1 Software problem

Failure Date: 10/02/2021

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.

2 Software problem

Failure Date: 08/10/2020

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. If the cpv malfunctions and sticks open, it can lead to excessive vacuum in the fuel vapor system, potentially deforming the plastic fuel tank. This can cause the following symptoms: illuminated malfunction indicator lamp (mil) with certain diagnostic trouble codes (dtcs) inaccurate or erratic fuel gauge indication inaccurate distance to empty (dte) engine stall and/or other drivability concerns related to stuck open cpv safety risk this may result in an engine stall while driving without warning or without the ability to restart, and can increase the risk of a crash. I now have 2 auto loans im upside down on for recalls that I cant even get my car to Ford because I cant afford the tow. I pay over $500 monthly for lemons.

3 Software problem

Failure Date: 06/16/2017

Lost power while driving, problem occurred 4 times in the span of driving 10 miles, struggled to get home. Occurred while on freeway, at red light, and high speed or slow speed did not matter. Car would ding the alert sound, several warning lights would flash, and I would be immediately be forced to coast to the side of road each time. Three instances posed serious risk to others as my car lost momentum before safely making it off the road, and other cars had to move around my car. Problem matches the manufacturer communication below from 2015, which means this has been a long term design flaw. This needs to be marked as a safety recall. Nhtsa id number: 10058725 manufacturer communication number: sb-15b22 summary on certain vehicles, transmission control module (tcm) had developed electrical circuit failures, resulting in an intermittent transmission engagement loss while driving or a lack of power or no start and software needs to be replaced.
