Takata recall : sucking up oil, rattling sound, car jerking forward- diagnosis from GMC dealership- replace pistons, timing rings, and actuators, vehicle had 1 quart of oil and vehicle had regular oil checks and was in shop less than a year prior. This was a known recall by the dealership. 59k mileage on vehicle . We have letter and all documents

I was driving on a city street and the stabilitrac words came up on my dash. Then it said powering down. Then my vehicle started running rough and I pulled over and shut it off. I waited a minute and shut off traction control button. Then started again and a few minutes later the words came on again and it started running rough. I shut it off again and waited and got it home slowly about 3 miles.

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"

There was a recall for my vehicle to replace the high pressure fuel pump. This was replaced and 1 week later the check engine light came on. Taken to dealer. Diagnosed as catalytic converter. The catalytic converter is under a public service extended warranty (10 years, 120,000 miles whichever comes first). Of course I now have 138,000 mile on the vehicle. GMC will not cover repair costs. This should be a recall not an extended service warranty. The vehicle was moving when the light came on. I first called about replacing the catalytic converter when notified by mail of the extended service warranty, and because the mileage was over 120,000 miles and the light was not on, I was told there was no reason to have it repaired. Depending on what is causing the catalytic converter diagnostic t

Significant exhaust fumes accumulating inside passenger cabin during idle/stop. Volume of gases smell less while in motion but still evident. Significant reduction in engine power noticable; as well as erratic noise from the engine and extemely hesitant acceleration response.

Several times over the last week my car is stalling. It happens if I am at a stoplight, don't get up to speed fast enough, etc. The m as malfunction indicator lamp keeps going on and off. There are several complaints of similar issues and this should be handled by GMC. *tr

Engine had to be replaced at 84,000 miles . States on docs at time of replacement timing chain and cam worn due to low oil .has warranty but for replacing due to 'oil consumption ' but service manager refuses to write that although he has stated it.gm refuses to help

Shoulder bolt that controls height adjustment on power driver's seat. I have asked on two different occasions and always no parts available. Do not allow wife to drive vehicle as there is significant difference in our heights. *js

Driving home from work and making a right hand turn the car started making a horrible grinding noise. I thought my wheel was coming detached from the car. Had the car towed and have been told that my front differential "exploded". Not a happy camper, bought 2nd hand, has 77,000 miles now costing me 2500.00 to 5000.00 to repair. Sad thing is, is we never use the 4 wheel drive.

On 08/05/2020 I was sold this vehicle with a cracked manifold. Upon replacement of the manifold it was discovered that two manifold bolts were seared on the engine block side. After consulting my mechanic and another, I was advised that 1) to repair the engine has to be lifted as the space between the firewall and the engine is too small to make repairs without lifting the engine ( manufacture defect) . Further, it was advised to me that completely sealing the manifold could lead to a fire in the catalytic converter because ' these engines run hot'. As I expressed that this vehicles 'antifreeze' level is not stable as I have experienced with other vehicles. In other words this vehicle burns up antifreeze quicker than I've seen occur in other vehicles. After researching the topic it was dis

Going to visit son, daughter in law and grandaughter in virginia from michigan. Got reduced power message with stability control light. First time was without warning on the curvy hilly pennsylvania turnpike in traffic at appx 70 MPH.. Lost power on hill had no acceleration, vehicle decelerated in front of traffic. Put on hazards and worked our way over to shoulder across 2 lanes of traffic. Thank god this didn't cause a pileup of holiday travelers. Stopped vehicle, engine was misfiring, there was no throttle response. Shut off engine and restarted, power was back but check engine light is on. Continued trip, 2nd incident was about 1 hour later also without warning. Had about 5 incidents this trip.

I smelled fumes. The check engine light did not go on. I brought to my mechanic who said it had a cracked exhaust manifold. Co is leaking into my car. I will pay $1000 to have this fixed. No accidents. Just a faint smell of gas. I have 2 kids and routinely bring other peoples' kids into my car. Unacceptable GMC.

While driving wipers stopped working, was told I needed and new wiper transmission. This was extremely hazardous because it was raining heavily. The mileage on the vehicle was approximately 94000. *tr

While traveling on interstate 376 west out of down town pittsburgh, pa during rush hour the service stabilitrack warning message appeared and then the reduced engine power warning came on. At the time we were traveling about 45 MPH and the engine would not go any faster than 20 MPH when we got the messages, we had to try to get over to the side of the road.... We turned off the vehicle and waited 10 minutes and it reset itself... It happened 3 more times on monday 12/22 and the last time I could barely turn the steering wheel.. It turned out to be the throttle body needing replaced. *tr

I bought my 2011 AWD 4 cyl. Terrain in july, 2011. I traded my GMC acadia in on this vehicle. I down sized to get better gas mileage. It stated that it should get 20 city & 30 hwy. I have never came close. I took it to the dealer and they said it is running fine. MPG at 22. I don't know what we all have to do to get gm to do something about this but something needs to be done.they have pretty much lied to all of us and anyone that is thinking about buying one. We need to get the word out about this vehicle. Don't buy it for the gas mileage because it don't get what it states!!!!!!!!!!!!!!! I think gm should do something about this or reimburse us for the difference that we would get with the correct gas mileage. Maybe this will get a recall on these vehicles. *tr

On 11-21-10 my five year old son bumped his head on a hard surface that was not safely designed or padded properly. This happens when the brakes are applied strongly. Nothing was done by gm to correct this issue. *tr
