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. GMâs 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…

The car just stopped accelerating and the check engine light came on. I took it to a shop and they had to replace the fuel pump control module. There is already recall for SOME 2022 GMC terrains but my vehicle is not included in the recall. I dont understand how a 2022 GMC terrain has a recall for the fuel pump module but my 2022 GMC terrain is not part of the recall already put out and I have the same exact issue as the other vehicles that had been recalled.

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…

The car stalled while traveling down a road. We tried to restart and it would run for a few seconds and stall. We could not restart. There were no warning lights before the stall and after the engine would not run to get any other indicators that something was wrong. Had it towed to dealership, their diagnostic's showed it was a fuel pump driver module. Upon researching the issue, there is a recall for this problem but my VIN was not included in the recall.

My car wouldnât start in my driveway.. onstar sent me an email with code P129F ( fuel pump driver control module) failed. I am thankful I wasnât driving down the highway when it went out. My husband took it to Lexington Park Chevrolet Buick GMC dealership, where we bought the car and they replaced the part. My car only has 41,898 miles. My VIN #: [XXX] , a 2022 GMC Terrain Denali. I noticed online that other 2022 GMC Terrain has a recall on this part, but not my VIN #. I feel my vehicle should also be part of this recall.

I was told that even though there was a recall for 2022 GMC Terrains for this part my VIN number was not included.
