It began with showing "Service Brake Assist" for about 2 weeks + then on Dec 18th 2023 around 10:30 as my fiancé was stopped at a stoplight and all of sudden when the light turned green she attempted to continue forward as traffic started to move only to stall stalled out before any movement could be achieve the battery was reading severely depleted and the vehicle would not function at all she was stuck in Drive and could not put the vehicle in neutral or even park to even try to restart the vehicle, she could not even turn the steering wheel, roll down the windows, open the door, or anything. the only thing she was able to accomplish was opening the hood so an officer that had arrived at this time could give her a jump, The officer also proceeded to leave the negative cable on the battery terminal and disconnected the Positive cable from the battery terminal which would have indicated a bad starter or depleted battery when the positive cable had been removed, which was not the case. she continued to where her appointment was and that is where i met her and took over vehicle to transport it home, driving with hazards on. I arrived at the house with no incident. then at 4:45pm on the evening of 12/18/2023 while at the stoplight I had a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum where the vehicle wanted to stall out while i was stopped at a stoplight attempting to proceed forward. and then at around 10:20 pm while stopped at a stop sign a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum attempting to proceed forward. On Dec 19th 2023 around 10:00 am I test started the car by remote and it started up and then i turned it off, now it is showing that the battery is completely depleted at 1:26 pm

I was driving my car December 10, 2023 when I was at a red light my truck completely shut down I could not reverse I could not put in drive I could not put in Park I could not switch gears. I didn’t know what happened. I had to call a tow truck to get me home once I got home I got my car towed to a shop. Before my car was towed I contacted OnStar. OnStar did a diagnosis on my car and it came back ECM which stands for electric control module. When my car was at the shop i got a tune up & the mechanic was able to start my car. Driving again on the date of December 15, 2023 it did it again and it said ECM. I was paranoid because I was on the expressway I had too get my car towed to the Dealership. This is the second time that my car has did this. I keep all maintenance up on my car. I’m not understanding what’s going on. I feel like it should be a recall on this issue. It was very dangerous both times that my car stopped. Now yet again I’m waiting to see what the problem is. This is definitely a safety recall issue. I have a 2018 Denali terrain with only 71,000 miles i keep up with oil changes and maintenance on my vehicle. Who do i contact about this concerning scary situation, Will it take for a person to die before this is is rectified. Someone please contact me or respond to this situation. So we can request for a recall on this serious matter

On Wed., Dec. 6 around 3:15 pm during heavy traffic on FWY [XXX], cars slowed down to a brief complete stop. When I went to start slowly as traffic began to move, engine completely shut down. I could not open windows or my door to get out of vehicle. Immediately called 911 and was transferred to DPS. It took approximately 65 minutes before I had help and was finally towed from the dangerous freeway lane where I was stuck and with vehicle completely stalled and locked down, I couldn't even get car in N to be able to have help moving to a non dangerous place outside of the FWY lanes. This is the fifth time this car locks down. I've learned to open a panel by the foot brake area, pull a lever in that area and be able to move the car to a safe location until I got towed into the dealer. It is the second time that this has happened in a potentially dangerous street and now Freeway. Danger to myself and many others that had to maneuver around me. The first time (around 2020) the car totally shut down, it was reported that a computer harness had to be replaced. This last time I was faced with such a dangerous situation on a FWY it was determined that the ECM (Engine Control Module) had caused the shutdown and locked the vehicle to where I could not even get out for close to an hour. The ECM was replaced by GM and the car is running again, but my shock and trauma still haunt me as to the self and others danger that was present. . GMC Dealer finally determined after several attempts that ECM was the problem. Unsure if available to inspect it. Delivered car back 12/8. . Heavy freeway traffic at peak hour put me and many others in serious danger. . My dealer report reads it was difficult to diagnose and finally find ECM was the problem. .Vehicle has not been inspected by Manufacturer, police, or insurance. .A few minutes before this lock-down an engine icon appeared while on the FWY. Previous shutdown incidents had no warnings or messages before locking up. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFO

The 2018 GMC Terrain has the AutoStop feature but does not incorporate a switch to defeat AutoStop. In heavy stop and go traffic or when fast acceleration from stop is required, the response of the engine in having to restart creates not only a nuisance condition but a severe accident hazard. It not only hesitates from stopped, it lurches forward after hesitating, which could cause a collision with a vehicle in front. I have had several other vehicles equipped with AutoStop, and all of them have a defeat or cancel AutoStop switch to allow the operator the opportunity to turn AutoStop Off. My 2018 Terrain Denali is now on its third battery. Having a dead battery in traffic also constitutes a safety hazard as does the inherent danger of using jumper cables. I have asked my dealer for a way to defeat the faulty feature, but they either cannot or will not do it. There must be a software code to easily allow this that the dealer can perform or a slight hardware modification to allow the operator to defeat AutoStop when it creates a safety hazard.

Driving 2,5 hrs from Binghamton, NY towards Long Island on Saturday. We took a short break and after that I got onto the highway and not even hit the 50 miles/hour speed I received “engine power reduce” alert on the dashboard and car stalled. I was able to pull the car off the road. I was provided a tow truck by the state police and moved to closest GMC service, GRAND PRİZE GMC Nanuet, NY. This car has only 30,309 miles and it’s 2018. The car has been fixed by replacing 5 parts, oxygen sensor, pcv tube, air inlet tube etc. We ended up paying $1,460 just before the Holidays. Rightfully, we are very upset with this unexpected event driving a basically brand new car, in 30000 miles. This car has been mostly driven by my wife who is in 60s in local streets not exposed to harsh enviroments. There is a recall I noticed online for 2019 models and almost from the same area of throttle body, but nothing for 2018. Now, my wife and I hesitating to drive the car. Are we going to get stuck on the road again?

There is an has been an issue with my electrical system says I purchased this car in 2017. Myself believe that the issues have not been documented until 2020. When my racy begins to run out, my engine light has been coming on and I’ve been getting the same code P1101 I took my vehicle to GMC and they told me that the engine light came on because the tape came loose. I brought this vehicle and there’s no way there should be no tape on it. The service tech also told me that if the problem continue to bring it back and I will have to pay $120 or whatever the label rate was for them to research I contacted GMC to file a complaint and I received the whole bunch of calls from a guy named Kevin. I believe he told me that he had been contacting [XXX] and no one returned his call and that he was sorry he couldn’t help me. This is my report number one of them from GMC. [XXX]. Everywhere I take my car they tell me that they have a lot of customers with the same issue and they tried to replace what the code is matching which is the mass airflow sensor but that does not help there is some type of problem with the engine or the electrical system with this vehicle. I am not the only consumer that has had this problem. I don’t know what to do. I have two kids I cannot afford to keep pay and label rate for them not to find the problem. I am also attaching the typical email that GMC sent out when they are working with the dealerships because I have been in contact with them and the person that was calling and then they sent me this email.

While driving down the road at approximately 55 mph, came up to an intersection, 4 Lane I was in the right lane to go straight, there was a right turn lane next to me. I applied the brakes, pedal was really stiff and very slow to respond, I was able to edge over into the turn lane cutting people off and just barely missing the vehicles in front of me. It took 5 car lengths to stop my vehicle. When I finally was able to get the vehicle fully stopped I was almost in the paths of the crossing traffic.. when the light turned green I was able to slowly cross the intersection looking for a safe place to pull over. Immediately crossing the intersection the Service Brake Assist notification appeared, about another half mile the vehicle informed me of loss of power and that it was reducing engine power (limp mode). I was able to find a gas station parking lot to put it. When I opened the hood I noticed quite a bit of engine oil located under where the brake assist pump was located. I had lost about 1.5 quarts of oil. I refilled that. The next day I returned with a tow dolly. The vehicle was started just long enough to load and unload it at home. We pulled the vacuum pump where upon inspection it was noticed that the part has exploded and so far we are still missing some pieces that may be inside the engine. This is a known and documented problem of this part and should have a safety recall issued. . I still owe over twenty eight thousand on this vehicle and it has only 109,000 miles on it. I hope we can find all the pieces and that the engine wasn't fately harmed. GMC needs to make this right, a lot of people could have been harmed.

For the third time, the brake booster has failed on our GMC Terrain. We had the first replaced with an OEM part. That booster failed after 2 weeks. A second OEM brake booster was installed. That one lasted about a year until it failed as well. This time we were traveling down the interstate and interstate speeds. There were no indications of an issue until trying to slow down when attempting to exit the interstate. Luckily it was a long ramp and there was not much traffic as I had to push extremely hard to slow down the vehicle. Knowing immediately what had happened, we noticed a GMC dealership was just down the road and safely made it. We left the vehicle at the dealership and rented a car to continue our vacation. We are now being told that not only did the brake booster fail, but the components entered the engine and caused major damage. The suggested repair is a full engine replacement. This is unacceptable for an issue that GMC has know about and has had recalls for on other years of their vehicles. Not only could my family have been severely injured, or worse, we are not financially able to repair the vehicle.

I have a 2016 GMC Terrain, garage kept and seldom driven, with ONLY 53,260 miles on it. Last night while leaving the movie Theatre in the RAIN my WIPERS stopped working while in motion. I had to drive home in the rain unable to see!!! Looked on NHTSA.gov site and saw where recalls were issued for 2015’s but not 2016’s, although I’m reading numerous complaints for the same occurring on my model suv. Can GMC provide some insight into this?

When turning right or left from a stop, the steering wheel jerks sharply in the opposite direction as soon as the car starts to accelerate. Diagnostic tests and inspection determined that the steering gear is loosing voltage causing the jerk in the steering wheel. The gear has the latest calibration and needs to be replaced. Cost estimate to replace is $2035.63
