2014 Mercedes-Benz Sprinter 3500 driver assistance problems

THE FOLLOWING HAS BEEN SENT TO MERCEDES CORPORATE CUSTOMER SERVICE All of the following has started happening since an exhaust recall was done by Mercedes. In September 2022, we were driving cross country to Denver Colorado and enough codes piled up in the background that we went into limp mode in the middle of 70 MPH highway traffic. This happened without warning and was an extreme safety concern. But I was lucky to be near an exit and already in the right lane. I reset these codes and finished going to Denver the next day. The two Sprinter dealers in Denver were backlogged several weeks; so we spent over $600 trying to troubleshoot the issues with Colorado Fleetworks, a qualified Sprinter specialist. He checked codes too; ran other diagnostics; replaced the fuel filter and air filter even though they had been done only 10,000 miles earlier; and performed a forced DPF regeneration. He also replaced the DPF pressure sensor. This work did not help change the daily multiple code problems. We had to reset them every day coming back from our trip. When we returned home we took it to the dealer. They confirmed the codes, reset them, and test drove it 25 miles. Since codes didn't return, they said, "There is nothing we can do if we don't witness active codes." I said, "How active do they have to be? I will have codes in the next 20 to 30 miles like I do every day I drive it." These never happened in the 6 years prior to the recall wok. Either the programming is confused, some of the new sensors are faulty, or something. A totally separate problem is the faulty factory crimps on the connector of the rail pressure sensor. This is a known defect; and we've had the exact same symptoms and code as noted in Xentry TSB MC-10135520-9999. The engine has actually cut off when turning into traffic a few times. This is an extreme safety concern.

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.

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!
