There is a break pedal pad that is broken. It doesn't allow the car to accelerate correctly and car goes in limp mode. All break lights are illuminated when car is turned off. There is a recall for this, but I purchased my car in CA. I think the car was originally a Nevada car. Am I still eligible for the recall even if I didn't get the notification and my state of purchase was not mentioned?

The brake pedal stop bumper in my car disintegrated in the middle of the day and fell off. The brake lights do not turn off anymore and the vehicle can be started and shifted without needing to press the brake. I found a recall # 22S02 for this exact issue but my vehicle is not covered by it (assuming due to region). The vehicle has not been inspected yet.

NHTSA ODI 11594425

A plastic clip ("Brake Pedal Bumper") broke and fell out of place, causing the brake pedal to no longer reach the brake light switch. The brake lights now remain illuminated permanently, even with the brakes released. This also caused the engine and transmission to go into "limp mode", the engine no longer revving over 2,000 RPM, the transmission not shifting, and hill-start assist and traction control no longer working, making the car unsafe to drive. The brake lights will remain on even when the car is completely shut off and locked, draining and damaging the battery. It is my understanding that this is a known issue, and there was a recall for this in certain states. (Safety Recall 22S02, Regional Recall 22R01). There should be a national recall for this, as the affected part appears to be of low quality, and causes safety issues when it fails, with the car's drivability and lighting affected.

Third tail light and rear tail lights remained illuminated after the car was turned off. Driver discovered the brake light switch (rubber/plastic piece) had crumbled into the floor board preventing the tail lights from turning off, thus, becoming a hazard to other motorists on the road as the tail lights remained illuminated even while driving. While the vehicle was being driven, the driver could not accelerate to the appropriate speeds as the car was "thinking" the brakes were being applied and could only approximately drive at 40-50 MPH. The vehicle has been inspected and the above information was confirmed as the issue. No other warnings/messages occurred prior to the piece breaking.

My break light switch pad is broken and is causing the car to not maintain speed and sluggish acceleration. I have seen other drivers report the same failure with their cars.

While on vacation (my car was at home) a piece in my brakes broke and caused my break lights to be on constantly. When I tried starting my car the battery was dead. The break likes being on like they were ended up causing my battery to corrode by time I got home from the continuous energy drain. I was able to jumpstart my car but when I went to put my car in drive the vehicle would not accelerate over pretty much idling. When I got my car towed to the dealership (Gary Yeoman's) they told me the break bumper disintegrated and caused my break lights to be on and a vehicle acceleration override to be engaged.

Traveling on highway using cruise control at posted speed limit. Approached slowdown due to accident and applied brakes. Accelerated to limit (manually) after passing accident. I was in middle lane. Vehicle abruptly began to decelerate. Continuous pressure on gas pedal did not increase speed, so I put on hazards and moved to slow lane. No failures on dashboard and quick scan through gages did not identify an issue. Re-applied pressure to gas pedal wanting to get to next exit. Car sped up, but when approaching 50 mph, it decreased again. Found that pumping gas would allow me to maintain highway speed. Pulled into truck stop at exit and turned car off. Message on console "Hill start assist not available". Let vehicle rest 15 minutes, added gas. Quick web search seemed to point to problem with ABS sensor. Seemed to drive ok in parking lot and road leading to highway ramp. Decided to try to get closer to home. Problem occurs immediately after climbing to 50 mph. Cruise control won't work. By carefully monitoring speed and pumping gas into overdrive when needed, I was able to get home. Could not get appointment with dealership until late afternoon next day. Hill start assist message comes on again when stopping. After arriving home and parking in garage I went inside for about 30 minutes. Needed to unload items from car and went back to garage noticing that the strip of lights above trunk are still on. Got back in car, started it (got hill assist message), turned lights on/off and turned off car. Now my rear brake lights are also on. I had seen a post about this, so unhooked battery to prevent drain. Next morning, reattached battery and had same problem. After more internet investigation, Awesome humans who have also had this dangerous issue and provided a $5 fix instead of a $500+ dealership fix. https://www.mustang6g.com/forums/threads/brake-light-switch-near-pedal-failure.122100/pag SUDDEN UNEXPECTED THROTTLE CAUSING SLOWDOWN ON BUSY INTERSTATE IS LIFE THREATENING.

Brake light switch pad broke , So the car thinks the brakes are on so it goes into "limp mode" and it starts turning off assist modes.

The issue is the Brake Light switch stop pad on the brake pedal which is a rubber type of plug. At 70,000 miles the brake light switch stop pad cracked and fell into floor board (see pictures). When that happened, the RPMs dropped to idle speed and the car slowed down. After a few seconds, the car would pick up speed again only to repeat the event over and over again. I understand that when the brake light switch stop pad is missing and the plunger on the switch is fully out, the car thinks that you are applying the brakes. I was lucky, I was on a two lane road with no traffic, but I was headed to an inter-state with heavy traffic. Ford (nor does anyone else) does not sell just the rubber plug which fits on the brake pedal, but it will sell the complete brake pedal assembly. Not sure the reason that the brake pedal would require the hole that requires the rubber plug, but think that Ford should be responsible for the replacement or a better solution for the repair (Provide a replacement plug, not just the complete Brake pedal assembly.

Brake pedal pad failed, causing car to suddenly brake even though brakes were not being applied. Ford Dealership recommended replacing brake light switch assembly. Brake lights stayed on even after the car was turned off. Had to disconnect the battery to prevent drain.

I'm on highway going 70mph and all the sudden my car slows down drastically to about 35mph and won't accelerate any higher. I almost caused an accident. After I got home I also noticed my brake lights would not go off, even after the car was off for a bit. I had to undo the battery.

While driving and pressing on accelerator pedal car slows down without pressing the gas as if the car is about to turn off. This is a very dangerous hazard as I am in the middle of a highway which can cause an accident if it does turn ofd. I noticed that the brake lights are on 24 hours a day whether the vehicle is off or on , this could be the issue, something is either jammed in the engine system or the brakes sensors are messed up and are not telling the rest of the car that the car is on and moving. There is no messages that are telling me inside the mustang that something is wrong with my car . I have had my car 6 years and this is the first time I see this happening.

Plastic clip for brake light switch disintegrates over time, causing reduced power and inoperative brake lights.

The brake light switch function was inhibited due to the plastic retainer mounted on the pedal assembly. The plastic retainer had become brittle and caused it to come apart in pieces. The retainer acts a point of contact for the brake light switch plunger which signals to the ECM when the driver is applying or not applying the brakes. Symptoms of failure are constant illumination of rear brake lights with vehicle on or off. Disables cruise control. Also most importantly it limits throttle control by reducing throttle range spraticly. No driver warnings or lights are displayed or illuminated on the IPC. Problem has been verified and reproduced by independent service center.

A NON-CONDUCTIVE PAD IS INSTALLED BETWEEN THE BRAKE SENSOR SWITCH AND BRAKE ARM. THE PAD BECOMES BRITTLE OVER TIME AND BREAKS ALLOWING THE BRAKE SENSOR TO ENGAGE. THIS CAUSES THE CAR TO GO INTO 'LIMP' MODE WHICH CAN OCCUR WHILE DRIVING ON HIGHWAYS. THIS IS A SAFETY ISSUE SINCE IT OCCURS RANDOMLY AND CAN HAPPEN AT HIGH SPEEDS.

NHTSA ODI 11416202

BREAK SWITCH PAD IS REALLY EASY TO BREAK. BREAK LIGHTS STAY ON AFTER CAR IS STOPPED AND IN PARK AND CUT OFF. WHILE DRIVING VERY DANGEROUS GET NO POWER TO SPEED UP AND WHEN YOU HIT THE GAS NOTHING.

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.

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.
