Recently reported FUEL/PROPULSION SYSTEM problems on 2015 GMC Terrain

I have a serious problem with my car the dealership to me my coil ignition has a crack in it and the is a lot carbon build up. i just bought the car in april of 2019 & i was told by car-fax the car had a 165 point inpection done on it

My vehicle is under 60k miles and one day i woke up went to drive it my engine light came on and my vehicle started to sputter and try to die out while driving in a school zone going 20 mph. then after making it to my destination i placed the vehicle in reverse and it died out on me. i started it right back up it died as soon as it hit reverse again. finally i was able to start it and coast backwards then place it in drive. i had recently gotten gas and thought maybe something was wrong with the gas but im seeing this is a problem for more people than just me. so disappointing bc it is a lease and my lease is up in one month so now im held liable to fix a problem that i feel like should be a recall. i've always stayed up on my oil changes, and maintenance and im very disappointed in the quality of this vehicle.

I have had my terrain for a little over two years now it only has 71,000 miles being a 2015 and it has started to stall out on me. the first time it happened i just got gas and thought maybe i didnt have my car in park. not even two weeks later it happened as i was parked at the grocery store and went to take off, it just stalled on me! it's happening more frequently and even just turned off on me as i was driving down the road. my check engine light is not on, we have even placed lucas in it to see if that would work.

The car keeps stalling when trying to accelerate in reverse or drive and the check engine light is on. this is problem as i am reading up on this so i believe there is some kind of recall that needs to happen. this is [xxx]. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

After coming to a stop and trying to move forward the vehicle stalled this happen several times and would also stalled when in reverse. there is only 47000 miles on the vehicle and is driven both highway and city. vehicle would only stalled after coming to a stop or driving under 5 mph. the check engine light is on and stays on for a few days then goes away. this has been happening since nov 22, 2018.

While driving in stop and go traffic my car stalled, after restarting it it continued to turn off after acceleration and shuddered when miles to 20 miles an hour.

Leaving my parking spot after going out to eat i went in reverse and the vehicle stalled at about 5mph, turned the car completely off and then turned back on. put it in drive and just as i started to accelerate it stalled. this happened 10-12 times while i was trying to leave the parking lot. vehicle stalled while leaving car wash as i was excelleratig our. vehicle stalled as i was leaving a complete stop from a stop sign on a city street. something is wrong with the engine stalling while starting to accelerate. 43,000 miles from first occurrence currently at 43,300 still happening on a regular basis.

On 1/10/18, i was on my way to work and received message "engine power reduced", the engine light came on and power was reduced to 25 mph. i brought the terrain into a mechanic and he synchronized the gas pedal sensor and fuel sensor and the engine light went out. on 1/13/18, the same thing happened except i was on a highway and it was much more frightening. i brought the terrain back to my mechanic and left the vehicle. i am now without a car for the weekend.

Started march of 2017 progressively getting worse. suv jerks, gauges go crazy, check engine light comes on, if slow to below 20 mph it sputters and won't accelerate, if i stop completely it won't accelerate. multiple times this has happened on the interstate during rush hour traffic & at busy intersections. if i turn car off and back on the system resets. then it starts all over again. it has been in and out of the shop. probably 10-15 times in 2years. they get codes, but then these go away before they can be 'run'. i broke down 1-1/2 weeks ago in bay minette & the car wouldnt start back up. i was stranded out of town and had to rent a car to get back home. the dealer there got 7 error codes that all cleared out. i have filed a compjaint with gmc, but they are slow to handle the problem & i can't get supervisors on the phone or at least one who doesn't seem like he's been drinking.

While switching lanes in traffic ( around 15 mph), the vehicle shut off (including radio gauges and engine). put on hazards, switched from drive to park, and restarted the car. *tr
