2026 Volkswagen Jetta Problems
Owner-reported complaints filed with NHTSA, grouped by component

What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 Volkswagen Jetta, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The vehicle’s Forward Collision Avoidance system (Front Assist) and Automatic Emergency Braking (AEB) intermittently malfunction while driving. On at least three separate occasions during clear, dry weather with clean sensors, the AEB system engaged full hydraulic braking unexpectedly with no obstacles ahead—once while utilizing Adaptive Cruise Control and twice while driving manually. This severe "phantom braking" creates an immediate, life-threatening rear-end collision hazard on public roadways. Immediately following these braking events, the digital cluster displays the warning message "Front Assist Currently Unavailable."The vehicle has a documented history of electrical instability, including a prior dealership visit where technicians allegedly attempted to fix power errors by servicing a loose battery connection. However, electrical faults have persisted, culminating in instant, false "Engine is overheated. Safely stop the vehicle!" warnings within seconds of starting a cold engine, as well as non-functional rear seat heaters. These combined electrical faults align with an open powertrain ground failure, as described in NHTSA Recall 26V138 / VW Campaign 97TC (loose transmission ground wire causing stray current backfeed through sensor harnesses). The vehicle was towed to an authorized Volkswagen dealership on 09/14/2026 after displaying an instant cold overheating error and remains there for diagnostic inspection. The vehicle and its components remain intact and are available for inspection upon request.
The vehicle says it’s overheating and will go into limp mode it has also been reported that other 2026 Jettas have had the same issue

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.

Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
I'm not exactly sure on what happened but when using the lane stay assist it doesn't read the lines correctly causing the car to abruptly jerk in a unexpected direction! doing this during certain scenarios would cause an accident for sure. also the headlight auto switching for high beams malfunctions often causing the lights to flicker

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
