Assist problems of the 2017 GMC Acadia

The shift to park keeps showing up and I had this issue taken care of last year at the dealership and it just started again. It is over $600 to have the repair done and should last more than a year before it needs to be replaced again. The lane assist pops up every couple weeks that it is not working.

While driving get notice lane departure not working and thermostat registered zero, when code scanned, states low thermostat temp and able to reset with code reader. Will reoccur in minters to days later. This is an electrical issue to to the ability to reset with a code scan tool, but also a safety issue since it also effects the electrical safety ability associated with the sensor.

While driving at highway speeds, a warning appeared on the driver information center (dic): “steering assist is reduced – drive with care. ” simultaneously, the temperature gauge was stuck on “c,” the radiator cooling fan ran at high speed, and the air conditioning stopped blowing cold air. After researching the issue, I discovered that these symptoms are commonly linked to a failing thermostat—a known and widespread problem with gm’s 3. 6l lgx engine. Unfortunately, replacing the thermostat on this engine is not a simple repair, often requiring significant labor and cost. The most concerning aspect is the loss of steering assist, which poses a serious safety risk, especially at highway speeds. Given the frequency of this issue across many gm vehicles, it’s clear that this is a defective part and not an isolated incident. Gm should take responsibility and cover the cost of repairs for affected vehicles. This is not just a mechanical failure—it’s a safety hazard that deserves immediate attention. I'm attaching a picture of the message as well a paid repair invoice from the work the dealer performed to replace the thermostat on my vehicle.

It seems that all of these cars have a faulty side detection problem. Please check into it. It is a pain and is sad that it seems to happen to all of them. The side detection problem leads to other kinds of problems with the computers . . . The light stays on all the time.
