Over the past couple years I have become worried to even drive this vehicle. Well Taken care of and maintenance completed regularly. This vehicle has been in the shop 7 times in the past couple years but no one can tell me exactly what is going on. Only 1 place has told me that I need extensive electrical work but couldn't tell me what exactly the problem was. Issue #1: When coming to a stop, and/or idle, the engine seems to give up and vehicle shuts off. Issue #2: When started Engine sounds like a.high pitch raddle. Issue #3: Occasionally, while driving on the interstate going around 60 - 65 mph the electrical inside the vehicle will flash and everything shuts off and the emergency brake is applied automatically. This has become dangerous - if I wasn't wearing a seatbelt I could have been thrown through the windshield. Issue #4: Replace Fuel Cap Sensor comes on even though it's been replaced. Issue #5: Engine Power Reduced notification comes on even though it had a new battery and alternator. Issue #6: Occasionally Speakers sound blown and you can hear a buzzing as you accelerate. Issue #7: Stabili Track, ABS, and TPMS Sensors all come on at once and go away at once atleast 4 times a week. Issue #7: Rear Cam doesn't always work, sometime either black or static looking. Issue #8: Sometimes key sticks in ignitiin and will not turn on unless being jumped by another vehicle. Issue #9: Often upon starting the whole dash goes black and will stay that way for several hours then comes back on. I've checked all fuses and multiple mechanics can't figure it out. As time goes by without repair I'm scared to even drive this vehicle. Why can't someone figure this out!!

Takata recall my car has been throwing a engine power reduced and service stabil trak light. I have had it in the shop five times now, after replacing a coolant sensor which is a code it through, it has thrown three pedal sensors, after replacing it the first time the mechanic place told me the pedal was bad, sent it back replaced it again and the light came back on. This has been going on since the beginning of may and still not resolved. I have read several other people post about this on their terrains.

Several times in 3 years, the dealership can not duplicate the problem loss of power starts running slow, wont go over 20 MPH, check stability light comes on, check engine light starts blinking, acts like misfire or no fuel in vehicle, starts anywhere at any time, very unsafe and scary. At least taken to a certified dealership 7 or 8 times and every time they do something differant , yet the problem persists! The vehicle can be stationary at red light and big or while driving going 45 or 65 and drop to 20 MPH and not want to go, I push the gas paddle to floor and it does nothing. This has been intermediate and a problem since month 3 of buying my vehicle. This is not safe and the dealership has basically givin up on me and my vehicle.

My 2012 gmc terrain 2.4l is having an issue with excessive oil consumption. I am constantly having to check my oil and it gets to 1 qt or more low between my 5k oil changes. I've seen multiple complaints with this. Because of this I have a check engine light on indicating my catalytic converter may be bad. Ive had the car for about three years. It shouldn't need the catalytic converter already. My car is due for smog next month and I've akready had to repmace the intake and exhaust sensors on the engine because of the oil issue. This happens while car is in motion being driven. It is eating up oil.

I experiencing problems with my gmc terrain. I have contacted my local dealer (doral gmc, in miami, fl) on multiple occasions with no response. I have submitted a written complaint to gmc on april 10th, 2012 and never received a reply. I've experienced continuous car problems since the purchase of my vehicle. Within the first 3 months of purchase my car had already been kept at the dealer for 30 days on 2 separate occasions. Vehicle problems were, for example; the airbag service light turned on, car turned off while driving on a highway, this issue was taken care of but returned several times to have it corrected as it kept happening. The vehicle also experienced transmission issues, the check engine light also kept turning on and service department couldn't figure anything out with my vehicle.this was my first gmc purchase and it has been my absolute worst experience with any american car company. The latest issue since december of 2017 has been the airbag service light once again and the stability track light. I took the vehicle in for service once again and I was charged for diagnostic service so that the issue could be found for each issue and was told I would have to pay $135.00 per issue. I only paid for the airbag issue since it seemed to be the most dangerous one and was told by service department that the module kit needed to be replaced. This new charge was $ 823.90 that I had to pay out of pocket. This issue seems to be a factory one and I would like to be reimbursed since this is a safety feature that should not have happened. I've never had an accident and have kept it serviced and well maintained at the dealer through out all the recalls and service problems. The reason I paid for this service was mainly for the safety of my family but once again, it's an inconvenience.

While driving the vehicle, I experienced strong knocking vibrations and sounds seemingly coming through the floorboard. As I continued driving for about 5 miles trying to get home, the knocking became more pronounced and my steering was affected. I also began noticing an extremely strong odor necessitating lowering windows to breathe. I notified my dealership and took the vehicle in for diagnosis the very next morning without driving it after arriving to my garage. I was told the awd had completely deteriorated. My concern was that I never received any dashboard notification of the problem, not did my onstar diagnosis indicate a problem. I have been quite disturbed that the vehicle became disabled before I was aware of any problem. I have taken my vehicle in for regular maintenance at my gmc dealership and would like an explanation regarding the failure to identify this problem through the regular maintenance checks. I am single senior woman who has no backup vehicle and am quite concerned about my safety on the highway and this issue has caused me to have serious safety concerns. I drove the car to the dealership to check on the problem on friday, february 16, 2018. I called the gmc complaint center to check on possible recalls or any remaining warranties that might apply and I was told the center was assigning a sr. Advisor to contact the local gmc dealership that still has my car and the advisor was told the dealership needed more time to diagnose and assess the cause of the problem.I have had to rent a vehicle since it may be another 2-3 days before I even get a response regarding the nature and cost of the repairs. I was originally told the entire awd system had to be replaced at a cost of $1500--$2000. I questioned the reason for the extreme malfunction without any warning notices appearing...main reason for my complaint and concern.
