“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…”

“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.”
“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.

“OM SUNDAY MARCH 28,2021 MY HUSBAND AND I ATTENDED A AUTO AUCTION. WHEN THE DEALER BROUGHT OUT A 2012 FORD FIESTA. BEFORE BIDDING STARTED EVERYTHING LOOKED AND SOUNDED ALRIGHT. WE ENDED UP PAYING $3200.00 FOR A VEHICLE THAT THEY FAILED TO PROVIDE FAULTY PROBLEMS. CAR HAS A LIEN ON IT. AFTER DRIVING OFF THE LOT I CAME TO A RED LIGHT WHEN IT TURNED GREEN THE CAR STARTED SPUTTERING LOOSING FUEL AS WELL AS ACCELERATION. I THAN PULLED INTO THE A PARKING AT THE GAS STATION TO SEE WHAT WAS GOING ON. AND TO MY KNOWLEDGE IT WAS THE TRANSMISSION MAKING NOISE AS WELL AS SLIPPING, SPARK PLUGS, OIL CHANGE. I THEN DROVE BACK TO THE CAR BUT EVERYONE WAS GONE FOR THE DAY. I TRIED CALLING THE OFFICE THE NEXT DAY AND LEFT MESSAGES. NO RESPONSE WHAT SO EVER. THE GIRLS ARE REALLY UNORGANIZED AND SHOULD TREAT OTHERS THE SAME YOU WOULD TREAT THEM. I AM WRITING THIS LETTER TO INFORM EVERYONE I WAS SOLD A VEHICLE THAT SHOULDN'T HAVE BEEN ON THE ROAD. I WAS ALSO TOLD TODAY 4/5/21 THAT ON MARCH 5TH A LIEN WAS FILLED OUT AND TURNED IN. I'M REQUESTING THE AMOUNT I PAID FOR THIS LEMON LAW VEHICLE ALONG WITH COMPENSATION FOR GIVING FALSE INFORMATION.”
“MY TRANSMISSION CONTINUES TO SLIP REPEATEDLY AFTER I TOOK IT TO FORD WHERE THEY TOLD ME NOTHING WAS WRONG AND THAT I DIDN'T KNOW WHAT I WAS TALKING ABOUT . THEY WERE RUDE AND INCONSIDERATE. IT HAS SLIPPED IN ALL FORMS OF MOVEMENT . WHEN I'VE BEEN BRAKING ,DRIVING URBAN OR HIGHWAY. I TOOK IT BACK TO A DIFFERENT DEALER SHIP AND THEY TOLD ME MY TRANSMISSION WAS BAD.”
