Seat belts
1 report
“The seat belt mechanism does not retract on the passenger side of my 2021 Porsche Boxster GTS 718. There was no warning and nothing happened to have caused this. This seat is hardly used as I am the sole driver of this. The seat belt was looked at by a body shop and dealer and we were warned it is an extremely unsafe to have someone in that seat . It does not work as designed and would be dangerous for someone in a short stop or accident etc. At just reached the 4 year mark from when I bought it, seems like a defect in the belt mechanism, according to car experts, as mentioned above .”
Back over prevention
1 report
“There is an intermittent problem where the backup camera fails to display an image when the gear selector is in Reverse. Backup camera reveals hazards that are not visible from the driver’s seat. Dealer has so far had three opportunities to diagnose the problem (and failed). Dealer was provided video of engaging reverse while the display failed to show an image. No other inspections were done. No other warnings, etc. I have had the car for 14 months and this (and other related) issues occurred sporadically during that time”
