OCCASIONALLY, WHEN STARTING FROM A STOPPED POSITION THE ENGINE WILL REV UP AND THEN THE TRANSMISSION WILL KICK IN TO GEAR. OCCASIONALLY IT SLIPS ON HILLS ALSO. WE GENERALLY DO NOT HAVE TO MERGE INTO HIGH SPEED TRAFFIC BUT IF THE TRANSMISSION SLIPPED AT THAT TIME THERE COULD BE SERIOUS CONSEQUENCES. THE DEALER HAS BEEN UNABLE TO FIX THE PROBLEM AFTER FIVE VISITS, AND APPARENTLY WILL NOT DO ANYTHING UNTIL THEY THEMSELVES EXPERIENCE THE TRANSMISSION SLIP. *TR

REPORTED THAT CAR WOULD JERK (KICK INTO GEAR LATE) WHEN ACCELERATING FROM STOP TO START. AT 74,000 WE MADE OUR FIRST CLAIM WITH LOCAL DEALER. THEY COULDN'T DUPLICATE THE CONCERN. BROUGHT CAR IN TWO MORE TIME BECAUSE IT GOT WORSE. FELT LIKE SOMEONE WAS HITTING ME FROM THE BACK. MY CAR OFTEN KICKS OUT OF GEAR ON A LEFT TURN. ON TWO SEPARATE OCCASIONS, I WAS ALMOST T-BONED. THEY NEVER FOUND THE ISSUE UNTIL 121,000. THAT WAS WHEN THEY DECLARED THAT THE TRANSMISSION NEEDED TO BE REPLACED. GM DOESN'T WANT TO COVER THE REPAIR NOW THAT THE VEHICLE IS OUT OFWARRANTY. I HAVE RESEARCHED AND FOUND WAY TOO MANY TRANSMISSION ISSUES WITH THESE MODEL VEHICLES. GM REALLY SHOULD INVESTIGATE THIS CONCERN. I ADVISE ANYONE TO PESTER GM ABOUT THIS CONCERN. AFTERALL, WE ARE THE CONSUMERS. UNFORTUNATELY IT'S TOO LATE FOR ME, I DON'T TRUST THEIR PRODUCTS ANYMORE. *TR

AS I WAS DRIVING THE ENGINE LIGHT CAME ON AND THE DISPLAY READ REDUCED ENGINE POWER. THE CAR SLOWED DOWN AND RESISTED AS I ACCELERATED. I CAN ONLY DRIVE ABOUT 20 MILES PER HOUR. THERE IS NO WARNING AND THERE IS A DECREASE IN ACCELERATION. THERE WAS NO WARNING AND I HAVE MY CHILD IN THE CAR. THIS IS VERY DANGEROUS. *TR

Official recalls
2Jun 23, 2014
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence & remedy
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.

ON CERTAIN VEHICLES, THE FUEL TANK IS MISSING THE ADHESIVE LAYER THAT BONDS THE BARRIER LAYER TO THE OUTER SHELL OF THE FUEL TANK.
Consequence & remedy
