I would like to inform you that in June 2000 I bought a brand new XXXXXXXX motorcar bearing Chassis number XXXXXXXXX. A few months later I found a fault related to the electrical system. Firstly, it was an airbag problem. The warning light of the airbag was continuously turned on. Later, there was a serious problem with the electrical system due to which my car was immobilized in a near town. Afterwards, it was another problem with the thermostat of the radiator and my car steamed and finally immobilized in the motorway. And then, once again, the temperature gauge caused several problems by being out of order. Now, the starting system is out of order again, that is: every time, on starting the engine, the system goes out of order, the switch seems to be dead and all the lights (warning etc.) turn off including the clock, which restarts from “1:00”.
This unacceptable situation takes up time from me (now, my car is still in the garage for the second day). But the most important is that I'm in a quandary about what to do with my car. Do the problems concern manufacture problems?
I will be grateful if you help me find a solution on the above. Neither being separated from my car nor changing my mind about xxxxxxx’s efficiency would be likeable because my car is useful and very suitable for my wife.
Thank you in advance.
