2015 GMCTerrain Denali For Sale

GM needs to issue a recall for this vehicle and all the others listed in GM service bulletin #14882. The bulletin describes what needs to happen when repairing a failed rear main seal. The PCV system gets clogged and freezes, causing the rear main seal to fail. There's a picture, in that bulletin, of a 1/16 inch drill bit being used to clear the clog out of the PCV system. That size hole isn't efficient to release the pressure caused by a running engine. The pressure has to be released somewhere, and that's when the rear main seal fails. I was told by GM customer service that only certain VIN's are covered by that bulletin. The bulletin covers those certain vehicles for 10 years, or 120,00 miles. GM expects it customers to cover the repair cost of this poorly designed engine. I didn't design this engine, why should I have to pay for their mistake? This is a manufacturers defect, it should be covered regardless of age or miles. Do yourself a favor and Google GM service bulletin #14882 and ACDelco Canada rear main seal 2013 GMC Terrain, and see the evidence for yourself.

Not much more I can say but the engine stalling is a very common problem and they will tell you fix the cam shaft, to you need an engine flush and valves flushed and then the ultimate end is a new engine and you still may have the issue later. Still no fix GMC. this is ridiculous

Burns oil like oil rig after an explosion. Had the oil consumption test completed at local dealership and after it was all said and done over the specified time frame of testing, was told it is within the limits allowed by the manufacturer for its oil consumption. The AC had to be replaced last year. Then as of this weekend, the check engine light came on and the code was for rapid misfire Idle was awful, display showed service stability traction and Engine Power is Reduced. It wouldnt run over 20 mph and nothing over 8 mph going uphill. Also believe the catalytic converter needs to be replaced. With everything we have dealt with since having this vehicle, knowing what I know now, I would have purchased a different vehicle. Never again once I can get rid of it. Thankfully my husband husband was a mechanic for many years prior to his career change and has been able to fix everything that has been wrong and Ive been able to save money in repairs due to that, but thats beside the point. Do not buy this vehicle if you can help it.
