2015 Ford Fiesta: check engine light

Filed Apr 27, 2026 · Engine, Steering · WA

I was driving for couple hours then my oil light came on check engine light came on. Vehicle started to shake very badly. I had to pull over and see what happened. I started the vehicle up again and the oil light and check engine light are still on. I know that these vehicles have the wet belt system on the automatics. But they don't have one for the manual transmission. There should be a recall for these just like the automatics.

In May, my 2015 Ford Fiesta SE went into "limp mode" before reaching the speed limit of 25mph. Immediately afterwards it was taken into a local shop, Mobile Mechanic, where no codes were active and coolant level was between min and max level. Next day, car experienced misfiring check engine light and overheating before being looked at by a mechanic. Mechanic replaced spark plugs due to code reading misfiring in cylinder 3. Car still continued to misfire and due to slight lower level of coolant, Engine overheated and cracked a cylinder block in the 1.0-liter three-cylinder EcoBoost engine. This car is used to travel with two children under [XXX] and [XXX]. The beginning of June the car overheated on a hot day traveling home with the two kids and myself. We had to sit in the heat for close to an hour before temperature gauge returned to normal, I checked the coolant and it was still between min and max levels. On the same trip, it was on the verge of overheating again due to climbing the hill before our house. After finding out the cylinder block was cracked by my mechanic we discovered there has been a recall issue with the same engine, Recall 17S09, that began in January 2018, a month before I purchased my car from Redwood Ford in Ukiah California ([XXX]). I called W. C. Sanderson Ford in Healdsburg, California on July, 15th, 2025 to see if it would be possible to see if this recall was actually fixed on my vehicle, which they responded that the recall has nothing to do with my car and they can't do anything about my car. The representative specifically said that due to my car being 10 years old it has been disqualified of the recall and is no longer attached to my VIN. I have taken this car to the same local mechanic 4 times since the ending of May, 2025 for the same issues before we discovered the cracked cylinder block, mechanic took pictures of fluid and water inside cylinder 3.

The transmission control module (TCM) on my 2015 Ford Fiesta was failing at 81,000 miles. It was difficult to accelerate the car even at low speeds (25-30 mph) and my check engine light was on. I took my vehicle to the nearest Ford Dealership (Big Star Ford in Manvel, TX) who assessed my vehicle and determined the TCM needed to be replaced. They replaced the part but told me it was not under the 14M02 warranty. My check engine light did come on once back in May and the car was struggling to speed up but when I took it to a car shop the check engine light was not on and the mechanic said it was fine.

Ford Dealership determined the TCM is the culprit for my transmission issues. The check engine light is illuminated. Car revs up but goes no where. There is an active extension warranty issued by Ford but for some reason my VIN is not included.

I’ve owned my 2015 Ford Fiesta for about 7 years now. Within the first year, I contacted the Ford dealership explaining noises when driving and my dual clutch shifting gears. I sent them video sound recordings. They said it was typical of this transmission. The car has never felt smooth but “ok enough,” until 18months ago when I reported gears slipping. No error codes were detected but parts of my clutch were replaced. Now, 16,000 miles later I brought my car into ford dealership saying I felt the gears slipping. They diagnosed a few other maintenance pieces like brakes and tires but said nothing was detected with the transmission and clutch. 3 weeks later, I was driving on a highway - lake shore drive in chicago, and my check engine light came on. My car would not change gears or accelerate past the 30mph I had been going. I felt like I was in neutral. I exited, fearing an accident. In stop and go traffic I used my hazard lights because I could not accelerate at each stop sign. I made it to a safe spot to pull over and then realized i could not reverse! I had my car towed to the ford dealer from 3 weeks prior. At this point they could read a few clutch error codes but cannot be certain of the actual cause. In order to do so, they need my consent of a possible $1500 service charge for investigating the issue. Ford costumer service line has said “oh wow, we’re glad your weren’t in an accident. I’m Sorry, your car does not meet criteria for any support from Ford.” Ford has knowingly kept these faulty transmissions on the road and now they are telling me that they will not help look into my vehicle’s transmission and safety issues. This seems unreasonable when the issue is clearly linked to the faulty dual clutch Powershift system. 1.5 million Ford Fiestas may still be registered and driven with Ford offering nothing other than “I’m really glad you dodged an accident and made it off the highway.”
