Each component in detail
What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
Vehicle was exhibiting erratic indications in all safety systems. Was checked out by dealer told all was OK. Two weeks later vehicle indicated warnings in various safety system, instrument cluster went dark, speedometer and tach were inop, blinkers did not work. Car taken to dealer again where it was determined that water incursion into passenger side foot well as the result of clogged sunroof drains had resulted in water damage to the signal acquisition module and other modules regulating the CAN Bus which were mounted in a location susceptible to water incursion and damage. Routine service does not include assuring that sunroof drains are open. Given the nature of computer systems in this vehicle such water damage has the potential of serious safety issues. These modules must be relocated to an area not prone to flooding. MBNA was contacted and provided no customer support whatsoever. The repair was almost $2500.
