I have a 2021 Bronco Sport with 68k miles. I had the RDU issue a few months ago and they replaced the vent and drained/replaced the fluid. Now the grinding noise appears to be back on hard left turns driving in a circle. Also I am getting a bunch of warning lights, ABS, traction control, etc... Has anyone else seen these warnings coincident with the RDU failure? Thanks.

I did have the same issue with only 20,000 KMS. They replace the fluid first and everything seemed fine for a couple of days. Then had issues such as no goat modes, and other aids disabled. They replaced the RDU motor since there is a Ford Service bulletin for this issue. Car now has 37,000 kms without the RDU issues, knocking on wood.
