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.

Ford has done a service bulletin on the cam phasers once before. The issues are still not fixed and all they say is it's normal. An engine rattling due to a part they installed is not considered normal. Wrong parts were used and the problem still persists. Ford needs to be made to recall 2015 to 2019 f150 trucks as well as any other series that have the issue. The service bulletin only gave people a certain amount of time to come in and have it fixed the first time which left a lot of people out of luck due to lack of communication to the owners of said vehicles.

12/26/2023 Re: VIN: Case#:[XXX] 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

Transmission jerks, and stalls. Drive train noise. Engine cuts out and has rough idle.

- Cape Girardeau , MO, USA

The vehicle has given codes P0018 and P0021 on multiple occasions. These codes are likely due to an issue with the cam phasers. This is a known issue due to a design flaw.

- Sharpsburg, GA, USA

I drive a 2019 Ford F-150 XLT 4WD (8 Cylinders 5 5.0L FI FFV DOHC 302 CID). During November 2023, I was experiencing the truck bucking and jerking and shutting off at red lights and stop signs. I took my truck to the dealership on November 22 to have them look at it. They replaced the starter, an almost dead battery, and a PDM reset. The PDM reset and starter were covered under my extended warranty. Upon driving my truck home, the problem continued to exist and this time much worse. I returned to the same dealership on Friday, November 24, 2023. After a diagnostic test, they found nothing, then stated a couple of people drove the vehicle and could not duplicate the problem I was complaining about which was stressful and frustrating because this problem exists almost every time I drive the vehicle, regardless of how long my trip. Driving this truck has now become a safety hazard as I almost got struck by other vehicles on more than one occasion. When I pull out from a traffic light or any business establishment, I have to keep tapping the gas peddle to get the truck moving and it doesn't move, leaving me stranded in the intersection. When the truck does move, it jerks so hard that it gives you "whiplash". This jerking motion continues during the duration of my trip, including my hour-long drive both to and from work. I took my Ford to another mechanic on December 19, 2023. The establishment sent one of their technicians to ride along with me to experience the problem for himself. I drove out of the driveway for just a few feet when again, I kept tapping the gas pedal to get the truck to move and when it did, the truck jerked violently. The technician saw what he wanted to see. I get no warning lights or messages about the failure. The technician said it was a transmission problem that he has been seeing with the years of 2017-2019 F-150 and Ford is aware of the problem but does nothing about it.

Approximately 2 weeks after purchasing the truck I noticed some harsh shifting, jerking, and sudden acceleration, and hesitation issues. They were intermittent and I was advised this is not uncommon with this model vehicle. However, these issues have become more frequent and severe. Next, I noticed the gears began slipping and the truck seemed to not be able to -??find-?? the gear it needed to be in. The transmission would slam into gear or begin slipping under acceleration. There is no rhyme or reason to it, I have not been able to pinpoint it to a specific gear or up/down shift. It simply loses power and neither the gas nor brake work. It will coast until the wrench (check engine?) symbol comes on and then the gas will function. This week the transmission has started intermittently locking into a specific gear without the ability to shift. It-??s now happened 3 times. You cannot reverse or drive, the transmission puts itself in park while the dash still indicates its in drive or reverse. After parking the truck for a couple of hours, I could start and drive as usual. Most importantly, twice Saturday the truck seemed to shift out of gear, so hard my head hit the steering wheel, and lost power going 70mph on I64. I have attempted to video these events to help diagnose the issues, but obviously driving and recording are dangerous and difficult.

- Drift, KY, USA

Truck uses an excessive amount of oil that would not be corrected by Ford. Due to this issue the truck failed to operate normally. It stalled in the middle of an incredibly busy intersection, causing traffic back up as well as increase safety concern for the drive of the truck as well as other drivers on the road. This has happened multiple times. Ford is aware of the engine oil consumption issue. Has expressed multiple times that it was not a problem. Attempted to fix by selling a new longer dip stick to attempt to hide the problem with excessive oil consumption.

Vehicle engine, cooling, and exhaust. Cam Phasers noise when starting

- Prosper, TX, USA

My engine light came on and within the same day my vehicle shifted extremely slow. it was difficult to merge into traffic and almost caused an accident. I took the vehicle to Mechanic and they advised the engine light was consistent with the timing chain failure. I called a local local Ford dealer. They seem to be familiar with the issue and said it would cost $4000 to fix.
