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.

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.

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.

My check engine light came on and I got it hooked up to get the code of P0171 - Upon checking it was different things like O2 sensor the Mass Airflow sensor, fuel pump issue etc. I have been having issues with slight hesitation during acceleration, some jerking when slowing down (not hitting the brakes). Now the check engine light was on for one day the next day it was off. I did some research and found an article that stated that GM is issuing a safety recall for 2021 and 2022 GMC terrain due to a problem with the fuel pump module failing, not enough fuel to the engine and creating stalling risk. This was from January of 2023. It also said GM notified the National Highway Traffic Safety Administration of the upcoming recall on Jan 19th 2023 and was still pending as of Feb 2023. Also stated that GM has not yet conducted actual repairs to correct the issue. My truck, I bought it brand new on Jan 20th 2022, only 23,450 miles on it. The problem literally came out of no where a week ago. The hesitation, not being able to accelerate is very dangerous when I'm on the road, I could not get the check engine light checked out professionally because the next day it was off and I was informed that they could not do a proper diagnostic if there is no light on. Obviously there is an issue with the fuel system and I really want this checked out and possibly replaced. Not to mention my gas is also going very fast now.
