I was driving down the road suddenly check engine light came on speed reduced get a reduced power/traction control message and speed drop to 40 in matter of seconds engine running very rough. Almost caused a accident due to this happening at the morning rush hour on commute to work. I looked online this seems to be a common complaint that there needs to be something done about it. I have had other issues (eg: Steering mid-shaft failure front end shimmy, brake issues, connector to rear defrost melting, wires in shifting console breaking to where couldn't remove keys or get out of park) with this vehicle and called GM about them and they assign a case number and tell you sorry you will need to pay and keep receipt if there is ever a recall issued.

After driving it for many years and having no problems, I drove it a short distance and parked and could not remove the key, I tried taking it out of park and putting it back in park and after trying that several times and it not working I tried (jiggling the shifter when it was in park) and it released. It happened again for the 2nd day in a row. I will bring it to a local repair shop after the weekend is over and see if it is a bad wire or something.

While driving car started to jerk and hesitate the check engine light came on along with a message of reduced engine power. Could not drive the drive over 5 mph. Was able to get to the side of the road. Had to push the car into a parking lot as the engine will no longer start but cranks over fine. Had to buy a scanner to read the code because the car was not able to drive to a auto repair shop or auto parts store to read the codes. The PO641 code was set. Checked and tested the sensor wires for the 5volts every one that I tested showed ok. Replaced the gas pedal assemble because of the code that could be a source of the problem no difference. Cleaned the throttle body unit no change car will not start.checked and gave all the wires a good pull and or tug to wiggle the connectors and took apart all sensor connections no corrosion was found.all grounds appear to be good. No broken wires are found no blown fuses were found.after 2 days was able to start engine with the message reduced engine power and car died again and would restart but not idle. Was able to rev engine and keep it running but once it idled it would die and sometimes not restart this time car is unsafe to operate on any roadway because it might die and random times.

The heat only blows warm air during acceleration. Once idle, the warm air turns ice cold. My car went to the dealership multiple times to be repaired and every time, it would work properly for a few days then go back to not working. After the 3rd "fix" (the "fix" was something different every time), the dealership told me I just must know not how to work my heat because I "keep breaking it". this is a known issue on this vehicle and even the dealership does not know how to correctly repair the problem!!

The vehicle failed to shift into park. The vehicle was taken to the dealer where the technician diagnosed that there was a broken wire in the BTSI solenoid terminal which needed to be replaced. The vehicle was repaired by re wiring the ground wire to the shifter where the pin had broken. On May 3rd the key got stuck in the ignition and would not come out. Let the car sit for 24 hours the battery died and the key released out of the ignition. Took the car to the dealership on May 5, 2014 and the shifter wires were re constructed. Car still acts as if the shifter is not going to shift.

I was going over the vehicle for the season and found I had a leak in the power steering line. The line effected was covered with a ribbed plastic sheathing like what is used for a wire harnesses. The sheathing caused road salt to build up and corrode the line, causing a leak and loss of power steering. There were two lines held together, side by side, with a plastic bracket but only one of those had the sheathing and I cannot understand why it was there. I also found a wire that overheated and melted the insulation and left the wire bare. It's located behind the power steering pump as viewed from the passenger side of the engine compartment under the plastic that displays the engine size. The plastic is held down with a couple of pins that the plastic pushes down over when installed. The dealer couldn't tell me what the wire is for when I called to explain what I found.

As I was pulling out of a parking lot the vehicle just shut off with no warning. Thank god I wasn't going too fast as I had no steering, no brakes, etc... checked the GM website about the recall and it states to take everything off the key ring except the key. Well I've only got the key on the ring so that excuse doesn't wash. I called the GM customer center and they told me that my car wasn't included in the recall with the faulty ignitions, then they hung up on me. Well it should be. I think this ignition problem is a lot bigger than they are admitting. What am I supposed to do, I can't afford to fork over big bucks to a dealer. I'm a single working mom.

This is in addition to claim # [xxx]. when I turn the heat or air conditioner on and adjust the knobs there is a loud clapping sound on the passenger side dash board. It last for about five minutes then stops very annoying. When will these cars be recalled to fix these problems.

The first instance I was driving and the "service brake system" flashed on the display. I had all brake pads replaced at dealer on 1/3/2013. 2/7/2013 I was in traffic and the car suddenly slows to about 10 mph and would not accelerate the dash then displayed "reduced engine power" and the check engine light came on. On 2/14/2013, I had the throttle positioning sensor replaced and at the same time had the rear defrost wiring repaired because that had not been working for over a year. On 3/4/2013 the car would not start by the factory remote start, so went out and started the car with the key, when I returned to the car the vehicle would not start at all the chime would sound the lights on the dash flashed but no start. I waited a few minutes then tried again, the car started briefly (50 seconds) "reduced engine power" appeared on the dash then it shut down completely. I looked under the hood saw the battery attachment was loose, tightened that up and then the car started up. However, the car radio (factory radio never replaced), the chime, or the ticking of the turning signals no longer work. I have an appointment with dealer on 3/14/13, but the car seems to be failing all around. In reading Chevy/GM forums, there are thousands of Chevy owners experiencing these same issues, Chevy/GM needs to take ownership and investigate these vehicles to determine the root cause of the problems. Nearly 3000 dollars later in dealer repairs is not getting to the bottom of the issue. I was nearly in a crash due to the reduced engine power issue and that was scary enough to make me not want to drive this car or an at all.

As I was driving on the highway, suddenly reduced engine power came up on the dash board. Followed by the steering wheel locking up and the car shutting off. After 20 minutes the car started again, but now I drive witha constant fear of this happening again, and what if my children are in the car next time! I have a constant issue with the power steering line leaking, although I have replaced the pump, and the fuel line. I feel like I am throwing my money into a bottom less pit. What do I do from here?
