Bought brand-new in 2005. Had multiple, recurring problems with the computer/electronic systems. The symptoms usually start with the “T/C” warning light, and can end up with a entire load of symptoms: All the lights on dashboard that are flashing, all the warning symbols are displayed on the info-screen, bells dinging for power steering, gauges fluctuating [i.e. speedometer oscillating between 10-100mph, same with rpm meter], ticking/clicking noises coming from gear-shifter area, door locks going up-and-down, car jumping as if the transmission is slipping (as if you would accidentally change gears with a manual shift from 2nd to 4th, or something like that), sometimes the steering wheel gets blocked, sometimes the engine shuts down [especially if slowing down for a stop sign or traffic light].
