I was driving on the freeway with my family when the dashboard lights went off and the car started making a noise. The car then started shaking and I immediately pulled over. I was with my family and my children got scared. Previously to this the car had not shown any signs of problems. I had the car towed to the dealership. I received a call 2 days later from dealership stating my car needed a new engine. The car only has 42K miles and has had all oil changes.

ENGINE
At approximately 500 miles, the vehicle started to shutter and misfire at highway speeds (60-70 mph). The check-engine -light began to flash at the same time. We have a video and this happened 3 times before taking it to the dealer. This is a safety concern because it began to lose power on the highway. The issue was confirmed by the dealer and found to be damaged connecting rod bearings.Gm engineers are aware of the vehicle and would not approve the ordering of a new engine by the dealer until the engine was completely torn down to the point of failure.

ENGINE, FUEL/PROPULSION SYSTEM
Recall for engine propulsion. Say that there is no remedy yet. I have read the warnings about what may happen and I am terrified to drive the vehicle. GM says to contact the dealer, dealer says to contact GM. No one wants to take initiative. If they cannot fix the car, they should buy the car go back so I can get something different. I have been driving an old car around because I’m am afraid of this one. Please help me.

ENGINE, FUEL/PROPULSION SYSTEM
On the morning of Thursday, [XXX], our 2022 Yukon Denali departed from West Richland, WA with the intent to arrive in Spokane, WA. After a short stop in Ritzville, WA around [XXX] local time, we entered the freeway ([XXX] to Spokane, WA) and attempted to pass a semi-truck. The vehicle got to approximately 60mph and then began to rev without any propulsion to increase speed. The vehicle shut off completely and stated that we were to put the car in neutral and attempt to restart. While going 50-60mph, we shifted into neutral and attempted to restart without any success. While the situation was extremely dangerous give the traffic (semi-truck on the right and an approaching vehicle directly behind us), we slowed the vehicle and maneuvered to the shoulder where we stopped the vehicle. The vehicle would not start so we leverage the OnStar system to call a tow truck. Unfortunately, there was no ride available being 1-2 miles outside of Ritzville, WA where transportation services do not exist. We requested the help of WA state troopers who picked up 7 of us (4 separate trips) on the side of the highway. The vehicle was towed to Spokane, WA and we were left to fend for ourselves to get to Spokane. The vehicle is in the shop and we are told based on the codes achieved that it is a full engine failure.

ENGINE, FUEL/PROPULSION SYSTEM
After only 47,000 the Yukon started with hard starts and triggering a check engine light. Owner suggested fuel issues, the dealership suggested a bad wire. They adjust the "bare wire", and mentioned that the fuel pumps on these vehicles have issues and they would order one- but give them a holler when we have additional problems. The Yukon continued to hard start, evolving into stalling when started. The dealership was alerted but due to lack of engine codes being stored the dealership couldn't help us. Eventually when driving 57mph, the Yukon cut engine on a busy route, driver was able to get the Yukon to the shoulder and attempted restart- the Yukon was dead. AAA attempted to battery jump the Yukon without success. We were without our Yukon for 8 weeks, being placed in random trucks that couldn't support our family size. Upstate Chevy of Attica was not help in the process. We did contact GM directly and received a case number 9-14907008493. The engine was replaced. The Yukon still doesn't seem to be 100%, with some slow to starts. We are asking for compensation toward another GM full size SUV. We are GM friends and family and have purchased several vehicles over the years. We'd like to trade our suv now for a new 2025 without engine issues- but since our Yukon was gutted, that is now noted on a carfax which devalues our trade.

POWER TRAIN
Total valve body failure in the transmission at 30k miles. I was traveling with my daughter on the freeway at 65 mph and the vehicle went into limp mode. No indication of problems prior to this incident. Vehicle has been at dealer going on a month now. They have no valve bodies available, on a national backorder. They replace it with the valve body that is known to fail again. GM knows about this problem and the solution they offered was only a software upgrade so the back tires don't lock up when this happens. My daughter and I could have been seriously hurt or killed.

ENGINE
Check engine light came on. Immediately went to reputable local repair shop. Shop advised push rod bent due to faulty engine. Advised to call GMC because not normal wear and tear. Called GMC expressed my frustration about this being preexisting issue w this engine. GMC corp told me I had to ship to GMC dealership at my own expense then they could help me. Local GMCs backed up 6-8 wks. Towed car 1.5 hrs away. Mechanic told me not to worry this happens all of the time, GMC will take care of it. Pointed out a row of new trucks with my incl new Escalade with same issue. I spoke to a sales rep about trading my car in for new but he said engine issue still not resolved. He advised me to lease Escalade for $900 because by the time my engine blew my lease would be up; if not GMC fix under warranty!! Mechanic said new engine but GMC will take care of it. I waited 3+ months for GMC to authorize repair. GMC said they did not get docs but mechanic sent me verification of conversation and repair order sent to GMC. Mechanic received an unrelated warranty from GMC that said my issue was not covered. Mechanic said docs sent made no sense bc he sent the right warranty and he was sorry and embarrassed by GMC behavior. I finally paid over 14K for new engine. Picked up my car and drive a block and car still knocking and engine light came back on. I had returned my rental and no way home. In tears dealership gave me my rental keys back still all at my expense. The mechanic calls me two days later to tell me my torque needs to be replaced. I am hysterical, 14k spent, and car still not fixed. GMC told me to pay additional funds for torque converter or pick up. Threatened to charge storage fees. When I discussed their liability GMC became very rude and antagonistic. They cut off my communication with their lead mechanic. Took care of back to local repair shop. He said this smells of a law suit so would not touch vehicle. I all communication 106 more files to share.

SERVICE BRAKES
My wife was driving in the vehicle with our two (2) infants on Dixie Hwy in Boca Raton, FL when the breaks suddenly stopped working. Fortunately, there was not a lot of traffic on the road at this time and eventually the vehicle slowed down and no one was injured. No warning lights came on. Once the car came to a complete stop my wife turned off the vehicle and started it back up; still no warning lights or anything. My wife drove a little further to get to a safer location (not in the middle of the road), unfortunately the car then completely stopped working and my wife was still stuck in the middle of the road...eventually a police officer (crash inspector) came to the scene and the car was towed to the dealership for repairs.

UNKNOWN OR OTHER, ENGINE
I own a 2023 GMC Yukon Denali with the 6.2L V8 engine. A safety recall was recently issued for this vehicle due to a potential engine defect that could result in sudden and severe failure. However, GM has not provided a remedy, and dealerships are unable to offer any repair or trade-in options while the recall remains open and unresolved. I live in a rural area with limited cell service and long distances between towns. This makes the potential for sudden engine failure even more dangerous. Out of serious concern for my family’s safety, I no longer feel comfortable allowing my wife or our [XXX] child to ride in or use the vehicle. The risk of being stranded—or worse, getting into an accident due to engine failure—is too great given our location and the nature of this defect. I attempted to trade in the vehicle at a GMC dealership to get into a safer and unaffected vehicle, but the dealer refused to accept it because of the recall. This leaves me stuck with a vehicle that has a known safety issue and no solution in sight, limiting both my transportation options and peace of mind. There were no warning lights or prior symptoms before the recall. The issue was disclosed by the manufacturer. A dealer has confirmed the recall is active, but no fix exists. This situation is unacceptable and has real-world safety and financial consequences for families like mine. I urge the NHTSA to hold GM accountable and ensure a remedy is made available immediately to protect consumers who are left in limbo by this unresolved and serious safety defect.

Vehicle has 32,000 miles and the valve body has gone out and now parts for possibly months. My vehicle has been in the shop over these first 2 years over 2 months. Now this issue with the valve body it has been in over two weeks and they claim it will be months before they can get parts. This issue puts the vehicle in limp mode and most likely is damaging the clutrch packs as they go out. People all over the forums are having issues with these 10 speed transmissions. Something needs to be done to help out those affected.

ELECTRICAL SYSTEM, VISIBILITY/WIPER, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
I am experiencing ongoing issues with the infotainment system in my vehicle, which has remained unresolved despite multiple service visits. The system frequently blacks out, reboots while driving, and fails to function entirely at times, for days at a time. This is more than an inconvenience — it presents several serious safety concerns, including: •Loss of the rearview camera and parking assist features, making reversing hazardous. •Inability to access hands-free calling and navigation, increasing the risk of driver distraction and noncompliance with hands-free driving laws. •Disruption of access to climate controls and safety alerts that are routed through the infotainment system. •Frequent system crashes while driving, which divert my attention from the road. These issues compromise both the safety and usability of the vehicle, and I am requesting immediate action to resolve the problem under warranty.

ENGINE
The engine was missing and losing power with no check engine lights or messages at all, it is available for inspection. I was 3 hours from home in 4 lane busy traffic in St. Louis taking my daughter to a doctors appointment, losing power is not ideal for this situation and pulling over on the side of this busy road with my whole family in the car is dangerous. When I got the car home I took it to the dealership, they did an inspection and told me that my engine had 20,000 misses and I would need new lifters and a cam. I have not had insurance look at the vehicle since I had the dealership look at it, there has been a recall for this issue on these motors but somehow my vehicle is not on the recall list.

Transmission valve body went out, part is back ordered. There is a recall for this part on 2019 to current GM eight speed and 10 speed transmissions. This is clearly one of them. I’m not sure why it’s not recalled?
