My lift gate door fell and hit me in the head out of no where and my car is not on the list for the recall for that exact problem. My airbag indicator goes off all the time even if no one is in the front seat. My speedometer barely works, it goes completely around and I can't get it to reset. I took it to the shop just to be told it's a sensor that causes it along with the slow cranking but they didn't know which one it was because my car has 4.

Takata recall it keeps shutting completely down in the middle of highway and this affects everything steering, complete loss of power to vehicle. No codes to indicate something is wrong !!!! Extremely dangerous this has continued to occur even after parts have been replaced brand new. More than 5 times already. This will most certainly lead to death. I have 3 children with me at all times. That's 4 lives that could be lost because of this problem!!!! . We have been extremely lucky because it has shift down in the middle of the night and bridges where there is nowhere to get on the side but remain in the lanes where traffic is 70 MPH and up!!!! This needs to be recalled immediately!!!!

On 4 separate occasions within a 3 week period the vehicle would accelerate while driving without driver prompts or control (rpms revved from 2000 to over 6000 and speed would increase from 50 MPH to over 85 MPH with accelerator pegged to the floor.) the only way to correct this was to put the vehicle in neutral, coast to the side of the road, stop the vehicle and turn off the engine for 10-15 minutes, then restart it and it would run normally for short periods of time. If I drove the vehicle for more than 30 minutes at a time it would react this way every time and nearly caused me to hit 2 vehicles on the interstate. On one occasion I had to impact a guardrail to slow the vehicle down. I took the vehicle to a certified gmc dealership who stated on both occasions they could not repeat the problem after driving it for 5-10 minutes or less than 15 miles. When I informed them that it only occurred after 30-45 minutes of driving, the technician stated he didn't have time to drive the vehicle that length of time or distance and went on to say no diagnostic codes were tripped so there wasn't any repairs he could do or that gmc would authorized. The vehicle was under warranty. I researched this problem online at www.carcomplaints.com and found over 25 similar issues and complaints from other owners of the same year make and model. Two of which resulted in a crash with serious injuries to the occupants. I was forced to sell this vehicle at a 2554.00 loss and will now be filing a class action lawsuit against gmc and the service dealership I dealt with after I compile the required evidence from the other 25 owners with the same problems. I find it hard to believe that you would allow this to continue knowing full well injuries had been reported to the federal safety agency in previous complaints. I may include the federal safety agency in my class action lawsuit if my attorneys think it to be a good idea.

There is a recall on the convertrr post that causes the engine to seize up and pull to go into the engine.. When started nothing comes out of the exhaust pipes as they are clogged making it dangerous to operate.. The recall ignoramus this year, make and model for the same problem however after contacting gmc repeatedly they say that it doesn't include this exact VIN..I have already had the engine replaced once due to this problem and ther dealer failed to diagnose it properly and acknowledge that it had the same problem as the recall in other vehicles ofthe same make and model... The vehicle sizes up at any rate of speed and the exhaust is clogged making the vehicle dangerous to operate

When I accelerate and get to 40 MPH the car begins to shake randomly, intermittently. Then the service engine light came on, then the traction control shut off and the light to service traction control came on then the car drop the speed from 60 MPH to 10-20 MPH! When I tried to accelerate it did nothing ! The speed wouldn't increase at all then it started running fine and then a few miles down the road it did the same thing, dropped speed from 60 to 10-20 MPH! I pulled over and shut the car off and when I restarted it the same lights were on and when I tried pulling away it would only go up to 10-20 MPH for a few miles then it got up to 60 MPH for a few miles just to drop again! I had my 11 month old grandson in the car that was dangerous! I was on townline road and manito blacktop that are very high traffic

When travelling home on the highway after school shopping with my two children my vehicle suddenly reduced power, became uncontrollable and wouldn't allow me to get out of the way of the rapidly approaching vehicles behind me in time. I was able to get to the shoulder, after the reduced engine alert appeared. Stabiltrak was also disabled and one more feature I cannot remember. I had to shut my vehicle down and sit with two children in the car waiting for the car to somehow right itself. After 10 minutes I tried turning it on and the errors were gone and the car drove again, except rough. I took it to the local auto store and the diagnosed it with the code reader as tac. Throttle body. The person at the counter said they see this all the time with this vehicle. In fact, it should be a recall since it's so common and a clear flaw in the design. To the tune of $199 you can replace the part and have the same thing happen all over again at some other random, unsafe time! Thank you gm for yet another unreliable family vehicle. I will have no choice, but to replace the part, as this is the car used for every day transportation in my household to school, work and back. Researching the internet horror stories can be found everywhere. It seems tragedy has to happen to make this $200 part a recall. Please redesign and replace. This mom cares for her kids.
