2022 GMC Terrain

My 2022 GMC Terrain lost power and stalled while I was driving, creating a safety risk because I could no longer maintain speed in traffic. The incident involved a police response and a safety-related tow costing $250. On XXX, OnStar recorded diagnostic trouble code P129F. Tire Choice subsequently replaced the fuel pump control component, identified in my records as GM part number 13554821, at a repair cost of $493.25. I have supporting diagnostic, repair, towing, and police documentation, along with evidence of the removed part. GM’s later vehicle history printout showed zero open field actions for my VIN [XXX]. I am concerned that this failure may be related to the fuel pump power control module condition described in GM campaign N252516900, although I have not confirmed that connection. I request that NHTSA investigate the loss of propulsion and whether the campaign’s coverage should include my vehicle.

The vehicle experienced a complete loss of infotainment/audio functions immediately following a GM over-the-air software update. The OnStar indicator turned red, all vehicle audio including turn-signal sounds stopped functioning, and the rear backup camera stopped displaying an image. The backup camera failure creates a safety concern because it eliminates a federally required rear visibility safety feature. GM has advised me that software updates do not cause these problems and instead reveal an underlying issue. However, GM Preliminary Information bulletin PIT5971B identifies a software anomaly associated with loss of audio and a red OnStar LED on affected GMC Terrain vehicles, which closely matches two of my symptoms. I am concerned that a software-related defect may be causing or contributing to the simultaneous loss of multiple vehicle functions, including the backup camera. The loss of the backup camera is a significant safety concern because it prevents me from seeing the area directly behind the vehicle when reversing. The simultaneous loss of multiple functions occurred immediately after the GM software update and has persisted despite completing the recommended reset/troubleshooting procedures. GM is currently requiring me to pay for diagnosis despite the failure occurring immediately after the OTA update. I am requesting that NHTSA document and investigate this potential safety-related software defect. GMC Customer Service case 107120047

I am filing a safety complaint regarding my 2022 GMC Terrain after experiencing a sudden infotainment system failure that also disabled my backup camera functionality. The infotainment screen in my vehicle suddenly went completely black without warning and without any physical damage to the vehicle. The screen failure caused the backup camera to stop functioning as well, creating a significant safety concern while reversing and parking. The vehicle currently has approximately 50,000 miles. When I contacted the GMC dealership regarding the issue, I was informed that this is a common problem with GMC Terrains. However, because my factory warranty expired only weeks before the failure occurred, GMC declined to provide any financial assistance or goodwill repair coverage despite acknowledging the issue is commonly seen. This defect directly impacts federally required rear visibility safety equipment and creates unnecessary risk to drivers, passengers, pedestrians, and surrounding vehicles. Backup cameras are an essential safety feature, and the sudden failure of the infotainment system removes access to that safety function entirely. I believe this may be a widespread defect involving the infotainment and electrical systems in the 2022 GMC Terrain and request that NHTSA investigate this issue further for potential recall or manufacturer accountability.

When driving vehicle, alert sounded lowered speed detection and my engine light came on. My vehicle then lagged power and it smelled like something was burning. Called dealer i bought vehicle from and i drove it in to them. I just bought the vehicle 8 months ago. I was just in to same dealer for a GPS tracker that was in my vehicle unknown to me that the Onstar stopped working and the dealer had stating they missed it in the pre certified inspection and they had to replace the telemax module do to the unknown GPS Tracker. My vehicle is now in for the lowered speed detection problem which my GM app stated it was an air induction system problem. I do not have paper work for the air induction system yet but i have sent photo of what my GM app produced.
