Brand new 2020 Abarth 595 hard to start and missfire
« on: December 22, 2020, 02:15:59 am »
I just bought the brand new MY20 Abarth 595 auto from Brisbane in Nov 20. The car now has 1200kms on the clock. I have noticed heavy vibaration when stopped at the lights and cruising around 10km/hr on the first day with/without AC on. 600kms later, the car struggles to turn on in the morning at first go. 2 or 3 times later it fires up with poor engine idle vibaration and check engine light flashing for few seconds. I have tried different 95 fuels after reading from this place and has not fixed it.
At 1100kms, I took the car back to the dealer for initial service and told them the issues. The dealer came back with all cylinder missfire code stored and suggest me change to 98 which I did after the service. With the new 98 half way gone, the issue has not gone away, so I tried to disconnect the battery to reset ECU and still no luck so far. Have any way expirenced this issue? :'(

    It should run on 95 octane fuel, they're fobbing you off.

    I think its coil pack and or spark plug related

    Yes I have heard alot talks about coils and spark plugs, occasionally fuel pump replacement. I just want to see if anyone else had same issue and outcome of this matter.

    It's a brand new car and got a three-year warranty.
    Get the dealer to FIX IT>
    If not get on to FCA and get them to fix it.
    While it's under warranty the dealer will fob you off if you start playing around with ECU etc...

    I will keep taking the thing back to the dealer until fixed, however the dealer does not have a clue what is wrong with it. I was hoping someone here might had the same issue so I can get it fixed sooner.

    After few hours of study on the 1.4T engine design, I am pretty sure the starting issue is not fuel/fuel pump or spark related. The issue maybe caused by intake valve not opening due to low oil pressure in Variable valve actuation assembly that uses pressurized engine oil to open the intake valves. It is very common when vehicle is stored for long period of time without starting. However, loosing top oil pressure overnight maybe caused by faulty pressure sensor or pressure relieve valve in oil pump. I will take the vehicle back to the dealer and show them the new finding. I will also attach links with more info for everyone here with same problem.

    Just to be sure, is your engine a 'Multiair' or 'Tjet' design?

    I, perhaps wrongly, assumed the Australian A500 was the 'Tjet'.

    Your prognosis would only refer to the 'Multair'.

    if you get no love from the dealership, give either Vince from ARI (Sydney) or Antonio from Antonios service (Melb); both great guys, both know there Abarths and will put you in the right direction.

    Otherwise, trip down to Coomera and see Aaron and the boys at ASG motorsport. They're very familiar with the ins and outs of abarths on the goldy!

    Hi.

    I mean no disrespect at all here, but, you shoulden't be doing any of what you are suggesting.

    If this indeed a brand new car and it is not working properly then it is not fit for purpose. If the dealership has no idea what is wrong then it is up to Them to contact FIAT for advice as to what to do.

    If you persist in your actions it will be seen as "Customer is not that bothered" and as others have suggested you will be fobbed off.

    You paid for a brand new car that is fit for purpose and functioning correctly, which it seems it is not. So take it back, insist they refer the issue to FIAT or something but put the onus back on them, they are the ones you have the contract with.

    If you start messing with things or driving to other places and let them do things then your original dealership may throw this in your face and maybe even void any warrenty.

    Maybe you should talk to a solicitor and see where you stand from the law point of view?
    The beatings will continue until morale improves.

    Thanks for the advise.
    Agree that it should be taken care off under warranty; unfortunately with dealerships in Australia (especially in qld) mechanics and service departments are not all that familiar with abarths! (let alone Fiats). They will more than often play the "plausible deniability" card and won't really delve too much in resolving the cars issues.
    Going to, or contacting passionate/specialists for a bit of advice, to then take back to the dealership usually ends with a quicker and positive result.
    Just saves a lot of grief and time!! Also helps with connecting with the Aussie Abarth community and getting the After market Mod bug itched................ ;D
    Stay Safe

    Totally let Fiat fix it. Or at least try to! I would only go independant if all official efforts failed.

    I am just intrested in the fault as I am a mechanic myself, I also went into more info about the EVAP system on all new vehicles. If the EVAP purge valve stay open or the hose between the valve and manifold leaks, your engine will suffer cold start issue, poor idle and poor fuel efficiency as the engine receving more air as measured from MAP sensor. However with faulty valve unit which controled by the ECU will not detect the fault all the time and cracked hose will not thraw any code beside missfiring, it is pretty hard to detect the actual problem. Maybe this will help.
