ATLANTA – Porsche Cars North America (PCNA) has agreed to recall certain model-year 2022-2023 Porsche 911 GT3 Touring vehicles due to a potential malfunctioning Center High Mounted Stop Lamp (CHMSL) system.
The 700 sports cars within the recall population have dual CHMSLs because a moveable rear spoiler, which deploys at speeds of 90 km/h (55.9 mph), would block the primary one. In addition, the driver can manually deploy the spoiler at lesser speeds which can lead to the safety issue – in such cases the two CHMSLs would operate in tandem.
According to the National Highway Traffic Safety Administration’s Part 573 Safety Recall Report 23V-446, “Simultaneous activation of two CHMSLs may be confusing to operators of vehicles behind the subject vehicle which may increase the risk of rear-end crashes.”
The root of the problem, according to the NHTSA report, is a software error in the rear-spoiler control of these cars produced between Jan. 12, 2022, and May 25, 2023.
The remedy is reprogramming at a certified PCNA dealer of the rear-spoiler control unit with a new data set.
There were no reports of crashes or injuries related to the issue covered by the recall.
Dealers were scheduled to be notified of the Porsche safety recall by July 3rd; owners are scheduled to be notified by Aug. 24th.
