2020 FORD EXPLORER Complaints

I have recently have experienced engine failure with the 2020 Ford Explorer 2.3 ecoboost engine. I was driving on a 4 lane highway, specifically on a bridge, and I experienced loss of power and acceleration. At that time, the engine light came on. I managed to get home, with the vehicle seemed as if in limp mode. I had my vehicle towed to the Ford Dealer ship. The service manager stated that they believe it is complete engine failure. He believes the failure is in the cylinder walls which is due to coolant intrusion in cylinders 2 and 3. His suggestion is to change the "long block" at the costs of $12,284,51. Also, he expressed a concern with the transmission. It might be an issue with the computer, or wire harness. Which would be $1091.81. Plus, a couple sensors, spark plugs. In all The total repair costs are $16,904.16. I owe about $9,500. Prior to this, in 2022 the Turbo went out. It was replaced under the warranty at that time. This was at 90,000 miles. After doing some online research. There has also been a class-action lawsuit involving the 1.5L, 1.6L, and 2.0L EcoBoost engines. Owners of these engines reported issues such as coolant leaks leading to engine overheating and, in some cases, engine failure. The lawsuit claims that Ford was aware of these defects but did not take adequate steps to address them. There are some fantastic videos on youtube that explains and illustrates the reasons for the manufacture defect and engine failure. [XXX] I am a high mileage driver of highways and interstates. I understand that vehicles will have normal wear & tear. I now have 190,000 miles and no longer under warranty. However, based on my investigation, and other similar complaints about the 2020 Explorer with the same or similar issues, I believe there could be a defect with the Cylinder head just like the other ecoboost engines. Other ford explorer owners will likely experience the same as the add miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX], with the wife and 3 grandkids in the car, as we made a left turn and were picking up speed suddenly the car downshifted to first gear. This jerked the whole car whipping the necks of everybody in the car and drastically slowed the car. Fortunately, the guy behind me did not rear end me, but almost. This scared us all. The car recovered and we proceeded the 15 miles home but several times the transmission seemed to have trouble finding the right gear. There were no lights or warnings on the dash. My wife said she would not drive the car any more. We parked the car until Monday, January 6. I drove the car to Tracey Langston Ford in Springfield and they have said I need a new transmission. This is a $6,700 repair out of my pocket. They have said they will reduce it to $6,000. Meanwhile, I still do not have the car and we have made it with one car for over 2 and one half weeks.

Cracked Transmission Cooler where hoses attach. Replaced/repaired at owners expense.

The transmission failed. Causing me to almost be rear ended because when I hit the brakes there was a hard down sift between gears. Then I could not accelerate resulting in me being stranded on the side of the road. We have had the car inspected by two separate shops and they both confirmed it was a failed transmission. We were not able to take it to the manufacturer dealership for two weeks. There was no warnings before this happened.

1. Yes, available for inspection. 4 x 4 issue. Front half shaft axel needs replaced, as well as hoses because of the change in the front half shaft design. My safety is at risk as when I'm driving the veichle it will randomly kick out of 4 x 4, and hill assist. I cannot make it up hills and slide everywhere. I have almost been into multiple accidents due to the failed system. Ford Dealership inspected the car, and diagnosed it. They said it's a known issue for the year and there is a TSB but no recall. They fix the sams issue frequently. Ford Dealership read the codes and wrote a order of the parts I need. No lights or issues prior to this safety issue. This issue causes all sensors to stop working, hill assist to kick out, auto hold to kick out, and causes the entire car to not work in 4 x 4.

At only 5 years old and at 113k miles in January 2025 I was told by my local dealership that the right side catalytic converter was cracked and needed replacement to pass inspection. In March 2023 the left side catalytic converter was replaced under a service bulletin 21E11. Prior to that both sides intermediate exhaust pipes and flex connectors were replaced in November 2021. I have searched online and read of many other Ford Explorer ST owners complaining of failed catalytic converters. Ford is doing nothing to address this if the vehicle is outside of the required 80k mile emissions warranty. It seems to me there’s a known problem and this ride side catalytic converter should also be recalled. No catalytic converter should be consistently failing this early in a cars lifespan. Catalytic converters are known to last over 10 years and 300k+ miles. I’ve also seen where the same Ford Explorer but under the Police Interceptor name has had the right side catalytic converter recalled.

While driving. Every light on the dash started coming on. Pre-collision assist not available, 4wd fault not available, no cruise (adaptive or regular) available, reverse break assist not available, hill assist not available. Every time the vehicle was started it would these issues or would start while driving. This is an absolute safety issue and hazard. The vehicle has plenty of reports online of this happening to other. Ford was willing to give vehicle back saying it was safe to drive without fixing bc I couldn’t afford it and it wasn’t covered under the power train warranty. I was told I have to report it and if it gets enough reports something will be done. But this is an unacceptable answer and cost for something that is a safety concern.

2020 Explorer ST transfer case and transfer case module failed. Safety was a high risk factor for myself and anyone around me because when trying to make turns the vehicle slow way down like the brakes were being applied and the vehicle would violently shake. The vehicle has been inspected by a dealer and confirmed to be the transfer case and transfer case module. When this occurred there were several warnings, advancetrac fault, hill start assist fault, 4WD fault, ABS fault, and traction control fault.
