Hi all,
As my 5 month-old Jazz HX has "run in" I've noticed some odd, in some cases, concerning behaviours with the car and I'm wondering if anyone else has experienced similar.
On a couple of recent occasions, in cold or damp conditions, within a few hundred metres of starting off, the engine and transmission system seem to get stuck in a state where the rev counter sticks at about 2,200rpm (even when the car is coasting). If the MFD is to be believed, the regenerative braking is still working on the downhill and the IMA is cutting in under load but the revs sound abnormally high and constant in pitch and, although the car still seems to manage to respond when the accelerator pedal is pressed, there's very little power available. The second occurrence was this morning and the only way I could clear the problem was to pull over, switch the ignition off, then restart it. I'm thinking of taking it into the garage to get this looked at, but since it happens intermittently, it is going to be hard to reproduce so I wondered if it is a problem that anyone else has encountered and might know more about?
Over the last two or three months, it seems to have got more hit-and-miss as to whether the auto-stop activates or not when the car comes to a halt. I know it doesn't trigger when the engine is cold but I've noticed that, even when warm, sometimes the auto-stop triggers and sometimes not, and it doesn't seem to correlate to ambient temperature, rate of deceleration or load due to ancillary systems such as lights and heater.
Every time I get the car out of the garage, there are a few drops of water on the garage floor, roughly corresponding to where the back of the engine compartment has been. I get the impression they are only produced at the time when the car is started up because there is not enough water present for it to have been dripping for a prolonged period. I wondered if there was a drain point in the exhaust system which might be the cause of this?
The fuel economy seems to have dropped from more than 61mpg (reported by the MFD display in the car) back in September to about 55mpg on the same route recently. I guess this is partly due to increased usage of lights and heater, and probably the cooler temperatures affecting the battery performance, but it still seems quite a substantial reduction. Any comments?
All advice and experience gratefully received.
Cheers,
Mister P
