The variable camshaft timing (VCT) solenoid becomes gummed up, causing the engine to lag. Specifically after driving on the interstate or highway and then sitting at a red light. The VCT does not perform properly and the engine idle drops, causing the truck to stall and die at the light. Online forums show this to be a common problem for the past couple generations of this Ford 5.0 L motor and always seems to occur between 80,000 and 100,000 miles.

12/26/2023 Re: VIN: Case#:46906606-D1R6H6 I purchased this truck new 4/1/2019 and purchased a Ford Extended warranty(Ford Protect) the following month for 5 years/125K miles. This was my second F150 with the 3.5 ecoboost engine. Since that time it has been serviced continuously by Ford Dealerships. At no time during that time period under warranty has any Ford dealership mentioned that there were service bulletins out to the dealerships with regard to failing Cam phasers. From research that I have done over the weekend there is apparently a New type phaser being used on F150-??s since 2021 that corrects the problem. If Ford and all of the Ford dealerships knew of this common problem why were not the Ford customers notified of the issue? I went in for an oil change last week and the technician noted a tiny sound when the engine started. I went back the following week to have a sensor replaced and the mechanics indicated that there was a camshaft/phaser problem that would cost $4200 to fix. That issue could have been fixed at any time under the extended warranty from 2021-2022 if the dealerships had notified the Ford customer by using the same phasers installed on new trucks. I received a follow up call from a Ford rep 12/28/2023 who denied that I had a Ford Protect extended warranty. I verified the policy 12/29/2023 and called Ford again who again stated that I did not have a Ford Protect Policy. Finally it took a conference call with the dealer to convince Ford who still would not agree to fix the issue. The Dealer offered to extend the policy until realizing that it had been diagnosed with a cam phaser failure stating they could not warrant an existing issue. That is exactly what the dealer did in 2019 when they sold the extended warranty on a known issue. Phasers are the critical feature that controls the timing and computer controlled oxygen input and exhaust for ecoboost engines. When they start to break down it affects the health of the engine itself.

Drivers side wiper arm is visibly loose. It does not make constant contact with the windshield Engine consumes 3 quarts of oil in less then 2k miles, it currently has 57,818 on odometer, has been regularly serviced Ford recommend 91 or above octane to curve -??pinging and pre detonation-??. Have run 91 octane fuel for last 5 tanks and continues to misfire and ping between 1500-2000 rpms while under no load besides the weight of the vehicle

I got the truck with 10,00 miles and currently have 47,000 miles. I have been having oil burning issues since the beginning, but it has gotten worse. When I was adding the oil myself before having the dealership do it I was having to add almost 4 qts per 5-6 thousand miles. I have been taking it to the dealership every 1000 miles for oil consumption test. Typically, my oil burns over 1/2 qt per 1000 miles so the dealership claims. I have also claimed about harsh shifting and clunking noises. Most recently I took it in for the harsh shifting of the transmission and 4 wheel drive while the did the oil test. They reflashed the transmission and topped off the oil. The dealership then forgot to put the oil cap back on (I didn't think I had to check their work) the next day after a short drive there was oil all over my engine, electrical systems, battery, suspension and underbody because of the missing cap. They took the truck back and then claimed only a 1/2 qt was gone. The dealership after a few days tells me it is all cleaned and ready to go. I got the truck with oil all over the place. So they keep the truck yet again, few days later I get the truck back and my truck is shifting worse in some ways now than before the flash. Today I had to take the truck in for an engine light about the catalytic converter failing. While they had the truck there it then gave a bunch of codes of powertrain body control all related to lack of power and powertrain failure. displaying a bunch of red lights including a gear wrench on the instrument cluster. These only appeared after the tech scan the first code. The dealership now has my truck yet again and have said it will be at least a few days.

My truck rough idles and shakes violently and then stalls and an error comes up in the dash telling me -€œauto startstop shift to P then restart engine-€ Has happened numerous times. Truck currently has 44, xxx miles. This is extremely dangerous at any light, turning intersection, or stop sign. I have read many online threads through online forums of this happening in other f150s to no avail from owners and dealers alike.

Recent oil analysis(mid October 2021) indicates a greater than 5% fuel dilution. The Cummins ASTM method of testing only permits a greater than 5% statement so fuel dilution could be much higher. First sample a year ago indicated 3% dilution. Many factors could contribute to this per research and I had advised Ford dealer with printed reports and they would not do anything at all about this stating it is standard. Oil report indicates a "severe" issue. Ford dealer wouldn't even look into possible causes to rule out. I have concern for a possible engine compartment fire/explosion might happen or possible degradation of engine leading to other possible incidents. Reports and vehicle are available. No indicator lamps or other means to know of this issue without independent testing of oil samples. Fuel mileage is averaging 17MPG.

Our brand new 2019 Ford F150 was having shifting problems. Very rough shift from 5 to 6th etc. Clunky. Called dealer. Was told it would "even out" driving from tx to ga it only got worse. Dealership in ga says it was shipped low of transmission fluid. It is a closed system, so they said it had to be shipped from the factory low. We drove 5500 miles with a transmission that was 2 qts low and got no errors, lights or notifications. We picked up the truck on Oct 10, 2020. It still felt very clunky, so we tried in November and early December to have it looked at again. They could not get a loaner etc. It was not serviced a second time at this point. On Dec 24th around, we were driving down I 20 going roughly 70mph. Thankfully, my husband was driving. The truck began to feel rougher on shifting ( it is an automatic) suddenly, the truck lunges like we pulled the emergency brake and it shifted from 10th gear to first, he knew to put into neutral and get off the highway. We immediately pulled to the nearest exit and drove home about 4 miles very slowly. Because it would jerk very hard if it got to 5th gear and tried to go to 6. after several days due to the holiday, the truck was towed to Ford who now say it is too full on transmission fluid and they cannot duplicate the problem. We would have crashed if I were driving. The sudden stop and sudden gear change only magnified the problems we were having already with the truck. There are numerous reports of similar issues across the country. Ford needs to do a recall before someone dies.

Noticed during summer 2020 months the truck when idling at stop would vibrate and tachometer would bounce. Recently during July to September the truck when stopped would idle rough then shut down completely having to put in park and restart the truck! the last time it did it I was sitting at a red light on a city street and it just shut down and I had to restart the truck. This has happened 4 times since July. I took it to two Ford dealers and neither could replicate the problem and told me they could not fix it.
