What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I am filing a safety complaint regarding my 2021 Ford Bronco Sport 1.5L and Ford Motor Company's handling of recall-related repairs. Beginning October 22, 2025, I repeatedly attempted to have the applicable recall work completed through two authorized Ford dealerships. The programs involved include: • Recall 24S24 – NHTSA 24V267000 • Customer Satisfaction Program 22N18 – NHTSA ID 10233848 Despite multiple dealership visits and Multi-Point Inspections, the work was not completed until November 4, 2026. During this period, my vehicle experienced significant loss of engine power, particularly when traveling uphill and at higher elevations. Powertrain warnings also appeared, creating potentially dangerous driving conditions, especially on highways where maintaining speed is critical. The vehicle is now experiencing a failing turbocharger and other major mechanical problems. My concern is that these issues were overlooked or not properly investigated during previous dealership inspections. Had the necessary work and inspections been performed in a timely manner, these problems may have been identified before my 60,000-mile factory warranty expired. I am now facing…”

“Continue to have major safety concerns over this car. Had new issue of car not starting after refueling. Brought it in to dealership on Friday 9/25 and check engine light indicated EVAP problem code. Dealership at first refused to evaluate EVAP telling me was not related. Then then found a clogged hose but did not repair the EVAP and on 09/28 my check engine light came back on again. I called dealership and ford corporate still with no plan as they say they will not cover repair or rental. This is in light of having had the car turn off spontaneously while driving as recent as December. I am very concerned this may be linked to fuel injector recall which has no remedy and do not feel safe driving this car.”

“My vehicle is subject to open NHTSA recall 25S76 regarding a fuel injector that may crack and cause fuel to accumulate on top of the engine near hot surfaces, creating a fire risk. This recall was identified months ago, but Ford has stated parts are not currently available and no repair date has been given. I have not received any further communication or updated timeline since the recall was issued. In the meantime, my vehicle has also been experiencing intermittent jerking during acceleration between approximately 40-50 mph, which I am concerned may be an early symptom of the injector issue described in this recall. I am continuing to drive the vehicle because no remedy is currently available, but I am concerned about the extended delay in providing parts for a safety recall involving a known fire risk. I am requesting that NHTSA review the length of this delay and Ford's plan for remedying affected vehicles”

“The contact owns a 2021 Ford Bronco Sport. The contact stated that on several occasions the vehicle lost automotive power while driving and while stopped and idling. The check engine warning light was illuminated. The contact stated that after refueling, the vehicle required several restarts before continuing to drive. The vehicle was towed to a dealer to be diagnosed, and the contact was informed that the battery was prematurely draining and that the EVAP was clogged, and that the battery and EVAP needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 35,000.”

“After refueling car the car will not start after several attempts. Brought into ford dealership they said they cannot locate issue. They said have a small EVAP leak but would not repair unless a large leak and this would not cause an issue, but online this is exactly the cause of this problem. Additionally now 3rd battery to replace in only 5 years and they claim this is normal. In the past this car has spontaneously turned off while driving as well.”

“On 9/15/26, while actively driving with my child, the monitor screen suddenly turned black and an error message of "Vehicle Network Communication Error", a few seconds later my dashboard turned black, no display messages, speed limit, or manual gauges were working and that too went blank; blinkers did not work when trying to use them. Luckily I was a short distance from where I was traveling to and when we arrived I turned off my car to see if i restart it, it would reset my car. It did not work. My car did not turn on, did not crank- the light on my start button just flashed rapidly. It was not until after my husband later arrived he disconnected the negative battery terminal and let it stay disconnected for 20-30 minutes and it then restarted. Case #CXH-09342591-W5K1G2 was filed with Ford Customer Relations, but they said further information regarding the case would likely not be provided to me as an update.”
