Filed Jun 30, 2026 · Fuel system, Transmission · MA

While driving at a low speed, when pressing the accelerator, the auto initially didn't respond, but then accelerated sharply after a delay (when the accelerator wasn't engaged). The transmission seemed to abrubtly shift up by 2 or 3 gears without warning requiring me to immediately depress the brake to avoid hitting the vehicle in front of me.

Truck is stalling at low speeds or idle when in drive or reverse causing me to get stranded in turns or at stop lights. No check engine lights have come on and the dealership said to wait but it’s happening constantly. Occasionally the auto start stop will say it’s failed but the stalling occurs when it’s enabled and disabled

My F150 constantly needs oil and seems to lag when the oil tank is low. 163000km on the engine. I've heard other 2019 f150 drivers have the same problem. It also has a hard shift after sitting for the night, it will drop gears while going uphill which seems to be from third gear to fourth but instead drops to 3rd again creating a clunk noise. It hasn't caused an accident or anything yet but from my last truck this thing definitely was not built the way it should have been. I think Ford needs to have a serious look at these trucks before someone gets hurt.

I drive a 2019 Ford F-150 with the 3.5L engine and 10 speed transmission. I have received a warning for low fuel pressure, trouble starting, and the truck has cut off once after turning over. It never fails to crank, however, it may take 5 or so seconds of cranking to get it to start. I have had the check engine light come on one time over the last couple of months of the issues starting; the code it showed was a P00C6. I have not brought the vehicle in for service as it just started a couple months ago when it got hot outside and there was a recent recall that did not include this VIN but matches the issue exactly. The warning states to not drive the vehicle and to get it towed if fuel is not low. The recall states there is not a current fix for the issue and I need my vehicle. This is a daily problem, mostly after the vehicle sits for a couple of hours. I am also having an issue with the cam phaser rattle upon startup and rattling while driving. I have noticed some power reduction and it has progressively gotten worse over time. I am at 135,000 miles currently and have experienced this issue for the last 50,000 miles or so.

Had oil change 7 times in one year and each time they indicate at the place I get oil changed that it is a quart or more low before 3,000 miles of usage after oil change. My car is suppose to take unleaded gas or higher and it knocks if I use unloaded. Now my catalytic converter is going out and it is not covered under warranty unless it is consequential to other problems. Well there appears to be engine problems that are not being addressed and I have a warranty and have taken it in. But they do not look any deeper into the problem except for computer scan and the warranty people won’t give me any answers on what they will do if there is engine problems.

The metal fuel line from the canister up to the high press fuel rail developed a crack and ruptured without warning. The vehicle was unsafe to drive because it poured a significant amount of gasoline onto the ground when the fuel pump came on. The vehicle was towed to the dealer for repair. The fuel line was inspected by the dealer's technician, rupture was confirmed and both fuel supply and return lines were replaced. After repair was performed, the dealer service representative showed me the fuel line that was replaced.

The Ford F-150 cam phaser issue primarily affects models from 2011 to 2020 with the 3.5L EcoBoost and 5.0L V8 engines. The cam phasers, which are components in the engine's variable valve timing system, are designed to adjust the timing of the camshafts to optimize engine performance and efficiency. The problem arises when the cam phasers start to fail or become noisy, often producing a rattling or ticking sound, particularly on cold starts. This noise is due to the phasers not locking properly or wearing out prematurely, leading to improper timing adjustments. Over time, this can result in reduced engine performance, poor fuel economy, and in some cases, engine damage if not addressed. Ford has issued Technical Service Bulletins (TSBs) and extended warranties for some vehicles to address this issue. In many cases, repairs involve replacing the cam phasers, timing chains, and associated components, which can be costly. The issue has led to customer dissatisfaction and several complaints, with some owners reporting multiple repairs before the problem is fully resolved. I was not sent the letter advising me of the customer satisfaction solution and now Ford wants me to pay $4,000 to resolve this issue.
