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.
Tapping or clicking noise coming from engine compartment. Car lost power, bucking with hard shifts, and stabilitrack, ABS and check engine lights all come on. I took to authorized repair shop and they found misfire on cyl 4. changed all spark plugs/wires and cleaned thottle body and tune up as well as oil change. Car continued hard downshifting after picking up. Drove for a week and symptoms reappeared again. Shop is currently trying to diagnose if it's a bad lifter(s) or possibly fuel injection problem. Shop owner admitted that he's heard of problems with GM's 5.3 engines and the active fuel management system wrecking engines. I have my 3 kids in the car and it was scary almost getting stuck in the middle of a busy street.
Traveling in the right lane of a four lane highway. Maneuvered into the left lane and accelerated under full throttle to pass another vehicle. After moving back into the right hand lane and releasing the accelerator pedal the vehicle continued to accelerate. Depressed accelerator pedal several times through its full range of motion to ensure that it was operating freely but that resulted in no change. Vehicle did not respond to accelerator pedal input changed. Seemed to be stuck at wide open throttle. Applied full brake pressure as hard as possible to slow vehicle as it continued to try to accelerate. Brakes began to get hot and brake fade was imminent. Shifted transmission selector up into the neutral position. Engine momentarily overran to the rev limiter and then settled at 4000 RPM. Continued to apply brakes to a stop while in neutral. After being stopped for approximately 30 seconds the engine slowed to normal idle speed. Throttle seemed to actuate normally again. Shifted transmission to drive and proceeded to the dealer. Approximately 30 seconds later the dash indicator "grade braking on" appeared in the mfd and then disappeared. I was traveling on flat ground at approx. 20 mph and not depressing the brake pedal. I confirmed that the tow/haul mode was not selected on the transmission. Proceeded to dealership and awaiting repair notes.
When braking or slowing down this Suburban acts like it wants to keep going, like a jerking motion forward and back, making the stop hard, as if it is trying to accelerate and brake at the very same time, because the rpms are constantly moving up and down switching from V4 to V8 mode. Going down hills and going up an short inclines the vehicle does the same jerking motion, forward and back until I come to a complete stop. When taking off and keeping a low speed under 35 mph the vehicle cannot maintain the speed, it acts like it wants to stop ( it never has died) but I have to punch the accelerator to get the vehicle to pick up its speed again. While I was in a school pick up line just coasting along around 10 mph, my foot was not on the accelerator or brake and the vehicle moved forward on its own. The issues seem to all happen at a low speed, from 0-40mph. I have taken this vehicle in to the Chevrolet dealership on several occasions for the same issues as I have described above. Each time they are unable to duplicate the issue. My biggest aggravation is that this vehicle does not do this every time I drive it, which makes it difficult to be duplicated. I am concerned that when I am coming to a stop that the vehicle will not stop and rear end another vehicle. This issue started around 2000 miles and has continued to this day, currently this vehicle has 7500 miles on it.
Vehicle was picked up brand new from the dealership, with approximately 1/8 tank of fuel. The fuel tank was filled, and the following day, shortly after leaving for a trip, a grinding/rattling noise started. Inspection under the vehicle revealed the front of the fuel tank was approximately 8-10 inches lower than the back, and the strap to secure the tank to the vehicle nearly on the ground. A metal guard on the inboard side of the tank was rubbing against the driveshaft, causing the noise when driving. After towing to a dealership, tank was fixed, and dealer service remedy stated "front fuel tank strap was not seated in frame, tank fell when filled up, tank and shield damaged, replaced fuel tank, front strap and shield front tank left side".
The contact owns a 2013 Chevrolet Suburban. The contact stated while driving 19 mph, he traveled over a road bump and the vehicle stalled. The vehicle was taken to a dealer for diagnosis and the contact was informed that the fuel pump fuse would need to be replaced. The vehicle was repaired. Two days later, the failure recurred. The vehicle was towed to the dealer and the contact was awaiting diagnosis. The failure and current mileage was 3,500.
