1994 gmc suburban. When brake light switch fails, the cruise control will not be shutoff by hitting brakes. If switch fails, hitting brakes will slow vechile, but cruise control will give it more gas. Date of initial accident is approximate since I do not have papers with me. Switch has failed twice since that and was failed after the accident.

What 1994 GMC Suburban owners say
Most recent owner complaints, unedited.
Front wiper motor stalled during rainstorm, travelling 55mph on major highway. Wiper and wiper fluid motor quit unexpectedly while in operation or while stopped. Sometimes a buzzing sound occurs with the failure. I discovered that I can tap the wiper motor module and the wiper motor may begin again, but its work will be shortlived. Another problem I encountered with this vehicle was a meltdown and small fire under the driverside dash. The rocker switch that controls the dome light has an "auto" and an "off" position. While in "auto" for about 1 hour with the doors open, I noticed smoke coming from underneath the dash and the rocker switch had melted down due to excessive heat building up in the contact. I contacted the local dealer when I purchased a replacement switch who commented that these switches were a problem.
April 26, 1996 original equipment battery failed, was replaced at superior pontiac, san antonio texas with a AC delco part 1981590. On july 30,1997 the ABS light on dash came on. Result of "acid from battery leaked onto speed sensor, shorting it out." had to have wiring and connectors, repairs to anti lock braking system, cables and paint replaced. I have all dealer paperwork that says all this in print. Was wittness to phone call at dealership about this same thing ahppening on mini van. Service manager said that AC delco has a big problem with leaking batteries and they refuse to take responsibility for it.
The battery is leaking onto the brake lines which could cause total brake failure. Please give any further details.
While driving vehicle stalls in traffic the car has electrical problems which cause the brakes /steering and headlights to go completly out.
For the last three years going to the beach,after two hours on the road the engine shuts down. Like you would just turn the ignition off!!! Wait a couple of minutes and it starts right back up. I just found on thecomplaints database search the very same problem that I have. It is odi id: 805983 and yes I am concerned that I'm going to get run over on the interstate!!! If gmc can't fix the problem, when should I have my lawyer file a suit? Right away??? Thank you very much, mr. Jack vaughn
