Full Answer
The repeated community answer is more nuanced than “yes” or “no.” Owners constantly say that mods do not act like a global “void warranty” switch, but in the real world, a tune, Accessport, intake, or other engine-power mod can make an engine/transmission claim an uphill battle. Cat-back exhausts, wheels, shifter parts, and cosmetic parts are generally viewed as low-risk from a warranty perspective, while anything that changes fueling, boost, torque, or airflow is where people expect resistance if something breaks. A second repeated theme is dealer variability: some dealers are mod-friendly, some are not, but the safe assumption in the community is that once you tune, you should expect much less warranty protection on the powertrain.
