If we had not caught it soon enough we could have been looking at replacing the motor. Unfortunately for us this is a repair we have to make in a vehicle we are still making payments on and need for work.”
“The specific component or system has not fully failed. However, my vehicle is currently experiencing an intermittent check engine light condition, turning off and on, which was diagnosed at a Retailer producing code P0018 then at the dealership and produced code P0017. The codes relate to the engine control module (ECM) detects that the camshaft on is out of sync with the crankshaft resulting in misaligned engine timing. I have requested that the dealership further review and escalate the diagnosis to determine whether the issue aligns with any known concerns, Technical Service Bulletins, or manufacturer-supported programs. The vehicle and any related components are available for inspection upon request. At this time, the vehicle experiences reduced engine performance, including stalling, and inability to accelerator as needed, which pose a safety risk while driving, particularly in traffic or at highway speeds. The vehicle has been inspected and confirmed by the dealership. I have also contacted the manufacturer, who advised me to work directly with the dealership to have the issue reviewed and potentially escalated. I have since requested that they further…”

“The contact owns a 2015 Ford Explorer. The contact stated that upon placing the gear shifter in park(P) and turning off the vehicle, the message "Transmission Not in Park" was flashing on the instrument panel. The contact stated that the vehicle failed to start up after several attempts. The contact called an independent mechanic, and the vehicle was towed to the shop. The mechanic discovered that the water pump inside the engine was defective and needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 72,000.”
“When accelerating and braking, motor rocks forward and backwards. Rpms jump erratically when this happens and when sitting stationary at a light or stop sign. Which causes the entire vehicle to vibrate. Oddly enough, fuel injector cleaner seems to help with the vehicle shaking somewhat.”
“1. Component/System Failure: The water pump on my 2016 Ford Explorer failed, causing a significant antifreeze leak. The component is available for inspection upon request. 2. Safety Risk: The failure creates a risk of engine seizure while driving. Loss of engine coolant can cause the engine to overheat suddenly, potentially leading to a dangerous situation on the road that could harm myself or other drivers. 3. Confirmation of Problem: The problem has been confirmed by the dealer service department during inspection. The water pump leak was observed and diagnosed by a certified Ford service technician. 4. Inspections: The vehicle has been inspected by the dealer. I have also documented prior repairs to the vehicle, including a timing chain replacement two years ago. The water pump issue has not yet been inspected by Ford corporate. 5. Warning Lamps/Symptoms: Prior to the failure, there were no warning lamps on the dashboard. I noticed coolant leaking from the water pump area, and the temperature gauge began to rise. The leak was first observed AUG 15”
