Check engine light on, engine is sluggish when accelerating especially from a stop. Cam phasers malfunctioning causing rough idle and issues with accelerating. This has posed a major issue when attempting to pull out into traffic and not being able to accelerate ahead of incoming traffic. Engine has actually stopped at intersections, while going through car wash, at a stop.

2019 F150 with approx 62,000 miles on the odometer. Primary concern is the transmission was unable to shift gears normally. The truck was unable to accelerate or maintain speed normally while the automatic transmission attempted to change gears. This failure occurred without warning. The failure of the transmission was verify by the dealership and an independent mechanic. After the initial failure the "service vehicle" and "check engine" lights came on. After the initial failure the truck was unable to shift into gears 7-10 and had delayed shifting in lower gears. I am lucky the initial failure happened on a residential street at speeds less than 35 MPH. If this had happened at a different part of my commute I could have caused an accident turning into an intersection where cross traffic doesn't have a stop sign.

Transmission Gear Failure VEHICLE: 2019 Ford F-150 MILEAGE: 67,000 ​Description of Incident: I am reporting a catastrophic internal mechanical failure of the 10R80 transmission. While driving, the vehicle emitted a strong, pungent odor of burnt transmission fluid followed by a total loss of gear engagement. The failure was sudden and occurred without a "Check Engine" light or warning, leaving the vehicle stranded in a dangerous position in active traffic. ​Technical Assessment of Cause: Upon professional teardown, it was determined that the internal gear sets were severely damaged and required full replacement. The transmission fluid was heavily oxidized (burnt), and the planetary gear assemblies showed signs of extreme thermal distress and mechanical chipping. This indicates a failure of the internal lubrication system or a structural defect in the gear hardening process, leading to metal-on-metal contact and total component failure at only 67,000 miles. ​Safety Concern: The suddenness of this gear failure creates a significant risk of a "stalled vehicle" scenario in high-speed environments. Furthermore, a mechanical gear failure carries the risk of internal components fracturing and potentially locking the rear wheels, which could lead to a complete loss of vehicle control. This is a premature failure of a major powertrain component that is advertised to last the life of the vehicle.

After a recall repair was performed on my vehicle at Central Ford on 3/5/2026, the check engine light came on right afterward. Since that time, I have returned the vehicle to the dealership for repair on three separate occasions. My vehicle is still at the dealer now. The dealership has had my vehicle for a total of approximately seven weeks across these visits. Despite multiple repair attempts, the issue has not been resolved, and the check engine light remains on and continues to return the same day the dealer claims it has been fixed. The dealership has been unable to provide a permanent fix or clear explanation for the ongoing problem. I am concerned that the recall repair was either performed improperly or has resulted in a new defect affecting the vehicle’s reliability and potentially its safety. At this point, my vehicle remains unreliable and may not be safe to operate. I am requesting that this issue be investigated, as the recall remedy appears to be ineffective in my case. Repair history and documentation are available upon request.

I own a 2019 Ford F-150 equipped with the 3.5L EcoBoost engine. The vehicle has developed a loud rattling noise during startup along with an illuminated check engine light. The vehicle was diagnosed by Family Ford of Enfield as having a failure in the timing system, including cam phasers, timing chain, tensioners, and guides. The estimated repair cost is approximately $5,000. This issue appears to be a widespread and well-documented problem affecting 2017–2020 Ford F-150 vehicles with the 3.5L EcoBoost engine. The failure of cam phasers and timing components can lead to improper engine timing, rough operation, and potential engine damage. I am concerned that this condition could worsen over time and potentially lead to engine failure while driving, creating a safety risk. Despite this being a known issue, no recall or adequate assistance has been provided. I am submitting this complaint so that this recurring problem can be investigated further for potential safety implications and manufacturer responsibility.

My 2019 Ford F-150 (2.7L EcoBoost) is subject to Emission Recall 24E12, which addresses a defective PCM calibration that Ford acknowledges "could, over time, reduce the effectiveness of the emissions control system and the monitoring accuracy of the catalytic converter's efficiency." COMPONENT: Catalytic converter system and powertrain control module (PCM). Vehicle is available for inspection at Rich Ford in Albuquerque, NM, where it has been serviced for this issue. TIMELINE: Prior to the 24E12 recall repair, my truck had intermittent P0420/P0430 codes (catalyst efficiency below threshold). The check engine light would illuminate and then clear on its own. I brought the vehicle to Rich Ford for the 24E12 PCM reprogram. Within approximately one month of the recall repair, the same catalytic converter codes returned, except now the condition is constant and no longer clears. This timeline is documented in my FordPass app and the dealer's service records. SAFETY RISK: The constant check engine light prevents the vehicle from passing Bernalillo County emissions testing, which is required for registration in Albuquerque, NM. I am unable to legally register my vehicle due to a condition caused by a manufacturer-acknowledged defect. DEALER CONFIRMATION: Rich Ford diagnosed the recurring P0420/P0430 codes. They initially attempted to charge me $300+ for extended diagnostics. They are now consulting with Ford about whether a catalytic converter replacement will be covered under the recall. PRIOR SYMPTOMS: The intermittent check engine light with P0420/P0430 codes existed before the recall repair but was not constant. The recall repair worsened the condition from intermittent to persistent. PATTERN: Ford's recall documentation states the MIL "may illuminate even though a catalytic converter repair may not be necessary," yet numerous owners report being quoted $1,900-$2,100+ for cat replacement at their own expense after the 24E12 reprogram. Ford corporate confirmed the $300
