Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

Dealer should advise the customer the specification for speedometer needle accuracy is +/- 2 MPH at any given speed when looking straight at the needle.

Dt*: the contact stated the vehicle's electrical system was not working properly and had lift gate, lift rear glass and acceleration problems while traveling 35 MPH. The contact stated the pulse power that was obtained from the battery was very low which caused the lift gate to not open. The vehicle was taken to the dealership for a diagnosis test.
My rear hatch will not open with key pad or from in side the vehicle. Why don't you have a key entry for this kind of problem? This is a safety hazzard.
Engine started misfiring while on highway. Engine light came on and was blinking. I pulled off the road and had the car towed to dealer. The result is #6 and #8 are misfiring and also were told that 2 manifold bolts on right side of engine were broken off in engine body. If they cannot get the bolts to back off they will have to pull the head to drill them out on the inside.
Vehicle stops running. Engine dies happened four times, three times at 70 to 80 MPH on 6 ln. Freeway have to try and steer and use brakes with no power. Once to the side of the road let sit for a few minutes and it starts up again. Have had it to the dealer and they say they have no idea what is wrong when they put on the computer. I feel that his is extremely dangerous! It could get us…
