Why GM doesn't stand behind their product?

That's my question and with all the BS from dealers ,that I have read about here, I think it's time for a class action to be taken. Parson's Chevrolet told me that the solenoid valve was not covered even though I explained that it malfunctioned well before 36K which is the bumper to bumper warrranty. I then asked why the EVAP is not covered for 80K and the reply was that it is except for that part. This is the same dealer that when I went to buy-out my lease they told me "we don't do that anymore" more BS and a talk with their finance person changed their story. The salesman was trying to pull a "fast one" and again the consumer was the victim. I hope some starving mouthpiece out there reads this and takes action against GM on behalf of all of us who have been ripped off!

Apparently by federal law only the major parts of the emission system are covered for 8 years/80K miles. The major parts are the cadalitic converters and computers. The other parts only have to be warrantied for 2 years/24K miles. If you have a bumper to bumper warranty everything should be covered. Check for exceptions in your b2b warranty.

GM, along with the dealer, has lost a failthful customer. I was lied to by the salesman when I purchased this vehicle and the fact that the warranty is not honored is enough BS for me.

Does anyone know the specific part # that I should be looking at in order to replace the Evap Emissions Control? My OBDII scanner read P0449. I assumed it was a loose gas cap, which it could very well be, since I filled it up a few days ago. Cleared the light and went on my way and it hasn't been coming on since, but I'd rather just replace it now and save myself the headache later on down the road.

I have an 08 Tahoe LTZ. I want to replace the entire purge solenoid, as well as the evap canister.

I've seen 12597567, 19207763, 2593-2571. I don't want to order the wrong part and have it be for a Malibu when I have a Tahoe.

Thank you guys in advance.

Tungo- Watch 2007 Suburban P0449 - YouTube this video. I had the same codes 0455 and 499. I bought a new gas cap and replaced the EVAP purge valve in this video and the connector/adapter. Fixed my problem easily. Also check out the 0449 code problem on the tahoe and burban forum. Good luck

Here ya go
GM # 20995472 - EVAP canister vent/valve/hoses/filter assembly= $71.96
GM # 19257603 - Electricaladapter/harness = $30.14
You need the adapter because the new and old electrical connections are different. It's about 6 inches long
Good Luck

Evap

I was ripped by the dealer and ended up fixing it myself while still under warranty. I'm done with GM. The solenoid valve is next to the spare tire on an 07 Tahoe and the large line running to the canister will pop off if not clipped securely in place. A real piece of crap. I have yet to meet a person that is not getting the loose gas cap code----------------- Isn't time that GM starts to use engineering and stop the politics just like our gov. needs to do. This country's politicians and the auto industry is screwing the public . IMO
