ELECTRICAL SYSTEM, ENGINE
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.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
The car went into limp mode while I was on the highway. The car said reducing engine power and then I couldn't go the speed limit I had to drive well under the speed limit and pull off the road as soon as possible. I brought it home and water came pouring out the intercooler after looking online. I found out this is a known issue for this vehicle.

ENGINE, ELECTRICAL SYSTEM
GMC Terrain with 12,564 total miles had experienced an engine failure. Under normal driving conditions, the car was sluggish and would not accelerate properly when pulling out into traffic or when getting on the freeway/interstate causing fear for driver safety and causing traffic slowdowns or congestion with a significantly increased risk of crash. While driving to work, the vehicle service engine light turned on and displayed "reduced engine power". Upon investigation the dealership found codes P0011, P0014, P0016, P0017, and quoted "Cylinder 4 intake rocker had fallen off and laying on head, found excessive debris and metal material around rocker 4, Found cylinder 2 intake rocker to be worn sideways. Found heavy damage to intake camshaft. Removed oil filter - found excessive metal in oil filter". Secondary issue, infotainment screen would randomly flash bright white on the right half, causing a major driver distraction. Engine, turbo, and infotainment system were all replaced, and vehicle returned 11.06.2025

FUEL/PROPULSION SYSTEM
My wife was driving down the road and all of a sudden the car just shut off and wouldn’t start back up. She called me and I went to her and tried to get the started with no progress so I called a tow truck to come pick it up and come to the mechanic shop to have it fixed. They run a diagnostic test on it and it was the fuel module. Called the gmc in my town and the said it was not covered under warranty or there wasn’t a recall on it either. W needed my car fixed so I called around to find a fuel module and finally found one in north Myrtle Beach. I had to go and pick it up around 75 miles from where I live and bought it back to the mechanic. He put in on and that fixed the problem. A lot of the 22 Terrian’s has a recall but mine doesn’t. I would like to know why mine doesn’t and it only has 53,000 miles and mine falls in the same category as all the others. I think I should be reimbursed having to pay to have mine repaired.

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
The car was at a red light so it automatically stopped. when the lights turned green, I removed my foot from the break and the car would not move. I had to call OnStar for roadside assistance and they called the police to make sure I was safe and that traffic flowed safely. My car was towed to the dealership after they tried to start the car by the key and my jumper cables. The car would not start. The dealership is unable to start the car as well and they are saying that the issue with the fuel pump is not under the most recent recall for my VIN number. I was able to locate the recall for the same exact issue that I’m having under my VIN number on the GMC website. I have filed a report with the GMC manufacturer to try and get this issue fixed. I have brought this car in multiple times to the dealership I purchased from and an additional dealership to show them the issues that I have been having with this car starting and stopping, I could have been ran over by a public transportation bus today.

I ONLY AM ARGUING BECUASE THIS WAS A RECALLED ITEM THAT HASNT LASTED VERY LONG.

FUEL/PROPULSION SYSTEM
My GMC Terrain started, but then stalled as I tried to pull away from the curb & drive. When I tried to restart it, it turned over but would not start. My AAA Autoclub servicemember used his "check engine" interface machine to determine that the fuel pump module was not communicating with the car, though there was half a tank of gas. This issue has been a well published problem with this year, make & model online, but GMC is not including my VIN# in the recall. I had the car towed to my mechanic & his diagnostic tests revealed the same problem - fuel system module. I would have been in danger if there had been any traffic on my residential street. If the car had driven a few blocks & then stalled, I would have been on a busy boulevard. There were no warning signs prior to the stall. There is a "check engine" icon lit up now because it is going to require service. My mechanic can't fix it, so I need to arrange another tow to get it to a dealership service department. Thank you

FUEL/PROPULSION SYSTEM
I went to start my vehicle up my two days ago (8-25-25) It made a horrible sound and just shut off. The lights on the dashboard would not go out when I turn it off. I also couldn't put in gear. It had to be towed using a dollie to the repair shop. I was told that the module fuel pump power control had to be replaced. The shop owner then went on to tell me that this very same brand (GMC), has been entering his shop at a shockingly alarming rate with this same problem. I'm not very pleased with having to have this repair done as my vehicle is no longer under warranty. It cost me $432.18. I'm not rich and am living in a time as many others are that don't have a bunch a money laying around to throw away. I find this very distressing as well as unfair to my family and I to have to have this replaced on a relatively newer vehicle. If you are aware of this problem, it out to be addressed. I as well as others should have been made aware as well. At the least, I think that I am entitled to a refund for the cost of the repairs.
