The vehicle’s power steering and stability control (Stabilitrak) have stopped working suddenly several times over the past two weeks. There have been no warnings leading up to the loss of power steering .This has happened while I have been traveling at highway speeds as well as in the middle of making a turn and has nearly led to crashes on a couple of occasions. It has also happened at lower speeds as well as upon starting the vehicle with no rhyme or reason. The vehicle has not been inspected for this issue but is available for inspection if necessary. I understand that this same issue has also led to a recall on the previous year’s model (2015 GMC Canyon).

With only 89K miles on my vehicle I’m having to replace 13K dollars worth of parts due to a known issue with the 5.3L V8 engine with the AFM DOD system that GM hasn’t fixed and refuses to help cover the cost cause I’m outside my warranty. I feel they need to extend the warranty miles and time frame due to the common occurrence of this issue

Vehicle refuses to turn off due to "Shift to Park" error being displayed. Vehicle also gives "Driver assist unabled. Drive safely" message and AC will not cool and vehicle coolant gauges will not work.

The car stopped working all of a sudden, I was driving the car with no issues that morning and parked & shut off car to go to my appt. I turned the car back on and worked fine as I was putting in my address on the GPS my car just stopped and shut off by itself. I pushed the start button and it sounded like it wanted to start but it wouldn't and the whole engine shooked. Called GM and car still under warranty had it towed to the nearest GM. They diagnosed it and said it was the fuel injector module that went bad. It's 2021 with only 23800 miles. After a week, just got it back for a day and now the cooling fan has a loud noise, check engine light on, coolant stays on C even after driving it more than 10 mins, ac blows hot air, I get an alert with steering assist is reduced and to drive with care.....seems like something is wrong with the thermostat.
