Most reported Volkswagen Jetta problems
One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.
Reverse gear failures and noise in the manual transmission models are common.
Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.
Condensation in the heater case may cause a musty odor from the heating, ventilation and AC (HVAC) system after sitting for two hours or more. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.
Heater core leaks are common in this model, more so if the wrong anti-freeze/coolant is used in the cooling system.
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
Fan assembly replaced. Dealer said there was a short in the electronics which led to fan not turning off after car was shut off.
Throttle body failure is not uncommon and can lead to shifting issues with the automatic transmission and other drivability concerns.
