RENNtech Extended Protection Plan


RENNtech Extended Protection Plan Eliminates Factory Warranty Worries after Performance Tuning


RENNtech Mercedes, AMG, Aston Martin, and Sprinter tuning enthusiasts protect their investment with our Extended Protection Plan, and don’t worry that a dealer may deny factory warranty claims due to RENNtech performance upgrades. This transferrable, comprehensive service contract covers powertrain repairs for the duration of the factory 48-month/50,000-mile warranty after installation of our HHT, Stage I Turbo, or Stage II Turbo if Mercedes-Benz USA or its dealer denies warranty repairs due to these aftermarket modifications.*


Save money by purchasing a RENNtech Extended Protection Plan during the first 30 days of product purchase. You may purchase a plan later, but there will be a surcharge. The RENNtech Extended Protection Plan is only available for select Mercedes-Benz, Sprinter, and Aston Martin models. See if your vehicle qualifies and get a personalized quote now.




Does installation of RENNtech aftermarket parts and performance tuning void a factory warranty?


RENNtech is the tuning choice of Mercedes-Benz Dealerships who install and service our products, and work with RENNtech directly should the need for warranty service arise. We're so confident in the quality of our RENNtech products that they come with a 24-month Limited Product Warranty that guarantees our products are free of defects in material and workmanship and covers repair or replacement of the part.**


While the Magnuson-Moss Warranty Act is meant to protect consumers, it is not a guarantee that any auto manufacturer or dealer honors your factory warranty. There are reported instances of auto manufacturers stating that tuning and aftermarket parts void the factory warranty and flagging the vehicle on the entire system of its dealers' computers to deny warranty repairs to the powertrain. Disputes are a time-consuming hassle and often require an attorney to compel manufacturer compliance.


That is why selecting a reputable company, with quality parts you trust, to install upgrades and service your Mercedes-Benz, AMG, Aston Martin, or Sprinter is essential when choosing an aftermarket tuner. Performance enthusiasts with a RENNtech HHT, Stage I Turbo, or Stage II Turbo and our Extended Protection Plan are not at the mercy of the manufacturer’s warranty repair determination.


The RENNtech Extended Protection Plan is only available with the purchase of RENNtech products and allows you to focus on performance, while we handle protection.
