 I was driving down the highway at normal posted speeds (65 mph) and my engine all the sudden cut out. it stumbled and died. i had it towed by l&a wrecking company to the shop. turns out it was the valve springs the failed (apparently very common with corvettes) and almost caused a huge wreck due to me having no power.

 As i was driving, coasting my car down a hill in buffalo, ny my 2002 chevrolet z06's motor shut down completely. i was making a right-hand turn when the vehicle lost all power-assisted steering and the vehicle could not be re-started. i later found out from the dealer where i had my car towed that my z06 had broken a valve spring in its engine. after some research, this appears to be a common problem with 2001 and 2002 corvette z06 models made by chevrolet. there are many examples nearly identical to mine where the vehicle's valve springs will snap and prevent the valves in the motor from operating successfully and thus preventing the car from moving under its own power. i believe this frequent problem is a safety hazard as many of these failures occur while the vehicles are being driven on public roads and are rendered inoperable by the failure. moreover, after one of these valve springs breaks, the car loses its power steering function (that most drivers are accustomed to having in assisting their steering at low speeds); the function a driver would need most in an emergency situation where their car cannot maintain speed on a public roadway.

 I have a 2002 chevrolet corvette that is in for repair for abs and other. the part a abs module does not seem to be available and may not be for another 2 to three weeks. this car has been in since 5/5 and i have no idea when i may get the vehicle back. i do not think it is reasonable to have a vehicle in for such a long time. the vehicle uses a lot of oil also, and engine noise is a problem. *nlm

 The engine emits a bird like churping noise irregardless if the vehicle is moving or idle. possible getting louder over time. chevrolet has known about this since 2/1/02. still no fix. i call every 2-4 wks & receive the same story the engineers are working on it. is this dangerous? totally frustrated.*ak
