My uncle bought a new Dzire just 2 months ago and we have been experiencing a problem number of times and even m.s.s engineers can't figure how to fix it.
While driving the car at around 80kmph on 4th gear, the rpm is aroud 2100-2200 and the car is in turbo range at that speed as turbo kicks in at 2000rpm.
When at that speed and rpm, gear is changed to 5th, and after changing the gear when the clutch is left, engine starts shaking and rpm drops drastically and reaches below 1000 mark and ultimately, while car is running at 80kmph speed, ENGINE DIES!! Power steering stops working and all the normal signs before starting the car lights up. (AC was working everytime when this happened).
And when the car starts shaking and the rpm is dropping, when I keep pressing the clutch for a time, car stops shaking and the rpm also stabilises.
This might be very serious problem when driving on Highways.
And when I start the car after stopping the car, White smoke from exhaust starts coming ( smoke came out, like in 7 out of 10 times when this happened) and I have to restart the car after waiting for a while, and then it starts normally.
I went to M.serv. station, they drove and tested the car, but unfortunately nothing happened at that time and they said that they have no idea about this problem and they could only solve this if it happened in front of them. On my request, they agreed to check the car, they checked the fuel pump, diesel samples and some more things, and they came up with the result that the diesel in your car is not upto the mark, so please change the Filling station (although the f.station I go is one of the best in the city), although I changed the station, But this problem is still there!
Can anyone please help me?
I would like to add, that car is pulling and performing perfectly at low speeds.
