A formal letter sent to Porsche from members of the US-based Rennlist.com "991.1 GT3 Concerned Owners Group" about additional engine durability issues lead to a meeting between representatives of the owners group and Porsche, including head of Porsche Motorsport Dr. Frank-Steffen Walliser, on 3 August 2017 at the Porsche North America Atlanta headquarters. According to Dr. Walliser the concerning high-RPM misfire issue could be traced primarily to a metallurgical defect in certain batches of "finger followers" (valve train rocker arms) and secondarily to individual driving patterns and engine variations – such as temperature, oil quality, oil viscosity and parts tolerances – that lead to increased wear of the specific parts. In response to the issue and after implementing new engine tests to trace down the issue Porsche had developed revised camshafts and finger followers and offers a fully transferable 10-year, 120,000 mile extended engine warranty to all 991.1 generation GT3 owners worldwide that covers the replacement of the defective engine with a new engine with the revised parts if failure is a direct result of the finger-follower issue. The base bumper-to-bumper warranty and all other warranty terms and conditions remain unchanged. Porsche confirmed that the issue is isolated to the 991.1 GT3, and that the 991.1 GT3 RS and the 991 R are not affected.[39][40][41][42]
