New to the forum but have been doing some digging and can't see anyone else with the 'problem' or perhaps 'feature' that I'm seeing with our late 2013 CX5 Sport Nav 4WD Auto 175bhp diesel.....
After the first start of the day it does the normal 1500 rpm initially - no sweat. Put it in 'D' and drive off, but for the first 2-3 miles the engine revs at an almost constant 3000 rpm irrespective of road speed i.e. you hit the accelerator, the engine runs up to 3000 rpm and it pulls away with almost imperceptible changes. However whether you're at 30mph or 70mph the engine is doing 3000 rpm.
Sometime well after the blue 'cold' light goes out, the engine revs eventually drop to normal and gear changes sound normal. It feels as if the gearbox is slipping for the first few miles or so until things warm up.
Not sure how this 'box works - guessing there's a fluid torque converter and either wet or dry clutches to 'lock up' the transmission for efficient and again it feels like only the torque converter is transmitting any power initially.
It has been back to the dealer (less than 7000 miles on it) and they say "there's no fault codes, it's normal" but it doesn't seem normal to me and I don't recall it doing this when we first got it.
Unlike the well-known 1500 rpm 'warm up' in neutral immediately after a start, there's nothing in the manual to say this behaviour is by design e.g. to assist quick warm up.
In fact I'm not particularly happy as there's no way to get it to do over 20mph for the first 3 miles without revving the engine to 3000 which for a stone cold diesel is not what I would choose to do.
Anyone else seen this behaviour? Or more importantly, for those with the 175bhp auto diesel does your gearbox change normally from a cold start or does it act like mine? Want to understand that please before I call Mazda / go make a fuss at the dealer.
Thanks...../.
