The 2021 Porsche Cayenne GTS has two recalls, the more serious being an engine cylinder bore that can develop cracks, leading to engine damage, a stall, or an oil leak that raises the risk of a crash or fire.
The second recall involves the front passenger seat's occupant classification system, which detects whether an adult is seated and determines whether the airbag should deploy. A missing seat back heating element can throw off the system's calibration, causing the front passenger airbag to fail to deploy in a crash.
