Recalls and investigations
3 recalls on the seats cover the 2020 model year. A recall on the same system isn't always the same failure, so read the defect text.

What owners wrote
“An error 'Front passenger safety restraint system fault' came up that seems to be a very common issue with someone people paying $1500 to nothing to fix.”
Filed May 12, 2024
“I have had an Alert notification, and reading through online, it seems there might be a consistent issue. Alert Notification: RCM_a056 Front passenger safety restraint system fault”
Filed May 8, 2024
“There is an issue with the front passenger restraint safety system. I got a warning that I need to replace the Occupant Classification System (OCS) of Front Passenger Seat due to faulty wiring.”
Filed Apr 26, 2024
“After receiving fault RCM_a094 I discovered that the seatbelt wiring harness had detached. When I took the vehicle in for repair, I was told it was caused by the wire being "tugged" on. Since I have never used the seatbelt in any capacity other than how it was intended, I believe this is a design flaw with the restraint system.”

Should you keep driving it?
This page can't tell you that. 0 of 33 reports involved a crash and 2 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.
