Issue with CAM Phasers when looking into the problem I noticed there was a recall for other 3.5 EcoBoost engines on other models but not on a Ford Explorer with the same engine.

Exhaust fumes entering inside vehicle when idling and driving on the road. Must drive with windows open and still cannot drive for over a few miles. Get a headache and effects lungs. Vehicle is now parked and cannot use. Exhaust is leaking near engine. Looks like a cracked manifold. Unsafe to use. Date this occurred is an estimate because I do not know how long this has been a problem. There are other 2017 models with the same issue.

Car wouldn't start. All the water had run out due to coolent leak near water pump and in finding it they found leak near front engine mount. These are problems that other 2017 explorer owners have also complained about online. In addition, Kirkland Ford stated they are backed up on repairing the toe link and roof repair due to lack of certified mechanics. The 2017 whole vehicle should have been recalled due to the cheap parts used which has caused me to continually go in to have recalls fixed. While there they end up causing more issues causing me thousands in repair bills. I have scheduled with independent car repair shop for them to give me estimate of repairing the above items for January 10 the first date they had available.

Car dies repeatedly while on the road driving and also while parked. Car has errors on dashboard when attempting to turn on, which I have a video of. First mechanic was able to replicate issue once and got some scan tool codes but he said after that, they all cleared out and he wasn't able to replicate. Car was given back to us, drove to store died and it wouldn't start in parking lot. Mechanic sent tow truck, car started when tow truck arrived. Took car to Ford, tech unable to replicate, car returned to us. Car died once again, which is when I took the error video and took the car back to Ford and showed service rep the video. Ford still unable to figure out the issue. We told Ford to keep the car because it isn't safe to drive until we find and fix the issue. Car has been in mechanic and Ford for about 4 months total.

I experienced the expulsion of coolant underneath the hood of my vehicle in the parking lot / driveways the past month or so. I took this into my mechanic and they diagnosed with water pump failure, need of timing chain assessment and 12 hours of expected labor. This issue has been recalled in Canada, but not here in the U.S. This is a significant amount of money to fix this and a safety issue as this vehicle is often driven in rural areas late at night. If inspection upon request is needed I can make it available.

The car started overheating while on my way home from a trip. I had to get a wrecker to haul it in. Ford offered no help. It was the water pump. Milage at the time was 103,000, Cost to fix $3000. So no Thanksgiving for me this year.

My 2017 Ford Explorer XLT - eco boost (72,524 miles) vehicle was misfiring (running really rough) at startup the last week or so and the engine light came on and stayed on. The vehicle was serviced in July of this year and there was no mention of the problem. Upon paid inspection today (11/10/23) and diagnosis at my local AAA Car repair service they reported the following: Engine code P0303 - no 3 misfire. The no 3 plug is very clean, which is not good (as it likely means a leak of coolant from head gasket). Upon pulling the number 3 plug, it was confirmed that there was a coolant leak from the Head Gasket. AAA car repair indicated that this was not normal for a car with this low of mileage and shouldn't happen this soon. They said they did not do this type of work and advised I check with Ford corporate to see if there was a recall or extended warranty. I called Ford Corporate, and they did not see any recalls or information that could help with the repair, and they advised I reach out to the NHTSA to see if there might be other reports or investigations underway and if not, to open one. The vehicle has only been inspected by the AAA Service garage and is now back home in my garage and available for inspection upon request. NOTE: in researching this issue on line, I did find several articles and links of videos with this problem. There are safety issues, especially when pulling out in traffic or accelerating, as the vehicle sputters and does not run smoothly or go as fast as expected and could cause an accident.?

The vehicle loses power at times. When going to another lane or pulling out in traffic, it will surge loosing power. I noticed it shorlty after purchasing it. Ignored it for a long time but have had to drive it more lately and feel unsafe doing so. The vehicle has not been inspected by anyone. It has less than 25,000 miles on itand the problem seems to be getting worse

While driving cross country, driver began to experience lag in acceleration and delayed shifting. In some cases, noted transmission was not down shifting. At destination, the check engine light came on and we took the vehicle into a Ford dealership for repair. It should be noted that there was a low coolant light just prior to the trip and we filled up approximately a quart to bring it back to serviceable limits. The dealer called after several hours to explain the car would need a new 2.3L EcoBoost engine and new Automatic transmission. The engine had evidence of coolant in the engine/oil. The transmission was diagnosed to have a failure of an internal component. The vehicle was been regularly serviced for the 79000 miles with no previous warning lights. We currently have the vehicle in our garage trying to decide if it's worth fixing for $25000 quoted by the dealer.

I noticed that I had to refill the coolant/water on my car because it was low. When I got out of my work I noticed there was water on the floor, but I didn't think of anything because my car was doing fine. When I was almost home I noticed the car fans were like trying to compensate for the heat, but when I look at my dash. My car was overheating with the engine light. I parked it and noticed the water I put this morning was all gone and the car was still leaking. Come to find out it was the water pump and the engine.

2017 Ford Explorer with 114,000 miles. Engine coolant light came on while driving. The car was taken to a Ford Dealer and diagnosed with a failed water pump. As the water pump is installed inside of the engine this is now a major repair and if not caught early, can cause permanent damage to the engine. This failure can cause the engine to stop leaving you stranded. Currently having the engine repaired at Ford Auto Nation in Tustin Ca.

Coolant was found to be infiltrating cylinders 2 & 3 of the engine. The engine was idling roughly and just about died before the check engine light came on. The service center did a pressure check and used a bore scope to confirm that there was coolant in the cylinders. My understanding of this problem is that the engine begins to misfire as coolant and oil mix and the cylinder walls start and other components deteriorate. When deterioration is bad enough the engine can quit. This can happen at any time including at high speeds on the highway. I'm not totally sure how long the rough idling had been going on, but the incident where the engine almost died and the check engine light came on was at about 80,000 miles. My guess is that the rough idling started around 70,000 miles -- give or take. Ford has not yet done a diagnostic teardown to determine how the coolant is infiltrating the cylinders, but it is a known problem for other sizes of the Ecoboost engine. I have the 2.3L Ecoboost. There was a recall on the 1.6L Ecoboost and there is a class action lawsuit for the 1.5L, 1.6L, and 2.0L versions of the engine.
