13136 recall issued on XXX was visually inspected by [XXX] Chevrolet Pleasant Hill Iowa on 7/10/13. With the statement no further action required .Diagnostic inspection done by Thompson Buick Springfield [XXX] XXX the following codes flagged.B1517,P0606,P0700,P0AC4,P0BE6,P0BEE,P0C0B,U0140,U0293,U1817 The vehicle is owned by my wife's aunt a [XXX] widow the car is a critical Lifeline used by her niece to drive a 2.5 hour highway route from [XXX] to [XXX] where her aunt resides in a nursing home. On a return trip to [XXX]. The vehicle experienced catastrophic shut down power windows failed , air conditioner quit functioning and a mile of home the car lost power steering. Because recall inspection was done one month after the recall roll out XXX and then recall inspection was done XXX was a visual inspection that did not replace the known to be ,a future failure point part. After the catastrophic shut down, we took the vehicle to Thompson Buick [XXX]. To have a diagnostic service done which showed Parts noted in the original recall had failed the dealership was unable to do anything because the recall showed no further action completed . Service manager contacted GM representative who stated GM declined the request because the vehicle is outside the age and mileage guidelines for repair assistance GM does not allow for assistance Beyond 7 years or 50,000 miles Beyond warranty and service date. I believe this is taken out of context and the recall should be reviewed because the inspection was not adequate to solve the initial problem noted in the recall. There have been several changes to this recall to facilitate a review. But they have refused to have any other statement. All check engine lights activated. This misinterpreted recall failure has put an elderly patient and her caregiver in possible fatal conditions as well as innocent drivers.

during a regular drive the check stabiltrack system message popped up on the dash in the middle circle and then the little car with the squiggly lines behind it popped up and the check engine light came on and started blinking. Immediately I noticed lack of steering control, the car's speed was accelerating and decelerating on its own, jerking and stalling also was observed. As of now the car sits in my driveway because I don't trust the safety of it. I literally feared my life was in danger driving it because of the lack of handling and the acceleration shifts that were so random. So I returned home, as I pulled into the yard the vehicle jerked hard while I was attempting turn into the driveway causing me to hit my mailbox and damaged the side fender and front bumper. no one was injured but the car was damaged as stated before and I'm scared to drive it anywhere. The unpredictable behavior displayed in the vehicle puts other drivers at risk as well because I can't control the vehicle properly. so I'm guessing all in all its a malfunction somewhere in the electrical system. I have read about recalls in my type of vehicle involving the ESC and it appears to be what is happening with mine. As of now it sits in my driveway I need a remedy and fast because that was my only source of transportation and I'm a single mother of four with a lot to take of and no way to do it.

While driving stability trac, check engine light flashed and rpm, and speed gauges start going haywire. The car loses power even while accelerating, the steering wheel locks and car stalls. Then after 15-30 minutes the car starts fine and drives. Has happened at least 8 times. Took it to Buick dealer who ran diagnostic but unable to recreate codes but acknowledged a problem. Supposedly fixed it only to return the car a few days later. This is quite scary and dangerous as it happens without warning and while driving. Thankfully I wasn't on the expressway when it happened because all steering, power and brake function is lost.

Vehicle cuts off after driving for about an hour and a half or two after it gets hot from driving. Then have to wait a while like 10 15 minutes for everything to cool down and it will start back up again no problem. Drive 5 minutes more shuts down repeatedly. When it shuts down the dashboard displays service stabilitrak control and service anti theft deterrent system. Note. I've put a new starter on. A new throttle body. Mass airflow sensor. Upstream oxygen sensor. Changed the oil, checked wires. Changed the cabin air filter. Still not fixed. No service engine lights what so ever. Service stabilitrak and anti theft is all it's showing.

My car would not start and the malfunction indicator light was illuminated. The battery was charged and I took it for a ride then turned the car off. It would not start again. Waited until the next day and it started it again but there is hesitation in starting. It seems like this is the same thing that is listed as a recall but my VIN is not included.
