Consistently receiving 'passenger restraint system' warning indicating loss of airbag protection on onboard warning system. Dealership support notified several times while under manufacturer as well as purchased extended warrantees without any remedy. 'no fault' found by dealerships - reportedly their diagnostics indicated no current issue with passenger restraint system. Passenger restraint system continues to indicate shut-down while under normal driving conditions. Limited online research indicates that this is a persistent passenger safety control system issue specific to this manufacturer and model.
Pass restraint system error. Please help! I get this warning every so often when I get in my car and regardless of a passenger present or not. Several times the beeping signal will begin to make noise, to button the seat belt, even when nothing is in the seat. This is creating a very annoying driving experience.
Purchased used with 83,000 miles. Currently 100,000. The intermittently reports a failure in the passenger restraint system. When examined by a qualified mechanic, there is no indication of an issue with any of the passenger restraint systems. When this warning is present on the vehicle, I do not know what safety systems (if any) have been compromised. Dealership has stated there is a recall on similar vehicles during the same year, but not this vehicle even though it uses the same components.
