2021 Newmar Bay Star: ABS light or ABS activating

Filed May 22, 2025 · Wheels · MD

Wheel bearings and hubs failed on both front wheels of our RV. Our current mileage is 38500. According to maintenance service is not required on the bearings until 60,000 miles. At that time bearings are to be regreased. At 150,000 miles bearings are to be replaced. The mechanic that did the repair work informed us that we were lucky the front passenger wheel didn't fall off. I understand that the Ford F53 chassis has encountered this wheel bearing issue. We have filed a complaint with Ford with pictures and detailed information of the work that was done to both of the front wheels. The only indication we had of this issue was intermittent vibration in the front end (as if you were riding over a rumble strip). Also, the ABS light came on and then went off. We were driving from Maryland to Texas and on the last day of our trip about 100 miles from our destination is when the vibration first occurred. Upon arrival we tried to contact Ford dealerships in the Abilene, Texas area. None of the dealerships contacted would service our RV. We then contacted an independent truck repair shop who diagnosed and fixed our RV. Total cost was just under $8,900. The parts were very difficult to find from Ford. Ford said that many of the parts needed were on back order and wouldn't be available for more than a month. According to the maintenance schedule this issue should not have happened. We feel there is a major issue with the Ford F53 chassis wheel bearings and a recall should be issued by Ford due to the dangerous conditions it creates.

It all started with the advance traction control. Driving down the highway with wind gust disabilies the cruise control and then the ABS. This continued to happen. Your have to pull over and turn off the rv to reset the ABS. On the long trip we were pulling over about every 10 to 15 minutes to reset the system. We took our ford v8 rv into shop for repair. After having the repair done. We took a trip and immediately it happened again. It was not fixed. We were told this problem is not fixable from ford after spending $581 for nothing. And told it was not under warranty. Purchased in june 30 2021. We believe this is a main problem due to your speed and the cruise control kicking off the ABS, disabling the ABS, especialy in traffic. Newmar and ford, both do not want to take responsilibity and we are left hanging with this problem. We have come to believe that this is a problem with all 2021 or older v53 chassic on rv's that does not have a fix on numerous rv manufacturers. Everyone that uses that platform

New 2021 newmar bay star, which has a 2020 ford f53 chassis. While driving on the freeway the service advancetrac warning appeared on dash along with amber warning light. This disables traction control system including cruise control, hill assist and maybe ABS. Problem has yet to be diagnosed/resolved.
