2004 Mazda RX8- numerous dash lights appear constantly. Could this be electrical or a ground problem??


Asked by Oct 04, 2013 at 02:31 PM about the 2004 Mazda RX-8 6-speed

Question type: Maintenance & Repair

The check engine, traction control, coolant and AT  dash lights appear on a regular basis. Only when the AT light appears does the car have performance issues. The only light that stays on regularly is the check engine. General mechanic thinks an electrical or ground issue. Please advise

The Mazda Rotary is in a class all by itself, they have all kinds of check relays so everything has to be up to specs for them to work properly, so you need someone that knows the RX 8 before you let them work on it. Electrical grounds could be the problem, but you really need to get the hard fault cured and then go on from there.

I would check the battery and alternator to make sure they're working properly. Not enough battery voltage can cause all types of issues.


How many miles are on the engine? I was having the same problems and then started losing power.. now I am told that that I need a new engine! Mine has almost 100,000
