While driving, the traction control light turns on. Then the gauges all start fluctuation. The dash reads service park assist. Then service stabilitrak. It does not run properly. It shifts hard. I-??ve had it to the dealership twice now. The issue is still not resolved and it-??s going back next Monday. I feel it will again not be resolved after reading multiple forums of others having the same issue after spending thousands of dollars. This is frightening and stressful to say the least. My car has less then sixty thousand miles on it. I should not be having this issue.

Showed stability track. I was driving on the highway when it showed service stability trak then engine power reduced. It took my speed from a 65 to 35 in an instant causing me to almost crash. Then the car started to jerk as I tried to drive to find somewhere safe.

Tires constantly lose air, sometimes very suddenly and normally while the vehicle is in motion. Three of the tires have been affected.

Extremely disappointed with my 2013 GMC Terrain. It has a 2.4 cylinder engine that consumes too much oil between oil changes. A technical service bulletin was issued by GM for the problem but they have not done a full recall yet. Vehicle was stalling due to low oil issues. Intake solenoid had to be replaced because of low oil levels. Transmission fluid leaked from trans torque converter seal, left rear wheel hub had to be replaced due to bearings going bad all with just 52K miles. The engine specifically in my vehicle is a safety hazard/concern for anyone with a family. My wife is a nanny and does not drive the vehicle aggressively. I had driven this vehicle not very many miles on a new fresh oil change and the next time I went to check my oil the dipstick had no oil on it!! I was furious because there was not a light that indicator that came on in my vehicle to tell me I had low oil or anything!! also have a problem with the loud noise of tires when going down highway.. I did like this vehicle when I first got it but ever since then I have been disappointed in what is going on..

We bought my daughter a brand new GMC Terrain. Her old GMC had over 200,000 miles on it. She had a blown out tire prior to this incident. She was not driving fast and there was not reason for the tire to blow out. She is on her way home from a friends house and goes over a railroad track, not speeding. Another tire blows out. Has to get car towed. The tow car to gmn dealership. Days in shop airbag issues, tire had to be replaced. Takes over 4 days to be repaired has to go back. Over $1700 bill. This is second time this has happened.

1. on August 17, 2014 my virtually new 2013 GMC Terrain with less than only a few thousand miles of use crashed due to the General Motors corporation [GMC] GMC Terrain defect in design and manufacturing of this vehicle as confirmed by an official GMC dealer as recorded herein. The details of this incident are recorded below and represent only a small fraction of my many attempts by usps mail, email and telephone to contact GMC and to register my complaint. GMC has not made any meaningful response to my contacts and, in point of fact and in truth, GMC has acted to intimidate, terrorize and bully me! 2. during the morning of August 17, 2014 in my 2013 GMC Terrain while traveling South on I-95 in the right lane in Virginia, near chester, Virginia, the left front wheel suddenly separated and detached from this vehicle causing the steering of the vehicle to become disordered and deviate to the left and to crash into the concrete barrier separating the North bound lane of I 95 from the South bound lane. My damaged vehicle was eventually towed, after several hours, to a GMC dealership in chester, Virginia and then to second GMC dealership in chester, Virginia where temporary repairs were made after many delays and lack of availability of parts and other GMC glitches. After the temporary repairs were effected six days later, at 5:55 pm, my vehicle was returned to me. A copy of the repair facility of the GMC dealer: Strosnider Chevrolet, Inc., attesting to these facts, is reprinted below wherein it is recorded: 'the left front wheel, while driving, began to come loose causing the steering to be distorted resulting in the vehicle striking the concrete center divider and the wheel completely cast out from the vehicle and the ensuing body damage' for your information and for inclusion in my file.
