I was driving on the highway during rain and 3 messages displayed on the dash: 1) esp (electronic stability program) visit workshop, 2) asr (acceleration slip regulation) icon visit workshop and 3) ABS (anti-lock braking system) visit workshop. Also received collision avoidance assist inoperative notification. I pulled off the highway and experienced unexpected acceleration and erratic gear shifting resulting in extremely unsafe operation. Later, mercedes service determined the left rear wheel speed sensor was the problem (see attached). Diagnosis and fix was $473.99 plus tax. They said this is a common problem with sprinters especially if uplifted to rv. I understand there is an ongoing the federal safety agency investigation of this problem. I strongly believe these wheel speed sensors should be recalled due to their effect on esp, asr, ABS and collision avoidance assist causing unexpected acceleration and erratic gear shifting which results in extremely unsafe operation.

While driving on interstate highway, the following warning messages appeared: ABS, esp and ars not functioning and take to workshop. Also, the blindspot warning on mirrors stopped working, as did the cruise control. Drove several hours to nearest mercedes dealership without these safety features. Problem diagnosed as RPM sensor failure. Was advised that although only one sensor failed, they recommended replacing both at the same time. At the time, the vehicle only had 40,111 miles on odometer, but was not covered under warranty. Service advisor stated that sensor may have gotten hot, suggesting I had driven with emergency brake on. I took exception to this, as I rarely employ the e-brake unless I am on a very steep incline, and had not used during this trip. Repair cost totaled over $700. Copy of bill attached. This occurred on september 8, 2018, as I was beginning a multi-state trip.

While driving about 30 miles per hour on a slightly bumpy road, three indicator lights on the dashboard started to show problems with the ABS, asr/bas, and ebd systems. According to the onboard diagnostics the root problem is a faulty right rear wheel speed sensor. This design seems to have put the wheel speed sensor in a dangerous position exposed to the elements, which causes it to degrade and stop working at a high rate.

Vehicle has had two speed sensors replaced, first one is the left rear at only 10,385 miles may 29th 2020. The second one on the right rear at 10,615 miles july 8th 2020. Dealers are aware of the sprinters having this issue yet there have been no recalls on this. As of this date total cost to get it operating safely again is $1018.93 ( parts and labor ) when these go out there is no warning while you are driving down the road which you then lose your ABS braking, traction control and stability control. After investigating this it is a known fact and has been for years. This is a very serious safety issue and not any technician can replace this. All this happens while in motion city driving and highway driving.

At highway speed the vehicle suddenly shifted down and I noticed 3 yellow warning lights: ABS, esp, asr/bas. Fortunately, I was able to pull over. I phoned a mercedes dealer and was told it sounded like a faulty wheel speed sensor and that it was ok to drive with caution. A authorized sprinter repair center did diagnose the rear wheel speed sensor. $345.00 later the problem is fixed. The service manager said they see a lot of these. He said that the replacement sensor has a new part number which tells him that it has probably been improved. I hope so!

On: city street, in stop and go traffic. Upon pulling off from a dead stop, the vehicle began jerking, then accelerating uncontrollably. I could not slow the vehicle with the brakes. If I had not moved the gear selector to neutral, I would have hit the car in front of me. Abs, anti-skid, and traction warning lights came on, and I barely had enough power to pull off to a safe place. After sitting a few minutes, I was able to drive the vehicle safely to the dealer. Dealer replaced right rear wheel speed sensor under warranty with what they called an "improved part", but there are three more speed sensors. *dt
