Is Your Porsche 911 Vibrating? It’s Probably A Loose Suspension Screw

Due to a software failure of the screwdriver on the assembly line, the screw connection on the rear upper control arm may not have been tightened to specification on certain Porsche 911s.

As a result, the German automaker is now conducting a recall in the United States of America, together with the National Highway Traffic Safety Administration.

In the affected sports cars, drivers could “notice noises or vibrations from the affected area”, the safety agency notes, adding that if the screw connection fails, then it could cause “sudden driving instability with significant changes of the driving behavior and the potential loss of controls”. Needless to say that such an issue would increase the risk of having an accident.

As Porsche corrected the fastening software on the assembly line in November 2019, only 7 units of the 911, including the 2019 Speedster, 2020 Carrera S Coupe, Carrera 4S Coupe and Carrera S Cabriolet are included in this safety recall. All of them are estimated to have the defect, so they will be thoroughly inspected by the company’s authorized technicians, who will tighten the screws to the correct specification. The recall is expected to begin on May 23.

Porsche 718 Cayman and Boxster recall

A second recall announced by the NHTSA concerns 190 units of the 2021 718 Cayman GTS 4.0, Cayman GT4, Boxster GTS 4.0 and Spyder. These engine connecting rods, which connect the pistons to the crankshaft, may crack and loosen, as they were not made according to specification, so they could damage the engine leading to stalling, power loss and oil leaks.

The planned dealer and owner notification is set for May 23, and that’s when the recall is expected to begin too. The fix will see technicians replace the connecting rods or even the entire engine in the affected vehicles, free of charge.
