2011 GMC Terrain: sudden loss of power

Filed Jul 10, 2021 · Engine · PA

Timing chain either broke or jumped track while driving and car shut off while vehicle was in motion. Had to have it towed home and will not start ever since. I hear alot of complaint with this type of motor with oil use and timing with results of destroying engine completely and not having money to fix after paying alot of money for this vehicle. GM needs to take responsibility for their faulty 2.4l ecotec motor and issue a recall to those affected by this faulty engine. I was driving a busy street in my home town when the car just shut off while in motion. Lost all power to the vehicle and could have crashed or been hit or worse been seriously injured or fatally injured. Please take responsibility and fix the problems created by faulty equipment! I had purchased from used lot and broke down same month I bought it and has been sitting outside my house ever since over a year

Service stabilitrak pops up, engine goes into reduced power mode. Third time happening and dealership has done nothing to fix it besides charge me money. Car has 96k miles at this point and I’ve spent more money to fix it than it’s worth.

My 2011 gmc terrain while driving 45 miles down road the lose of power light came on and the car immediately slowed down causing me to almost have a accident. The car would run but shake real badly. I stopped the car and turned off for 5min and restarted and was able to make it home but had to do this at least 3 times getting there.I don't know what is going on, but I do know I almost lost my life in the process. My car seems to burn aiot of oil too here lately, like its drinking water.

I have been having an issue with the stability track/reduced engine power coming on. I will be driving and then the reduced engine power with an exclamation mark pops up, my car speed drops and then the car cuts off. The car would crank back up after sitting for a while. After researching this, I found that several other gmc, chevy and cadillacs had this same issue and were given the run around by gmc when trying to have it fixed. There was a recall for those vehicles but not the terrain. I have had the throttle body cleaned like suggested and that did not solve the problem. The problem occurs no matter if I am on the highway or regular streets. Being a single parent of 3 and legal guardian of 1 grandchild, I don't have money to keep trying to repair this issue. I had my transmission looked at and that was not the issue. How can I get them to correct the stability track/reduced engine power issue? I have been without my car for a week now. This is making it hard to get back and forth to work. I am actually calling the gmc headquarters to report this issue and then the better business bureau.

Abs light is on even after fixing the supposed problem. System stabilitrak constantly on. Excessive use of oil. 2 to 3 quartz every 2 weeks. Reduced engine power comes up on dash and no matter how fast I am going (15 MPH or 80 MPH on a highway) it doesnt matter my car will slow down or just shut off. Also happens when I have to hit braked hard, slow down or accelerate from a stopped position. I am also using a lot of gas.

We purchased a 2011 gmc terrain may 29th 2018 used with 70000 miles from the hazleton nissan from the hazleton auto mall here in pa. It now has 78000. Had two oil changes done already. There is definitely a excessive oil consumption problem with this vehicle as I just got a oil change hut the 50 percent oil life and having issues again. We have contacted hazleton nissan found out they were closing after signing a " set for life" contract which had a powertrain warranty. Now I cannot use my warranty.anyway I was driving home tonight from work on interstate 81 when the car without warning just cut off and lost all power. He got it to the side of the highway and had to put it in neutral and restart it. After it started he brought it to a gas station where it had stalled again. Got it almost home and stalled again. God forbid my children were in this car when this car decided to cut off and he had no brakes no steering nothing. Nissan in hazleton was aware of this and I can't even use my warranty that they signed and I signed. I was promised something that I cannot use. Gmc had a call from us around 73000 miles and I told them it was clicking and stalling. They wouldn't touch it bc nissan is the one who sold it to me and the contract was with them, but they are no longer open so what do I do now? I cannot afford a huge fix hence why I got this car bc the warranty and I wouldn't have to pay for anything if it fell under the powertrain which it is. If I needed a new motor I would get one for free see what I am saying? Someone could seriously get hurt or even die and this is our only vehicle can someone please help me? Kept up with all oil changes also. This is very dangerous and should be fixed. I fear for my wife and children as they always are using this car.

Fuel pump failure allowing gasoline into crankcase in large volumes. Rough idle, constant stalling, misfiring, fuel smell recirculating into cabin. Exact issue addressed by gm recall for my exact terrain and equivalent chevy equinox with 2.4 ecotec. Was told mine was not covered as it wasn't in correct VIN range though same make, model, year, motor, highly dangerous combustible issue matched. Dealer charged me $700+ for replacement/repair of fuel pump, both o2 sensors, fuel line, oil change to rid gas diluted oil. 2 days, 50 miles later, o2 code engine light comes on, erratic idling begins, power loss then stalls. Removed oil cap to smell and find gasoline mixed back into oil. Between 1/8 - 1/4 quart gasoline in the crankcase after 50 miles of driving! This after "repair" at "certified" chevy dealership; a dangerous manufacturing flaw gm acknowledged was a problem but I was told, " not on yours though, wrong VIN". Thank you for placing my loved ones in danger gm, refusing to fix your own recall, charging me over$700 to worsen the issue and place my family in greater danger.

I was driving on the highway and the car cut off as soon as I slowed down getting off the exit. I started the car back up and it said that the stabilitrack was off and that I was losing engine power. I got to safety, checked my fluids and I had no oil in the car. But I changed the oil recently and had 3,000 more miles till my next oil change. I towed the car to my mechanic and described what happened. He told me that their was an internal engine failure that caused the timing belt to break. I called my insurance and they had a field adjuster look at the vehicle and he nor the mechanic could figure out why or how this happened on such a well maintained vehicle. They both stated that there is no way that I should have had 2 major system failures (I just replaced the transmission) with the current vehicle mileage. I called gmc and they will not so anything to help me. Their only solution is for me to tow it to a gmc dealership and they will look at it. I could've died in this car, I still owe on this car and they won't help me.
