Hi All, new to the forum.
I got my GT Diesel back in late March, first one off the boat in Melbourne I'm told. Very happy with it, already chugged up 11,000km in that time.
Have had a gripe since new that Mazda think doesn't exist - after cruising on the freeway for anything more than around 15 minutes at 100km/h (~60mph), the i-stop light goes out, fuel consumption goes up by around 20-25% on flat roads, and if I come to a stop in traffic (as is often the case in Melbourne's peak hour), the engine revs at around 800rpm as opposed to the normal 650-700.
I often find it 'comes good' again after 10-15 minutes of urban driving, and the i-stop comes back on again. This is repeatable - can go back on the freeway and the whole thing repeats after 15km or so.
Have asked local dealer to check this twice, each time saying they couldn't find any problem.
Anyhow, most of my travel is stop/start in metropolitan traffic, so no big deal normally.
Well, today, my wife took a drive of about 25km to a friends new home for a housewarming, and calls me up when she arrives. "The car is all juddery and there are warning lights on.
I just so happen to have the CX-5 manual at home, so I check what they mean.
1) Engine symbol
2) Traction Control symbol
3) Tyre Pressure warning symbol.
jumped in her car to check it out. Tyres normal. Drove down the road and notice the gearbox is not changing gears correctly. Seems to rev very high when accelerating and changes gear very late, even under very gentle acceleration; and feels like its going to stall when braking, to the point that when it does change down, the car lurches forward - hence the juddery behavior reported by the wife.
So I leave her Mazda-2 with her and take my sick puppy the 25km home for some TLC.
I noted that when switching from AT to MT, the display (that normally shows an 'M' plus the current gear) was showing just an 'M', and cannot manually change gear any more.
My feeling is the ECU is screwed up - the fact it's showing a traction control warning light, engine warning light and tyre pressure warning is bizarre.
Has anyone heard or seen anything like this? I saw a video on youtube on a Mazda-3 that looks just like this.
Not sure if the two issues are linked, but my gut tells me they are.
Thanks!
Chris
