Thermometer stop properly working. Check engine light came on. Ran fhe diagnostic code which confirms the thermometer needs replaced. This began dec 2023 - bought the vehicle in oct 2023. Unsure if this was an issue prior. The cooling fan would kick on, and the temp gauge would stop working. Dealership was able to replace this and so far no further issues with the tempature reading.

  • Date complaint filed: Apr-17, 2024
  • Failed components: ELECTRICAL SYSTEM and ENGINE

Shift to park alert pops up when turning vehicle off. Vehicle is in park. This prohibits the vehicle from turning off. Per my investigation other GMC Acadias made in 2017 also have experienced this which results into either prohibiting them from turning their vehicle off or their battery dying. This is a safety hazard because it increases risk of being stranded due to malfunction.

Gmc of vacaville california sold me a 2019 gmc sierra that has a know back window leak issues. I was told by service worker gmc of vacaville california sold me a 2019 gmc sierra that has a know back window leak issues. I was told by service worker brent lewis/405 that is a common issue and gmc is aware of this issue that the vehicle was brought in before for this same issue prior from [xxx] but was not taken care of. I purchased this vehicle on [xxx] along with a 5k extend warranty that i was told is a bumper to bumper warranty. Come to find out it does not cover a manufacturer defected back window installation. My concern is that they are aware of these issues and water sitting on the inside of the cab due to a leak causes black mold and could cause serious illness to myself and my children.
