My 10/28 Build also does this sporadically.

I got this for the first time after 7 weeks of ownership. " front right parking sensor blocked". It is interesting that it started happening after I had a car wash in the afternoon, then temps dropped to 16f overnight. Wondering if ice built up around the inside of the sensor. Parking in a warm work garage to see if it dries it out.

I traded my 22 Lariat SR for a 23 Lariat ER and had this exact problem. After 1 week it was occurring regularly so I brought it in for service. They said they found one of the sensors was "pushed in" which was causing the error. No errors since they made the repair.

I do have another issue with the module that controls vehicle location, but they couldn’t replace that as it is on backorder with no release date.

How did you make out on that trade up to a ER?
How many real world miles did you gain?

I made out well on the trade up. My dealer was great to work with. I knew that I really wanted the ER as I had one originally that was totaled when a driver decided to run a red light. To answer your question I'm seeing about an addtional 100 miles vs the SR.

Turned mine back on after having it off for a couple days and haven't gotten the error again. Seems like it was related to the heavy rains we were having? Maybe?

Well, I’m dropping mine off at the dealership next week. The sensor error has been happening intermittently multiple times per day, or every other day, for about week. No rain perfect weather (high in the mid 70’s) lows in the 60’s
I don’t yet have 1,000 miles on it, and just want it fixed. Another weird issue- it overheated after starting and sitting in the driveway for about 1 minute. It’s only done that once. This truck is more computer than truck. It works. It doesn’t work. It has an error- one second later everything’s great.
Love the truck but the issues are adding up

I had this issue and one where when backing up it would think there’s an obstruction on my passage side and beep at me like crazy when there is nothing besides me. Dealer looked at it and says it’s a faulty module.

Apparently the truck keeps a log so they could see when the alerts triggered. They ordered a new module but naturally no idea when they’ll actually get it, just like the light bar on the hood that needs to be replaced!

Please keep us updated on the fix. I’ve had my truck for two months (~2,000 miles) and the dealer has already replaced the rear driver sensor because they stated that was the issue. However, I still get the ‘Parking sensor blocked’ error every other day and it isn’t consistent (morning, night, sun, rain).
The last time I brought it back to the dealer they told me they couldn’t replicate the error, so it’s good to know they can actually look at a log. If you can tell me what module they are replacing then I can pester my dealer for the same fix.
I absolutely love my truck, but I also agree that these new vehicles are more computer than truck.

Anyone having this issue that post on your dashboard every 3-5 minutes? I was told that an update would correct it come the new year.

This happened to me during a slush/ice storm a few weeks ago. I stopped, got out of the truck and wiped off the round radar sensors on the front bumper. The problem went away.

A couple of weeks ago I washed my truck with the pressure washer. That same day my rear bumper sensors gave me a warning that they were blocked. The next day the issue cleared up. We had a wicked storm roll through Atlanta this morning and on my way home from work I now get front and rear sensors blocked and a speed sign recognition not available. Anyone else run into this?

Sounds like many of the sensor alerts are just from defective sensors. OTH, the owner's manual specifically advises against pressure washing the truck cameras and sensors:

Thanks. Seems like they dried out overnight and now fully functional for my commute. I dont understand why my 2021 F150 did not have problems with this but the Lightning does. As for the pressure washing, yes I avoid the sensors and cameras.

Or maybe its the IPMA update you haven't gotten yet? My sensor warning hasn't gone off since I did the update with FDRS last week. It might go off again, dunno...but so far it hasn't.
