While traveling on highway, parking brake intermittently activated several times and parking brake malfunction alarm flashed on dashboard. This caused the vehicle to brake unexpectedly while driving through a construction zone on highway 45. Fortunately, we were very close to the Acura dealership where the vehicle was purchased and managed to drive the vehicle to the service department. The Parking brake alarm continued to display on dashboard even after turning off the vehicle and starting it again. The emissions alarm also flashed intermittently on the dashboard. After researching on several TLX Forums, we found similar incidents dating back to 2015 TLX vehicles. There is also an issue when trying to start the vehicle. Sometimes the engine does not turn over and the dashboard displays error messages or goes completely black. Dealer is unable to fix this issue. Vehicle has been in for repairs a number of times with no resolution. We are not sure if the starting issue is related to the parking brake issue. There seems to be major issues with the electrical/software/firmware.
