This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Bosch fuel pump is failing sending metal filings throughout the engine. GM is aware of the problem on vehicle years 2011-2106 but has not issued a recall. Cost to repair $10,600 plus loss of vehicle since the repair takes over 40 hours.
Vehicle developed a fuel leak in the return fuel line located at the tank. The fuel line is made of plastic, it has no protection around the fuel line, and is located where natural debris may collect. In this particular incident an acorn became lodged next to fuel line and wore a hole in it. The result was a fuel leak only when the vehicle is running/driven, and I was driving the vehicle at the time this occurred. The area where this fuel leak occurs is also directly opposite of the diesel exhaust system which reaches 1200 degrees during the regeneration process. While driving with this leak the wind turbulence created under the vehicle caused diesel fuel to be distributed across the entire underside of the truck including the exhaust system which could have caused a fire. There have been vehicle fires reported but since the lines are plastic any evidence of them being damaged is destroyed and the true cause of the fire left undetermined. This design defect should be looked at and corrected immediately to prevent any further property damage and harm to the public at large. I had the vehicle repaired and the dealer claims a rodent chewed through the line and caused the leak. The vehicle is garaged kept and I do not live on a farm, plus there are many other items in the garage that a rodent would prefer over the fuel line. I have a video and the fuel line and the 2 acorns. The problem could have been prevented either by putting a shield to stop the debris from entering, moving the tank back 4 inches, and/or wrapping the fuel lines with a protective covering.
Driving at approx 35-40 mph approaching a hairpin turn tried to break and vehicle did not slow down slid through the corner into a rock, put the vehicle is reverse and pressed accelerator the vehicle RPM increased on own tried to break the RPM did not diminish(foot off accelerator) before I had time to shut the truck off I hit a tree behind me. It appears something stuck in accelerator (mechanical) or the computer system( electronics) failed. The vehicle has not yet been tested.
While traveling on interstate 80, in Iowa, the fuel transfer pump on rear fuel tank malfunctioned causing a pressurization of the forward fuel tank which resulted in fuel spray to from the forward fuel tank fill-neck. To stop the continuous loss of fuel, I had to pull fuse #18 from fuse box under hood for the rear fuel tank fuel transfer pump to shut it off. Rear fuel tank capacity is 40 gallons and forward fuel tank is 23.5. I estimate a loss of 20 gallons on highway before I discovered the problem. This system runs the engine from the forward fuel tank, and the forward fuel tank level is maintained by a fuel pump which draws from the rear tank, not certain what caused this failure but if I had been sleeping in the truck, which I do as I operate this truck commercially for Transport of rv's, there is a good change that the loss of over 20 gallons on the ground could have ignited. Truck has been in shop for 3 days as of 11/7/14 and they have been unable to determine cause of malfunction.
On acceleration from a stop, the RPM's race while shifting. Vehicle acts as if the transmission is slipping from 1-2. early in the life of the vehicle I thought this was only something that happened the first time shifting after pulling out of the garage however, as the truck gets more miles on it, the problem happens more often and when taking off from stops when hot. Vehicle was brought to dealer to diagnose complaint and was told there was a bulletin to address this problem but since the tech couldn't verify it, they didn't do anything. Dealer said I have a good powertrain warranty so if something breaks later I should be covered. Not only is this unprofessional and poor customer service, they literally did nothing to attempt to diagnose or confirm the problem. There seems to be numerous complaints on this site related to RPM racing complaints.
