MBM, please update about your running board. our RH is doing the same thing. sorry to here about your service issues, Ive gone to ford for oil changes now.
The RH running board on our 2020 Navigator developed an intermittent problem, at times it worked like it was supposed to, at other times it would come out halfway and then retract.
Our 2020 Nav has just over 6,000 miles.
As I mentioned, I asked our Lincoln Dealer to fix the running boards when we sent it to the dealership back in March for service, they said they were backed up and scheduled the running board repair 8 weeks later - which didn’t set well with me.
During the 8 weeks, the battery on the Nav failed and I went to the Lincoln Dealership to see if they would give me a replacement battery that I would install myself and then I would take the faulty battery to them. The Service Writer said he couldn’t do that and suggested I contact roadside assistance and have it towed to the dealership.
My local Ford Dealer allowed me to bring the old battery in and they tested it overnight and determined that it was faulty and they provided an exact Motorcraft replacement battery which I installed.
Still had running board issues and the erratic operation got worse until the RH running board stayed out.
The Lincoln Dealership came to pick it up for the repair and while the driver was at my house, the running board suddenly decided to retract!
After two days at the dealership the Service Writer called and said the issue was the battery not being fully charged and that was due to the fact that we don’t drive the vehicle enough!
He told me to drive it and that should fix the problem.
I don’t buy that at all because during 2020 and into 2021 we didn’t drive it much due to COVID and the running boards worked fine.
The dealership driver brought our Nav back and he handed me the repair order. I opened the passenger door and the running board came out approximately two inches and retracted. It did that same thing repeatedly. The driver took the Nav back to the dealership and that’s where we are at today.
I’ve owned 5 Ford Expeditions and three of them had retractable running boards and I never had a problem with those.
I believe there is some parasitic drain on the battery that is likely causing the problem.
