Blind spot malfunction

[1STJ100]

So, interstate driving. Torrential rain. Noticed blind spot not functioning. Then intermittent. Then came on only when a car was alongside. (not behind). Ironically was driving to the dealership to pick up my plates. Have an appointment on 7/28. Will report back.

Do you still have issues when it's not raining?

The sensor is in the side of the taillight. It is only going to sense a vehicle on the side of you, not behind you.

Seems to be working again now that the weather has cleared

Since the weather is getting colder noticed BSM is temporarily unavailable every time rear window defroster is on, made an appointment for the dealership to figure this out.

Hey John,
I'm having this same exact issue...tried searching on the forums for similar issues and found lots of occurrences of blind spot monitoring temporarily not available, but not for the exact issue that I was having. Was the dealership able to figure it out? I've seen suggested solutions having to do with re-inserting the door connector, but I've also seen posts where the entire mirror was replaced.

Thanks,

Rich

Same happened to me this morning, ironically when I was on the way to the dealer. It was cold here and I don't actually think I've used the rear window heater until now, anyway the blind spot monitoring immediately errored and the orange triangle was on, just on the passenger side.
I suspect that this is due to the door harness pins alignment , as the side mirrors are heated when the rear is turned on.
I mentioned it to the dealer for the list of items to look at.

I had a a door pin that was misaligned on the driver's door that was causing the error light on the passenger side mirror. The dealership found the problem when I mentioned the orange triangle showing up when remote starting.

Sounds like a similar problem people are having once they remove the doors and re install them. the pins bevome misalign and cause blind spot errors and remote start as well. I have the same issue after reinstalling the doors.

It was the driver’s side door electrical connections. Someone more than likely at the dealership (I have yet to take them off) either had the door off or it came from the factory with a bent pin(s). The connection caused a short when the rear defroster came on and took out the BSM When I went for the first oil change and tire rotation I let the mechanic know the issue I was having, and he diagnosed the bent pin problem and I’m assuming just “unbent” it to make the proper connections. Everything is going great now especially with the Cold Weather Package.
On a side note; I got a fifth rim with Tire Pressure Monitoring System and am now able to rotate in the spare. The spare showed up with 41 PSI (dealership’s like to over-inflate it seems) compared the the average 39 PSI of the original 4. No issues with a 5th TPMS showing up, will update after the next tire rotation.
