2017 Ford Focus: check engine light

Filed Oct 19, 2026 · Engine · FL

I had a recall on my vehicle in June of last year for a new motor. I had oil leaking all in my intake. I didn’t get my car back till December with a new motor. As soon as I left the check engine light came back on. I took it back and they said it was my battery. Now my oil is leaking all in my intake again. I haven’t put 12000 on the motor and that’s the warranty. My car was repaired incorrectly. The dealership shows no interest in it. It’s been there since 10/14/2026 and at first they said it was my battery again and my fiancé demanded them to look closer at it then they called about my oil leaking everywhere again. I haven’t received a call since.

What component or system failed or malfunctioned, and is it available for inspection upon request? Transmission failure after 2 recall/warranty repairs, most recently in July 2026. How was your safety or the safety of others put at risk? Vehicle accelerating and then stopping out right on and off the freeway "bucking" on the freeway, fast then slow, with no foot on the accelerator. Has the problem been reproduced or confirmed by a dealer or independent service center? This was immediately noticed when we picked up the vehicle from the dealer after the 2nd Ford recall repair. No, they deny this, and state this is a coincidence when it was not doing this when we dropped the vehicle off to them. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, but I will be getting police, lawyers and insurance involved since Ford motor company will not help us. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Check engine light and service engine now light on when we picked up the vehicle from the Ford dealership on July 13th, 2026. The day we picked it up, immediately this happened pulling out of the dealership/service department, and on the freeway, 4 times causing close to 4 accidents.

I am filing this complaint regarding a severe safety hazard and prolonged failure to resolve an official recall repair by the manufacturer and dealership. In April 2026, the vehicle was brought to the dealership for an official recall repair. The repair was delayed for 2 months. In June 2026, after the dealership confirmed completion, I retrieved the vehicle. While driving on the highway, the check engine light suddenly illuminated and the vehicle completely lost power. Pressing the accelerator pedal produced no response, leaving the car unable to accelerate in active high-speed traffic. This created an extreme safety risk that nearly caused a severe highway collision. The vehicle was towed back to the dealership. The dealership returned the vehicle a second time, claiming it was repaired, but the exact same check engine light illuminated immediately with the same loss of power, requiring another tow. As of August 2026, the dealership has retained the vehicle for over 4 months in total due to backordered parts, without providing a clear completion date or loaner/rental transportation support. The dealership and corporate customer care are currently ignoring attempts to communicate. The recurring loss of engine power on the highway and unresolved recall defect pose a direct and imminent risk to public road safety. The components involved are currently at the dealership for inspection.

While driving approximately 53 mph on a main road, my 2017 Ford Focus suddenly displayed the message “Engine Fault Service Now.” The vehicle immediately entered limp mode, downshifted into 2nd gear, and would not accelerate above approximately 31 mph. During the event, the engine shook noticeably and made abnormal noises. No check engine light appeared during this initial incident. This problem occurred multiple times over several days, most often when the fuel tank was below approximately half full. Each time, I was able to temporarily restore normal operation by shutting the vehicle off, waiting about one minute, and restarting it. After restarting, the vehicle would drive completely normally until the problem occurred again. A few days later, while sitting in my vehicle during a work break, I started the engine and it immediately entered limp mode without being driven. A check engine light then illuminated, and the engine stalled shortly afterward. The diagnostic trouble codes retrieved were: * P1674 (Stored, Pending, Permanent, and Enhanced) * U0100 (Enhanced ABS Code) A mechanic familiar with Ford vehicles suggested the symptoms could be related to the EVAP canister purge valve issue that has been investigated on similar Ford Focus models. He recommended keeping the fuel tank above half full as a test. Since keeping the fuel tank full, the limp mode condition has not reoccurred. I took the vehicle to a Ford dealership to have the purge valve issue evaluated. The dealership declined to perform any purge valve-related repairs because they believed the problem was transmission-related and stated the engine issue would need to be repaired first. I am submitting this report because the vehicle unexpectedly loses power while driving, creating a significant safety hazard when traveling at normal traffic speeds.

Recall maintenance with regard to the federal safety agency ID Number: 19V515000 for a Purge Valve was completed 1/9/2025. Starting in October 12, 2025, driving on the freeway, a large "bang" was felt/heard. I pulled over, the dust cover under the car had ripped partially off and took a portion of my grill trim with it. The car still ran perfectly fine, so I continued the mile and a half to my house. I did not see anything that I may have hit on the highway and did not see anything eject behind my car when this incident happened. I noticed the oil light begin to flicker as I was ½ mile from home for maybe a second, then it was off and then flickered again, it did not stay lit. I filed a claim with my insurance-Progressive-they wanted to total my car without inspecting it. I negotiated and they had me take it to The Ford dealer who inspected it visually to see if the cause was internal combustion as my insurance claimed, or external damage. See photos. They recommended a full engine replacement after only a visual inspection and charged me $276.70. I had the oil-pan replaced as shown on my bank statement $1053.77, with Interstate Automotive who verified no engine damage was found. Next the LCD instrument panel showed distorted, or not at all, or perfectly fine at times, which made it hard to read, and no instrument warnings are given for any issue, just the check engine light. As of today, 3/10/26, car will no longer reverse or progress into 2nd gear, is sluggish and feels as though it has no power at all. This happened randomly on 3/9/26 after the car would not start and it was believed to be a battery issue. The battery was replaced 3/9/26 $148.08. When the diagnostic codes for the check engine light were tested, they showed a faulty CO2 module issue. New parts will be installed on 3/11/26. All of the above described issues seem as though they could be related to a major safety issue with this vehicle, but Ford insists any courtesy fixes are not available to my VIN.
