While the auto industry reels from massive recall after massive recall, Porsche has quietly been working on a fix for an issue that’s forced owners of the new 911 GT3 to park their track-ready rockets for fear of an engine fire. Thanks to a leaked letter from Porsche to a GT3 owner (which has been certified as real), we now have an idea of just where the German brand is at with the fix.

On April 22, Porsche will begin production of a new batch of GT3 engines for the 785 affected models across the globe. As you’ll recall, the original issue rested with a screw joint that could loosen the connecting rod. The new engines have an “optimized piston rod screw connection,” that should keep the connecting rod in place. Once technical validations are completed, production will kick off and new powerplants will be shipped around the globe for owners of the troubled cars.

Porsche will hand out a certificate to owners of affected cars once repairs have been completed, as a means of documenting the work. To make up for the trouble, Porsche will be giving owners an extra year on their new-vehicle warranty, while the 911 GT3 concierge will be reaching out to compensate them for having to park their car for so long.
