Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

While on trip home from jacksonville my car ran hot at 62,000 miles while previous warning of any kind. After a lot of towing expenses and uncessary replacements of other parts to try and fix it, I finally had to again have it towed to dealer. There I was told that it was a faulty chain that comes from engine that drives the water pump to work correctly. Well, GMC knew of the problem. As I found out, they had put an extended warranty on that part. No recall, no notification to owners that this could become an issue. I was on interstate 10 and had the car stalled in traffic I would probably not be here today. They are fixing the chain but now all of a sudden they are finding all kind of other problems while in the motor. I am trying to at least get my towing reimbursed. This is another example of GMC trying to cut corners instead of issuing recall to correct the faulty part. I am furious.

While driving message read reduced engine power lost all power could not control the steering wheel! then the car shut down and continued to roll down the highway.almost got hit by other cars from behind. Very frightening for me I almost got a panic attack. I managed to stop the car on the shoulder of the road with half of the car still blocking other will not start. The battery is new.I have done research on social media and there's thousands of GM customers who have or are facing the same issues. Is this another cover up by GM that's continuously ignoring this problem and the consumers are paying thousands of dollars in this repair. I was told I need repairs that will cost $4000 dollars on a 2011 GMC Terrain car I got a year ago. This is ridiculous. Who is fighting for the consumers?

My GMC Terrain has stalled out while driving at highway speeds 65-70mph (I wasn't turning, stopping, or switching lanes). Completely shut off, no power steering or power brakes. I was able to coast over 3 lanes of traffic, in rush hour, and come to a stop on the shoulder. The truck would not restart. Previous times it stalled, and I was able to put it in neutral and turn it back on. Today (January 6th, 2016) however, it would not turn on. It would crank, but that's it. I called a tow truck and have it at the dealership now.

Car completely shuts down and loses all power/activity after starting it up, putting gear into drive, and trying to accelerate. Wheel gets stiff and car stops moving. This first happened within a year of buying the vehicle and has happened a second time mid ownership. During these times, the car just would not start for about 30 mins to an hour. Lately and several times a week now since mid-October, the car will start but completely shut down to the point where the car is shutting down at red lights, stop signs and anywhere I have to stop. It may take 3-5 times to repeat the process of starting the car and putting it back into drive before it drives without shutting down and me making to my destination.

I had purhased a 2011 GMC terrian and have gotten three letters saying don't bring in to dealer until the problems happen one side -impact circuit cause-airbag-readiness light illuminate and the service air bag message to display. GMC extened the protection for 10 years or 120,000 miles. The second that was sent the steering same protection and the third letter for oil consumption which it is doing now. This not safe for my wife and me or the any other passengers. What is your addvismentfor me.

Now I did not have an incident. Im writing you because I very recenrly bought a used 2011 GMC Terrain sle. And like everything else I do my research. And the one thing ive noticed is a whole lot of people have had the same very serious problem with there car. The stability control light comes on and the reduce speed light as well. And immediately slows the vehicle to a speed of 10 mphs. As well as locking the steering wheel. Unbelievably dangerous. Ive personally read almost 100 cases of the same thing all across the country. All with this same vehicle. Its a miracle nobody was killed. Now for my point. What are you and GMC doing waiting to fix this problem. Are you waiting for somwone to lose there life. As a parent myself this is very troubleing.if me or my family is to be harmed because of somwone elses neglegence would be a terrible tragedy. Someone needs to fix this problem. Ive read the reports I have read these peoples pleas. And nothing is being done. How do you sleep at night

  • 78,000 miles
I was at a busy intersection with my 19 month old son at 5:00pm on Friday, March 27, 2015 when my car just died on me. After having it towed to a non GMC service station, they informed me that I had no oil in my car. I was taken back by this because it had not even been 1500 miles since my last oil change and I had no warning at all, my oil light or check engine light never came on in my car before it died. I have been more than up to date on every oil change since I have owned the car in September of 2013. Due to no oil in my car, there was extensive damage to the engine resulting in me having to replace the engine in my car. GMC informed me that this is not a recall and it should be!!! this is completely dangerous and GMC will not reimburse me for the engine that I have to put in my car even though this was not caused by me.

Terrain 4-cyl

  • 63,000 miles
During a normal commute on route on 2/15 received about 3 miles into the drive received a warning error - loss of engine power and the car would not accelerate. The car started shaking violently and received a stabilititrak error. The car was pulled to the side of the road and placed in neutral. The shaking became worse and the car was shut off. After two minutes the car was started again, with no issues and was driven 6 more miles without issue. After 6 miles of driving the same engine power warning and stabilitrack error came back. The car was violently shaking and the driver shut it off. It was towed to the dealership. The dealership received one code for the throttle sensor positioner. The code was reset and a loose connection was diagnosed as the fault and returned to owner. Five days later the car was started in the garage. Upon startup it started again to shake violently. The car was put in reverse and began to shake violently and the driver received a stabilitrak warning light. The car was shut off and was again towed to the dealership. The dealership found two codes crank position sensor and misfire. The car was driven five miles with no issues. The dealership cannot locate the root cause of the problem. This undiagnosed issue posses a severe safety risk to the owner of the car and family if it were to occur again while driving in congested traffic or on a highway.

Terrain 4-cyl

  • 61,000 miles
I was traveling down the road with my family in the vehicle when all of a sudden the vehicle decelerated and starting vibrating and operating roughly. The stabilitrak/reduced engine power trouble light was displayed. This certainly became an immediate safety concern because the vehicle could only accelerate to 15 to 30 mph. I was able to manage the problem long enough to return home, which was only a few miles away from the onset. I have always had performed the required scheduled maintenance on this vehicle. However, since purchasing this vehicle new in 2011 and experiencing multiple recalls and a air bag safety issue and now this, I have become concerned about the reliability and safety of this vehicle. The vehicle has only 61,000 miles on it and should not be experiencing this type of problem. I believe GMC corporation should make a concerted effort to recall any of their vehicles with this problem.

Terrain 4-cyl

  • 46,200 miles
I was driving on the highway at 60 mph and all of a sudden lost power. The reduced power and check stabilitrak messages appeared on the screen. I pulled over to the side of the road and turned the engine off. I immediately tried starting the vehicle again and it did, so went on my way. Got down the road about three miles and the same thing, so pulled to the side of the road and turned the engine off. I tried to start the vehicle, but there was no response, everything was dead. I waited several minutes and tried again and it started. I continued on my way and didn't have anymore trouble getting to my destination. A couple of days later, the same thing happened except when I tried to turn the vehicle off, it continued to run very roughly and then finally shut off. It did start again and had the engine light on. I've had the vehicle to the local GMC dealer when the first incident happened, however when they tried to read the codes, there were no codes to read even though the engine light was on. I was told everything checked out fine. I was down the to dealer again today with the engine light on again, but before they could check it out, the engine light had gone out. To me this is a very serious problem as it can very easily cause an accident. So far I've been lucky that I haven't lost the power steering or brakes.

While driving the vehicle stalled from 35-40 mph to 5 mph. A message came on the screen " engine power reduced". had I been on highway that would be ended in accident. Contacted GM and everyone I have been talking to them seems to be reading a script to me.
