Mazda BT-50 Problems

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

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.

 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.

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

The main pack has three leaves.

The official fuel consumption (average) is 10L/100km, which is a guide to what you should get, but it will vary depending on the driving conditions, load carried etc. Yours isn't wildly out, and given that it's new and running in you could expect it to improve as it does more kilometres. I would suggest you report your concerns to the dealer and maintain a log on the consumption you get with the view of presenting it to them at the next service. If it hasn't improved by then you should have plenty of evidence to justify your claim that something is not right.

The range of values for your vehicle is $29,000 to $32,000 as a private sale. As a trade-in it’s worth $24,000 to $28,000. With its low kays, plus the towbar and bullbar yours is probably at the top end of that range. You don’t tell us anything about your needs and wants for the car you are looking to buy, but the Kia Sportage is a good car and worth you looking at it.

It's most likely an intermittent fault with a sensor. By restarting the engine you are rebooting the computer, which is a sign of a fault in the engine management system.
