We took in an Avalanche very near the end of its 36,000 mile factory warranty for repair with this dealer because of loud grinding noises coming from the drive train when the four wheel drive was engaged. The first time in their mechanics told us that they could not get it to reproduce any drive train noise when they test drove it – yet they kept our vehicle all day until close. When we got the vehicle back the drive train noise was even louder. The second time we took it back we explained to them that our warranty was almost up and that there was something very wrong with the four wheel drive and we took them on a test ride so they could hear the noise. This time they heard the sound when we pointed it out but dismissed it as normal. It was clearly was not normal and could be heard very loudly at this point. Third trip in and now our Avalanche was at a few miles over the 36,000 mile factory warranty, they took it for a test drive with us and tried to tell us again that the grinding noise in four wheel drive was normal but this time we insisted that they pull the drain plugs on the transfer case and front differential. They would only do it after we agreed to a one hundred dollar diagnostic fee. Turns out the transfer case and front differential were both full of metal shavings due to being assembled too tight internally from the factory. This dealer was just trying to push the problem out of warranty so they would not have to deal with it but after getting GM involved both the transfer case and front differential were replaced under warranty. We would not recommend this dealers service department to anyone.
