I hit a bump and both rear shock mounts blew off the rear cross member because the frame is rusted out despite having rust protection. It is available for inspection. The truck then began bouncing wildly. Meanwhile the underside of the bed isn't rusted at all, not one speck. It just seems weird to me, reminds me of the Toyota frame problems from a while back. It has not been inspected by a mechanic or insurance, my insurance company didn't seem to care in the slightest. I have had traction control and abs warnings on for a while but my mechanic said that was a faulty tire sensor.

“Faulty fuel pump driver module” part Not available for inspection. Repaired at dealership and they kept the part. While driving 75 mph on the interstate during high traffic time my GMC Sierra 3.0 diesel truck engine shut completely down, not just once but on several occasions putting myself and three other in a life safety situation due to the traffic around us at the time. I had to navigate the truck through traffic and off the road. Once there the vehicle was turned off allowed to sit for a few minutes and restarted. The vehicle would restart and we continued only to have this scenario repeated again several times. Faulty fuel module was diagnosed by mechanic at dealership and replaced. Part was not inspected by no one to my knowledge except the mechanic. There was no prior warnings before this incident happened. After the incident the engine light came on with a message that stated check ESC.

I have a 2016 GMC 1500 Sierra Denali and experiencing a very scary problem that has suddenly developed with this vehicle. As I am parking or in a slow turn, the vehicle completely looses all power [engine, electronics, brakes, etc..] and the steering wheel jerks out of my hands and then a second or 2 later it comes back on and then repeated 2 more times as I was attempting to park. I had this happen while turning into a parking spot at the store. Then the next day it did it a again as I was turning into a different parking lot. I loose complete control of the vehicle. I have been lucky not to hit another vehicle, more specifically a person. I decided to park the vehicle at home and not drive it until I get GMC service to diagnose. I have an appointment at a dealership to diagnose the problem on 08-15-204 at "Chevrolet Buck GMC of Puyallup Inc.". I did some research on the internet and found a site where others have experienced the same problem. I looked for recalls yet none are concerning my vehicle, however I did find a recall# N202325410 that fits the entire issue for some earlier vehicles. Same exact problem. Something to do with the steering column electrical harness. Please advise what recourse I have?

- #11608202August 13, 2024EXTERIOR LIGHTING
At night, when put into reverse, the exterior reverse lights do not illuminate enough to safely use the rear view mirror or backup cameras to safely navigate in reverse. I have owned a new vehicle every other year for many years and I have never experienced this any any other vehicle. I am going to look at aftermarket lighting options to be used when in reverse. This is a very big miss and safety concern on any new vehicle now days, let alone on a $80,000 pickup truck.

Engine goes to limp mode multiple times 3 of which happened getting onto the highway and almost creating an accident due to the reduced acceleration mode. CODe u0656 00 popped up each time. Dealer has yet to rectify due to lack of appointments… making me keep the vehicle saying it’s drivable but each time randomly goes into the reduced acceleration mode every restart.

I was driving down the highway at 65 when the upper front hood molding flew off and bounced off my windshield. There were motorcycles behind me but none were hit. After researching on [XXX] , many others have had the same thing happen. This could have broken my windshield, or worse, hit a motorcyclist behind me causing a wreck. It has not been inspected but reported by many others on GMC forums. There was no warning whatsoever. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine locked up on the truck due to bad lifters. It has the 6.2L engine and after talking to several mechanic shops and research online this is a very common issue. GM is having to put lots of new engine in under warranty due to this issue. They need to have a recall to fix a known issue that is costing people thousands of dollars to replace the whole engine in the truck. We was driving down the hey today and with no working at all the truck died and and would not crank back over. We had the truck towed to a repair shop to find out that our truck had the same issue that lots of people are having and now it’s gonna cost us several thousand dollars to have fixed when realistically GM should be paying to fix this problem.

Noticed a/c getting warm. Attempted refilling Freon without success. Took by auto shop and they discovered the welds to the top driver side of the condenser were in question and ruptured causing a Freon leak. They advised a replacement and stated “this is very common with GM model trucks and SUVs. Save your info and report for recall. They need to recall these models for their a/c issues.” Condenser replaced with receipt attached

The engine of the vehicle malfunctioned. The vehicle is available, but however it was taken to a certified dealership to be repaired. My safety and the safety of my three nieces, who were in the vehicle at the time, were put at risk as the vehicle all of a sudden staled in the middle of the Interstate while driving at 75 miles speed rate. The dealership repaired the vehicle by replacing the engine because the camshaft was scored, one of the lifters had failed, and a pushrod was bent. The only warning lamp/message was at the time of stale which read service ESC, Service parking break, and there was a third message but could not remember. I have only had the vehicle for sixteen months. The vehicle was taken in for it regularly scheduled oil changes and tire rotations. There were no issues or warnings prior to the engine replacement which cost me $8623.00.
