What 1999 Mercedes Benz 420 owners say
Most recent owner complaints, unedited.
On 10/24, 2001, while driving mercedes s-420 with 65 miles per hour on pennsylavania turnpike, passanger side wheel with tire and wheel cap separated from the car and flew out to the opposite side of oncoming turnpike. After the car was towed to sun motor cars, inc. At 4444 carlisle pike, camp hill, pa,(717 737-3030) it was found out that the 4 bolts fixating the wheel to car were cut and sheared. And one hole was rusty. This might sugest that manufaturer used substandard bolts which could not withstand the pressure. I hope no other people had same experience leading to the injuries and death.
Strange electronic whirring sound when starting vehicle on 6/7. Side view mirrors suddenly moved and then closed halfway. No response from interior console control. Steering wheel also began to move up and down on its own. Rear brakes continued to squeak and grab. Were replaced under warranty last november.
Continuing idling and acceleration problems. On january 21, 2000, one month after second repair attempt, while driving vehicle it suddenly lost power then violently jolted forward causing temporary loss of control. (note: driver's foot did not touch accelerator). Driver then noticed "engine" check light suddenly come on (subsequently learned this indicates a fuel injection problem). Immediately notified dealer but problem persists. On april 26, "check engine" light again came on and car began to drive terribly, e.g., poor and inconsistent acceleration.
Transmission slips into neutral while driving. This has occurred 5 times in two weeks. It is currently at the dealer for repair of this defect, again.
