Mazda BT-50 Problems

It’s possibly a faulty sensor sending the wrong signal to the ECM. Have it checked by your dealer or mechanic.

The Ranger, and its cousin from Mazda, is a tough, durable and reliable truck. Neither have any major problems that should concern you. Buy on condition, look for one that has been used privately rather than for work, and make sure it’s been well serviced.

I’d guess there’s some serious internal trouble and that you should take it to a transmission specialist to have it assessed.

I agree that it is not an acceptable situation, and believe she has good ground on which to claim a full refund. The car as delivered was clearly not fit for purpose, which is proven by the extended time that Mazda has taken in so unsuccessfully attempting to fix it. I would call in the ACCC.

No. That’s an odd one and needs investigation to determine what’s gone wrong. I’d suggest consulting a diesel engine specialist.

The main pack has three leaves.

 There have been other reports of BT-50s and Rangers shutting down, but they can usually be restarted. The problem with that is that the problem doesn't exist when the car is taken to a mechanic to find the cause, but because yours wouldn't restart the mechanic might be able to identify the cause.
