because they dont know how to properly treat and maintain their car. While the dealer may be cool, the regional rep may be an ass and not approve the work.

A mazdaspeed 3 owner got the shaft when he needed a new motor, and Mazda denied him because he didnt have the dealer do all his oil changes. owner claims he purchases his own mobil 1 and changes it himself, mazda says "not good enough" Mazda denies warranty coverage due to "neglect"

you can bet that with GM's perils warranty work is only going to be reimbursed under the most strict protocol, and anyone with non GM performance mods is gonna be picking up the tab on powertrain repairs

 

You serious? Wow thats weak, definitely scratching mazda off my future car purchases.

 

hate to say it, but its gonna be like that for more than just mazda, i mean if GM is hurting as bad as they say they are, then this will be typical

 

iasked my dealer n he sed DP IC PIPING WILL VOID THE WARRANTY..CAI and CAT-BACK will not..thats what he said i dunno it may be different at your dealer.

 

who do you go to to ask these type of questions?

 

LOL, thats nothing.

I recall the fiasco about Subaru giving free SCCA membership to new Impreza owners, then go to different autocross events to file all the vin of those car as a basis of voiding warranty should the circumstance arises. They will visit forums to see who races their cars and use some type of window cleaner that can reveal residue of shoe polish numbers on windows.

As in anything in life, there is no guarantee. If they have to VOID your warranty, there are million ways to do it. This is exactly why I laugh at people who still uses the Magnuson-Moss Warranty Act from the 1970's like a jail free card.....

Go read your warranty, odds are you already voided them.

 

With my GTO, I installed a cam, ported heads, CAI, Magnaflow exhaust, tune, etc. Drove it into the dealer with my drag radials on to have them fix the power door locks. No problem, they fixed the locks and thought the car was cool. Now if I had tried to get them to rebuild the engine due to a burnt piston or something, they would of laughed and said no way. The point is, mods won't automatically void the entire warranty. You need to use common sense. If you are truly worried about the warranty, then don't mod.

 

Will bolt on part most likely will not cause a full powertrain warranty to be voided(most likely just the particular failure) You can BE SURE that if you have a powertrain failure and you get caught with an aftermarket tune GM WILL VOID YOUR ENTIRE POWERTRAIN WARRANTY. Ive seen it happen, GM is really cracking down, and is completely voiding powertrain warranties for aftermaket tunes, period. No second chance, no what if I take it out.....If you go in for warranty work on the powertrain(trans, engine, axles, hubs, etc...) and GM asks the dealership for a calibration check and youre not stock....GM voids the warranty, right then and there, no questions asked....Ill see if Ive got the screen shot from the email they send.

 

I did warranty for an auto supplier and its easy to void a warranty. If they want to void it they can always find something. If all else fails just deny it for no reason than to waste time hoping they cant fight it or will give up after awhile.

 

I dropped my car off at the dealer with my mods listed below to have my leaky transmission fixed and my steering intermediate shaft replaced... dropped the car off at 830am, car was done and ready to be picked up by 11. 100% depends on the dealer.

 

Here ya go.....

 

Is there anyway to set the tune back to stock? i mean if u have an intake or exhaust i dont see how GM can void ure warrenty but the tune i can. Thats why you save a stock profile tune... I have asked this before but no one has commented.

 

If you have hptuners then sure.

 

then how come people would use anything else.. hptuners is good for 650$ and re sellable.. and if used properly will not void warrenty. I feel that this is the best bang overall for the buck.

 

Because GM can see how many times your ECU has been programmed and reflashed to stock tune...doing anything to your ECU that is not done by a dealer will void your warranty...unless the dealer is too dumb to check your ECU when you take it in...

Bottom line...if you want your warranty to stay in tact, do not touch the ECU...

 

Yep , even if flashed back to stock they have the ability to see that it was recently flashed. If HP tuned LNF cars start tossing their cookies..... I hope their owners aren't expecting powertrain warranty work .....

 

Basicly you should buy another PCM!

or wait on the stage kit and mod it?

 

Where would you get another ECU? And they wont be able to tell that the original ECU was taken out, and then put back it?

 

They should be able to tell...I doubt anything will show up saying "ECU #2!" (hahaha)...but they would be very suspicious of some of the inconsistencies in the information...

GM is not stupid and they will not throw money into a car that has not kept their end of the deal on the warranty...unless you have a stupid dealer, just don't mess with it...

 

Wait on the stage kit...

 

The new ECM will not work unless you go to the dealer and have them program the clutch position sensor into it. Your dealer will become kinda suspicious if you have two ECMs.

 

i dont honestly think a tune will hurt these cars though considering the stage kit is coming out!

 

It should not but you know the GM tune will be very conservative in order to keep driveline stress down. ADM performance says it is good for approximately 25-30 whp on their HHR compared to a lot of the custom tunes that can add up to 55 whp on their own.
