Overview

2018 Porsche 911

The 2018 Porsche 911 continues the marque's legacy of performance and driver engagement. For the used car buyer, this model year presents a compelling, albeit complex, picture. While consumer complaints are notably absent, a significant recall concerning the airbag system and an unusually high number of Technical Service Bulletins (TSBs) suggest potential underlying quality concerns. Buyers should prioritize verifying recall completion and understanding the implications of the numerous TSBs.

Critical Failure Risk

A recall (19V179000) addressed improperly tightened side air bag impact sensors. While the recall remedy is straightforward, any residual issue could lead to non-deployment or improper deployment.

Early detection can help you avoid a $500-$1,500 repair.
