Is Your Silverado Sagging? Is your Cadillac Hesitating?
A number of General Motors drivers are calling into the 1-800 LEMON LAW hotline seeking assistance with hesitation on acceleration. There has been a Technical Service Bulletin issued by GM for all 2007-2009 Cadillac Escalades (including the EXT and ESV models), 2006-2009 Cadillac XLR and XLR-V models , 2007-2009 Chevrolet Silverados, Suburbans, and Tahoes, 2006-2009 Corvettes, 2007-2009 GMC Sierra, Yukon and Yukon XL models, and 2008-2009 Pontiac G8 models equipped with a gasoline engine and automatic transmission.
In these situations, the driver may experience a sag or hesitation when accelerating during a lane change, or when a lunge when trying to make a complete hard stop.
If you are suffering with this problem, you must bring your vehicle to an authorized GM dealership so they can address the matter. Please reference TSB PIP4112H. Do not allow the dealer to tell you this is a normal characteristic of the vehicle; it is not. Also, make sure that you receive a warranty repair invoice which clearly outlines the problem when you pick up the vehicle.
If you find that the problem can’t be fixed efficiently and effectively after several attempts, please get in touch with us either by phone at 1 800 LEMON LAW (1-800-536-6652) or via e-mail. We will discuss your situation with you and see how we can help.
