So I've had my 2011 Fiesta Sedan (SEL) for one week now. I've put about 150 miles on the car and have noticed some strange behavior from the 6-speed automatic transmission.

I bought this car for the high MPG. As such, I drive with a very light foot on the accelerator.

What I've noticed is that between gears 3 and 4, the engine seems to surge/pulsate a bit. I'm hoping that all the electronic controls are adapting to my driving technique, but it concerns me the the car seems to lose acceleration at this point and bog down. I've got people riding my bumper because of the slow acceleration as it is, but when the shift between 3rd and 4th takes place, I've got people rapidly bailing from behind me and zooming past. There's definitely a pulsation in the acceleration at this point.

Hoping it's the transmission in learn mode, but wondering if anyone else has experienced this.

Same here.... have you called the dealership to see if this is normal? I'm gonna call to see what's the dealio cause supposedly it should be smooth shifting between gears with the new type of tranny. Let me know what news you get.

Yes, please post anything you find out. I'm considering buying a new Fiesta and I'm trying to decide between the automatic (supposedly sluggish when down shifting) or the manual (would be my first manual car).

Thanks!

Well Clark, as I have only test drove a manual myself, and being both a stick shifter driver my whole life and ride a motorcycle. I can tell you the fiesta would be a perfect car for a beginer. The clutch pedal has minamal push effort and the long gear shifter makes it easy to tell which gear you are in.

I have noticed the same staggering or blubbering phenomena on a few occasions, most notably when accelerating slowly. I have notified my local dealership and plan to have my vehicle inspected within a week's time. I'll report back with any findings. Meanwhile, have other members heard back from a service specialist yet?

Yeah, I've had mine for about a month and put about 3,000 miles on it and not only did I notice the pulsating between 3rd and 4th but I also had issues with geers 1 and 2 bucking and slipping some. I took mine into the dealer about a week ago and they first said that there was a software update that needed to be applied for the transmission to "learn" how to shift but that my car would not accept the update. They put a call into Ford and they said replace the transmission. My transmission is on order but I have no date as to when it will get to the dealer. I love the car, but it's been a week and this kind of problem doesn't inspire a whole lot of confidence. This is my first Ford and I was excited to buy it, but now I'm thinking the Fit might have been a better buy. I guess I'll just have to be patient and see how it drives with the new transmission.

Sorry for the late reply. I haven't contacted the dealer yet, but will try to do so in the next week or so to see what they say (too much other stuff going on). I figured the shift points were selected for the fuel economy and that if they changed them, that advantage would go away, but seeing the forum member below who is getting the transmission replaced, I'm more motivated to do it now.

In the meantime, I've adjusted my driving style a bit and it has helped. Basically I'm accelerating a bit more aggressively, which helps get the cars behind me off my bumper but doesn't, according to the MPG indicator, negatively impact my fuel economy (too much).

It turns out, as Gnuwave suggests, that the Fiesta's transmission is unique in its design, which results in high revs and quick gear changes for better fuel economy. As my service manager pointed out (which he heard from Ford engineers), the automated manual transmission on the Fiesta creates a very different driving experience than one might be accustomed to with an traditional automatic transmission. The most notable changes appear to be the slight clutch noise near walls and at low speeds as well as the longer shifting points (and, hence, high revs) for lower gears. However, I don't know about the clunky shifting that sometimes occurs during traffic when I need to accelerate quickly.

All of this makes me wonder whether I should have waited for a later model with the EcoBoost engine, but perhaps it would have the same transmission too!

(Please disregard the duplicate post below)

How did you know whether you were in gear 3 or 4? Does the car have a gear indicator on the dash? The Lexus IS has that feature which shows which gear the car is in. I'm not sure about that on the Fiesta. Still waiting for my order to come in.

I had my initial service last week (4.5k miles) and reported that the transmission at low speed & with a hill/stress it usually doesn't know what gear to choose &/or the engine is slow to provide "go". When "it" (transmission/engine) finally makes up its mind, the car surges ahead. I knew of this issue prior to buying the car in July as the four reviews that I had read all commented about this issue. I thought that , as the car was still new and it was a software issue, Ford would be working on solutions.
As I expected, the service tech didn't find a fault nor couldn't replicate (no hill/stress) my complaint. The service tech contacted Ford & said the response was "no known issue/problem". Either Ford was lying or they have their collective heads in the sand. January's Consumer Reports (which I received a couple of days after I had the car serviced) stated under Ride, handling, and drivetrain "The six-speed, automated manual transmission shifts responsively, but power delivery isn't smooth at low speeds." I told the service manager that this wasn't a "deal breaker" as, overall, I really like the car, but the condition is disappointing given the overall exceptional engineering.

I found a bit of a learning curve in driving with the automatic transmission. Especially, when you first start out cold in the morning the transmission does seem to run the engine rpm's up a lot. Like a lot of things, with a little practice it all becomes second nature. It all seems to smooth out when things are well warmed up. I do notice some uneven acceloration when the car is cold, feels to me like the engine may be running a bit too lean, or the valve train is adjusting itself, I don't think it is a problem with the transmission.

Whatever, the gas mileage of this vehicle really impresses me, it is at least equal to or better than my hybrid Camry. I often get over 40 mpg (in this rural area) and with gas locally coming up to $3,00 a gallon, I will opt for mileage.

Hate to tell you this - but I have just been through the identical situation: 2011 Fiesta SES w/6 speed auto transmission. Owned it for 10 days of short distance driving. Took it back to the dealer who said they would have to change out the complete transmission assembly on order from Ford. Big problem is they had no spares anywhere in the US of A! Swear to God - that's what Ford told me! So the car has been at the dealers for over two weeks because they said the problem was too serious to continue driving the car. And I wait. And I wait. PS: Notice my log-in..that was because this is the first American car I've ever owned. Clearly a big mistake!!

If anyone else has had a problem with a 2011 Fiesta with the six speed auto - take it right to your dealer and demand they replace it. It has something to do with the dual clutches and it is becoming evident that this box has some problems. If you don't take it back for replacement, it will only get worse and could cause other problems (That is a quote from my Ford dealer). Of course - the best part about this story is that Ford doesn't seem to have any spares anywhere in the USA, so like me, you can probably expect to wait weeks before they can ship one out to your dealer. So Much For The World Car!!

HI,

I have bought the fiesta car with automatic transmission a week ago. The first 2 days I hear some strange noise when I accelerate the car passing from the low gears to the high ones.

I suppose there´s is a problem of the transmission at the moment of the shifting between gears.

Guys, has somebody have this problem ? Could be solved applying the TSB 10-19-6 ?

After changing my muffler for looks and performance, I've noticed my Fiesta drives a LOT better. With a twin straight-tip muffler that was installed, the acceleration is both faster and smoother with the new muffler vs. stock muffler. I couldn't believe the length and size of the stock muffler - it's nearly twice the size of most mufflers I've seen on vehicles nearly twice the size! For the price ($200), the modification was well worth it!

Wow I'm pretty surprised to see so many other people are dealing with the same issue! I got my 2011 Ford Fiesta one week ago exactly. It was a gift so it was purchased from a dealership about 5 hours from where I live and go to school. I had it for 2 days, and started to notice it really seemed to struggle in stop and go traffic. It felt like the transmission couldn't figure out if it wanted to shift up or down. It was subtle at first so I didn't really think much about it.

Then the following day I had to drive back home for school. I drove it for 5 hours, then when I got back to Baltimore, it was the middle of rush hour, so I had to sit in stop and go traffic. Thats when I knew something was wrong. It really had a hard time shifting through the low gears during the stop and go, until finally it actually STALLED OUT on me a few blocks from my house. I had to brake suddenly, and when I gave it a little gas to recover, it shook violently, puttered, and cut off! I was devastated! :(

I took it to a local dealership and they told me they couldn't find anything wrong with it. They explained its not so much an "automatic" (which I'm used to driving) but an automated manual (which I've never driven before). They said they would reset the computer and over the next week or so it would "learn" my driving style. I was told not to give it a lot of gas right away.

So I've been driving it EXTREMELY carefully, but I'm still having similar issues. Of course it has not stalled out again, but it's super sluggish through the low gears in regular city driving.

I got the car so I could have something small and gas efficient for city driving. Was this a mistake? I'm contacting my dealership tomorrow to ask about this whole transmission fiasco.

You are lucky. I had to pay for the new transmission on my Toyota Matrix. It was even a manual. No company is perfect. The problem is this is an all new design for Ford, not just a new transmission. We're the real world experiance for the transmission. Google transmission failures for Honda minivans and Toyota Matrix. Cracked engine blocks for Honda Civics. Any car is a gamble. Good luck.

So I took my Fiesta back to the dealership, and they kept it ALL day doing a thorough inspection to see if anything is "wrong" with the transmission. I just got a call from the Service Tech, and he said he drove it around in traffic to replicate my complaints, and that something is definitely wrong. But, I guess the computer isn't throwing any "codes" so they don't know how exactly to proceed. He called some higher ups at Ford who told him nothing is wrong and kind of blew him off.

But like I said, he's not confident in the vehicle and is keeping it to do more work and try to figure out how best to proceed. The master technician is coming in on monday to look at it, and hopefully they will either replace the transmission, or switch me into a new car (since it falls under the lemon law).

My biggest fear at this point is that replacing the transmission with a "new one" wont fix the issue, because the car will still be using this "automated manual" technology. Ford really needs to get on it and release a software update, or just go a different route with their transmission engineering. I wish I had realized prior to purchasing this car that it wasn't an automatic transmission in the true sense... has anyone else heard back from their dealerships about this?

I have a 2009 Fiesta and have had nothing but trouble witht the transmission. It broke down on the way home from the dealership-it went into safety mode due to a transmission error. When it was towed back to the dealership they said it was a computer error and it went into safety mode just to be safe. About 2 months ago I noticed that it was struggling to accelerate between 2nd and 3rd gears, especially when going up hills. I drive 100km a day to and from work so I know my car well and knew something wasnt right. I took it to a dealership near work and they said nothing was wrong. Then exactly 2 years and 1 week after purchase it broke down on the way home from work, with the error message Transmission failure service soon. Servicing soon was not an option as it would not go over 60km/h. It had to be towed back to the dealership. They were unable to fix it there and said it would have to go to a 'head office' type of Ford. After a week I could get my car back. The local dealership admitted that there were numerous error messages, hence why they had to send it to the next place. However the main Ford people said that there was nothing wrong. They took the transmission appart and said there was nothing. I am now not comfortable driving my car to new places because I dont want to break down in the middle of nowhere! I can still tell that there is something wrong with the transmission. It still struggles fromm 2nd to 3rd and often will just jolt into the next gear-making it a very unpleasant drive. So it looks like it isnt jsut the 2011 Fiesta that is having issues. Maybe it is all Fiesta's.

Has anyone been able to get their's fixed properly or some answers from Ford that make sense. Because I am sick of being treated like an idiot. I know there is something wrong with my car.
