2020 Volkswagen Jetta Engine Problems

When you start your car, all the dashboard lights come on and the car acts like the engine is running, but the engine doesn't actually turn over when you shift into gear. You have to press the ignition button a second time to get the engine to actually start. This likely involves a problem with the starter motor or the ignition/starting system that prevents the engine from cranking on the first attempt.

Your engine's EPC warning light came on without prior warning, indicating a seized wastegate in your turbo. The dealership quoted $4,026.85 to repair it and noted a wait for parts. If the light had been flashing, your car could have bucked and stalled in traffic, creating a serious safety hazard.

Your check engine light came on, and diagnostic testing revealed a faulty vent control valve—a part Volkswagen acknowledges has a known failure pattern but won't warranty after 60,000 miles. You'll need to replace this valve (around $250) plus pay for labor (around $200), and Volkswagen dealers charge an additional $238 just to diagnose the problem. Over 11,000 vehicles are reportedly affected by this same issue.

Your engine has shut off unexpectedly while driving at highway speeds (55 mph and 45 mph), with warning lights appearing on your dashboard. The first time it happened, you were able to restart the vehicle and drive home, but the second time required several restart attempts. Your dealer ran diagnostics but found no defect, and the vehicle has not been repaired despite multiple service requests.
