Mazda BT-50 Problems

You need to take it to a mechanic for a diagnostic check to find the cause of the problem. It sounds like it could be in the transmission; perhaps the powertrain module could be at fault.

Without being able to view it and hear it firsthand it's hard to suggest what might be wrong. It could be a bearing in the turbo, but that's only an educated guess. I would have a mechanic check it.

You can buy a steel tray for it, but that alone is unlikely to stop the back end from stepping out in slippery conditions. The old way of stopping this sort of thing happening was to put some load in the tray, some bags of concrete or sand will help, but you also have to drive it to the conditions.

Is it something new, or has it always been this way? I’m wondering if you’re just feeling the diesel engine, which works best at lower engine speeds. Rev it too high and you’ll lose the effect of the diesel torque. It could simply be that, or it could be an electronic problem. Have a mechanic run a diagnostic check on it to see if there is a problem.

There is a current recall affecting 30,505 MY 2016-2018 BT-50s. It relates to two front brake issues, one for a potential front brake hose failure, the other for possible front brake calliper cracking. Both could affect the car’s braking. To see if your BT-50 is one of those affected phone Mazda Customer Support (1800 034 411).

It is a relatively common problem, and it’s made worse by towing in 5th gear.

On average a 2010 model should have done 200-250,000 km, so you are correct in thinking it is high. The BT-50 is generally reliable, but having done almost 400,000 km you have to hope for the best and be prepared for the worst. Having a good service record is a bonus.

As there are no warning lights, and it recovers if left, it doesn’t seem likely that it’s an electronic issue, rather a mechanical one. It would worth checking the turbocharger.

I’d be checking the clutch to see if it could be worn out or close to.
