I had to have my GMC Canyon (diesel)repaired in Denver at - Rich
I had to have my GMC Canyon (diesel)repaired in Denver at Foundation Chevrolet, where they said that my oil was 1.5 quarts overfilled and that the result was damage to the NOX sensors. I notified Morehart Murphy GMC service of this, since they had done the last oil change, and they responded saying that the engine oil had been topped off or diesel was leaking into the engine causing an increase in oil volume. I know that the oil was never topped off and I decided to see if my oil volume increased after Foundation Chevrolet changed the oil several months ago. Go figure, their xx excuse was false as the oil level has remained constant. The Morehart Murphy service said that they weren't able to overfill oil in an oil change and the dipstick was checked after an oil change. Well I strongly disagree and see that they would never admit their probable culpability. On top of that the Morehart Murphy Regional Group provides no way to file a complaint beyond the shop that has no incentive to respond to problems. I have to question the overall quality of service, responsiveness to problems and ethics of at minimum the GMC service segment.
