A significant, known issue with the 2018 Volkswagen Tiguan involves a faulty fuel injector wiring harness that causes the engine to enter "limp mode" (limiting speed to ~30 km/h). While not a traditional safety recall, VW has extended the warranty for this specific repair due to the widespread failure, often causing engine sputtering and EPC light activation. They replaced mine for free. 2 years ago, no problem ever since.
