   My 2018 Tesla Model 3 displayed alert RCM_a056, “Front Passenger Safety Restraint System Fault.” The warning may affect correct detection of a passenger and operation of the passenger restraint/airbag system.

   Front Passenger Safety Restraint error This seems to be a faulty component on many Teslas and therefore is a design or manufacturing flaw. Several of my personal vehicles of different models and years have had the same issue so it's not just something that has worn out or been damaged by myself. As this involves the action of the airbag, it is an extreme safety concern and Tesla should recall this part and replace. Also, in attempting a critical safety repair, I had to drive…

   The vehicle displays a critical 'Front Passenger Safety Restraint System Fault' warning on the dashboard, indicating that the airbag system may not function as designed in a crash. After googling the error code, it appears to be isolated to either frayed wiring harness under the seat or the faulty Occupant Classification System sensor. The issue occurred on June 11 and again on Aug 11 while driving the car. The warning appeared intermittently and I tried to "reset" the car…

    I have received a dashboard warning from Telsa that there is a “Front passenger safety relevant safety issue”. Upon follow-up with the Tesla service team, I’ve learned that the sensor has failed and since they can only replace it with a new and different type of sensor, they also need to replace the air bag. The initial cost was estimated at some $2,100. I bought the “2018” Tesla Model 3 in 2019. I’ve never had to replace an air bag in my some 40 years of owning a car. I…
