Vehicle Shudder Problems of GMC Terrain

Driving 50 mph on the highway, my car decided to 'reduce engine power' and 'service stabilitrak' came on, immediately making the car slow dance forcibly to 25 mph. The car was shaking and stepping on the gas did nothing. That's dangerous, because the person behind me has to swerve or hit into the back of me for sudden drop in speed. You guys should know better! happened twice in one day. I had to restart the car, and it happened going onto the bridge. Someone could be seriously hurt, or killed. Do better!.

Only a month after purchasing my vehicle I started to feel a wobble in the front end when accelerating up hills and turning while on the gas. I took it to the dealer and they changed out the front tires stating that the problem had been fixed. Once again while driving the problem persisted. I took the car back to the dealer again and they said that they could not find anything wrong and suggested that I make an appointment to go for a drive with the mechanic to show them what is happening. I made an appointment. A day before the appointment I received a call from the dealership stating that an employee recently purchased the same car and they are having similar difficulties. They found online that GMC was requesting information from dealers about the problem and was told that I now need to wait for GMC to come up with a solution. My car shakes every time that I drive it, it's awful, and it only has around 6,000 miles on it. I'm not sure what to do because the dealership told me that I have to wait for a solution. They are not even trying to fix anything at this time. Please help.

My 2011 GMC Terrain while driving 45 miles down road the lose of power light came on and the car immediately slowed down causing me to almost have a accident. The car would run but shake real badly. I stopped the car and turned off for 5min and restarted and was able to make it home but had to do this at least 3 times getting there. I don't know what is going on, but I do know I almost lost my life in the process. My car seems to burn aiot of oil too here lately, like its drinking water.

Vehicle shuts off when slowing to a stop and have to restart in order to accelerate. That was looked at and �fixed� and now the vehicle shakes when slowing down and headlights dim as if it is trying not to shut off. Engine is very rough and rattles while starting to accelerate and accelerating. When brakes are pushed the car starts to turn off while in motion. When stopped, car shakes and there is a very hard knocking coming from the engine.

Third time while driving on city streets the car begins to shake and stall. I pull over or stay in place as the car proceeds to turn off. The service stability traction and engine lights light up and the car dies. Each time I am able to turn the car back on within a few minutes.

Oil consumption issue: I realized about 3 months ago that my car engine would shake a bit on start up and during idle. I took it into the dealership for a diagnostic test and was told that there was very little oil in the car and that it was burnt. I was very surprised because I have never had an issue like this before. So we got an oil change and that was that. Engine still shook on idle and during startup. 5000 miles later I realize that it is time for an oil change and check the dip stick and find that nothing appears on it, indicating that it is short at least 1. 25 quarts. I fill it up with 0. 5 quarts and still nothing on the dip stick. . Read more...
