In 2020, Volkswagen Group of America, Inc. extended the warranty on its transfer case for 2011 - 2018 Porsche Cayenne and Macan models. This was in response to what one article described as -??[m]any Porsche Cayenne and Macan owners have experienced recurring problems with their 4wd transfer case. We have the issues and the symptoms, such as vibrations under acceleration, highlighted in our common problems section.-?? Porsche and Audi share vehicle architecture for SUV models. In an April 2017 press release, Porsche touted the fact that Audi and Porsche share architecture with respect to the two brands-?? SUVs noting -??Audi, VW and Porsche have worked together successfully for many years in the area of SUVs, and with the new development cooperation, Porsche and Audi are positioning themselves for the next decade. In the coming months, joint teams will prepare the specific areas of cooperation and define the roadmap as far as 2025. The focus is on the joint development of shared vehicle architectures, modules and components.-?? My 2018 Audi experiences a -??jerk-?? during gear shifts feeling like an interruption during acceleration with a slight vibration. This jerky shifting is especially prominent when driving uphill. The issue persists today despite two service professionals trying to diagnose and correct the issue. I cannot speak to the safety risks this issue may present to myself and my passengers other than to say the -??jerking-?? and surprise hard-shift may cause passengers to react in an unsafe manner when traveling at high-speeds. I am submitting this matter as I believe the issue that existed with the Porsche SUVs that motivated Volkswagen, i.e., the Parent Company-??s, decision to extend the transfer case warranty, exists with the same model year Audis and may present a safety risk. More Audi-??s exist than Porsche models making it more expensive for Volkswagen to correct this for Audi. Correcting this for only high-end models and not lower-end is worth reviewing.
