Electronic Stability Control Problems of Mercedes Benz C320

Was driving on highway when esp, bas and abs lights show up, and speedometer display stops working - speed reading goes to zero, though there is no reduction in speed. Get to destination. On return it happens again. This time I go to rest area, stop the car, remove the key and restart. The car refuses to move out of park. Call roadside assistance and get instruction to override park, drive home with flashers on - very rough ride quality. Tow to dealer next day, they are not sure if new part will fix it, even if $1850 part is replaced. Lots of electrical problems over the years. Turn lights go out routinely. Changed cd changer. Seat drains battery,had to disconnect it. Poor electrical sensors all around. Now it also has rust damage, all of a sudden, at the bottom of doors.

At 55 mph the front left brake engages without applying the brake pedal and after a few seconds releases, the bas and esc faults are then visible on the dash. The brake light switch was replaced by mercedes two times, but this condition shows up after a few days of driving , codes show that the yaw rate sensor or connection is at fault. Even when the car is in park with the engine running on a flat level surface the fault warning dash lights esc and bas will come on with no movement in the car. This is a very dangerous situation for a collision from a vehical following me and running into me . Many others posted the same problem. Why is there no recall ? I have 8 grandchildren that you should care about.

Really dad experience problems with drivers and passenger side seat control modules draining battery when key off my car started on fire under the hood . !! two times.

Driving from san francisco (sea level) and eventually descending from echo pass at 7200 feet elev to lake tahoe (6200 feet elev) on hiway 50, all of a sudden, the vehicle display showed an esp warning light while simultaneously the engine went into 'idle' mode (engine was still running) and the accelerator pedal could summon no power. Pulled over and turned car off completely to ponder. Turned car back on and the esp warning light was gone. There was full accelerator power again. Continuing the drive into south lake tahoe, we experienced the same exact thing again two more times in only about 15 miles having to do the same restarting & clearing the esp warning to get to our destination. It continued to occur several more times in the 2 days we were at tahoe. We were worried about making it back to sf. We decided to try it and we left echo lake (7200 feet) and descended to sf (sea level) but the esp warning did not come on again at all for the next three weeks. Only last weekend, we headed back up to the exact same location at echo lake and behold, the esp warning came back on. By restarting the car and turning the steering wheel several times all the way left to right over and over, did the esp finally go out and we then drove all tyhe way home again to sf. The esp warning has since not come back on, nor has the car stopped or switched into an 'idle' mode. It is a nuisance and clearly electronic. . . . . . Faulty switches/sensors ?.

There have been two warning lights for rear lights and after drving for 4 hours, a warning came on for electrical stability and my car quit working completely. There was a burning smell and I had to restart it. I am very concerned about this.

While driving on a level and straight road the car automatically applied brakes and came to a complete halt. Weather conditions where; clear visibility, about 85 deg f, dry asphalt surface. Error codes resulting from this fault indicates a faulty esp yaw rate sensor. The independent mechanic code reader showed that the yaw rate sensor output was reading angle rates from as low as 34 to as high as 300+ gradients/sec, while the car was not moving and parked at the shop. As the person responsible for any actions while driving this car, I that the car should not overrule the driver's inputs and create an unsafe condition. The vehicle should just indicate to the driver the existence of an unsafe condition and do not take any action until the driver acknowledges this warning/caution.

Unpredictable application of esp in 2002 mercedes c-320 resulting in sudden and unpredictable braking and engine throttle down.

I have a 2004 mercedes C320 that incorrectly thought that it needed to cut power to the vehicle when I was turning to the left. It did this several times, I would guess about 6 or 7, from the time I left my house until I turned around and parked it in the garage less than 1/2 mile driving distance. These were not all complete left turns, most were curves to the left. My wife took it to the dealer later that day, and decided not to have it looked into because it did not do it to her and "the car was performing as designed" also she decided she did not want to pay for a diagnostic that would not produce any faults. It has not done it since, about 2 weeks now, but I continue to be concerned that it will recur in a more serious situation. The dealer keeps saying that the car is working properly because the warning light came on and the vehicle cut power as it should when it detects one of several conditions that would cause loss of control. The only problem with this is that there was no condition to cause loss of control. The tires were not about to spin and the yaw or whatever it is was normal. The dealer also keeps suggesting that I disengage the esc if I do not want it. I think this is irresponsible advise, the esc is a very important safety device that I do not really want to disengage, but I also do not want it to engage incorrectly in a critical situation.
