I have had my check engine light come on for P0299. I've lost power while on the road. Had my turbo replaced and now the same issue is starting again. I'm afraid of my car stalling out again with my child in the car. This is a definite safety issue especially since this is happening again months after getting the new turbo put in.

What owners say
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 the federal safety agency investigate the loss of propulsion and whether the campaign’s coverage should include my vehicle.

Vehicle Information:Year/Make/Model: 2021 GMC TerrainEngine Type: 1.5L Turbocharged EngineCurrent Mileage: 155,000 miles [1]Description of Safety Defect:I am writing to report a severe, sudden engine and turbocharger failure on my 2021 GMC Terrain that presents an extreme, life-threatening safety hazard. While operating the vehicle in active traffic, the engine began flashing a severe dashboard warning reading "Stop Now Danger" (accompanied by low oil pressure alerts) before suffering an immediate, catastrophic loss of all motive power. 2-This unexpected stalling leaves the driver completely stranded on active roadways without warning, drastically expanding the risk of a high-speed rear-end collision. A mechanic has inspected the vehicle and confirmed that both the engine assembly and the turbocharger require full replacement, with a repair estimate totaling $12,000. General Motors is currently facing legal actions regarding defective, camshaft-driven mechanical vacuum pumps and PCV configurations on these 2018–2022 1.5L engines defects known to fracture, send metal fragments violently into the engine top, and trigger immediate engine failure and turbocharger destruction. Despite these severe risks, GMC has refused to provide any goodwill assistance or repairs because the vehicle is outside warranty. I request that the federal safety agency immediately investigate the engine-destroying defects inherent to the 2018–2022 GMC Terrain line to protect consumers from catastrophic highway power failure.
Avis Rental. Vehicle simply shut down while driving and would not re-start. Vehicle could NOT be put into neutral to move from roadway. Emergency services vehicles had to remain on site awaiting tow vehicle. Very dangerous situation.
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 stalled and did not want to start. It had to be towed to the nearest GMC dealership. my GMC dealer diagnosed a P129F fuel-pump control-module failure and replaced fuel-pump power control module part number 13554821. I was told that even though there was a recall for 2022 GMC Terrains for this part my VIN number was not included.

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.

The car suffered a long crank, then stalled completely while moving on a public road, which is a severe safety hazard.
While driving home from work my 2020 GMC Terrain stalled and turned off. I was on a very busy 2 lane road, crossing a intersection in a tourist area in [XXX]. This could have be come fatal very easily. I was able to get the car started and Home but had to take it very slow. Next day we weren't able to get the car started nor turned on. Battery is new and still works, we also had a mechanic come to the house and run his computer telling us it was the Fuel Pump Control Module. There were no warning signs leading up to this moment. I see there has been recalls for the same issue for 2021 and 2022 models but my GMC dealership I bought my car at is telling this isn't an issue in any Terrain that they are aware of.
