2012 Volkswagen Jetta ProblemsDifficult to Diagnose Electrical Issues Are Typically Due to Ground Issues
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.
An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.
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.

2012 Volkswagen Jetta RecallsDriver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments
The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag inflator free of charge to resolve the concern.
The driver's side air bag may not be powered due to a loss of electrical connection from the clock spring sliding contact in the steering wheel caused by contamination. Dealers will repair the vehicle free of charge.
If a rear suspension trailing arm becomes bent, its durability may be compromised and it could break unexpectedly. If this were to occur vehicle control would be affected, increasing the risk of a crash. When parts become available, dealers will install a sheet metal inlay on each of the rear axle trailing arms to prevent sudden loss of vehicle control should a rear trailing arm suddenly break.
