This vehicle is using oil in a rate of about 7-8 quarts every 2000-2500 miles. When the oil dipstick is checked there is not a drop of oil on the dipstick. I have spoken with the dealership concerning this matter and the suggestion from FORD was to purchase another dipstick, which would cost my pocket book around $600. The dealership indicated that there is a service bulletin out at FORD addressing this very issue, however FORD Motor Company will not pay for the repair. There is no way a brand new vehicle should be using this much oil in that little of miles driven. I have searched the web and found hundred of vehicle owners who are describing the exact very nature that I am reporting. FORD's fix was to put thicker oil in the motor and change the oil dipstick. Can you please contact me in regards to my complaint about this issue.

I own a 2018 Ford F-150 with 56,000 miles, and I have been experiencing serious and unpredictable transmission issues. These problems first started around 48,000 miles, but at the time, I assumed it was normal behavior. However, the issues have progressively worsened, and by 55,000 miles, a wrench warning light started appearing intermittently. Symptoms: •While driving at highway speeds, the transmission unexpectedly drops from 10th gear to 1st gear, causing a sudden and severe deceleration. •The gear shifts are jerky, unpredictable, and rough, making it difficult to maintain control of the vehicle. •The wrench warning light appears occasionally but disappears quickly, making diagnosis difficult. •No diagnostic trouble codes (D DTCs) are stored or retrieved when scanned at multiple repair shops. •The issue happens intermittently, making it challenging to replicate on demand. •Started noticing issues at 48k miles, but they became significantly worse around 50k miles when the wrench light began appearing. •I called Ford to reset the radio/computer software, after hearing it might help, but it did not resolve the issue. •The unpredictable transmission behavior causes severe anxiety while driving, as I never know when it will happen again. Attempts to Fix: •I have taken my truck to multiple repair shops and Ford dealerships, but since no codes are present, they have been unable to diagnose or fix the issue. •Mechanics have checked for transmission recalls or software updates, but no clear solution has been provided. •I contacted Ford for a radio/computer software reset, hoping it might help, but this did not fix the problem. Safety Concerns: •The abrupt downshifting poses a serious safety hazard to myself and other drivers on the road, especially at high speeds. •There is an increased risk of accidents due to sudden deceleration and loss of control. •The problem occurs without warning, making it difficult to predict or prevent.

This truck was supposed to be recalled under the Transmission recall for 10r80 and I noticed while conducting a decode on the vin number that the type and kind of transmission was never listed so I’m wondering how many people have been going through the same issues as us and if this will get fixed because our vin is not recalled and it should be

With 83,000 miles, we checked the oil to discover it was empty. Upon taking it to the dealer, they determined that there was severe scoring due to the known PCV value issue under TSB 19-2365 for excessive oil consumption. Prior to this time, there had been no oil issues with the vehicle. Dealer recommended replacement of the engine. The engine was replaced in August 2024 with a remanufactured engine. The oil was changed on December 5, 2024. From that point to February 25, 2025, the oil was checked periodically with 3 quarts of oil being added over that period of time. We took the truck back to the dealer to check to see why there is excessive oil consumption again. The dealer instructed us that they would need to follow the recommended action in TSB 19-2365 to reprogram the powertrain control module, install a new engine oil level indicator, and change the engine oil. We would then need to bring the truck in weekly for the dealer to check the oil to assess whether there was excessive consumption of oil. We asked why the engine would have been replaced in August 2024 with another engine that had the same problem as the engine replaced. Weren't the corrections done to the engine per the TSB 19-2365? We were told they did not know.

A significant knocking sound can be heard from my truck during cold start and when at idle and remains an issue that Ford did not address as part of their Customer Satisfaction Program 21N03 issued on March 21, 2021. That specific CSP specifically excluded my model (Ford F-150 Raptor) from the program; however, my vehicle exhibits the exact same cam phaser issues and has already been identified by my local Ford dealership as the root cause. I am submitting this request that the federal safety agency will require/force Ford to honor their product and fully cover the cost of needed repairs no different than what they did as part of the CSP 21N03.
There was something wrong with the Ford 10 speed transmission on my truck - 2018 Ford F 150. The transmission would jerk hard at completely random times. The biggest safety issue was that at times it wouldn't "go" when you pushed on the gas causing a delay that was particularly problematic when you were pulling into traffic. There needs to be a recall. If you google F150 10 speed transmission problems, there have been a myriad of them.

Powertrain control module software is faulty, causing improper diagnosis of catalytic converters efficiency. Prompting a check engine light and P0430/P0420 code. I could not pass emissions testing with this code. The Ford dealer made me pay out of pocket to replace catalytic converters ~6 months ago, total cost of $2975.12. The have now addressed that it is unlikely the catalytic converters were faulty, and are offering no reimbursement.

My coolant/water housing had an issue and caused a leak by the thermostat and it caused my engine to overheat while I was driving. I had my 10yr old son in the vehicle with me and had I not had the opportunity to pull over into a Walmart parking lot almost immediately in order to get some coolant into my truck, it would have been disastrous. The warning for high engine temperature was the only warning I had as I was unaware that I had any type of coolant leak. This could and may have caused some more damage than just the mandatory repairs that I had to do because this is my mode of transportation to/from work for the Federal Government.

Ford F-150 equipped with 5.0L with 68,000 miles has a significant amount of engine oil loss between recommended intervals from the manufacturer. Took vehicle to dealership it was bought from brand new, they confirmed the level. Added oil, then the service department manager said, “we’ll have to do the oil consumption test. This is the test Ford recommends on the Service Board and they know about the problem.” They will send data to Ford, and Ford will recommend to “more than likely put a new motor in.” Since I’m just out of warranty, I have to pay over $15,000 out of pocket for a problem Ford knows about.
