mazda 3 1.6 Diesel 59 plate stalls and judders

TomBrooks95

So, I bought this Mazda 3 1.6 Diesel (62k miles) on Monday from a dealership who claimed to have done servicing, MOT, etc to it.

However, it is a right pain to drive.

The first problem that occurred was that the engine just decided to cut out on me all of a sudden as I was going onto the motorway. I was doing roughly 60 mph and 3,000 rpm. When I went to apply my foot to the gas nothing would happen. I drifted by to the hard shoulder and had a little look at the dashboard there. The only two lights that were on were the oil and battery lights which show that the engine stalled apparently.

I started the engine up fine again and off I went.

The exact same thing happened again the next day, except I was going up a hill doing about 35 mph at around 2,500 rpm. So I pulled over again and turned the car off and on and all was good.

However, since then I've noticed that the car begins to judder along when I apply my foot quite hard to the gas.

Another thing is that the engine temp light comes on whenever I go to drive it again after a prolonged period of time, so I try to drive it as economically as possible until that light goes off. The light takes a good 6/7 minutes of driving to go off and if I even think about going over 2,000 rpm the car will begin to judder and I get scared that the car will stall itself or cut out again.

Does anyone have any advice on what my problem is here?

I've taken it back to the garage today for them to fix as it's under warranty, but they've told me it doesn't sound like there's a problem.

Cheers!

Take it back. There is a problem, it shouldn't do that. Without being able to do any diagnostics its hard to say for definite over the internet but it could be a fuel pressure issue so could be a blocked fuel filter or a failing fuel pump. It could equally be a faulty camshaft position sensor which itself could be caused by swarf from a failing dual mass flywheel, unfortunately there's quite a few things that can cause that to happen.

You've just recently bought it so you have the right to reject the car within 30 days of purchase and now you've taken the car back for that fault that clock has frozen.

Thanks for the advice. So even if they tell me that the car is fixed, do you recommend to me that I return it?

reject the car, this will end in tears. Hand the car back, with a letter. How did you pay for it? How did you pay for the deposit?

TomBrooks95

So I've paid an 800 deposit via my debit card and then I've got the rest on finance, but I was told that I had two weeks from when I got the car to back out of the finance agreement. I presume I'd get my deposit back if there is a fault with the car, right?

Finance are jointly liable, they own the car. Best get onto them and tell them you are rejecting it. Give them a buzz now and report back, they should have a process to follow. Otherwise, they might tell you to put it in writing.

Will do. I appreciate the help, thanks so much!

Woman at my old office had one of the Mazda 3 of that era and had the same problem, probably why the newer model has the new SkyActiv engine

It’s the Peugeot/Ford engine

No, it has the new SkyActiv engine to meet Euro 6 emissions.

So nothing at all to do with a known fault in the old engine which caused it to cut out, an engine that would have passed Euro 5
