Component: TIRES
General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5, GMC Acadia and Chevrolet Traverse vehicles and 2020-2021 Chevrolet Silverado 1500, GMC Sierra 1500 vehicles. The vehicles may have been manufactured with Continental tires that were overcured.
Consequence: Overcured tires may experience a carcass break in the sidewall resulting in a sudden air loss or could develop a belt edge separation which could lead to partial or full tread/belt loss. Either condition increases the risk of a crash.
Remedy: GM will notify owners, and dealers will inspect vehicles and replace tires that have DOT number and production mold number combinations identified by Continental, free of charge. The recall began December 17, 2020.

The diffuser component of the Roof-Rail Air Bag (RRAB) inflator may not have been properly crimped to the inflator and could separate from the inflator during air bag deployment.

Check engine light codes: P01F0; P0128 Engine coolant thermostat opening at a lower temperature than intended. Replace thermostat.
The torque converter in the transmission has been vibrating for over a year now. I can imagine it is causing more damage to the rest of the transmission. Now I can feel the shifting starting to get rough, loss of power, and dark transmission fluid. I had the problem confirmed with an independent service center. There have been no warning lamps as of yet. But it's only a matter of time that I will need a torque converter replacement and/or full transmission replacement.
The contact owns a 2020 GMC Acadia. The contact stated that the doors failed to open from outside the vehicle while using the key fob or while attempting to open the doors manually. The contact entered the vehicle from the rear hatch door and discovered that the door lock and unlock buttons were inoperable. The contact pulled the door handle to manually open the door from the inside. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 68,140.
Reduced steering assist came up on screen then as we went a few more miles the tire pressure on right front dropping like crazy for no reason on screen in vehicle stopped looked at tire no issues.
Failed component was thermostat and I do not have possession of it. Over several months, I would receive infrequent and unrepeatable messages of "steering assist reduced" and my temp gauge would drop all the way to the cold side. No other recorded codes were being set after frequent trips to Autozone for verification and there were no check engine light warnings. No other signs of vehicle malfunctioning were present either. Recently, a code was finally set P01F0, so I had something tangible to take into shop as the prior condition was not repeatable. Hoping it was only the coolant temperature sensor, then ultimately learned the thermostat had failed - the much more expensive repair option. Seeing this complaint relatively frequently with the 3.6L engine on NHTSA. Plus, the tech says he has changed at least 100 of these - Acadias, Traverses, Enclaves, etc., any GM product with this engine and poor design/position for the thermostat.
Rear heater line leak detected during evaluation of engine code P01F0 and empty expansion tank was noted. There was never any puddle in my garage prior to the incident, and nothing detected after the fact either. Pictures included demonstrate a leak at the double-crimp near the farthest rear point of the vehicle. The other hose behind the drip photo was also leaking at the crimp under the secondary piece of hose insulation. The design of the system requires replacement of the entire heater line assembly (4 pipes, associated hoses and fittings) traversing the entire length of the vehicle. I was told this is a dealer-only part.
After heavy rain or a carwash, the door locks and lift gate don't work from key fob. And the vehicle says no remote detected and has trouble starting. After a day or two they start working again. It caused U0422 (invalid data received from body control module). On forums it says it can be water leaking into the vehicle and shorting out the BMC from either the HVAC drain or a weatherstrip somewhere. Now my rear passenger door locks don't work at all. Dealer wants to replace the actuators but can't find the root cause of the problem. Issue has been going on for over a year now.
Engine coolant thermostat failed under 55,000 miles and had to have it repaired on my 2020 Acadia. The 2021 Acadia has a recall on the thermostat.
My front camera that detects the front collision and helps with adaptive cruise control just went dark. I thought maybe it would reset after turning engine off and restarting it, but it didn’t help. Not sure what happened.
1. Shift to Park failure, P0700/P187e internal sensor, causing me to have to get a rebuilt transmission. 10/2025 2. Transmission shudder/hard-shifting ongoing 2022-2025 3. Coolant/thermostat issues. Steering Assist Reduced" message, fans stay on HIGH, no AC, engine temp on ZERO ongoing since 2024 3. Start/Stop button failure multiple times (replaced 3 times) 4. Rack and pinion/steering gear (would not return/ got stuck while turning) got new rack and pinion 2023 5. Water pump leaking, replaced 4/2024 6. Since 2023, have had ongoing “Timing OVER ADVANCED”, warning issues since 2023. This is TOO MUCH for a New car!!! I’ve owned MANY cars and NEVER had this many issues!!! There appears to be multiple design flaws with this model and similar models!
