Q: 2005 Mazda3 Sport computer not working

asked by on

My car's computer is not working.

There is no information on a computer failing on these vehicles. The computers in these cars are very dependable. I would need more information to help with your diagnostics. A mechanic could check the system to see if a computer was hit by lightning or some other act of nature. I recommend you have a mechanic, like ones from YourMechanic, come by and inspect your car’s electrical or computer issue.
