2019 Ford Fusion Hybrid SE. Vehicle experienced a “Stop Safely Now” warning with hybrid system shutdown, occurring both while driving and while parked/idling, causing jerking symptoms. This puts driver and other roadway users at risk, as loss of power/propulsion can occur without warning while in motion. Vehicle also set a P0073 (ambient air temperature sensor circuit high) fault code. The ambient air temperature sensor was replaced (Ford part numbers AU5Z-12A647-B / FC4Z-12A647-A) but the underlying issue has not been fully resolved and diagnostics are ongoing. Vehicle also had a prior transmission replacement (January 2023). Vehicle has also had extreme, unresolved electrical issues: fuses repeatedly burning out, lights burning out, two horns replaced due to failure, backup camera display turning blue/failing, and dashboard warning lights randomly illuminating. The dealership has confirmed electrical issues are occurring but has not been able to identify the root cause despite inspection. Issue has been confirmed/reproduced by a dealer. Vehicle and components are available for inspection upon request. Exact onset date of symptoms is UNKNOWN, but warning lamps and jerking preceded the “Stop Safely Now” shutdown events.* problems have been ongoing since purchase of the vehicle in 2019. Ongoing still in 2016

NHTSA complaint #11623417 — an unverified report by a vehicle owner.
Coolant leak issue that caused the check engine light to turn on. This defect is present within these 2019 Ford Fusion Hybrids with EcoBoost engines. My safety and the safety of my passengers was put at risk since this defect can cause coolant to leak into the cylinders, leading to corrosion, misfires, engine failure, and even potential car fires. My mechanic gave it a diagnostic check and the following issues were detected: Random Misfire Detected- Not Current DTC, Cylinder 2 Misfire Detected- Warning Lamp On, and Misfire Detected on Startup (First 1000 revolutions) - Pending DTC. He also noted that the coolant level was low. I reached out to my local Ford service department and they wouldn't assist me with this serious concern.

CVT Transmission Vehicle purchased 4/15/19 with 38,000 miles Transmission was bad and was replaced under warranty by Ford on 8/13/2021 @ 77,099 miles. Noise is back and I took vehicle to dealer for diagnosis 10/10/2023. Diagnosis: Hybrid Electric Unit Motor went out/Transmission is bad and needs to be replaced @ 115,023 miles I have only driven the car $67,076 on this new transmission. This does not seem right. Dealership says I am out of "dealer warranty" and that I must pay out of pocket $7k
NHTSA complaint #11549455 — an unverified report by a vehicle owner.
Engine makes a whining sound when motor engages. 2 auto shops, including Ford dealership says it's a bad transmission. When I went online to see if others have had this problem, issue was confirmed that this is a common problem with this Hybrid. We bought this car brand new, have maintained it per manual at dealership. This should not happen with a car with only 112,000 miles. Lemon law?

What component or system failed or malfunctioned, and is it available for inspection upon request? -Engine/Coolant System How was your safety or the safety of others put at risk? -Coolant is being drained by engine. Subsequently, the coolant is going in to the engine, causing overheating, and potentially, a fire. Has the problem been reproduced or confirmed by a dealer or independent service center? -Yes, I have the repair estimate. There is a class-action lawsuit in California over this issue Case No. 2:20-cv-01796-TLN-CKD Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -Same as above Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

NHTSA complaint #11536863 — an unverified report by a vehicle owner.
On May 26, 2023, after I started moving from stop at a traffic light, I rear ended the vehicle in front of me when it came to a sudden stop. My speed was between 25 - 35 mph at most. My front and side curtain airbags deployed, the hood was crumpled and fascia was damaged as expected. However after 10 minutes or so, flames started coming from underneath the hood and within a few minutes the engine compartment was on fire. The Fire Department arrived and put out the fire but had to break the windshield and rip off the fender to aim the fire hoses.

Car has 89,900 miles on it. Has been serviced every 5k miles. Never had an issue. And then last Friday the car started making a rattling sound under the hood. So I pulled over. No warning lights whatsoever was visible. I turned the car off checked everything and it all seemed fine. I turned back on the car and heard nothing. So I began to drive and after 2 mins the noise started again and now a warning ⚠️ light appeared and stated to pullover safely. I had it towed to shop only to find out that my engine was blown!
NHTSA complaint #11519082 — an unverified report by a vehicle owner.
My FordPass app told me that the vehicle detected a misfire. So we took it to the auto shop to get an official diagnosis, and was informed that coolant is leaking and causing a misfire. They said it is a known issue in ford vehicles, yet there are no recalls or fixes for it. If the auto shop is unable to resolve the issue by replacing a seal, we will then have to have the engine replaced. If this is a common issue, then ford needs to open a recall and fix it. It is my main vehicle that I use and I have my 6 and 8 year old with me 99% of the time and would feel much safer knowing the issue is resolved
