When I accelerate after a stop my truck starts jerking when shifting thru lower gears and the check engine light flashes. To increase my speed I have to slowly press the gas until it shifts thru gears. After it shifts thru the lower gears it appears to be okay. It doesn't do it at each stop but is now happening more frequently. I don't know if it's a transmission problem or fuel pump. Current mileage is around 62000. If I'm on the highway it will sometimes start jerking while the using cruise control and I have hit the brakes and take over acceleration. I've now parked the truck because dealer cannot get to it for 3-4 weeks.

The contact owns a 2019 Ford Ranger. The contact stated while driving approximately 10-15 MPH into the driveway at the residence, the vehicle lost electrical power and the vehicle shutoff as if there was no fuel going to the engine. The contact stated that there also a message that the rearview camera was inoperable, along with messages that features inside the cabin of the vehicle was inoperable. The contact restarted the vehicle and the vehicle shutoff immediately. The contact stated that the engine was not receiving fuel because the fuel pump was on the wiring harness that was not operating as needed.

This is in relation to an existing recall on the 2019 Ford Ranger, the federal safety agency Recall no. 19V‑839 This recall was for improperly connected inline electrical connectors from the Ford factory causing issues with rear brake lamps. I have recently had a fault with the same connector, which Ford technicians discovered was not properly connected. This connector failed due to the loose connection, causing all electrical connections in the rear frame (fuel pump, rear view camera, cross traffic warning, parking sensors) to fail. Upon discovering recall 19V‑839, I contacted Ford support. I was informed that my truck was built in the same factory as the recalled vehicles, but was completed three days after the impacted period ( JUN 04, 2018 - AUG 16, 2019). Therefor Ford will not consider my issue part of the recall. Ford has advised me to bring this up to the federal safety agency to broaden the scope of the recall. I It seems clear to me that this issue was the same as the recall, and likely the original dates were too narrow. I hope you will investigate this issue.

We love Ford Rangers. This is my 4th. It has been wonderful, until [XXX]. We had to replace an A/C, but that's normal. We've also noticed a very few times that when the transmission shifted, there was a little jolt. But that was rare. But on [XXX], after stopping at a light at the intersection of [XXX] and [XXX] in Indianola, MS., we had a frightening experience. After crossing the busy highway I began to accelerate and suddenly the truck jolted forward and quickly accelerated to 70 mph. I hit the brakes, and after a couple of taps it slowed down. But when I gave it more gas, it only roared twice, and no power...with big trucks beside and behind me. That was frightening. Then it returned to normal, and I went on to Isola, MS. Upon leaving it didn't want to move forward, only roaring, but then quickly responded and was back to normal. I was scheduled for a 12:30 lunch meeting in Leland, MS and my wife and I proceeded. All normal. Upon leaving Leland, same thing. No power at first, then it moved forward, normally. We noticed it was a rough shift at 45 mph as we got out on freeway. I called the service department at Hallmark Ford, Batesville, and told mgr. my problem. Thought it might be fuel pump, filter, or transmission. Upon arrival at home, it wouldn't go in reverse. I sent it to dealer on wrecker. Got second opinion. Both say it needs a new transmission at $8900. My concern is will the new transmission have same problems...reading now on internet of other people who have had similar events. Money matters, but MY CONCERN is the danger this could have inflicted upon us. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Problem with fuel pump city switch keeps burning up and causing my truck to to die while I’m driving it. I have got it checked by a mechanic shop and the problem keeps happening. The fuel pump, the cut off switch and the connector and wires have all been replaced and it still continues to happen. This has been happening for years and is causing me to almost get in a car accident.

I would be driving and all of a sudden the whole vehicle would just shut down. This happened 3 or 4 times just going at 25 to 35 MPH. At first, I thought it was a clogged fuel line since it would somehow reset itself after having it towed to my mechanic so I replaced the filter even though I could see nothing wrong. When it happened again on a backcountry road the mechanic said it was probably the fuel pump so I had the whole thing replaced. It happened one more time after that, I was pulling onto a major highway and had just gotten up to speed 55 MPH and there was a tractor-trailer behind me when all of a sudden again everything shut down. Luckily I had enough moment built up I was able to coast to the side of the road before getting hit by the tractor-trailer. I finally looked online and found that someone had mentioned the same problem it may be the inertia switch. I called up a local dealership and had asked the parts person if the had a replacement and if he heard any problems about it. I was told it would have to be ordered because they were out of them, they had sold a few in the past months. When I explained the problem I was told oh yes we have heard about that happening but there was no recall. I explained how it could be a safety problem and was told that it must not be happening enough for it to be a recall. I recently found this site and have seen that I am not the only one who had this happen so at least I know I wasn't crazy.

Extreme fuel dilution in the oil. Likely from leaking high pressure fuel pump. I have attached the results from oil analysis at 1860 miles. The test only indicates that fuel dilution is above 5%, which itself leads to severe oil degradation. When I changed the oil, I drained 7.5 quarts out of an engine with a 6.2 quart capacity. This would indicate a 21% fuel dilution, not including fuel that has evaporated from the crankcase and returned to the combustion chamber via the pcv system. If I abided by the manual's recommended oil change interval, I have little doubt the engine would eventually catch fire, based on the results of several tests comparing fuel dilution to an oil's flashpoint. After changing the oil, it smelled fine for the first 20 miles or so. After that, the oil began to feel of gasoline again. After going through ford's service manuals, I have ascertained that the problem must lie in the high pressure fuel pump. It runs off the camshaft, where leaking fuel could then make it into the engine and mix with oil. There would be no warning or indication, besides rising oil levels accompanied by the smell of gasoline in the oil. It does not make me happy that my dealer is not taking this issue seriously, especially because a fuel leak of any kind always has the potential to lead to a fire or explosion in the hot engine bay. I paid over $40k for this truck, and should not have to change the oil every 500 miles to keep it from self destructing. Thank you for your help in the resolution of this issue. I don't feel safe driving my family in this vehicle, and ford has repeatedly chosen not to address the issue. I first detected the issue on october 20th, but I have no doubt that it has been going on since the truck rolled off the assembly line. I purchased the vehicle on august 30th of this year.

Inertial fuel pump shut off switch kept shutting down vehicle... It happened twice in traffic that I was lucky enough to have enough momentum to coast out of harms way. Last time it occurred was parked and wouldn't reset, so I eliminated it and wired direct without the switch. No problem since. No other vehicle has switch like this that I'm aware of. I eliminated it!!!

Engine stalled ostensibly for lack of fuel. First engine stall episode occurred while vehicle was turning leftward into driveway at about 2 MPH and at approx 5 degree angle of inclination. Vehicle was towed from where it came to rest to repair shop where diagnosis was fuel pump failure resulting in replacement of the fuel pump (ford oem part.) vehicle performed reliably thereafter for a period of approx 39 months without stalling. Second episode occurred after vehicle shut off and resting on flat driveway surface overnight. The following morning engine cranked but would not fire or start. Again towed to different repair shop where diagnosis was again fuel pump failure however upon attempt to restart following pump replacement, engine would not fire or start. Troubleshooting revealed fuel inertia switch required reset after which engine started, system tested ok and vehicle performed seemingly properly for next 10 days. Most recent (3rd) stalling episode occurred at traffic control light in heavy traffic immediately upon acceleration from full stop on level surface and attempting to travel directly forward with no turn of the wheel. Following removal from roadway, engine could not be restarted until after fuel inertia switch was reset. Vehicle then ran under its own power additional 2 miles to home where it remains pending further troubleshooting and repair.
