1999 Chevrolet Tahoe Vehicle speed control Problems

“I purchased my 1999 chevy Tahoe in 2004 with 87,000 miles from original owner. I received all maintenance records from original owner, as well as original dealership price/option sticker. I noticed once over 100,000 miles there was an electrical malfunction or problem, like a power surge anytime the power window buttons are depressed and when I accelerate, there is a surge and when truck slows down or is in park, there is n surge. There is sudden energy! There is also a problem with the dashboard/radio and switch buttons below lights working. They have failed! …”

“Vehicle fails to slow down when accelerator is released. When releasng the accelerator I notice that tachometer remains at the same RPM. At first this trouble was intermittant but has progressively failed more often until now it is continous. The only way to slow the vehicle down is by braking using the vehicle's brakes. When the engine braking was working ok, about two seconds after taking your foot of the accelerator it would slow down properly. I contacted the dealer on 2/22/2001 and he supposedly took it for a test run, however, the odometer in and out were identical, 26528 miles. …”

“The idiots on this site has injured my brain an there's a speed control issue not stopping these people from making stupid complaints get a grip people 90 precent of your complaints is normal wear and tear fix it for god sakes if not buy a new vehicle but guess what its gonna break down to.”

“When the gas pedal is released the car continues at current speed for 5 to 8 seconds before decelerating. The tachometer reading does not drop during this time. This happens at highway speeds and driving around town speeds. It's scary. It will decelerate and the tachometer reading drop when the brakes are applied, but I'm never sure.”

“While pulling out from a parking lot at 15mph and when picking at speed at 30 to 40 MPH, vehicle accelerated at 40 MPH and kept accelerating. Consuemr applied the brakes, and the vehicle kept accelerating. When the consumer got to a red light, turned vehicle off, and when restarting, vehicle did'nt accelerate.”
