Three problems related to power train have been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
The contact owns a 2004 Chevrolet Silverado. The contact stated that after parking and exiting the vehicle, she heard an abnormal clicking noise as the vehicle started to roll away in reverse. While attempting to stop the vehicle, the driver's door opened and slammed her to the ground, traveling over both of her legs. The vehicle then crashed into a fence. A police report was filed. The contact sustained damage to the nerves and arteries of her legs. The vehicle was destroyed. The manufacturer was not made aware of the failure. The failure and current mileage was 154,000.
My vehicle is a 2004 Chevrolet Silverado k2500 ext lwb 4wd with approximately 21,000 miles. I have used the four wheel drive feature off and on as needed to negotiate slick road conditions without any problems prior to this incident, which occurred on 12/23/08: while driving in four wheel drive, high range, at approximately 20 mph on an ice covered road the front wheels locked up without warning, causing me to lose control and skid off the road. Had I been going faster, or if I had been in a traffic situation, there could have been a serious accident, possibly resulting in injuries or death. This front wheel lock up condition is still present as long as the four wheel drive selector is in either high or low range. In two wheel drive the problem is not evident. I have made an appointment with the selling dealer to diagnose the problem, but as yet I do not know the root cause of this malfunction. Although this incident was a near miss, I am reporting it because of the serious nature and the hope that a safety recall may be issued so that other accidents may be avoided.
The contact owns a 2004 Chevrolet Silverado. The contact stated that while driving 70 mph, the reduced engine power warning message illuminated as the vehicle decelerated to 15 mph. The contact depressed the accelerator pedal all the way to the floorboard but the vehicle would not accelerate. The failure recurred intermittently through out the years and the dealer replaced the electrical harness, the throttle grounding wire, throttle body and the fuel cap, but to no avail. The dealer could not diagnose the problem. The manufacturer was notified of the problem. The vehicle was not repaired. The approximate failure mileage was 200,000.
