2003 Chevrolet Express Owner Comments

problem #3

Nov 012013


  • 36,000 miles


I was traveling on the highway at the speed of 50 mph and the van suddenly began to violently shake and shudder from the front wheels and up and including the shake of the steering wheel. I slowed the vehicle down by braking to 35 mph and it slowly stopped shaking. This has become a regular issue with the vehicle and I have taken it from shop to shop and mechanics cannot figure out the problem. I fear for my family's safety as well as my own when driving alone in this vehicle. It has been a year since this has begun. Mechanic has changed the shocks for the van and it has began to violently shake and shudder more frequently. I need to know why this is happening. I own a Chevrolet Express 2500 (2003).

Driving on interstate at 65 mph, the ABS warning light came on, and the speedometer started jumping erratically from actual speed to lower speeds 45, 25 + others as low as 8 (eight) mph. This caused the transmission to downshift unpredictably, over-revving the engine speed. It happened repeatedly so I documented the odometer erratic movement on my cell phone as a video, showing road movement + all gauges + audio events like engine over-revving at same time. The video is of high quality and the events taking place are documented with the video. Rural area with few cars on road at the time. If it took place in a city interstate environment (especially in the winter months) it might have caused a multiple car collision with sudden unexpected downshifting that was out of my control. Engine RPM also hunts erratically and out of my control. Predictable in what it does, it begins approximately within a range of 4-8 miles after leaving home daily. When engine turned off and parked at a local store as an example, it will clear it's problem as if a cpu is "re-booted", and repeat the cycle of erratic behavior from that new starting point. When I bought + installed actron brand obd-II code reader which features ability to reveal ABS brake codes, it never shows any other stored codes except a single PO446 which is an emissions related code. This van was originally sent new by the selling nh Chevrolet dealer to the Pennsylvania based quigley conversion facility, so in February 2004 was modified from rwd to a 4WD by exchanging stock model 2500 front end for a 4 wd pickup truck new factory front end with 4wdl, neutral, 2wdh 4wdh floor control lever. The driver's door jam has an 8600 lb gvw certification which is appropriately quigley's. my very low odometer at 16,614 miles is accurate, as I also have other vehicles to use, and work at home.

Driver a noticed lack of pressure in brake pedal. The brake pedal went fully to the floor and resulted in less braking than expected. Driver reduced speed by downshifting to lower gears (automatic transmission) and pulled into first available parking area. By pumping the brakes and pulling into an uphill parking spot, driver achieved enough braking to come to a full stop without using the emergency brake. Inspection showed a nearly full brake reservoir and no leakage from wheel cylinders. Further inspection showed leaking fluid from brake line on left side under the drivers seat and above the vehicle frame. It squirted out from a crack in a brake line when brake pedal was pumped. The vehicle was deemed unsafe to drive. The vehicle was towed for repair.
