2015 Ford Fusion acceleration problems

Filed Jul 12, 2024 · Acceleration, Brakes · MS

My first problem is that when i try to accelerate the speed it acts as if it doesn’t want to go above the speed that I’m already going! Also my engine light pops on and off and says it could be a number of things such as my brakes and exhaust. The last problem is that my brake lights will not turn off at all.

My car has been losing power and randomly stalling for a while now. Today as I was driving it was happening more and then suddenly my brake pedal became hard as a rock, and the hill assist warning came up. It keeps stalling and will not remain running for longer than 2-3 minutes of being on. This almost caused me to ram several cars due to not being able to stop quickly enough. No lights came on other than check engine and it has not been inspected as this has only happened today. However the stalling of the car has been going on for about 3 months and I’ve been very pregnant and unable to have it looked at. The loss of power in the car happens and sometimes downshift’s extremely hard causing a loud jerk noise from the underside of the vehicle. Once turned off and turned back on it goes right back to normal until it decides to do it again. It can happen a couple of times or it can happen 100 times within a 5 mile period and I never know when it’s going to happen until it’s actually doing it. Extremely dangerous and I’ve seen several 2015 owners posting about issues of the 2015 brake system/bumper etc. I’ve seen recall talk but this site shows no recalls, please get this issue recalled asap!

As I was driving, it felt as if my car had turned off or had no fuel, but no engine lights came on and i had fuel in my tank. Also all my electrical stuff stayed on, only lost power on the accelerator. My safety and others safety was put at risk because there were no warning signs i just had no "Go power" and no one around me knew my car had no power which could lead to an accident, serious injury or death; if on highway traveling at high speeds and it randomly dies. I took my car to a mechanic and they stated everything was perfectly fine they did a full diagnostic and the computer didn't show any errors in operation. This happened 3 times in one day at random times, i could put the car in park and re-start and it ran fine. however i did have to hold the key forward longer for the engine to turn over.

The throttle body failed. Car went into limp mode. I used a code reader to investigate. Code was P211, throttle. Bought a throttle body at Ford dealer, $100.84 total parts with tax and throttle body and gasket. Replaced part and it runs fine so far. I was lucky to have been close to home when it happened. I did not find any recalls for this make model and year but throttle bodies commonly fail on Fords. It happened on July 31, 2021. Car had about 89,500 miles. Bought the car new from Bill Utter Ford in Denton, Texas in 2015.

Traveling on highway at 70 MPH with sudden immediate inability to maintain speed (loss of power/acceleration). Vehicle not responsive to acceleration request until below 45 MPH and behaves erratically (just stops responding and car slows). No check engine light and car otherwise runs normally. Accompanying behaviors: brake lights are constantly illuminated (stuck on), even when not braking and also when car is turned off and key removed. Intermittently when car is stopped, message "hill start assist not available" is shown. Took car into ford dealership who diagnosed the problem and "found brake switch engagement bushing missing from brake pedal" and offered to replace the "brake pedal assembly" at a cost of $1,062.35. Found several forums complaining of the same exact behaviors and noting that the oem "brake pedal stop pad" had broken into pieces. I also remembered vacuuming up some plastic pieces from the driver front floor area not realizing where they had come from. The "brake pedal stop pad" itself which would cost less than $5.00 is not offered by ford, so people are finding alternatives which may be unsafe and include: "brake pedal stop pad" not designed specifically for this vehicle, zip ties, and even magnets! Other ford models are affected as well. Some example forum links below. This should be a recall.

While driving this vehicle the engine misfires decrease in power and completely stops acceleration. It also uses a great deal of fuel. The coolant constantly leaks out and the engine overheats every few minutes. The car also overheats when sitting in a parked position. While driving on the freeway the car slowed to 25mph. We were very close to being involved in an accident.

2015 ford fusion- after sitting for short periods of time the vehicle will not turn on until multiple attempts. The battery is good. No jump is required. Vehicle will go from no power on the first attempted start to managing to power on within a couple of minutes. While in drive, the vehicle will not switch gears appropriately. The engine will rev, pull, and then switch gears very roughly. This has been looked at by a local mechanic. The mechanic could not find any problems even though it has been a consistent occurrence. Mechanic stated that this is common in newer fords.
