ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving and all my sensors came on stating they needed service including front camera, blind spot notification, lane departure, emergency braking etc. upon parking I exited my vehicle and walked around the rear of my car to find multiple wires hanging down burned from my exhaust. I took my vehicle to an automotive repair shop and not the dealer since it was no longer under warranty. They said they had never seen anything like it. It appeared the harness that holds the sensor module/wires disconnected from the car. It appears to be held in place with some sort of industrial glue. When it failed it was hanging in front of the exhaust and melted all of them. This disabled all of these sensors. I now have to pay for a new harness and to replace all of these sensors. In researching online it appears water intrusion has caused issues in some models and caused these harnesses to fail. I’m wondering if this is the cause even though this model isn’t part of the recall.

SERVICE BRAKES
The service trailer brakes alarm will just off incessantly which is a major safety hazard and it’s due to faulty wiring. I’m not happy about this at all GMC needs to recall these vehicles.

EXTERIOR LIGHTING
My issue pertains to a known problem. The driver's side tail light has failed. GM issued Special Coverage Adjustment N182180270 because of this issue where the part was covered for up to 6 years or 72k miles. Mine failed after 6 years and 4 or 5 months at 66k miles. It's utterly ridiculous that a defective, $800 light is fine to break after 6 years with no warranty assistance.

POWER TRAIN, ENGINE
The torque converter is too small for the vehicles transmission which then caused it to break and put metal into the transmission fluid. Which cause the transmission to break. My safety was at risk was because while on highway it shot high on RPMs and then made funny noise and wouldn’t go. The problem was confirmed at Aamco transmission where I have to get the transmission rebuilt. There was never a check engine light or check fluid or any codes Thrown before the problem.

AIR BAGS, ELECTRICAL SYSTEM
I was involved in a traffic collision. A large vehicle turned left in front of me and I t boned that vehicle. We were traveling about 30-35 MPH at the moment of impact. My vehicle sustained major damage ($20,000+) to repair according to the body shop. My wife, daughter and myself sustained injuries. My wife and I have significant injuries. I truly believe, based on vehicle damages, and injuries that our airbags should’ve deployed. I believe it has a fault sensor that should be inspected.

POWER TRAIN
My GMC Yukon Denali xl has a defective transmission from the manufacturer thousands of other General Motors customers are experiencing the same issues since 2015 General Motors has still failed to issue a recall. This problem cause the truck to leap, lunges and sometimes accelerate as well as hard down shifts which causes sudden stops this also causing severe damage over time. There’s also defective paint peeling and fading from the manufacturer

POWER TRAIN:AUTOMATIC TRANSMISSION
My transmission has issues shifting between 1st and 2nd gear. It has for several years. I have brought it into the dealership several times. They fix a part but when I get the car back, it’s still experiencing the same problem. When Accelerating, the car jerks between 1st and 2nd gear right around 10 miles per hour. It is a hard jerk that feels like you’ve been hit from behind.

SERVICE BRAKES
I purchased this vehicle, new. I have never towed anything with this vehicle. Yet, the "SERVICE Trailer Brake System" warning has been flashing, endlessly for two days. The chime is distracting when it comes to driving and/or hearing emergency sirens, should they be nearby. I have not taken it in for service as this just occurred yesterday (4/27/2022). This issue makes the vehicle difficult to drive and feel safe.

SERVICE BRAKES, STEERING
While driving on the freeway at 75 mph I felt significant reduction in speed and the rpms went pretty high. It felt as if I had my foot on the accelerator and the brake at the same time. There was also a burnt smell. After a few minutes it went back to normal. This continued to happen sporadically so I took it to my mechanic he inspected the vehicle could not find an issue he also ran a code scan. No codes pertaining to this issue only knocker sensor and O2 sensor. I replaced those anyway. Then a few days later I was driving to work at it happened again going about 55 mph it felt like the transmission had downshift to a very low gear there was smoke and really bad burning smell. I pulled over immediately and called my mechanic. He towed the vehicle to his shop still could not find a problem. After several months of sitting I had to drive the vehicle home. After approximately 5 miles there was smoke and small flames coming from behind the front drivers side wheel. My mechanic checked the brake, it had engaged without me pressing the pedal and stuck. Now we are having issues getting brake fluid to the rear brakes. Possibly the proportioning valve.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
The vehicle had a total failure of its rear safety package which includes blind spot monitoring, rear cross traffic alert, rear parking sensors and rear safety alert. The warning illuminated on the dash that all of these functions were offline and service was needed. We took the Yukon to a GM dealer and they replaced a computer and had a hard time getting it to program. This failure also affected the HVAC system in the car, with the fan staying on high. After 23 days of service, the dealer thought they fixed it. After two weeks of having the vehicle back the same alert came on 5-6 times in the same day, with another safety package failure. Now the alert doesn’t come on but none of those safety features work, they are all offline. It is bad enough driving a 20’ long vehicle without the safety package working, but now it is worse in that the car doesn’t alert you to the fact it isn’t working and you might not remember that it is defective. This could cause a collision on the highway or result in the driver backing into something or someone, relying on this technology.
