2021 Ford Explorer •Problem: Blind Spot Detection / Sensor Malfunction •Description to copLeft-side blind spot sensor fails intermittently. It shows no warning when vehicles are in the blind spot, creating a risk during lane changes. I found Ford TSB 23-2048 confirms the issue. Dealer quoted $1,200 but this is a known factory problem and safety issue.

The back up camera fails basically 1 out of 5 times it's engaged between skipping or just straight blue/black screen. The screen is out and causes blind spots while backing up.

All of the sensors are out. Nothing is working. They were working fine then one day I noticed the lane keeping sensors were not working. Today I noticed the side sensors are not working which they were this morning. The middle row seat gets stuck if moved forward, it will not stay back. The button is always stuck so while on the road the seat randomly pops out of place. The wipers do not work properly, only on high speed. I have already called McCombs Ford West in San Antonio, Tx as I purchased the vehicle there in October of 2021 but they are not worried about it. They said I can go drop it off but they will check it when they get a chance and will not provide a loan car which I cannot do that as I have kids. All the safety features that it should have are not working. They told me it would be weeks before they even look at the vehicle.
