The ignition switch started to fail while driving. First the heater fan would quit and the ABS light would instantly turn on, and the cruise control would fail to operate. When the ABS light would be on the ABS would fail to operate. Then suddenly all operations would go back to normal. It would be unpredictable when the heater fan and the ABS would fail and come back. Then yesterday, the suburban started and died 3 seconds after starting. I restarted the suburban and all seemed good. I put the suburban in drive and rolled at about 5 MPH and the truck died. I stopped and put the suburban in to park and restarted. Placed it into drive and made it home. When I got home, I turned off the suburban and tried to restart it. It would crank but not fire the engine. The radio and heater and all other electronics would operate as normal, but the dash lights would not turn on I.e. The "service engine soon", "brake", "air bag", "ABS". The ignition switch has failed on it and now sits in my driveway.

What owners say
With the cruise control on I encountered sudden unintended acceleration on two occasions once while the unit was activated and once while it was not.
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.
Trottle to cruise control connecting rod was disconnected from the plate and fell down into throttle cable bracket. The hook on the rod got stuck in the bracket, holding the throttle open. The consumer was able to fix the problem.
While pulling up to a stop light, and applying the brakes, car shot into cruise control/gas pedal went to the floor and car was out control. Consumer had both feet on brake pedal, when car jumped into a ditch, and landed in a graveled parking lot. Consumer had to slam into park while feet were still on the brakes. Consumer took vehicle to dealer, and they said synchronizer was bad. Consumer felt this could have killed his family or innocent bystanders. *ak
Vehicle was moving on the interstate while at 65 MPH on cruise control. The automatic gear shift column was struck by the passenger and the transmission was sent into reverse. This action caused the brakes to lockup and the control mechanical lock on the wheel column was locked into a right hand turn with no way to control the vehicle. The vehilce started to skid out of control and then proceeded to roll over three times. All occupants were in saftey belts except my daughter who was int the back seat asleep. The vehicle was totally destroyed. It took resecue crews to remove myself the driver and daughter who was trapped in the back. We were transported via ambulance to a local hospital. All five passengers were released with only minor bruises and cuts. I would like to find out why the steering column lock and why a safety feature is not provided to keep the transmission from being accidently put into reverse while the vehicle is traveling in drive. Please help me find a solution to this potential problem.
Vehicle downshifts drastically, locks in a low gear and will not shift, ABS comes on prematurely, and the cruise control will not work.
Ea95-026 active, when brakes are applied, pedal goes to the floor, loss of brake effectiveness, also feels like the cruise control kicks in.
The cruise control would not disengage when hitting the brakes and the vehicle kept accelerating, causing an accident when vehicle went through a red light.
Abs brakes failed eight times, vehicle lost control, once resulting in an accident; also cruise control failed to disengage.
