Oct 1, 2026Engine Steering assist warning comes on when I start the car and then the engine fan starts up very loudly and code PO128. My car has 48,000 miles and is a 2018. I am seeing this is a known issue and should be part of a recall so I want to know if itâs covered.
Oct 22, 2023 · 45,000 milesPower train The contact owns a 2018 GMC Acadia. The contact stated that after parking the vehicle inside the garage, shifting to park(P) and turning off the vehicle, the vehicle suddenly rolled backwards approximately 3 feet. The contact stated that the failure had occurred on several occasions and the vehicle only moved backwards. During one failure, the vehicle almost struck a pedestrian walking behind it. The vehicle was taken to the dealer on several occasions, but no fault codes were retrieved and the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 45,000.
Oct 30, 2025Electrical system I get error electric Steering assist reduced or unavailable drive with care at around 84234 miles on my car . Upon looking up problem on Internet it has to do with the Thermostat. I also found where Gm has a bulletin N252508350 which only seems to cover certain vehicles with the same problem. This seems to happen at all different miles driven on vehicles. I don't see how Gm can get away with only fixing certain vehicles with this safety problem when it shuts down the electric steering assist . This problem from what I can find on the internet is common to all years from 2017 up in Acadia with the 3.6L engine . The Thermostats seem to be defective and I feel Gm needs to address this problem…

The contact stated that while driving at an undisclosed speed, the power steering message was displayed, and the check engine warning light illuminated. In addition, the temperature gauge remained at zero. The dealer was contacted by phone and made aware of the failure. The vehicle was taken to the dealer, where it was diagnosed with a failed high-pressure fuel pump. The contact was informed that the high-pressure fuel pump needed to be replaced. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was contacted by phone and made aware of the failure. The contact was advised…
Sep 12, 2026Unknown or other Urgent code going off due to thermostat not being red gauge is stuck
Sep 10, 2026Engine The car will frequently but not always fail to shut off when the start/stop button is pushed while in Park. The message "shift to park" come up on the display and a yellow light comes on in the button. I have to restart the engine and it often takes as many as 10 attempts to finally shut off the engine. Between each attempt I have to shift the transmission out of park and back into park. This has been happening for more than a month.
Aug 29, 2026Unknown or other Iâm getting a shift to park on my dash after itâs already in park. This causes the break to get stuck when driving.
Aug 1, 2026Seat belts I am unknown of what the issue is with the seatbelts on all seats will not properly lock.
