Report Receipt Date: MAR 15, 2013 NHTSA Campaign Number: 13V097000
Component(s): ELECTRICAL SYSTEM , POWER TRAIN Potential Number of Units Affected: 26,582 Manufacturer: General Motors LLC
SUMMARY: General Motors (GM) is recalling certain model year 2013 Buick LaCrosse vehicles, manufactured between April 25, 2012, through March 6, 2013, and model year 2013 Cadillac SRX vehicles, manufactured between May 29, 2012, through February 18, 2013 for failing to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 102, "Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect."

CONSEQUENCE: If engine braking is unexpectedly removed, it may increase the risk of a vehicle crash.
REMEDY: GM will notify owners, and dealers will reprogram the transmission control module free of charge. The recall is expected to begin on March 28, 2013. Cadillac owners may call 1-866-982-2339. Buick owners may call 1-866-694-6546.

car, ever, that I can recall...without manually shifting into 2 or 1. My Blazer is MT, and even it doesn't engine brake for several seconds after letting off the pedal. IIRC, engine braking puts NOx emissions through the roof. GW

There isn't much engine braking but you can definitely tell the difference between what little there normally is and none.
