“Thus far, nothing has happened with my vehicle, but there has been a recall in effect for the airbags in my vehicle for well over a year and nothing has been done to replace the airbags. I am also having some electrical problems with my truck not shutting off when I remove the key, and the interior dome lights will not turn on when the button is pressed (this has all began since the recall was initiated but not taken care of). …”

“I am very disasified with the way the issue has been handled. I drive a 2010 Chevrolet Avalanche ltz with 111,000 miles on it. I purchased this vehicle in 2005 with 38,000 miles. A year later during the summer time I began to have electrical issues (while in motion vehicle guages start spazzing out going up and down, radio cuts in and out, door locks cycle up and down and vehicle stalls, doesnt seem to accelerate and shift into second gear. I have been stranded in the middle lane of the freeway traveling 60 miles per hour when suddenly it begins to act up. …”

“I was driving on a bridge when the check engine light came on and the engine power reduced. The truck immediately dropped to below 30 MPH and I could not accelerate up the bridge and barely avoiding an accident, as this was in a heavy traffic area. I was able to get it to the dealership and are working on it now. This if the fifth time this has happened to my truck. My wife and I just sold our 2007 Chevrolet tahoe and the only reason was the engine power reduced error occurred on it seven times, three in month prior to selling it. …”

“I was on vacation and had my Avalanche running while I packed it up to return home. After about 5 minutes of running idle, the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak. This had happened to the truck three times before and each time they replaced the accelerator pedal positional sensor. (I also had a 2007 Chevrolet tahoe, and after having it repaired seven times for failing sensors and going into reduced engine power while on the highway three times we were forced to sell it). We are very familiar with this issue! …”
