Two problems related to brake sensor have been reported for the 2019 Volkswagen Jetta. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2019 Volkswagen Jetta based on all problems reported for the 2019 Jetta.
Metal plates in the road trigger the the car's front-assist sensor to activate the autonomous emergency braking system in the vehicle, despite the absence of any obstruction. The result is a jarring deceleration from ~20mph to a complete stop in a matter of feet: effectively minor accident. There is no advanced warning, only a simultaneous buzzer and dashboard signal. It poses a significant risk to all vehicle occupants, especially passengers who are unaware of the hazard or otherwise unable to prepare themselves (e. G. Infants). This problem is persistent, disruptive, and dangerous for the vehicle's occupants as well as any trailing vehicles that may consequently crash into the unexpectedly halted vehicle. Volkswagen claims that this is "expected behavior" of the sensor, as the vehicle manual warns of "unwanted" behavior when "there are . . . Metal plates in the road. " nevertheless, while it may be "expected," it is still patently unsafe. Volkswagen's suggested resolution is to permanently disengage the front-assist safety feature of the vehicle. This is unacceptable because it exposes the vehicle's occupants to other safety hazards that might otherwise be avoided with an engaged front-assist system. Furthermore, the system must be disengaged anew on each vehicle restart, which leaves room for potential operator oversight. I experienced this unsafe behavior nearly daily for almost 18 months due to construction in my neighborhood, and I have documented it 3 times with timestamped videos. As this site does not permit video files to be uploaded, I can provide those upon request. A bbb auto line case was opened again Volkswagen. Vehicle repurchase was denied based on Volkswagen's warning of "unwanted" behavior in the vehicle manual. Nevertheless, the decision affirmed that "the front assist issue substantially impairs the use, value and safety of the vehicle. ".
Vehicle proximity sensors began to flash, despite being the only car in a freeway entry lane. There were no cars in front of me, or in back of me, but my vehicle's sensors began to flash and the car began to break as if preparing for a collision. Car never stopped completely, since my foot was on the gas. Sensors continued to flash on dashboard for a minute. I'm not sure of what causes this, perhaps the equipped vehicle software isn't clear of bugs, or sensors could have been manipulated via bluetooth connection.
