Reported at 200,000 miles, May 2016 CrashInjury

We own a mercedes benz c230. The check engine light came on. We took it to the dealer and it was diagnosed with a balance shaft error. It turns out the balance shaft is broken. The part cost only about $400. But since replacing it requires pulling out and taking a part the engine, the repair is over $3000. We have been advised not to drive the vehicle. It has not been repaired.

My first incidence was driving and the steering would all of a sudden get stiff like it needed power steering fluid or something. Check it wasn't the fluid (this happened a few month ago I thought hmmm probably just something freaky) then 1/8/16 riding down the busy interstate highway the car acceleration just left. I pressed the accelerator to the floor but no speed. It was extremely scary. I had the car checked out...it's the classic problem I never heard of until today.
