Warranty

[jr_garcia152]

So i just removed my mufflers on my car amd just did straight pipes. Now for some reason when i drive, my transmission seems to be slipping sometimes when i get to 35-40mph range. i'm wondering if my warranty is avoided if i take it in to check and possibly replace my transmission.

I am making an assumption that by going to straight pipes you are lowering the back pressure in your exhaust system and thereby altering the factory settings of the emissions control system (and possibly other systems that depend upon one another).

Hyundai, like every other manufacturer I know of, will insist that your vehicle is in stock, factory-delivered, form before they acknowledge any problem with performance - and IMHO this is entirely fair. It is unrealistic to expect a major manufacturer to act as a custom speed shop in troubleshooting a problem which may have been introduced by after market modifications.

Also, it has been my experience that someone who alters their exhaust system to produce more noise tends to drive the car with more gusto. If you have done that you might find you created a transmission problem with more sporting driving. These cars are sedans but are not intended to be driven as would a genuine sports car.

So, my answer to your question is to return the car to its original condition and then, if the problem doesn't go away, take it in.
