Turn Signal Error - Replaced BCM

[SteveFinn]

My Dad has an early 2018 JLUR with a whopping 10,000 miles on it. He is the original owner.

Last week he got a 'turn signals not working' or similar error. Hazards were also not functioning and I believe the reverse lights were out as well. Hopefully unrelated...but the only modification from stock are the oracle reverse lights that we installed 2 months ago.

Local Jeep dealer replaced the BCM to the tune of $500 (he has extended coverage so it cost him ~$100). The problem has been fixed...just wondering if anyone else has seen this.

Also, I tried to convince him that his original batteries could be the issue...I think he thought if that was the issue the Jeep dealer would address it.

I have just been in the process of fixing a jeep that had water damage including the bcm. With the bcm out I didn’t have any rear turn signals. None of the interior lights worked appropriately and the dash display was not functioning properly. There are quite a few circuits that pass through the bcm.
