2012 GMC TERRAIN Complaints

I was getting on the Interstate when a really bad rain storm came up. I turned my windshield wipers on and they got stuck in the upright position. I tried many times to get the wipers to work, but they would not move. I had NO VISIBILITY and I was on an elevated ramp getting on the interstate. I could not see anything so I had to roll my window down, drive 5 miles an hour and use the white line on the road as a guide. I got soaking wet as did my car. I had to drive about a mile before I could safely stop the car. There was no warning and I am reading now there is an issue with this on Terrains. This was an EXTREMELY dangerous, I could have severely hurt myself or someone else. I am getting really tired of all the recalls on the Terrain. So far there have been six (6) for my car and a few more that don't seem to apply YET!!

The contact owns a 2012 GMC Terrain. The contact stated that while his wife was driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment. The contact noticed that there was oil leaking onto the ground. The contact inspected under the hood and saw that there was no oil on the dipstick. The vehicle was towed to the dealer and the engine was replaced; however, the failure recurred. The contact stated that the vehicle was consuming an excessive amount of oil. The contact stated that after two oil changes, the oil was extremely black on the dipstick. The contact stated that the engine had consumed over 2 quarts of oil after 2,500 miles. The dealer was made aware of the failure and informed the contact that an oil consumption test was necessary to diagnose the cause of the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 117,000.

We received a notice in the mail regarding our vehicle with our VIN #. And it mentioned our particular size engine had a recall for potential emissions part condition of degraded catalytic converter and/or oxygen sensors caused by excessive engine oil consumption affecting some vehicle from our year, make, and model. We were surprised to receive this notice because we always park in reverse and we had noticed how it was turning the curb side black coming from the tail pipe. We did receive one other notice before and took it to the dealership to have it maintenance but my honest opinion I do believe they did anything to our vehicle because it was running the same and also took it to Midas after taking it to the dealership because it ran the same. Anyhow I hope upon receiving this other notice we can actually maybe get reimbursed and actually get it fixed finally.

I am having trouble with these things now. The powertrain especially I have not had accident yet but it keeps going dead on me in the middle of driving down road. Causing me to have to put in neutral and restart. At this time the steering goes out. This needs to be repaired before an accident does happen. The drivers seat does not move forward or backwards. The tire pressure warning does not warn until it is at 20 psi.

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!!

Steering wheel locks and hard to steer while driving. System light comes on stating check power Steering. Also stabilizer light comes as well.

Wiper system failed, without notice or warning, while in use during travel on the highway, severely limiting visibility and creating significant safety event. No accident was reported as other vehicle passengers were able to assist the driver in safely maneuvering the vehicle to a safe stopping location.

Says powertrain control module failure. Also oxygen sensor on the my gmc app. It keeps cutting off in the middle of road.

My vehicle has excessive oil consumption including the need for frequent oil refilling, combined with audible rattle and knocking sound.

My Terrain recently started having “excessive” engine oil use. During the last two oil changes the dipstick has not registered any oil. I took it to a GMC dealership, but they only checked oil consumption after 1000 miles and the vehicle is at 121,000 miles currently. I don’t believe it is fair for them to allow an issue of this magnitude to continue, because it wasn’t using 1 qt of oil in 1000 miles, prior to the vehicle reaching 150,000 miles. I have to keep watching the oil levels in order to not damage my engine due to a known issues with the 2012 GMC Terrain. I also have to miss work & drive 30 miles to a dealership in order to have issues documented. I feel like they are just hoping I run out of time & mileage, since the recall is for a certain amount of time.
