ELECTRICAL SYSTEM
When vehicle is turned on OR during normal driving, audio volume randomly goes to full high mode (all the way up) to a deafening level that makes it difficult to drive. The knob, steering wheel controls and any connected devices (like the phone) do not control the audio. Audio setting is completely unresponsive and will not turn down. It is not possible to drive in this condition. I had to pull over and turn my car off. I turned it on and off several times before the audio did not come on full blast and I could safely drive my car. This is the third time this has happened to me. Two out of 3 times I had a young child in the car.

ENGINE
Lifters failed 2nd time at 130k miles. Driving on highway at 70mph cruise and engine went to limp mode. Multiple repairs. $5,000. Dealer sold it to me in 2020 with 80k miles and did not disclose prior lifter replacement. I know they did something as a head bolt is missing.

POWER TRAIN
I bought a brand new Yukon Denali in 2021. In 2022 at 12,000 miles, the car was riding extremely rough. It was diagnosed as a transmission issue and the transmission was rebuilt after 90 days in the service department at a GMC dealer. Later in 2022, I started getting low oil lights on the dash. The car was brought back to GMC and I was told that there aren't any leaks evident so nothing was done. This happened repeatedly over the last 2 years, at multiple GMC service departments. No leaks, nothing to see here. Last week, the car started shaking violently while driving, with multiple warning lights appearing on the dash. Finally the car just died and I had it towed to yet another GMC dealership. This time I was told that the bearings, piston rings and lifters were all to blame and the car needed a new engine. Of course, now the car is out of warranty. GMC needs to remedy the engine issues in the 2021 models. There are MANY reports of this happening with this engine.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When driving through Eugene brakes suddenly got soft while at a stoplight, then pedal got stiff and very hard to keep pressed. An alert came on the dashboard 'Brake Assist Service' just about the same time the brake pedal changed and car would not fully stay at a stop. When checking to feel what had just happened, by letting up and repressing the brakes, it would not fully stop car, even with all my strength pressing. If another car would have been coming through, my young son or myself could have been killed or seriously injured and I could cause someone seriously to be hurt or killed from being in their lane of travel. I alerted my husband that I was unable to drive the vehicle safely, he is in the vehicle industry and looked up online and found there is a common known problem, recalls, and service bulletins, but apparently not for vehicle years prior to 2017, although this severe failure is seen on 2014 and later; and the manual tests/diagnostics that a person can do in a pinch per the bulletin, recall notice, and articles; and in his trials of how to tell if it is a failure or fleeting problem - nothing alleviated it, all the symptoms are present and system is failing and continually bringing up the brake assist service alert. This is the info that we found on the recall, but didn't appear to cover 2016 year models: [NHTSA campaign number: 20V603. GM's own number for this recall is N202300860.] We plan to get this yukon over to Guaranty Chevrolet in Junction City Oregon tomorrow 10/8. The only thing that has been very recently noticeable preceding this in recent week or so is a slight uneven braking feeling in the motion of the car when coming to a stop. Which it has not done before.

ELECTRICAL SYSTEM, ENGINE
While on a red light and foot on the break, the car turned off completely and would not turn back on after many tries. Truck was towed but mechanic did not find any issues with vehicle as he turned it on with no issues. All lights flashed and indicated battery was low but was not warned prior. The previous week, the truck shut off completely as well but it turned on quickly.

SERVICE BRAKES
I have noticed the amount of pressure needed to apply brakes at a slow speed is a lot to where it seems like I will crash into the car or object in the way of my vehicle. I took my vehicle to a GMC dealership and was told the brake vacuum pump needs to be replaced. These vacuum pumps were already recalled by NHTSA. NHTSA #19V645000, GM #N192268490. This recall was expanded to include additional vehicles. NHTSA #20V603, GM #N202300860. I strongly believe my vehicle needs to be included in this recall. GMC repair invoice is attached.

FUEL/PROPULSION SYSTEM
On 9/23/2024, I was driving my 2021 GMC Yukon Denali down the road, when the Engine seemed to lose power, and the accelerator no longer worked. There were no indications of any errors or alarms on the Dash, and all functions on the interior of the Cabin showed as normal. The vehicle switched into Neutral, and the engine shut off and I was unable to control or accelerate. This is a extremely serious situation and extremely dangerous in terms of Safety.

POWER TRAIN
While taking my children to school, the vehicles RPMs began to jump, causing the vehicle to lose power. Which resulted in myself and two children stranded on the side of the road. The vehicle had just crossed over 110,000 miles when the transmission completely broke apart from the inside. There was no other warnings or lights that appeared on the dash prior to or after. We had been given an estimate from GM for $6200 for a new transmission.. but that was extremely difficult to afford. We ultimately had to have the transmission rebuilt due to it costing $3,000 less, so we could continue going to work. We are still having issues with the transmission even after taking to back for a 2nd time to be reprogrammed. It’s extremely frustrating to have paid so much for this Yukon to have transmission go out with as many miles as it did, plus with no warnings.

ENGINE
Driving on highway and engine cut off with no warning. No dash lights to show a warning. 3321 miles on engine. The vehicle was unable to be put in neutral for the police to push it out of the highway. Three Moncks Corner police cars surrounded the vehicle to maintain safety. The vehicle was towed to the dealership. Needed a new engine and cooling system. The engine and cooling system were both replaced.

VISIBILITY/WIPER
Serious Safety Issue: While driving in the Rain, with the wipers on (actively working), randomly they will stop working. They will not work again until 10-15 minutes of time has passed. Any alternative setting makes no difference. During the 10-15 minutes of non-working wipers, there is nothing the driver can do…. Except wait. Depending where and when this occurs, this could be a deadly safety issue. I’ve checked the fuse; Turned off the rain auto-sensing feature – yet the vehicle is scary to drive in the rain, not knowing if / when the wipers may stop working again. During my ownership of this vehicle, this has happened three times; of course you must be driving during rain for the issue to occur.

SERVICE BRAKES, ELECTRICAL SYSTEM, SUSPENSION
i HAVE A SERVICE SUSPENSION LIGHT THAT CONTINUES TO POP UP ON DASHBOARD THE MOST IMPORTANT ISSUE THAT NEEDS TO BE ADDRESSED IS THE BRAKE LIGHTS. I have previously had the passenger side brake light stop working. In order to repair this you have to order a whole new taillight. My vehicle was approximatly 6 years old when this started happening. First incident (2022 with approximately 65000 miles) Yesterday, I was pulled over by a policeman and both of my brake lights are not working. We found a way to sauder (I know this is incorrect spelling) the broken metal piece back together in the taillight; however, this is not the correct way to fix the underlying problem and clearly it is only a temporary fix because the passenger side broke again in a new spot.

ELECTRICAL SYSTEM
The dealer claims it was a faulty battery. Said it had a short in it. I have the battery and it can be inspected. I firmly believe it was software related. I was driving and the vehicle completely shut off while driving. I was unable to steer, restart, use the power assisted brakes, or navigate to a safe area. I was unable to restart the vehicle and it had to be towed. The problem was never reproduced and has not occurred again. The vehicle was inspected by the dealer. All possible warning lights came on the dash and display. The radio and Bluetooth still worked.

ELECTRICAL SYSTEM, ENGINE
The servicing dealer identified a faulty injector wiring harness. A national backorder caused a delay in repair. I do not have the part. The dealer retained. I was driving at highway speeds on the interstate and every possible warning light came on the dash. "Service ESC" "Service Traction Control", Reduced Acceleration Drive with Care", "Forward Collision System Unavailable", "Service Emmision System" At this point, I experienced a loss of power and acceleration, and the vehicle would shake violently when I applied the accelerator pedal. There was no indication of any failure prior to the failure.

POWER TRAIN, EXTERIOR LIGHTING
My vehicle is currently in the shop getting the motor worked on for a bad lifter. From the information the mechanic provided me this is a common issue with the vehicles that have the Active Fuel Management system. They are seeing many of these vehicles have to come in and have very expensive repairs. My first quote I received was $16, 000, they told me I needed a whole new motor and this assessment cost me $365 and a rental car while they looked at the truck. Now it is in the shop again and the estimate is $6000 to machine the cams as there are metal shavings in my oil. I had to again rent a rental vehicle and have not had my truck for a week. This is the third mechanic that has seen multiple of these motors have to be replaced or repaired due to this issue. I kept up on my oil changes and other recommended car maintenance and so did the owner before me. I had my last oil change approx. a week before the loud ticking noise began, then my vehicle began to have a noticeable loss of power when driving and eventually began shuttering and my check engine light began to blink and I took it to the shop. A year ago I had to replace my tail lights. I was able to find where others were recalled by my VIN for some reason was not included in the recall. They started shorting out and working only part of the time which is very dangerous when stopping, especially at night. I had them replaced and paid almost $700 for the two back lights.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
1 Adaptive cruise stopped me several times for no reason as there was nothing on the interstate and the weather was clear. This was very jarring at 80 miles per hour on the interstate created a hazardous and dangerous driving condition as cars were all around, almost was rear-ended. 1a Adaptive cruise started all the sudden when I was stopped at an intersection almost caused a wreck, as soon as I took my foot off the break it speed up, but I was able to veer off and break several more times. The adaptive cruise should automatically go off when the brakes are applied. 1b Cruise control will not activate sometimes (it is intermittent). 2 Sensors do not work properly and do not go off to warn if I have driven to close to something, this has happened several times after I became aware of it and after front bumper was damaged. 2 Garage door opener works sometimes, this means I have to get out unlock the house go shut the garage door and relock the house... very unsettling. 3 Android Auto goes out continuously and will not reconnect even though the maps are still on my phone and everything is setup correctly. This also creates a hazardous condition when driving on the highway in unfamiliar areas causing me to miss turns and unable to navigate through traffic. 4 Seat, adjustable setting does not work when entering the vehicle, only upon exit. 5 Mirrors do not automatically fold when parking the vehicle as they did when I purchased the GMC. 6 Rearview camera doesn't turn off automatically after reverse parking has to be done manually while driving. There are so many issues with this vehicle. I have serious concerns with the safety of this Yukon. I have filed a lemon law with GM on the Yukon. The GM representative Lied in the abrtration stating there was a recall that would fix these issues....The dealer was notified within a week of the purchase but had me wait until GM had a software fix.... They stated the software update should take care of all the issue

ENGINE
The contact owns a 2015 GMC Yukon Denali. The contact stated while driving at approximately 20 MPH, the vehicle started decelerating with a slight clunking sound coming from underneath the front passenger’s side of the vehicle. The vehicle then lost motive power. The contact coasted to the side of the road and turned off the vehicle. After waiting for a while, the vehicle was started and the contact became aware that the instrument panel and all other electrical systems were activated as expected; however, the engine failed to start. The vehicle was towed to the dealer where it was diagnosed that there was a failure with the engine. The vehicle had not been repaired. The vehicle was then towed to an independent mechanic where it was confirmed that the engine had failed, and the starter needed to be replaced. The starter had been replaced; however, while starting the vehicle the engine emitted a loud rumbling noise which the dealer described as rocks being tossed around. The contact stated that the engine needed to be replaced. The vehicle was not repaired. The manufacturer had not been made aware of the failure. The failure mileage was 150,150.

The transmission malfunctions, shifting is inconsistent and shifts by itself. Shudders and causes the engine to increase and decrease in RPMS. This causes the engine to lose power. The truck will slow because of bad shifting and stall. The dealer did a diagnostic test and verified the transmission problem. The vehicle was inspected by the vehicle brand dealership. There were no warning lights or any other signs of the transmission failure.
