General Motors LLC (GM) is recalling certain 2020 Cadillac Escalade, Escalade ESV, Chevrolet Camaro, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The fuel pump may be missing a pressure regulator, allowing for over-pressurization of the fuel system.
The transmission failed on August 8, 2026, while I was driving on a highway. I moved safely to the shoulder, but the vehicle became inoperable and required towing. The loss of propulsion in active highway traffic created a potentially hazardous situation. My GMC Bommarito Buick GMC dealership advised that GM cannot currently supply the required replacement transmission. The dealer has no estimated delivery date and does not know when GM can supply the unit. The vehicle has been out of service for over four weeks, with no definite repair or return-to-service date. I am concerned that the inability to provide a replacement transmission may indicate unusually high demand or a broader issue. I identified other recent NHTSA complaints involving 2020 GMC Yukon XL vehicles reporting 10-speed transmission failures and difficulty obtaining replacements, including ODI complaints 11711773 and 11747021. I request that NHTSA evaluate this complaint with similar reports. I respectfully request that NHTSA consider whether: • These transmissions are experiencing premature or unusually frequent failures. • Valve-body, internal, or other component defects may contribute. • Failures can cause sudden loss of propulsion, unexpected shifting, loss of power, or other safety-related conditions. • The replacement-transmission shortage is connected to an unusually high failure rate. • GM has sufficient replacement units and repair components available. • Available complaints, dealer information, and manufacturer information warrant further investigation or action. I request that this complaint be associated with my VIN and reviewed with other complaints involving 2020 GMC Yukon XL Denali vehicles and other GMC, Cadillac, and Chevrolet models equipped with the 10-speed 10L800-speed automatic transmission. I believe the circumstances warrant review as a potential broader vehicle-safety issue, rather than solely an individual parts-availability problem.

Passenger door handle caused laceration in my sons hand. Peeling interior paint or chrome created a cut on hand. Causing it to bleed and get first aid. Noticed all door handles were in same condition. Very un safe and can repeat incidents like this to other in household.

The vehicle has an unpredictable and random tendency to hesitate when the gas is pressed. This has been happening at some level since the vehicle was new. The dealership service department was never able to get the vehicle to do what I was concerned about, so they never helped resolve the issue. Now that it is out of warranty, the issue is getting worse. It is to the point that I believe it is unsafe for anyone but me to drive it. I have to make sure that when I turn onto a new road, that there is absolutely noone coming because I cannot depend on my vehicle to accelerate quickly enough, even at a normal rate. It may lag and take its time speeding up, or it may accelerate normally with no issues. I stopped going to the dealership for oil changes and checking the issue because they no longer give loaner vehicles and they take a minimum of three hours for an oil change. So I recently took it to my trusted mechanic. He replaced the knock sensors, which helped slightly. He could still detect issues, but was concerned it would require a whole new engine built to bypass the DFM system and repair the cams and lifters. So I nw have to drive a vehicle that needs $20,000 worth of repair, has the potential to be dangerous or leave me broken down on the side of the road. It has 106,000 miles and I still owe $12,000 on it. From my research, I understand that this is a known issue and that there are several lawsuits regarding the issue. That does not help the average person who doesn’t care about a lawsuit, but is justifying st trying to live their average life with a dependable vehicle. Please help!

Without any indications of a problem our transmission began making a loud whining noise. The evening before it was fine and the next morning on startup the noise just began. The Vehicle only has 45,000 miles on it and the transmission had been serviced at the recommend manufacturer interval. Took it immediately to my auto repair shop where it was diagnosed as a transmission failure (they has seen this before) and told not to drive until replaced due to safety issues related to the failure. Unfortunately, due to a shortage of these needed 10 speed transmission I waited over a month for the vehicle to be repaired. The shop contacted GM to inquire about any warranty help but was told there was none.
