Twice had to have wiring repaired because animals ate the wiring. Both were caused by GM using soy based insulation on wiring that made it a delicacy to the animals and caused them to eat through two wiring harnesses, one of which GM no longer makes. The other complaint is the timing belt has stretched and is now in need of replacement at a cost of $4500 to $5000.

The defroster/ radio control/ heating area stopped working. Upon visiting a mechanic was told they never seen this or heard of this happening before and quoted me over $1,000 dollars to fix stating that due to Federal Law they have to give an estimate but this problem not being in their system they came up with an estimate based on parts and labor. Upon searching online I found a recall for this issue dating back to 2009 recall number was 09V489000 but was never informed about this and while looking up my car it-??s not listed but being a safety issue should still be current which it is not.

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!

While driving the stability track service lift comes on, the ABS, brakes, service all wheel drive, as well as the service power steering at which time I lose power steering. It also feels like it is accelerating sluggishly when drive sometimes. This happens and goes off sometimes with out me turning the car off or stopping but other times I have to pull over and wait a few minutes after turning the car off. It happens various times. At one moment it is driving fine and then these lights come on. When taken to dealership the lights have gone off and they get no codes.

The radio will go blank causing me to not see the screen

- Ocala, FL, USA

Engine - slows down and speed up and jolt as it accelerate in speed. Heated seats - a month after purchase they stopped worked oil pump - the filter gets clogged with metal shaving and would not allow the oil to get to the engine. As a result, I had to get oil changes 3 times in a month. Dash board and stereo light would flicker and dim. Stereo would repeat words and get stuck in one place. The wind shield wipers stopped working during a rain storm and were wiping in two separate directions at the same time.

- Long Eddy, NY, USA

Vehicle intermittently (drives fine for a week, day, month with no problem) dies on me while driving, or wont accelerate above 35mph. System says overheat condition but the temperature gauge does not say it's overheating. Dealership runs diagnostics and says nothing wrong but it keeps happening unexpectedly. Causes problems on highway and is dangerous. 3 mechanics said bad ECM, but Chevy dealership will not replace or reflash ECM. I've spent thousands of dollars flushing radiator, replacing thermostat, replacing camshaft sensors, mass airflow sensor, running diagnostics, renting vehicles, and nothing helps. I see where there are recalls of GMC Terrain ECM's but not mine? this is getting ridiculous. I need help. I owe more than the car is worth and I'm paying so much to diagnose something that should be taken care of by GM.
