Front Passenger Safety Restraint System Faultâ, error message appeared. Tesla is asking for ~$1500 to fix a sensor that would prevent air bag from deploying. Seems like a safety issue that should be addressed. The message appears whenever there is someone/some thing in front passenger seat. Tesla has inspected. I believe it happened after a minor accident in a parking lot, but Tesla and the repair shop can not prove that it did, so insurance will not correlate to the accident.
