SERVICE BRAKES, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
The computer malfunctions. It is available for inspection. The computer lights up and causes failure in the trailer brakes. Glenn Polk the dealership in Sanger Texas has been working on a fix but has yet to come up with one. I have spoken with General Motors Representatives several time trying to resolve the problem without result. I also emailed the CEO last Friday and have heard nothing. There were no warning lights until seconds before failure.

FUEL/PROPULSION SYSTEM
While driving carrying a full load in the back of the truck, the engine began to lose power, started running rough and then died without any warning within a matter of seconds. No indicator light or warnings were displayed. We were traveling in the number one lane during heavy traffic and had difficulty trying to stop with no power nearly causing an accident. We were left stranded in the fast lane of a large intersection during heavy traffic causing a large traffic jam. The vehicle was towed to a mechanic who found metal shavings throughout the fuel system indicating the high pressure fuel pump had disintegrated internally causing the metal shavings. I have asked the parts be saved for further inspection if necessary. The mechanic stated this type incident has occurred and is a well documented and known deficiency for this make and model of truck.

SERVICE BRAKES, ENGINE, SUSPENSION
On Saturday, May 22, 2021, My wife was returning from fairgrounds in Waxahachie, TX. She remote-started the car, and the vehicle started. As it started to rain and was getting muddy, and the grounds are in a grass field (No large rocks, hills or debris to climb as it's cleared land), she shifted the vehicle into 4wd high incase the field was slick. She started to drive and received several warning lights, "Service ESC, Service traction control, brake light warning and check engine light". The vehicle also had a noticeable wobble to the wheel and felt off balance, jerky, and had speed limited. My wife turned the vehicle off and back on and some of the lights went off, and the vehicle did not lurch or wobble anymore. The vehicle had a tire changed at the dealer the day prior, so I am unsure if that tire change is related or not. Now the vehicle shows an alert "check engine, service emissions system". I am having the vehicle towed to the dealership tomorrow for diagnostics. All lights except the check engine light have since turned off since powering off the vehicle.

ENGINE
Truck was purchased on 11:28:20 and had my first oil change in March. Started noticing a ticking sound coming from the motor but it was. Very faint. After a while it went away. After a few weeks later the noise started to get louder and started shaking. Took to the near mechanic and he diagnosed it with bad lifters on the passager side.. I took it to another mechanic where their replaceming all lifters for 4.8k. This truck is not too old and I shouldn’t be replacing any engine parts. It only has 100k miles and it’s a 2016.

AIR BAGS
I'm frustrated with the dash being cracked. the big issue is that i believe it is a safety issue. the dash is cracked around the airbag area. if this airbag should deploy someone could be hurt or killed. I would like to get this corrected because I'm afraid to operate the vehicle. Thank you for your attention in this matter.

SERVICE BRAKES
Vehicle was 300 miles out of warranty when I get a service trailer brake warning on my info center replaced a blown fuse and the fuse blows again, no trailer has ever been hooked up to this truck. Went online and inquired about this problem and there's thousands of post and complaints about this problem, even on a GM site there's a PI investigation about this problem, why doesn't GM just do a recall to fix a problem they know about. I'm getting ready to buy a travel trailer and now I don't know if its safe to pull it!

SERVICE BRAKES
Whenever I connect a trailer to my vehicle I will lose all brake pressure when in reverse. It only happens when in reverse and connected to a trailer. I will have to pump my brakes to the floor and there's no braking power. This does not happen when I do not have a trailer connected.

ENGINE, POWER TRAIN, SEATS
-Engine gas consumption state 21 MPG Highway, 17 MPG Combined and 15 MPG City. When I started using this vehicle during the first weeks and months the best MPG I could get at the highway is 18.5 MPG with top tier gas such Shell & Chevron during the first 2 years and now Costco brand. Every since I bought it, the gas MPG have gone down around 0.5 MPG. The vehicle feels that it has to use more gas in order to perform. -The motor oil pump at times moves down from the 40 mark to the 20 when idle at traffic light and when it starts moving, it temporarily moves to the 60 mark. -The transmission is an 8 speed automatic. It has issues shifting to first gear, second gear and times 3rd gear. When driving at slow speeds like in traffic jams, mall parking lots or when you slow down at the traffic light and then turns green and you start accelerating again it feels harsh on gearing down and up, like someone rear ended your vehicle. -This truck has the Active Fuel Management (AFM) and it turns on even slower speeds and you feel how the engine and transmission struggle to really gear up and down. Like it never gears and tries to accelerate at a higher gear. Like in manual transmissions when you accelerate on a higher gear than at correct own it takes forever to reach the needed speed. -Even if all 8 pistons are on it feels as if I am running on a smaller engine like a V6 or V4. -The driver car seat feels that move a little like an 1/8 of an inch. -It just feels that something is wrong with motor and transmission.

AIR BAGS
Airbags failed to deploy after striking a street light pole head-on. The impact hit just right of dead center of the grille and shoved the front end back approximately 2 feet into the engine. There were no dash lights or warning lamps illuminated before the collision. I have notified GM and received a case number. I also have filed an insurance claim and the vehicle has been inspected by a reputable body shop and has been deemed a total loss. A police report was also filed. The vehicle is scheduled to be picked up by the insurance company on 5/18/21.

ELECTRICAL SYSTEM, SERVICE BRAKES, UNKNOWN OR OTHER
I was towing a camper down Rt 422 in Butler, PA in my GMC truck when it suddenly caught fire. My wife was following me and alerted me to pull over as quickly as possible. I had no brakes and the gear shifter went straight up without shifting. The doors would also not open while the truck was filling with smoke. I got out using the manual unlock knob and am lucky to be alive. We had about one minute to try to extinguish the flames before it fully engulfed both my truck and camper. I filed a complaint with GMC. By what I am reading online there are many instances of fires and GMC does not seem to provide assistance. This is very unnerving and scary to say the least. I am sad and angry for this situation. This happened through no fault of my own and I lost absolutely everything. I was in the middle of moving to start a new job and lost many work items in my truck as well. I had to delay my start date for work. Now I am responsible for deductables, insurance increases and other items not covered by my insurance. Now I have to buy a new vehicle and camper but what will GMC do to help me? Probably nothing.

I LEFT HOME TO GO TO THE STORE. WHILE DRIVING ON THE HIGHWAY MY SUNROOF EXPLODED. THERE WERE NO CARS OR TRUCK IN FRONT OF ME OR PASSING ME. NOTHING HIT MY TRUCK. IT SOUNDED LIKE A SHOTGUN GOING OFF INSIDE THE TRUCK. THE SUNROOF EXPLODED SENDING GLASS EVERYWHERE. I WAS DRIVING ON A 5 LANE HIGHWAY, IT WAS RAINING, BUT NOT A BAD STORM. THE ROAD WAS STRAIGHT AND IN GOOD CONDITION. IT HAPPENED SO FAST I DID NOT KNOW WHAT WAS GOING ON. I PULLED INTO A GAS STATION TO CHECK MY TRUCK. I FOUND GLASS ALL IN THE BED OF THE TRUCK AND MOST OF THE SUNROOF GONE. I HAVE TAKEN IT TO THE DEALER AS THE TRUCK IS UNDER WARRANTY. I WAS TOLD THE WARRANTY DOES NOT COVER DAMAGE AND SO FAR NO ANSWER IT THEY WILL COVER IT. I HAVE HAD THE TRUCK FOR ALMOST 3 YEARS AND IT IS NEARING THE END OF THE WARRANTY.
