2019 Ford Ranger: check engine light

Filed Jul 1, 2026 · Electrical, Engine · CA

I was driving the vehicle, when I started to fell a " Shuddering " sensation on acceleration. I let off the gas pedal and the Shuddering went away. A few miles down the road the check engine light came on and was flashing. I immediately pulled and shut the vehicle off. After sitting for 10 minutes I restarted the vehicle and the check engine light was no longer on, but the " Shuddering " sensation was still present. I took it to Dupratt Ford in Auburn,Ca. and they diagnosed it as a Cylinder 1 mis-fire. Upon further inspection they found water in the Cylinder 1 spark plug well. After doing some research I found out the Ford issued TSB 23-2011for this exact issue, but did not order a recall to fix the faulty windshield cowl which is the problem. I found thousands of complaints and numerous Ranger owners who have had the exact same issue and had to pay out of pocket to get the issue and damaged fixed. Meanwhile Ford knew about the issue and did absolutely nothing, did not even alert the owners of the issue. I was lucky and did not have to replace the cylinder head, but others have not been so lucky. I had to pay over $1800 to have the mis-fire issue fixed and had to do my own preventative measures to seal the windshield cowl. I contacted Ford and they were only willing to reimburse me $725 dollars of my repair bill which was 100% their fault.

On friday, march 27th, 2026. My 2019 ford ranger began shaking before the engine stalled. Warning lights for an engine check came on and my vehicle would not go above 20 mph after restarting. When pressing on the accelerator the engine would rev but the vehicle would not accelerate. I took the 2019 ford Ranger to a local Ford Dealership service center and they diagnosed the following problems (listed in full below).The cooling fan was at issue and multiple wires connecting my engine to the rest of the vehicle were melted off. The ford dealership said that this issue is extremely rare and they have never seen it before. After receiving this information from the dealership I discovered that the 2019 ford ranger has had several recalls with the areas at issue in my vehicle. The recalls are under number 25V685000 (Engine block heater), and 20V137000 (Fan). Here is the full diagnosis from the ford dealership attached below: VERIFIED CUSTOMER CONCERN FOUND VEHICLE TO HAVE CEL LIGHT ON, AND MULTIPLE WARNING LIGHTS PERFORMED DIAG AND FOUND SHORT CIRCUIT PRESENT. TRACED SHORT FOUND COOLING FAN CLUTCH FAILED AND HARNESS RUBBING IN CLUCH ASSEMBLY FOR COOLING FAN The fan lowers the temperature of the engine. The cooling fan motor is an electric motor that turns the fan blades. When the vehicle is in traffic or under heavy load, the engine relies on the fan to cool itself. Some vehicles may use multiple electric fans for better control of the cooling system. For the most part, electric cooling fans are controlled by the same computer that controls the engine. However, in some engines, the fans are turned on and off by a temperature-sensitive switch mounted in either the radiator or elsewhere in the cooling system. Spark Plug Replacement 4 Cylinder: 4 Cyl Tune Up The platinum spark plug is a type of spark plug. The platinum is a precious metal that is used in the composition of the spark plug.

The check engine light illuminated after leaving residence and traveling less than 5 miles. Had the vehicle check by a certified ASE mechanic, He stated that my vehicle had a misfire code (PO300), if it was a PO301 OR PO302 or etc, it would indicate a specific coil was misfiring, but the PO300 is a general misfire code. Vehicle is jerking, pulling, bogging down as if doesn't want to go forward or is losing power, mechanic changed the spark pulls the first time thinking it was time due to mileage of the vehicle, and cleared the code. One week later check engine light is back on with the same PO300 code, he says we can try changing the coils next to see if this fixes the problem. I called my local ford dealer, who says the will charge me $167 dollars to diagnose the problem, and tell me whats wrong. After I have already told them what the problem is and what the code is for the problem. Which is the same code i got from my $40 code reader is the same code he got from his $1500 code reader, so what can the tell me for $ 167 that i dont already know and have told them, and from further research on recalls for this vehicle, I have found that they already know this problem exist. Ford should be responsible for repairing this know issue of engine misfires before someone dies from this engine shutting down while driving and causing a fatality on the highway.

2019 Ford Rangers were shipped without an engine cover to protect the engine from water intrusion. Â This, along with the design of the plastic cowl at the base of the windshield being a 2 piece design with a seam directly over the engine bay, allows water to drain into the engine bay during periods of heavy rain. Water will drain from the windshield into the top of the engine, and begin filling the spark plug wells under the ignition coil boots and into the engine head. Â This water intrusion can cause engine misfire codes as well as a loss of power while driving, and on multiple instances while merging into traffic, the engine would bog down. Â It wasn't until the most recent occurrence that a check engine light came on. Â I immediately pulled into a shop and they found the plug wells were rusted, corroded and full of water from this happening since the day it rolled off the lot in 2019. Â I have had an independent mechanic assess the damage as well as had the vehicle towed to a local Ford dealer and they found the same condition- with the only solution to replace the engine head as they are unable to remove the plugs due to the damage caused by the water intrusion. An owner should not have to be concerned with parking or driving a vehicle in the rain and whether it will suddenly lose power while driving at highway speeds. Â This is a safety issue that Ford should be forced to take care of. Â They are aware of the issue and have been as they have issued multiple service bulletins with a solution for misfires to change plugs and install an engine cover. Â An engine cover has no bearing on an engine misfire but it shows Ford knows water is getting into engines and causing these problems. Engine/plugs/coils failed, it is available for inspection. Mine and public safety was at risk when driving as it lost power merging into traffic. Â Problem has been confirmed by dealer and independent mechanic. Â Last instance (2/9/24) was first time a CEL came on while driving
