Airbag on other Model 3 years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2021, 2022, 2023, 2024, 2025, 2026.

What this problem usually is

Airbag complaints split into a few kinds. The most common is an airbag warning light that won't go out. Others involve the passenger seat sensor switching the passenger bag off with an adult sitting there, an airbag that didn't deploy in a crash, or one that went off without a crash at all. A large share also come from owners waiting on a recall part.

What owners wrote

“I have an active alert on the drive side safety restraint system. Alert code RCM_a021. I have noticed this appears to be a common problem. A recall should be issues as this a a safety issues and lives could be at stake.”

Filed Nov 26, 2025

“The "Front passenger safety restraint system" is prone to errors because the wiring for it beneath the seat is prone to getting knocked loose and electrical interference”

Filed Oct 19, 2025

“Airbag failed at 60k miles requiring a replacement. This is a known- safety issue, Tesla has corrected this problem in later cars, and Tesla should issue a recall to correct. I have error codes RCM_a015 and RCM_a014”

Filed Jan 5, 2024 · 60,000 miles

“Got an error code "RCM_a056" that indicates that there is a fault with the Front passenger safety restraint system. Looking at this problem online it seems that is not very unique and many owners of 2018 Model 3 have suffered the same issue. I was quoted for a service that changes the OCS sensor, but then they also have to replace the airbag due to "compatibility" reasons.”

Should you keep driving it?

This page can't tell you that. 15 of 142 reports involved a crash and 9 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
