Seat restraint malfunction that prevents the air bag from working properly. Dealer is aware of this problem but has not been able to correct it.
Vehicle is relatively new and kept in great shape. No damage nothing, one day the sensor for passenger airbag malfunction appears indicating that passenger airbag will not deploy in event of a crash. Dealership says it’s not covered under warranty and have to pay to replace out of pocket costing multiple thousands of dollars. Error seems manufacturer defect.
Had a passenger restraint system malfunction error warning light. Took the car to the dealer for service and they replaced the air bag repair wiring harness from the ACSM (air bag control unit) control module to both knee air bags. This did not fix the error, so they then replaced the air bag control unit. Error message is now not present. Dealer stated air bags would not deploy unless I had the repairs done, yet they stated that this safety issue was not covered by my warranty. Car is 2019 model with less than 20,000 miles.
