Car won't go forward or reverse smoothly. It acts like a dead pedal then lurches. I traded pain with a safety barrier backing up when it suddenly went backwards. Also sometimes when entering the highway or passing a car it will go into limp mode. Can only be cleared by restarting car. Very dangerous.

The camshaft position sensors leak oil into wiring harness. The oil circulates to other engine sensors and the ECU(engine control computer). Oil in the other sensors and the ECU causes the car to stop operating or operate erratically while driving. a real problem. This is a safety issue there should not be oil leaking into the ECU! The mercedes dealer replaced the leaking camshaft position sensors and confirmed oil had leaked into the ECU and wiring harness on december 13,2021. They recommended replacing the wiring harness and ECU at cost of $6500. I have the replaced bad sensors. Mercedes says they have no culpability in this or a fix. The mercedes complaint number is #23264730932. The previous mercedes engine generation had the same problem and mercedes did a recall on that engine.

When starting the vehicle has a slow start. When in motion the vehicle drives rough, and cuts off, then the check engine light came on. This vehicle has a great maintenance record only serviced at the Mercedes dealer and has 0nly 54000 miles. This is clearly an engineering issue which was a safety issue. Mercedes repaired. They found the camshaft damaged, head damaged, and gear damaged and replaced camshaft and gear only. They charged my for their engineering failures $4874.38. For this engineering and safety faikure I believe this vehicle should be recalled before the lost health and life is lost, and owners should be recompense for the damage.

While driving on an express way in dallas, Texas my gps made an error concerning an exit and I was required to divert quickly to the left to make exit lane.time was 6:00 pm, heavy traffic conditions and road and weather conditions were excellent and dry. My Mercedes pre activated a skid mode and there was approximately a 70% cut back in engine power.a yellow engine light came on and skid mode came on operator screen but there was no skidding taking place. I was helpless with no power to keep up with the 50-60 mph traffic while trying to get into lane.consequently a semi tractor struck my left rear fender /bumper causing damage to my Mercedes. There was no damage to the tractor. According to Mercedes the vehicle was supposed to do this as a safety feature. If this is true then they actually in my opinion while developing safety features created another un safe condition where as the semi could have run over my wife and I killing us both. This was truly a near miss and we are very much concerned about it happening again to us or some one else, resulting in a fatal accident, not just a fender bender. Mercedes is in denial concerning any un safe condition and refused to take any responsibility for any damage that this car caused. Please review this vehicle for possible call back before some one does get seriously injured. Perhaps skid mode or traction control may be helpful but engine cut back and power loss needs to be left to the operator not the vehicle controlling it's self. Your help would be graciously appreciated.

Vehicle stops accelerating while driving. This has happened 4 times. At all other times, vehicle drives normally. Problem has occurred when accelerating after vehicle brakes have been applied to slow down. This is an automatic transmission and it seems that the car is not down shifting or the auto clutch is not engaging to allow down shift while accelerating. It drives like it's in 4th gear when it should be in 1st or 2nd gear if it were a manual transmission. There is a grinding sound as if the clutch was not pushed in fully while shifting if it were a manual transmission. At this point the car will only go about 10-15 mph until engine is turned off. When car is restarted, it runs normally. No check engine light comes on. Dealership states no fault codes were stored and they can not fix it unless they have a fault code or see it happen. They did road test it, but it didn't happen while they had the car. They did update the software to the transmission and hope that might fix the problem. I think this is a safety issue, because it happens without warning intermittently. I asked that they call the car engineers and ask what 3 -5 parts or sensors could be causing the problem and check to see if they are working properly, but they said no. They want me to try to drive to the dealership when it happens (not possible, no acceleration) or call for service and leave the car running until someone can get there to identify the problem. If a car or truck were coming up behind me or I was trying to merge onto a highway and this problem happened, I would not be able to accelerate and get out of the way.
