FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:FUEL RAIL
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2016-2018 Jetta vehicles. The fuel rail bolts may become loose over time, allowing fuel to leak.
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:MASTER CYLINDER
Tenneco Automotive (Tenneco) is recalling certain Beck/Arnley Master Cylinders, part number 072-9831, sold as aftermarket or replacement parts for 2004-2018 Volkswagen Jetta, and 2012-2019 Volkswagen Beetle vehicles. The fluid seal crimp on the master cylinder may be insufficient, causing brake fluid to leak or the cylinder to come apart.
ELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:CONTROL MODULE
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2015-2019 GTI, 2015-2016 and 2018-2019 Golf, 2012-2019 Beetle and Beetle Convertible, 2017-2019 Golf SportWagen and 2011-2018 Jetta vehicles equipped with an automatic transmission, manual handbrake and keyless entry.

The EA888 2.0T TSI engine (Gen 1 and early Gen 2) is notorious for timing chain tensioner failure. The tensioner can fail, allowing the timing chain to skip teeth, which can cause catastrophic engine damage. This is most common on engines produced before 2013. Repairs typically run $1,200-$3,000. Severity: high.
The DSG (Direct Shift Gearbox) dual-clutch transmission can experience mechatronic unit failures, causing shifting problems, warning lights, and potential limp mode. The mechatronic unit controls the clutches and shifting electronically. Repairs typically run $500-$3,500. Severity: high.

The turbocharger can fail due to oil starvation, wastegate wear, or bearing failure. Wastegate rattle is common on IHI turbos used in earlier models. Turbo failure can send debris into the engine. Repairs typically run $800-$2,500. Severity: high.
The plastic water pump and thermostat housing are prone to cracking and leaking. The impeller inside the water pump can also degrade. This is a common failure point on the EA888 engine, often occurring between 60,000-100,000 miles. Repairs typically run $400-$1,200. Severity: medium.
Direct injection engines like the 2.0T TSI don't have fuel washing over the intake valves, leading to carbon buildup over time. This restricts airflow and causes performance issues. Typically becomes noticeable after 60,000-80,000 miles. Repairs typically run $400-$800. Severity: medium.
The PCV (Positive Crankcase Ventilation) system can fail, causing rough idle, oil leaks, and check engine lights. The diaphragm inside the valve cover can tear, leading to boost leaks and oil consumption. This is common on early TSI engines. Repairs typically run $200-$600. Severity: medium.
Jetta wipers commonly stop working because the linkage (wiper transmission) seizes, not because the motor dies. The two pivot shafts that carry the wiper arms run in bushings under the plastic cowl tray, where they are exposed to road salt and water; they rust solid over time. Th… Repairs typically run $200-$650. Severity: medium.
Sunroof-equipped Mk5 (2005-2010) and Mk6 (2011-2018) Jettas route roof-tray water down four small drain tubes inside the A- and C-pillars. The tubes clog with pollen, leaf litter and roof-sealant debris, and once blocked the tray overflows into the cabin. The front-left drain is… Repairs typically run $100-$1,500. Severity: medium.
The 1.8L turbocharged EA888 Gen3 (engine code CPKA/DAJB) fitted to the 2014-2018 Jetta consumes oil at a rate many owners consider a defect rather than normal. Reported rates cluster around a quart per 1,000 miles and worsen with mileage, with individual cars needing two quarts i… Repairs typically run $350-$6,000. Severity: medium.
The ignition coils on 2.0T engines can fail, causing misfires, rough running, and check engine lights. This is especially common on older coils and when using aftermarket spark plugs. High boost applications accelerate coil wear. Repairs typically run $100-$400. Severity: low.
