Both my rear break lights are showing stress cracks from movement of the frame of the body. There are other references to this happening online from other owners and it's a manufacturer defect. I brought to the dealer and was told that they should be replaced for $3000 each as they are allowing water to intrude and will cause a shorting out of the brake lights. No brake lights would be a major hazard. The cracks in both lights were not due to impacts. It is a design issue.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Porsche 911 Targa 4s Heritage Edition verdict →
