The vehicle continually goes into "engine low power mode" while on the highways. This is now occurring daily. I've tried to get it fixed but no one seems to know what it is. I am very fortunate that no one has hit me when the vehicle goes from high speeds down to 20 miles per hour with no response by pressing the gas pedal. There have been multiple things failing on this car: Passenger side window no longer opens, cruise control will not work, 2 of the 3 chargers in the car do not work (after fixing those fuses, they just blew immediately) power locks went from barely working to not working at all, the latest being the low power mode and traction control being activated in the heat of a Tennessee spring (already 80 degrees) - it's not a water issue. The first few months I had this car it was in the shop almost every weekend. I've gotten all the recalls fixed when they required it and I keep up with maintenance on this car. It has the usual break downs but this is the least safe car I have ever driven (and I have driven around twenty long term, ten more short term).

Since 1/2012, intermittent malfunction of power steering and engine operation at highway/street speeds occurs. Vehicle since has been inspected for incidents by certified dealers/auto repair shops. Problem continues forcing the driver to veer off the road without steering and/or power, putting the driver and anyone in the path at risk of injury/death. My research due to the most current incident led me to information released from the National Highway Traffic Safety Administration dated April 1, 2014 stating that 1,340,447 cars affected with this problem. NHTSA campaign # 14V153000, GM recall #:N140115. GM knew this information. On 4/23/14 I submitted a complaint to the NHTSA, and GM. 2 GM employees denied the recall/services, yet eventually admitted that they knew about the recall which would be made public 4/28/14, yet notices to vehicle owners will go out after 4/28/14. GM continues the practice of not informing the public.

Brake lights flashed intermittently when I was not braking. I was stopped and informed of this by at state trooper. "check engine" light was on. The cruise control has disengaged involuntarily since 2005. I had a new brake pedal position sensor installed, but the cruise control still disengages and the check engine light comes on during trips of more than 10 miles.

When I start my car, I can hear some click noise from transmission or brake control. I had not been aware of that could lead to server accident afterwards, because the car is pretty new and I keep it in maintenance periodically. On November 13, 2010, I drove at 40-50mph, along hwy 128 to mendocino. It ran out of control, rush a small mound of road side, rolled over on the road. I was trapped in the car, all frond windshield was broken. I escaped safely. I doubt the control has some problem, lead the car imbalance.

Failure of power steering while accelerating vehicle. Steering direction becomes impossible to change until acceleration ceases. This has supposedly been fixed by the dealership two times previous to today. The last time it was fixed was only two weeks ago and while I was driving the kids into school this morning, the steering locked up, the dinging sound turned on, and the message board read power steering along with a tool that lit up on the dashboard.
