2010 Ford Flex: check engine light

Filed Mar 19, 2023 · Engine · ID

While driving at 65mph, vehicle started to accelerate funny and cel came on. was getting on the freeway and the vehicle overheated and CEL light came on. I was able to safely pull over before the vehicle died. Got vehicle towed to my home and when engine oil was checked, it was discovered that there was coolant in the oil. Took to a local shop where it was determined that the water pump had failed and dumped all of the coolant into the oil pan. Estimated cost of repair with labor is $5,000. Failure mileage was ~192,000. The oil was in good standing and gold in color 12 hours prior and was only driven ~45 miles at highway speeds before the failure happened. From what I can tell, this was a catastrophic failure of the water pump bearing seal that happened almost instantaneously. This needs to be looked into, as the repair bill does not match the issue. A water pump repair should not cost more than the vehicle.

The engine shut down during a long-distance drive returning from a vacation. The car was towed to a ford dealership. The techs at the dealership determined that the engine failed due to a faulty (leaking) water pump. This water pump is inside the engine block. Thus, the leak caused corruption of other parts of the engine and complete engine failure. This problem with the internal water pump has been the subject of a recall for other ford models, but not the ford flex. The national database of automotive technicians, identifix, reports leaking internal water pumps to be the number 1 problem with the flex. Here are the specifics of what happened: we had been driving for approximately 6 hours. I was at cruising speed of 75 MPH. As I approached lubbock tx, the temperature warning light came on and the temperature gauge had pegged all the way to 'hot'. I reduced speed and drove to the next exit (approximately 1-2 min away). As I exited the freeway, the engine light came on, and moments later the battery light came on. At that point, I lost power steering and the engine shut down. We were able to push the car into a parking lot on the frontage road. This incident is consistent with the claims that have LED to the safety recall for other ford models:escape suvs from the 2014 model year, plus the 2014 and 2015 compact fiesta st, the 2013 and 2014 fusion midsize car and the 2013 through 2015 transit connect small van (obtained from USA today, 1/3/2018). My insurance will not cover the damage which has resulted in the car being "totalled". This is a known problem for ford, and I believe my car should be covered under the recently announced safety recall. This problem in the ford flex has been discussed for years dating back to at least 2008 (https://www.fordflex.net/forums/viewtopic.php?t=17392)

While merging onto a highway the engine suddenly lost power and began shuttering/vibrating badly. This loss of power nearly caused a severe accident as the sudden slow down caused cars behind us to take evasive action. The check engine light illuminated immediately. We drove the car to the dealership per instructions from the service rep. The vehicle has the 3.5l ecoboost engine. The service tech first said an ignition coil went bad and replaced it, only to discover that it did not fix the problem. They did a cylinder compression test and were loosing compression in one cylinder. The engine had to be disassembled to diagnose the problem. The service tech found the cylinder rings had failed in one cylinder and now has to replace the whole engine at a cost of $7,800. The engine only has 55,000 miles on it! There were no warning indicators that anything was wrong with the engine, and it has been routinely serviced. Ford is unwilling to help in any way with the repairs as the vehicle is out of warranty.
