SERVICE BRAKES, ENGINE, FUEL/PROPULSION SYSTEM
I call this a "Panic breaking defect" I have experienced this on two different GMC vehicles manufactured 14 years apart. The first was a 1999 GMC suburban with mechanically operated throttle control. The second was my present GMC Yukon XL Denali with electronic throttle control. The defect: The close proximity of the accelerator pedal to the brake pedal makes it possible to have the right foot on both pedals at the same time. This results in high engine RPM and full breaking pressure, however, the anti-lock breaking system releases and re-applies the break pressure repeatedly allowing the vehicle to lunge forward a short distance on each cycle. To remove ones foot from the both pedals so as to apply it to just the break would result in the vehicle, engine being at high RPM, to allow the vehicle to speed forward resulting in a serious collision. True one could use the left foot, if able, on the break and then remove the right foot, allowing the engine to return to idle but on modern automatic transmission equipped cars where the left foot plays essentially no part in driving, such an action is not likely to occur. Also the ignition key could be turned off but with both hands employed to apply maximum pressure on the steering wheel to ensure maximum braking effort, that is not likely to occur either, besides that would result in lack of power steering and vacuum boost to the break system. A proposed solution: In a drive by wire environment it would be simple to send an idle signal to the throttle body every time the break pedal is pressed and this is the condition which occurs in a normal breaking situation. I have related this to the service manager of my local dealer and have also communicated it to General Motors Customer Support even offering to demonstrate the problem but have received no response. After all I am only a lowly customer and it matters not that I am also a retired Engineer!

POWER TRAIN
I currently have 109024 miles on my yukon. At the time the issue first occurred, it had 108998 miles. Up til that moment, it was running perfectly. About 5 miles into my drive on 11/13/2022 it started to shutter at the top of 2nd gear, then a hard shift into 3rd. The shutter repeated at the top of 3rd, before a hard shift into 4th gear. I turned around & returned home. Checked the fluids, everything was fine. Let it sit, had to drive it to work (6 miles or so) on 11/14/22 & it shuttered at the top of 2nd & 3rd gear again. Took it to Wallingford Buick GMC (in CT) Tuesday 11/15/22. Upon inspection, it was confirmed the transmission failed. $6538.31 for a new, replacement transmission. It's still at the shop, waiting for the new transmission to be delivered. I've maintained my vehicle, have regular oil changes & inspections of the powertrain components. This came totally out of the blue. No warnings, or any indication of pending doom.

AIR BAGS, SEATS
Service Safety Restrain System message keeps appearing after taking to dealer a few times. It will go off and on intermittantly and not sure the airbags are actually functional. This seems to be a common issue based on an internet search across multiple GM products that does not have a known fix. Also, the driver seat shifts slightly when making turns.

The contact owns a 2017 GMC Yukon. The contact stated while driving at 20 MPH with her daughter in the rear passenger seat, the message "Grade Braking Active" was displayed. The contact stated while making a right turn in an intersection, she depressed the brake pedal to prevent the vehicle from colliding with the vehicle before hers. However, the brake pedal went down to the floorboard and failed to respond. The contact then quickly veered to the right to prevent a crash. The vehicle hit a curb and was propelled to the left across three lanes and crashed into the rear of another vehicle. The air bags did not deploy.

POWER TRAIN, VEHICLE SPEED CONTROL
We first noticed the vehicle's lack of power and sudden increase when driving at a stop light/sign. We checked and REPLACED spark plugs, cables, coils, and a new battery. We became highly concerned when the vehicle would accelerate while driving and the RPMs would toggle between 500-1500 RPMS without pressing the gas. We immediately took it to an authorized mechanic, who found excessive noise from the transmission area and found debris/metal. No codes were present when a system performance was done. The vehicle only has 68806 miles on the odometer. The transmission had to be fully replaced, which cost over $7k. The replacement was done. This seems to be a common issue (Transmission replacements) with this vehicle as now we're hearing more about it. PLEASE check this as we could have easily been in an accident from the loss or increase of power without notice and NO WARNING lamp indications. This was a very expensive repair caused by the manufacture and not user error. We paid a lot for this particular vehicle and certainly love it but am concerned about this expensive safety/mechanical issue. Please call me for any questions[XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

SERVICE BRAKES, ELECTRICAL SYSTEM
I own a 2021 GMC Yukon Denali that had TOTAL BRAKE FALIURE last Tuesday. I had it towed to a local GMC dealer and are repairing it under warranty. I was lucky to be on a back road when my brakes went out. I had no warning lights come on prior to hitting the brake pedal and was able to coast to a stop on the shoulder When I applied the brakes, the pedal went to the floor and did nothing. You can't stop the car with the parking brake because it is electric. My concern is what if I was on a busy road when this happened or what if this happens to a family in traffic they could be seriously hurt or worse yet killed. I do have good photos of my instrument panel with all of the warning lights coming on after I tried to stop. In good conscience feel that I have to at least try and report this to GM, the state and anyone else that will listen. If nothing comes of this at least I tried and just hope no one gets hurt if this happens again. My wife refuses to ride in that vehicle until I have solid answers. The dealer said they will have my car repaired this week and are replacing the master cylinder and ECS This is fine but why did it happen and how can I be sure it won't happen again? I believe in GM and have a 2023 Yukon Denali on order. I would hope that after 3 years of this model they have most of the little quirks worked out. A rep from GM did contact me and at first was talking about buying my car back but changed that today. My case number is 9-8497380349 . The problem is I have no idea when my new car is coming in our should I just cancel it and find something else. In my opinion this is a very serious problem.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
State Farm is investigating the accident to see what, if anything, malfunctioned in my braking system. I ran a red light but when I pressed the brake upon approach of the red light my brakes didn't catch and so when I pressed them, I kept going at the same speed. I was going between 30 and 40 miles per hour I believe. Three cars were involved. I have a sore neck, chest, and burn marks in my neck region. I suspect my truck will be totalled. We performed routine maintenance on the vehicle. It had a little over 100K miles on it at the time of this wreck. There is not a recall on braking for 2014 models, but I see there is one for 2015.
