2012 ford fiesta check engine light on codes reading o2 sensors, catalytic intake, misfires, fuel injection, etc. I have had my fiesta at 3 mechanics all very known for there reliability all diagnosing it different issue recommending me to go to dealership which I was turned away because the recalls for the vehicle isn-€™t an issue for any of the possible diagnostics. Single mother of 3 now no vehicle, no money and no way of providing without transportation. Less than 150,000 Miles owned less than two years and the amount of money put into the vehicle ford should be ashamed. Shuddering and accelerating issue was told clutch and transmission issue but no help or actual known diagnosis since ford won-€™t diagnose the suspected diagnosis from any of the mechanics I have taken the vehicle to and they can-€™t for sure diagnose it until ford confirms the diagnosis since this is a known issue. They also sent me two recalls but refused to fix the recalls because I wasn-€™t 100% sure my vehicle needed the repair and threatened to charge me 150 diagnostic charge for the recall after I already poured my heart out to them about the issue I can-€™t seem to even get repaired due to there lack of care care as a manufacturer

Transmission Malfunction, this is the 4th time that I am having to replace the transmission. I am taking the car back to dealership to get the transmission fixed for the 5th time. The car jerks when it comes to a stop. Hard time accelerating or does not accelerate. I put the car in R and it did not budge at all, even turned the car off and turned it back on same thing. This car should not be permitted on the road. Does not shift gears properly, the RPM run very high. I am afraid to drive this car constantly, even after I get it out of the shop because I just know that the transmission will eventually malfunction on me again. Very unsafe and unreliable to drive.

My engine light came on so I took it to Ford dealership and they told me it's the car computer not understanding when the engine is turned off and that it is not an urgent issue to keep driving it since they are backed up. A week later while driving the car just stopped the engine light started glitching. After 2 minutes it starts again. So I called Ford explained what happened they could check it a week later so I start calling around. Found Ford dealership that can check it immediately, then they told me that the issue is a wiring problem that Ford has sent them a bulletin about but it is not a recall. I told them that it should be a recall if Ford knew that a wiring issue can make your car just stop in the middle of traffic with no warning whatsoever. The issue on my invoice says EEC TEST CODES P2610 P2138, PIN POINT TEST, NEED TO PERFORM TSB 13-11-15 WIRE REPAIR BYPASS CONNECTOR C210 TO PCM, REPROGRAM PCM TO LATEST SOFTWARE. It is a safety issue if your car just stops working in the middle of traffic and Ford know but refuse to issue a recall for it.

It started with a loud thud sound while driving. It was as if something hit or fell on the car. Scary loud sounds from the car used to happen randomly at anytime. I had to stop the car, get out and check what fell or hit the car but every time I checked there was no mark or scratch or sign of something hitting. Sounds were so sudden and loud that someone could easily be shocked and lose control of the car. After such repeated incidents of loud thumping sounds I thought that it was the speakers (part of cars standard audio system) that was making the sound. I thought that the problem can be temporarily solved by turning off the audio system. But it was not so. Car kept making disturbing noises even with the audio system turned off. Over time it got worse and more frequent. It scares kids and other co-passengers. Knowing how disturbingly and dangerously sudden these noises are I absolutely cannot lend my car to any family member or friend to drive on their own. They could lose control of the car harming themselves or others. Now it does long crackling, popping and thumping sounds even when the car itself is off ignition. I am holding the car keys, am outside the car, it makes crackling sounds on simply opening and shutting the doors of the car. Upon quick search of this problem on the internet I find that a LOT of people have reported having this problem - https://www.youtube.com/watch?v=WLx0WN23SD4. I along with lot of others who have reported this problem are surprised that there is not already a recall of this. There appears a related TSB but it doesn't list 2012 Ford Fiesta SE - https://www.tsbsearch.com/Ford/13-4-14. Please have Ford address this and save lives. Thank you

While my 16 yr old twin sons were driving on freeway, a loud pop of pressure release from motor occured, and steam blew out from under hood obscurring their visibilty. they were able to pull over safely and call me. Upon arrival, after confirming they were ok, I checked under hood to see that the intake manifold had built up to much pressure for the PCV hose and the recirculating hose that connects to top of valve cover. Oil had sprayed out everywhere and car will not start. Ive lost compression in 2 cylinders now from the fast overheat. My childrens safety was severily compromised by this chain reaction of a failed PCV valve. Ive since found out of recalls.This is whats stated for my 2015 Ford Focus, but happened to my 2012 Ford Fiesta Oct 22,2018 Manufacturer Recall Number18S32 NHTSA Recall Number18V735 Recall StatusRecall Incomplete Summary ON YOUR VEHICLE, THE PCM SOFTWARE MAY NOT ADEQUATELY DETECT A STUCK-OPEN CANISTER PURGE VALVE (CPV) WITHIN THE FUEL VAPOR SYSTEM.

Headlights are going out while I am driving... it's the juction box. I'm unable to upload any photos..juction box relays are corroded. This started 2019 and most recent two weeks ago.. I'm so afraid the consumer stated the vehicle was taking to the dealer to have recall repair 19B22 completed. At the time the dealer stated the repair wasn't necessary. A few months later the corrosion was found on the power supply terminal to the headlights as well as 3 other terminals. The consumer requested to have to recall repair completed under the recall.

The headlights do not work on the low beam setting. Found the headlight relay to have heavy corrosion. The front most terminal has corroded off of the relay entirely and is now stuck in the electrical box under the hood of the car. I noticed this condition when I was driving home on the highway in the early evening just before sunset. I was able to arrive at home before the lack of light caused any unsafe driving conditions. The fuse is designated R11 on the electrical box. Improper sealing of the electrical box has led to moisture be aloud in causing damages. Faulty construction from manufacturer.

My headlights stopped working and after I replaced the bulbs, the problem persisted. After further diagnostics, it was determined that my car had a corroded relay junction. It ended up costing almost $2000 to repair. I heard from the mechanic and reports on line that other people have been having the same issue for this make and model so I thought it would be worth reporting.

My 2012 Ford Fiesta has no filtration system to prevent salt and moisture from getting into the engine fuse box. Last year, a mechanic rewired the fuse box low beam relay to a different fuse, now the corrosion has started up again. This forces me to use my high beams until I have to replace the whole fuse box, which is expensive and causes me to be unsafe until I fix the problem. I've seen other instances of this online.

The exact time of the incident is unknown. I had not driven my car at night for at least two weeks before I tried to turn on my low beam head lights when I was parked in a friend's driveway at night. My car's low-beam headlights did not turn on. Upon further inspection it was discovered that the light bulbs were undamaged, but the relay had become corroded. When the relay was removed the corroded prong broke off (or otherwise remained) in the fuse box. Now there is no way to replace the relay, because of the prong in the fuse box. My low beams do not work. My turn signals and my high beams still function, but it is not safe to drive at night with only high beams. So, this is a safety issue. Below is a picture of the corroded relay prong in the fuse box. The prong is blue/green and is located in the upper left hand of the picture. Recently in Canada, there was a recall for the same problem for similar Ford Fiestas.

Due to the poor design of the fuse box located in the engine compartment, the relay (R11) responsible for switching on & off the low-beam headlights has corroded to the point that one of the pins is stuck in the fuse box & is flush with the surface of the box. Initially, this started with intermittent headlight failure--sometimes at startup & other times while driving at night or during inclement weather. The corrosion was missed when I took the car to a Ford dealership. Now, the low beams do not work at all due to the complete corrosion of the pin. This has lead to several unsafe situations. I have not been able to see & other cars have not been able to see me when my headlights stop working. I've had to drive with hazards instead of headlights at night to ensure others could see me while I moved my car from the highway to a safe parking spot. I nearly hit a deer I was unable to see due to my headlights going out while driving. From what I understand, this make & model has been recalled in Canada because they recognize the significant safety issue present. I don't understand why it is not recognized in the United States.

The low beam lights work intermittently. They shut off while driving. This causes an unsafe condition for the driver, passengers, pedestrians and oncoming vehicles. This happens both while the vehicle is stationary and in motion. It happens in all weather conditions and temperatures. It occurs both during city driving conditions and highway driving conditions. There seems to be a short between the headlight, the vehicle fuse box and the headlight on and off switch. The high beam system is not affected by this problem. Lights have been changed and fuses have been changed.

Due to moisture and debris getting into the fuse box under the hood of the vehicle, the relay for the low beam headlights has corroded and one of the pins is corroded into the fuse box. This has left me without the use of my low beam headlights. I have contacted Ford us and was told there was nothing they could do. The repair for this issue will cost approximately $1500 from the dealer for parts and labor without any solution to the sealing of the fuse box. When I called Ford us customer service and requested to speak with a supervisor regarding the issue, they hung up on my. This problem has been ongoing with 2011-2013 Ford Fiestas. This is a safety concern as the headlights just quiet working. This fuse box also controls various other critical components of the vehicle and is tied into the main wiring harness. The corrosion issues can also affect those systems as well.

Ford Fiesta 2012 has several problems with the transmission, first the car jerks around and makes a horrible noises. Then the car shuts off randomly while driving. This car is a safety hazard. Stalling and jerking around is not what a car should do. Plus both backseat latches both broke and the doors were unable to close.
