Brake Light On Problems of Ford Mustang

My battery died and required a jump the next morning. When I began driving, the car was throttling down as I was attempting to accelerate as if the engine was losing power. I didn't feel safe driving so I returned home and notice that my rear lights including the brake light stayed illuminated even when the car was off. I had to disconnect the battery in order to save my battery from draining again. After some investigating I found the brake switch pad was broken and this is what was causing the brake lights to be on all the time and causing the lack of engine power. This issue was not allowing the car to accelerate because the throttle is over-ridden by the brakes. The car was thinking the brake pedal was being pushed at the same time as the gas pedal. The brake switch pad breaking and causing this problem is very dangerous. I'm so lucky it happened on a local road and not the highway. I've read multiple accounts of this happening to other people. Ford needs to issue a recall and get this fixed to avoid major accidents.

The brake pedal stopper failed. The brake lights stay on all the time, you are unable to accelerate safely. This is a driveability and safety issue and poor design. This occured while driving on street, when I stopped is when I noticed the brake lights on after 15 minutes being stopped. I restarted car and attempted to accelerate but unable to effectively. I had a vehicle follow me around block and the brake lights were on all the time. Had vehicle trailered to the Ford dealer for diagnosis and repair. This vehicle has only 1857 miles on it.

The contact owns a 2020 Ford Mustang. The contact stated that while driving at various speeds in cruise control, the brake warning lights failed to illuminated properly. The vehicle had not been diagnosed or repaired. No dealer was contacted. The manufacturer was not made aware of the failure. Nhtsa campaign number: 20v573000 (service brakes, hydraulic, service brakes) was a possible solution to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 6,740. The VIN was not available.

Brake lights stay on after releasing pedal, sometimes also after parking car and turning off.

Suddenly started experiencing a loss of power at highway speeds only remedied by slamming the accelerator to the floor which then caused the car to surge forward. After getting the car home also noticed the rear brake lights would remain on at all times. The twin problems ended up being connected. Turns out there is a small plastic/ceramic piece in the brake assembly that fails and breaks apart without warning - also no dashboard warnings after it fails. Causes the vehicle to think the brakes are being applied and cuts the power in response. This happened while traveling at interstate highway speed and was an immediate safety issue. Was told by the dealer this small part is very susceptible to florida heat - unfortunately the whole brake assembly has to be replaced.

Vehicle was sitting in driveway. My husband returned from an errand and noticed my vehicles brake lights were on would not turn off, even with the vehicle power off. I found broken plastic pieces on the driver side floorboard. When I researched the problem, results show this is a broken brake light switch pad. Missing this piece makes the brake lights remain on and the vehicle is unable to accelerate, creating a safety hazard.

The plastic brake light switch pad located on the brake pedal arm deteriorated and fell apart. After the pad was gone, the brake lights would not go out. It may also affect the traction control when the brake light switch stops working. This is a common problem after about five years. I noticed this defect right away, otherwise the battery would have gone dead. The specific part is not available from fors so they want you to replace the whole brake pedal assembly. The new one has the same defective part installed. This is a dangerous defect. It is also very expensive to repair.

There is a small pad on the brake pedal between the pedal shaft and the brake light activation switch. This pad shattered into small parts causing my brake lights to remain illuminated even when I wasn't braking. There was no warning provided by the car that the brake lights remained on. The lights were on when driving, when parked with the vehicle running or not running. I believe it broke while driving the vehicle but I can't be sure. There are multiple pads within the pedal cluster on the clutch and other pedals that are the same part and may be prone to failure. The attached photo includes the broken part and a picture indicating the empty spot where the part is missing.

Brake light stop pad broke into multiple pieces while driving, causing the brake light switch to malfunction. Brake lights remained on even when pedal is not depressed, which causes various performance issues due to the ecu believing the brake pedal is being depressed. Brake lights remained on when car was turned off.

The brake light switch plunger broke off the brake pedal causing the brake lights to constantly illuminate. This is a safety hazard for poor design substandard material.

The brake stop pad spontaneously shattered on my '15 Ford Mustang v6 while driving. The car lost power: would not exceed approx 1500 rpm, throttle unresponsive, no check engine light (mil). I was driving on a two way road and suddenly lost power as I was approaching the 75mph section from 55mph. The tractor trailer behind me could have rear ended me if they weren't paying attention. Fortunately, when the pad broke, the brake lights illuminated despite not depressing the brake pedal. Other drivers were aware there was a problem immediately before I turned on the hazard lights. With the pad broken, the tail lights will not turn off even after engine shutdown and the button-start ignition bypassed the need to depress the brakes to start the engine. It is dangerous to be able to start the engine without needing to engage the brakes. Many people have had this problem but it is difficult to troubleshoot since there's no mil or dtc codes. Third party replacement pad cost $2, but Ford, apparently, only sells the whole brake assembly for $200 and costs up to $900 to have it done. People have opted to use zip-ties or disc magnets instead. Vehicles with this brittle brake pad need to have them replaced ASAP. It seems '15 vehicles are failing after 3-4 years. The sudden loss of power and bypassing the button-start ignition safety features makes this a serious issue. Owners with this issue seem to live in hotter regions like texas or florida.

Paint bubble on hood, replaced 3 right window motors, low pressure fuel switch, little plastic button on brake lever deteriorates cause brake lights to stay on causing car not to accelerate properly. Car only has 39000 miles on it!! window motor, pressure switch and brake lever cost $2000. 00 to repair. Really upsetting spend over $30000. 00 for a automobile than within 39000 miles and I need to spend this kind of money.

My wife notice the brake lights were stuck one. Tired several different steps to see if the problem could be remedied. Such as starting the car, locking unlocking, nothing seem to care of the issue. After doing some research online on one of the Mustang forums there were a few people that had the same issue. It seems that there is a little white plastic button on the brake lever that depresses the brake light switch. This seems to dry and crack and fall off the pedal assembly ,see attached photos. So instead of letting the car set all day and drain the battery I had my wife drive the car home. On the way home she experienced a running issue the car seem to shutter would not go above 30 to 40 miles an hour. Fortunately it was all side roads on the way home. If this had happened going down the interstate it could've been a big problem. From what I've read apparently the car goes into limp mode? sensing that the brakes have been applied? from the research that I've been able to look into the little plastic button which is probably about two dollars to produce is not available separate. The only way that this can be replaced is a brake pedal assembly which I read is approximately $300 plus labor. Some people are purchasing a rubber clutch pedal bumper from Toyota and putting in place of the plastic one Ford had. My major issue is that if she was on the interstate in the car slow down to 30 miles an hour who knows what could've happened. I believe this to be a safety issue since the car does not run properly when this part fails. I've been told the replace pedal assembly has been upgraded from the original part.

The stop pedal pad brok and the brake light were always on. The car stopped braking at all suddenly! I did not crash because the loss of braking happened while parking in a low transit street. Firts there was loss of acceleration randomly in a highway. I found the pieces of the brake pedal pad in the car floor. This is a severe risk factor for crash because when the stop pedal pad brakes the car will not brake suddenly.

Tl the contact owns a 2015 Ford Mustang. While operating the vehicle on a busy highway, the speed would not exceed more than 40 mph and the rear brake lights remained illuminated at all times. The vehicle was taken to mullinax Ford (1210 n lake blvd, lake park, FL) where it was diagnosed that a sensor in the brake pedal was faulty and the brake pedal needed to be replaced. The brake pedal was replaced and the failure was remedied. The manufacturer was not notified of the failure. The failure mileage was 30,000.

The incident took place in last summer. My brake light switch pad broke into pieces while I was trying to merge into a city highway from a freeway. Suddenly I could only accelerate for 2 seconds whenever I step on gas, and I also noticed my brake light never stops even after I turned my car off. I almost got into an accident and got killed. This problem is a very common problem among new Mustang models after 2015. Ford is not doing anything, and they would charge you $200 for the whole brake assembly while I only needed a 50 cents plastic pad. My dad is a car mechanic, and he was surprised that a car in 2015 would have a such common problem in 90s.

Brake lights would not shut off and stayed on steady so people behind could not tell whether or not I was braking . . . . When driving car would drop speed for no apparent reason like it was going to stall out. I found small plastic debrie on floor mat I guess it was a washer type thing from brake switch brittle and broken is pieces? this all happened while driving.

When driving the brake stoplight switch pad that attaches to the brake pedal assembly fails due to it being brittle plastic. This causes the on board computers to believe the brakes are being applied and drastically slowing the vehicle down from highway speeds to less than 50mph and preventing acceleration. I was accelerating to interstate speeds when the vehicle suddenly felt like the brakes were applied. This reduced my speed from 60 mph to 47-50mph with traffic behind me. It also illuminated the brake lamps on my vehicle which made it appear other drivers I was stopping abruptly. When I came to a stop I could accelerate up to 35-50mph however it was intermittent acceleration as the car would lurch forward and slow down. My brake light were on the entire time confusing other drivers. Pieces of the broken brake light stop pad were found on my floorboard once I was able to navigate the vehicle home.

Abs brake light is on this is unsafe in wet or snowy conditions.

Brake light and traction control light and abs light intermitten. . Then on constantly. . . Hasnt been fixed too expensive. . . In wet weather, slippery, icy weather tires spin because traction control does not work. . . Abs control module went bad. . . Thousands of people have blogs and forums complaining about this part. . . I will post this website with hopes they all complain!.

With absolutely no prior warning the brakes just failed to respond. Next time I turned motor on the brake light came on. If an accident had happened the warning would have come too late. Lost all the brake fluid.
