2022 GMC TERRAIN Complaints

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

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 wouldn’t start in my driveway.. onstar sent me an email with code P129F ( fuel pump driver control module) failed. I am thankful I wasn’t 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.

Read • 9:59 PM I am formally requesting a VIN eligibility review under GM Customer Assistance Case #XXX. Vehicle: 2022 GMC Terrain VIN: [XXX] DTC: P129F Recall: N252516900 – Fuel Pump Power Control Module I was advised that my VIN is “not included” in the recall. I am requesting that GM reconsider and formally document the basis for that determination. GM’s XXX revision of N252516900-01 states that the phased launch was complete and that all VINs had been placed in an Open status in GM’s Investigate Vehicle History (IVH) system. The bulletin specifically identifies the 2022 GMC Terrain as an affected model. Additionally, GM previously issued engineering information specifically concerning 2022 GMC Terrain vehicles experiencing DTC P129F, including situations involving failure to start and/or stalling. Because my vehicle experienced P129F, I am requesting: A formal VIN eligibility review for N252516900. Confirmation of what GM’s IVH system shows for VIN [XXX]. A written explanation of why my VIN is excluded if GM determines it is not eligible. Documentation of my P129F failure under Case #XXX. Review of whether my vehicle’s failure is consistent with the condition addressed by N252516900. Review of reimbursement eligibility for any qualifying repairs or expenses associated with this failure. Please do not close Case #XXX until this VIN-specific review has been completed and the basis for GM’s determination has been provided. I am requesting that this matter be escalated to the appropriate GM technical/recall authority if Customer Assistance cannot resolve the VIN eligibility issue. Thank you.
