2013 FOREST RIVER SOLERA Wheels Problems

completed emission modification work at dealer (OM624 Sprinter EMC#2). picked up car on June 18,2021. Took the car on a trip from Buffalo to Boston on June 21, when appx. 200 miles into the trip the Check engine, ESR, ABS and Skid warning lights came on. Lost cruise control. Pulled over and called the dealer. Was told that it looked like a wheel speed sensor problem. This is my third incident of speed sensor problems (two front and one rear). I understand there is a recall on the rear sensors only. I suggest that recall be expanded to ALL sensors. Also said recall is now over three month old and Mercedes still contends that there are no parts available and they have no ideas as to when they expect to start complying with the recall.
