The thermostat is stuck open and needs replaced. If left as it is, could create overheating issues for the engine and even more damage. A service engine light was illuminated prior to finding the issue. The light was accompanied by a warning about assisted steering. Two days after the light first came on, a Chevrolet service department diagnosed the problem and is repairing it. An invoice can be provided at a later date once repairs are completed.

Nothing necessarily happened, but I've been getting the "steering assist reduced, drive with care" pop up, which assist I've been reading might mean a faulty thermostat. Sounds like a common issue and may e time for a recall? Only 60k miles on my blazer.

The affected tires were cured for too long during production.

Consequence & remedy

Consequence: Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.

Remedy: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.
