“The vehicle on board video entertainment display has stopped working properly. It does not allow any input to the touch screen. And the only way to regain some functionality is by pressing the steering wheel source button. However it works intermittently. And this causes Driver Distraction while driving.”
“Following an engine-out service at an authorized dealer (Bill Kolb Jr. Subaru), a primary powertrain mounting bolt was left unthreaded by approximately 1 inch, creating an undetected 8,000-mile safety hazard that resulted in extensive drivetrain and suspension component failures. Subsequently, during a diagnostic inspection at another authorized dealer (All American Subaru), heavy rusted metal pliers and loose cowl trim panels were abandoned unsecured inside the wiper cowl tray beneath the windshield, posing a severe roadway projectile and steering/wiper obstruction hazard.”
“My wife experienced an unintended acceleration in her 2018 Subaru Legacy. My wife had begun to slowly back out of a parking space in a school parking lot when her 2018 Legacy went into an unintended rapid acceleration in reverse. The car took off in reverse and did not respond to her applying the brakes. Somehow she managed to steer the car which was rapidly acceleration in reverse, virtually uncontrollable, and guide the car down a row of parked cars until she clipped the front of another car at the end of the row and her car came to a stop. Thank God there were no students in the parking lot at the time! The floor mats in our Legacy are Subaru mats that lie flat and in no way would affect the accelerator pedal. As the car was accelerating in reverse, and she had removed her foot from the accelerator onto the brake, the brakes did not slow the car. There is considerable damage to the right rear of the car and trunk. After the accident, when the car was restarted, the accelerator and brakes worked fine and she was able to drive it home from the scene. Thank god students were not in the parking lot!
