Re: Verna : Car jerks when accelerator/throttle is released
Hi friends , i have a Fluidic Verna Crdi purchased in february 2012 . Few days back i completed my 20k kms and had my third free servicing done . I am facing a strange issue now . When i let go the throttle/accelerator my car jerks a bit to a level where its uncomfortable . Can feel the jerks in all shifts but are more evident in the first and second gear . I dont feel the jerks if the accelerator is released when clutch is applied . Did anyone of you have faced a similar issue .
Also my car comes with extended warranty , is it provided by hyundai or the showroom where i purchased it ? Can anyone clarify .
Hi Rohan - I have this issue in my car (Figo D) from day one. Every time I approached the service center for this issue, they would adjust the clutch beading or something and do a mass lubrication which will work for few KMs and it will reappear. No permanent solution done yet and I am not sure whether they can find one. Even now, I have raised it with Ford again as I was suspecting it for the Low FE concern.
Have you taken the car to the Hyundai Service Station and pointed out the issue to them?
What was done at the 3rd free service?
It could be a fuel pump issue.You should take the car to the service station and get the problem diagnosed.A common problem with a lot of Verna's is the clutch slave cylinder.Get the clutch cover,clutch plate, bearing, master cylinder, slave cylinder checked if the issue is not related to the fuel pump.
If your car is equipped with a tachometer, you can check if its a clutch issue.A worn out clutch will slip and to reach a certain speed,the engine will have to revved higher than usual.
Most service stations will hook up an ECU reader and check for faults.Ask them to check all electrical connections.Sometimes faulty electrical connections can cause issues with the fuel pump.Like the coupler that connects the ignition to the fuel pump.One of our members here faced a similar issue.
Hi Jarpickle - Seriously man, you have a lot of points for every issue. Appreciate it.
Here is my understanding in this issue. This could be basically due to the mismatch or desynchronization with the Engine RPM & Speed. Say if the RPM in tacho is 2000 in 2nd gear and when the clutch is engaged, it would go down to the idle range say 850 and once the gear is shifted and clutch disengaged, it will go to 1500 or so. I believe, this is normal as the RPM for 2nd & 3rd gears would vary. However, the speed of the vehicle (Wheels) would remain the same or may not drop as much as the engine speed did. So the Engine RPM after the shift isn't matching or lesser than the Speed or Wheel RPM which is causing this Jerk. Similarly, a forward jerk can be felt if the Engine RPM is more than of the wheels.
I tried to match it with little extra throttle, which may burn more fuel and at times gives a forward jerk, but isn't smooth or better matched. I suspected my driving style and tried in other cars, they were perfect!
