"takata recall" - service air bags warning just recently came up on my dashboard when driving. Passenger side seat belt sounds off, and flashes to fasten seat belt when there is no passenger is in the car, and the air bag panel flicks on and off consistently. When I open the drivers door, there a tapping like sound starts and continues for five to six seconds and then stops. When I push the heat and air levers, it stops. When I turn on the air or heat, it will make the tapping noise and stop after a short while. The noise seem to be getting louder. When the car is sitting in the heat or when in the car just sitting and the car not turned on, the same tapping noise will occur. The noise sounds like a wood pecker sound. It sound like it is located in the cooling system area, close by the dashboard area.

Service traction control and check engine lights came on this morning. Then a message saying my engine power is reducing. I just bought this car 3 weeks ago. I called GM customer service and they told me there was nothing they could do, even though there was a recall regarding this because it was over the 120000 mile warranty (but I just bought this car 3 weeks ago!!!)

When the traction control system activated the engine idle decreased and the system could not locate the new throttle position. This caused the eng power reduction and fault warnings on eng tcs and scs to light in order to drive I had faults cleared and turned off systems. GM says the codes have to be read to fix.unsafe.

July 2015, "service stabitrac, losing power" lights came on. Took to local dealer and spent $600 for repairs. September 2015, same problems, took for repairs - no charge. Less than 2 days later the error code is back. Dealer has no clue on problem remedy. When the lights come on, acceleration is affected.

On the morning of Tuesday, June 2nd, 2015 just after 10am I was leaving my apartment managers office and when I was going in reverse and then to drive and touched the accelerator the Impala began to shake and on the dashboard it said the engine power reduced to half and there was a problem with the stabilitrak. When I parked in front of my apartment building, I turned the car off then back on and it was still shaking/ idling rough and on the dashboard is continued to read, "engine power reduced by half" and mentioned stabilitrak. The engine light was also on during this time. I left the car and returned 10 minutes later and engine light was still on and while it no longer idled roughly, it still had stibilitrak on the dashboard.

Driving along and car just accelerated and could not get it to stop or slow down. Traction control light came on, engine reduce power, low engine power, service stability trak, check engine light. I was pushing down on the brake trying to get the car to stop or at least slow down but the car seems as if it was getting fasting then it made a jerk and I bumped my head against the window, and my foot got stuck under the pedal and knee got jammed. My mom got hurt also and being jerked back and forth.

Car was going about 40mph. Reduced engine power warning, loss of traction control, and stabiltrak to be serviced. GM will not cover under warranty and is a common problem. Some cars will automatically just shut down.

I made an appointment with the Chevy dealer after receiving the recall notice. When we took the car in as instructed, we were told they did not have time. But they did have time to try to sell us some services from them. What is the companies responsibility to fix our car?

I was driving down the highway on the homestretch of a roadtrip from pa to fl when the "service stabilitrak", followed by "engine power reduced" message started flashing. The two lights on the dashboard also went off. Since I was in the middle of the highway, I was unable to find a good place to address the issue, and I figured like most times the "check engine" light goes on, that it was something that I could wait to deal with when I got home. I continued driving for about 15 minutes and then the message changed and said "disabling throttle" or something to that effect, and I felt the engine losing power. I was in the middle lane, doing around 55 miles per hour with cars all around me. I immediately put on my four-way flashers and fortunately people in the right lane slowed down and let me coast to the shoulder but it could have been disastrous. I sat there for a few minutes trying to figure out what to do. Finally after a few minutes I decided to try starting the car again and it started, with just the check engine light on and I was able to continue on my way. Since then it has continued to occur intermittently. I took it to the dealer, but they told me it was a sensor in the gas pedal but that it was not under warranty.
