Hi all,

Had the BT50 for just on a month now. Great tow vehicle for the three horse float, and pretty economical too.

All's good, except for;
- speedo is close to 10% out, and
- there's a vibration when accelerating in first at around 15-20 kph. Feels like drive train shudder, and can be felt through the drivers seat and the steering wheel.

Took it back to the dealer and was told 'all the ones on the lot do it, it's normal'. I'm going in to test drive some of the others in the next day or two.

Have any other BT50 owner experienced a similar vibration?

Sure did Dave, was on the auto's. Main problem was the centre tail shaft rubber, well thats what they put it down to, but funny they did it from day one. My VL commodore was also bad for it, come to think of it so was my VP, VX had it in reverse when reversing up some thing steep (my driveway) big time with the ski boat on the back. mmmm must have been a standard thing issued from Holden free of charge LOL.

Yeah, my VS Statesman does the same thing. It's the tail shaft, an added feature you get with the car.....

Mazda reckon that they checked the tail shaft and that it's ok....

Is it a new vehicle..? If so I wouldn't be happy if it's a vibration as you call it. Driving some other ones would be a good idea. You say the speedo is out by 10%, have to changed the wheels..? Both of these issues are not acceptable in a new vehicle, afterall it isn't a Statesman or a Commodore, it's a Japanese vehicle. LOL

Seems to be a common thing with speedo's these days to be out. Wifes Toyota (06 model) is out by 7klm's but at least the right way meaning if the speedo says she's doing 60 she is actually doing 53. I have checked it with two GPS systems which are supposidly 100% accurate. It is out by 7k at all speeds 60k /110k. Must say we had a 97 V8 5L VS statesman and didnt have the vibration must have been a friday car and left the added vibrating bit out LOL. Regards Steve M

Vehicle is bog stock standard. All options are factory fitted (or dealer fitted).

Spoke to the dealer in great detail today.

The Australian ADR's state that car manufactures can only make their speedos accurate to -10%, ie read fast. There is no allowance for them to read slow. Apparently Mazda have decided to go more towards the 10% end....

As for the vibration, the dealer is actively chasing up the issue with the local traveling tech. It looks like a drive train issue.

So far the local dealer has bent over backwards to help. A lot more forthcoming than Mazda head office.

cheers

At least they are trying to help you which eases the frustration a bit at least. Hope they resolve it for you. Nothing worse with a brand new car. Keep us informed as to what it was when you get it fixed. Regards Steve M

Hi Barry, If you have a GPS navigator its speed is pretty correct.

One of our Isuzus reads 6 kph slow good when doing my fuel consumption, instead of 9.4kpl its 10kpl I like that hahaha

Cheers Bruce

PS what is your fuel consumption towing your van please?
When we upgrade our vehicle we are pretty keen on the BT 50

Does that mean that your warranty runs out 6K early?.... 94K instead of 100K...

I'm getting aroung 15lt/100 towing a three horse float, approx 2t. Given that they're like towing an air dam, I think it's pretty good. Also, motor has only done 3000 klms. Should get better as it frees up.

Cheers Russell

Thanks for that info Russell, did not think about the warranty thing, they get you every where don't they. R well not really a problem for me as I have not brought new for many years, I like to have them sorted before I buy, actually can not afford to buy new.hahahaha.

Cheers Bruce
