Started having problems with the hazard/brake light fuse blowing occasionally about 2.5 yr ago... Recently the fuse blows almost as soon as you turn the vehicle on. Bulbs are good and lights work until the fuse blows. I've replaced the electrical system in the steering column twice in that same period of time. The most recent time had no effect on the fuses blowing.
Check engine light kept coming on. The electrical harness caught fire in the engine compartment. Smoke was coming from under the hood in the driveway. Took vehicle to dealer. Was informed by mechanic the wires were installed too close to manifold. Had the wires replaced, but been having problems with wires every since.
Dt: one of the circuit board shorted out, and the vehicle will not start. Everytime starting the vehicle smoke comes out of the vehicle, and one can smell burning plastic. Saturday got the oil changed and didn't notice any problems.
Wiring harness failure. Causes truck to shut down when moving. Will not start. Had repaired ( rigged ) because the cost to replace this is in excess of 400 dollars, now is acting up again. Had to replace fan clutch as well.
Vehicle was parked & replaced oil. Noticed hood was black. Was informed that electrical wiring harness is too close to exhaust manifold. This caused the hood to burn. Took to dealer & had it repaired.
Engine speed will increase from idle to 2400 RPM without throttle input. This condition has occurred both when the vehicle is in motion and when the vehicle is stopped. When in motion, this condition creates a sudden acceleration problem. The only way for the driver to get engine control back from the computer (?) is to shut off engine and restart. This is an ongoing problem - for a year now - and occurs several times a week. I have taken the vehicle to the local Chevrolet dealership, but was told that they were unable to diagnose the problem because the engine check light light hadn't come on. I have also e-mailed Chevrolet about this problem several months ago, but have received no reply or acknowledgement. …
This battery has failed twice in 2 yrs. The battery terminals pull out leaking acid on cables and surrounding components and has also caused the alternator to fail. I saw a news brief in an auto publication that you had began looking into the problem on suburbans and tahoes. I have talked to other people who have had the same problem on other GM cars. I personally seen this happen on many GM cars with ac-delco batteries, I was an employee in a GM dealer for 21 years. I have contacted GM but have not received any assistance and this had happened over 2 months ago
Turn signals malfunctioned. The A/C stopped working due to a faulty evaporator. The stabilizer bar broke on right side which caused drift/pull. Engine coolant/antifreeze leaked. The ball joint for the right-front tire gave out. The alternator had to be fixed and replaced the battery. Speedometer seemed to be off by 5 MPH. The windshield wipers would not work properly and stopped in the middle of a down-pour. The device to lower the spare tire had to be replaced.
Speedometer sticks, almost every trip after a short duration (5-10 min). Also, tachometer occasionally sticks during extended drives 3hrs or more. In addition, instrument cluster replaced under warranty after first failure. Speedometer up to 15 MPH off. Forcefull tapping on instrument cluster will cause speedometer/tachometer needles to indicate current speed/RPM. Problem is independent of climate control temperature.
While driving 65mph vehicle stalled, losing power brakes and power steering. Driver turned ignition off and restarted the vehicle. Dealer said it needed a new control module. Dealer replaced vehicle cotnrol modudle at owner's expense. Consumer was informed by dealer that manufacturer is aware of problem and had issued a service bulletin (sb66-65-06) to replace the vehicle control module.
