[battlebeans]

My 2021 Model 3 recently started showing me this alert with a RCM2_a529 code. Anyone else seeing this on their end?

Not me, but don’t let that stop you from scheduling a service appointment.

hello, can you let me know what caused the RCM2_a529 on your M3? or how was it fixed?

I just had the same thing.
Mobile service came out and fixed it in 20 minutes…needed to replace a wire junction box under the front passenger seat.

Mine is out 3 weeks at Tesla waiting on the replacement module under the seat. Supply issues.

Concern: Customer states front left safety restraint system fault alerts keep coming up.
Inspected for left front restraint fault. Found a poor contact at the ground wire at the left drivers seat pretensioner. Removed the drivers seat and replaced the seat harness. Calibrated the seat and road tested. No alerts were displayed. Note there were no alerts on during the drive into the shop.
Correction: Harness - Seat - Driver (Remove and Replaced)
Total Charge: $526

I am waiting for another safety recall for this so that I can get my money back. This is my second wiring harness failure. First was my backup cam wiring harness failure which I got my money back through the recall.

I am having the SAME issues. Tesla Rockville gave me an estimate of $1300. Shouldn't this be covered under warranty? Plus no offer for a mobile, told me to bring the car in set for this Thursday. Any thoughts? Thanks all. Appreciate the dialog.

I've had that fault for months now and tomorrow a ranger is "supposed" to come by and take care of it... of course this will be the 4th reschedule by Tesla. Still, it's better than driving 140 miles to the nearest SC.

Weird. I’m in your area, and mobile came out and fixed it for me for free under warranty.

I'm 70 miles from the nearest SC and a ranger came by last Friday and replaced a wire harness that was causing my error message. It took about 2 hours to complete.
