I've had the dash lighting issue as well, the gear changes and a bunch of other stuff. The dash lighting has a habit of switching to dark mode in tunnels etc and then not switching back to day mode afterwards...and those early gear changes can feel horrible when it jerks.Mine went back today for a range of issues, worst Mazda I've ever had for that! Suspension we all know about. Mi drive dropping out at dangerous moments and the car not accelerating. Limiter randomly kicking in, also dangerous. Radio not working sometimes, Dash illumination staying dark when it should be light and vice versa. Constant "12 volt battery low" warnings. Strange two stroke bike type noise. And very rough gear changes.
Last car I had with that many faults was an Austin Montego in the 80's
The MPG is also ridiculous and nowhere near what it is stated as being. Its currently costing me about the same as my old 400bhp Subaru Impreza WRX STI Type R that guzzled unleaded like a Stella drinker at a football match, and thats without the battery being empty. God knows what it will cost when that does happen on a long trip and what it will then cost mile per mile.
The battery recharge from engine button is Esso's dream button - you can literally watch the fuel gauge going down after you press that.
My first Mazda, and slowly becoming a regretful purchase and the realisation that it will probably have to go and Im going to lose a big chunk of change.
