Re: 2014 Fiat 500 1.2 acceleration issues

What I'm now finding odd is that the '63 plate and earlier responders are equally tied between experiencing the problem and not. If that is the case, why haven't we heard of this before?

Sorted that for you . I think those statistics are potentially skewed by the "earlier" 500's mainly appearing to be 2013 models, presumed on a 63 plate and very few of the 2007-2013 owners actually having responded, including the OP.

I gave the pre 2014 option so that people wouldn't skew the 2014 statistics, it's kind of a nothing vote for pre 2014 people

Re: 2014 Fiat 500 1.2 acceleration issues

Ah screw it. Today I drove a 14 plate 1.2 pop with 80 miles on the clock which someone at work has as a courtesy car as his recently purchased Grand Picasso has brake issues. It was absolutely fine, I tried driving it gently, not gently and with various different levels of throttle opening and it was fine. It was a exactly as I'd expect in in terms of power with it being so new. So the issue is not a 100% issue as has been suggested. For the record the guy didn't have any issues either
Thanks Oga, jrkitching thanked for this post

Certainly looks that way. It also looks like it's not a 0% issue, either.

This could be going the same way as the S/S thread.

In the case of S/S, some cars are fine straight out of the box, some need physical work (part replacement/sensor adjustment), and some are down to user misunderstanding about how to operate the car. Dealers often place all cars with issues into the last category, instead of getting their hands dirty, finding out what's wrong, and fixing it.

I can only imagine how frustrating it must be for those who have a genuine problem with their newly purchased car.

I would still like to know more about the rumoured two stage clutch position sensor.

Re: 2014 Fiat 500 1.2 acceleration issues

My opinion.... And I must stress this is just an opinion.... The clutch switch is a made up thing. Why would there be a dual stage switch? The clutch really has two positions where you'd want it to be, either in or out. Obviously there is clutch slip and this depends whether you're doing a hillstart on the Hardknott pass or trying to get out of a Tesco car park that has a slight gradient to assist with drainage.

Maybe I'm wrong, but I don't see the point of this supposed dual stage switch therefore I strongly suspect that it's a myth perpetuated by well meaning service people.

I certainly agree with your statements about an acceptance drive, but I wouldn't advise anyone not to order a 1.2 as long as the dealership allows this acceptance drive.

I'm keeping an open mind. But if it does turn out to be a myth, those well meaning service people should be strung up - that kind of misinformation helps no one.

That's exactly where I am on this one right now. The 1.2 is a great engine choice for the 500 and I'd not want to see anyone put off ordering one unnecessarily.

I also wouldn't want someone to take a new car home with issues that, at the present time, the dealerships seem unable to sort out.

An acceptance drive before handover is the sensible compromise.

Re: 2014 Fiat 500 1.2 acceleration issues

2010 1.2 500 POP 42k on clock.

I do mostly motorway driving with very few starts, I have being feeling that my POP has been bogging down a bit as I try to pull away from stationary lately.

Have spent most of my time driving gently, max 3000 rpm. Now I'm driving with a bit more enthusiasm just figured car was not used to it & was bogging down but would go away as I continue to drive more enthusiastically.

I might try an Italian tune up or two.

On the other hand, after nearly 4 years, just looking at my 500 still makes me smile.

I appreciate the need to remove noise from survey results.

However, the poor throttle response was first reported on the forum in late 2013. The stats for 2007-2013 contain these cases which skew the results in a way that suggests that the problem has been around for much longer than it actually has. This was my explanation for the anomaly that Cei pointed out, ie "why haven't we heard of this before?"

Re: 2014 Fiat 500 1.2 acceleration issues

I picked up a new 2014 Panda Easy 1.2 this morning, I've only done a handful of miles, but no issue with acceleration.

Given it isn't every euro6 car affected, perhaps hope exists for a fix for those affected.

It feels different, and driving style will need to change slightly, but prefer this in every aspect so far to my 2010 1.1 Active Eco.

So much for David Bliss' supposition that all Euro 6 cars were affected, but you won't apologise I'm sure

Slow down, Tiger - we still don't know for sure what's behind all the issues that folks have been having.

But I'd agree the leaky manifold theory fits the facts as they've been reported thus far.

Good news if true, as it should be a simple fix for those experiencing this problem.

Photos of any problem cars with missing bolts would be helpful.

Re: 2014 Fiat 500 1.2 acceleration issues

A simple bolt missing fix would be such a easy fix for those if this is the root cause ,let`s hope so for those affected ,so they don`t have to go months ,experimenting waiting and hoping for our beloved Fiat company to catch up

Tbh when I drove a 14 plate car that was fine I was happy to put my t-shirt over my head and run around shouting gooooooooooooooaaaaaaaaaaaaaalll


The signs never pointed towards this being a problem with every new 1.2 8v engines 500/Panda
