EXTERIOR LIGHTING
I have had 3 taillights replaced. The first one was the driver's side taillight at Marty's GMC in Kingston MA. The second one was the passenger side taillight at Quirk GMC in Braintree, MA and the third one was the driver's side one again. the vehicle had approximately 28,000 miles when the 3rd taillight was replaced and was purchased in August of 2024. Both dealers stated that it was safe to drive the vehicle with the taillights not operating. The first 2 took approximately one week to get the part and the 3rd one took 4 weeks. I believe that this is a serious safety issue as the vehicle tailgate lights are only visible when directly behind the vehicle.

FORWARD COLLISION AVOIDANCE: WARNINGS
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.

ENGINE
Check Engine Light came on with message of "Steering Assist is Reduced Drive with Care". This same thing happened to my sister-in-laws 2019 Acadia 2 months earlier. Took it in right away to the dealership to find out it's the thermostat, it's a common/known issue and it isn't covered under my extended warranty and will cost ~$1300. I'm seeing this is a common issue for Acadia's and has not had a recall, don't understand why. It's one thing if this is a easy part to replace, but GM has made it so that most people now need a dealership or auto repair shop to fix it.

ELECTRICAL SYSTEM, LANE DEPARTURE: ASSIST
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.

STEERING
The steering assist message comes on and off whenever the weather gets cold in the fall and winter. This causes my air conditioning and/or heater to not work. I have done research and the temperature sensor needs to get replaced because there is a malfunction of the temperature not reading the coolant. Everything is fine with fluids and driving. This happened when I turned on the heater.
