While driving home, driving speed was 55 mph, car engine bogged down and orange wrench icon illuminated on dash. I was not far from home and was able to continue and "limp" home. Car would not go faster than 10-15 mph. When I parked car in garage and shut car off, the brake lights stayed on. There was no warning lights or anything wrong with car before incident. Car has not been inspected by dealer or service center. Doing further research online, I was directed to look at drivers floorboard for plastic pieces. I did find broken, yellowish colored plastic pieces on floor board. According to others, which have been experiencing the same issue, the brake light switch stop bumper pad has failed. I was able to find a recall (Safety recall 22S02) that has been issued for this problem, but the recall is region specific. I do not live in the regions listed in recall.

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?

Hi, I was driving on the freeway and suddenly my car stopped accelerating. I would push the acceleration pedal but it wouldnt speed up. And for a few times it would speed up very much. This was very rapid fluctuation. I also noticed that the cruise control was not working. This was very scary being on the highway with this kind of speed fluctuation. After i came back home, i noticed that the brake light wouldnt turn off at all. After doing some research i found that the brake light switch broke and the car was sensing that the brake was being applied and hence was doing acceleration fluctuations. I also found out that there are many other same vehicles which has the same issue.

Related to Regional Recall 22R01, the rubber bumper on my brake pedal that engages the brake light switch failed and placed the vehicle in a low power mode. This failure occurred while merging onto the interstate and almost resulted in my being rear-ended by a semi truck. Having never been notified of this regional recall, I was able to verify this was the case after searching forums and YouTube and identifying the pieces of the broken bumper in my floorboard. I find it to be HORRENDOUSLY unacceptable that this was allowed to be handled as a regional recall and no notice was ever produced, as it is a safety-related issue that could have resulted in grievous bodily harm. I am located in Kentucky, which is not part of the named region.

I was driving home from work and all the sudden it went into limp mode, I could barely get her home. Then I found yellow pieces of plastic in my floorboard. My brake light would not go off so I had to unplug the battery. Very scary to have that happen on the interstate, luckily I got off on an exit.

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.

I ran into the existing issue described in "Part 573 Safety Recall Report" NHTSA Recall Number 22V-011, but in a state not listed under the recall (vehicle purchased used in Pennsylvania in 2017). As a result of this part failing, my brake lights remained engaged permanently, and the car's engine power would increase and decrease rapidly (presumably because it thought I kept hitting the breaks). At time of writing I still have the broken pieces of the original part. I plan to take the vehicle into service within the week. There are no warning lights when this occurs since everything I'm the car is technically "operating correctly" - it just thinks the breaks are engaged constantly, and so has erratic behavior. The original recall lists high humidity as a cause, which Pennsylvania definitely has. I keep my vehicle outside 24/7, so it has definitely been part of many temperature swings.

This is a known issue on the 2015 Mustangs. The recall only invlolves vehicles from certain states with high temps and or humidity but does not include the state of Missouri which sees both high temps and high humidity. Dtc code P0504. Brake lamp switch has already been replaced and no issue with wiring. Positive the plastic stop bumper is the issue.

The little rubber pad that it attached to the brake pedal disintegrated. Without that pad the vehicle goes into limp mode and won-??t drive over 40. Don-??t know why the brake switch is connected to other electronics in the vehicle that would make it go into limp mode. Very unsafe while driving on the highway.

The plastic break switch pad broke when I was driving on the highway. I lost engine power and RPMs were erratic. Brake lights would not turn off even when brakes were not applied. I could not excellorate normally or maintain speed. Upon examination the pad was brittle and yellowing. There is already a safety recall for this part but only in certain states that does not include Arizona.

What component or system failed or malfunctioned, and is it available for inspection upon request" The break pedal stop pad broke into small pieces while I was driving today. My car suddenly would not go above 40 and while going up a hill I couldn-??t go faster than 20. When I finally got home I realized that my break lights would not turn off. I did google and it said to look on the floor board and see if there was anything on the floor. The pieces I found were identified as the break pedal stop pad. Yes it is available for inspection and I took pictures of the broken bits from the floorboard. How was your safety or the safety of others put at risk? My car suddenly was unable to go the speed limit in 6 o-??clock traffic putting me as well as those driving behind me in danger of a collision and physical harm. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" A message did pop up that said uphill break assist unavailable within 5 minutes of me getting in the vehicle. I had no previous issues or warnings before this incident.

Rubber stopper on brake sensor dry rotted and broke off. This caused the car to think I was applying the brakes when I wasn-??t. It would cut the throttle while trying to maintain speed and my brake lights were always on even though I wasn-??t touching the brakes or in the car for that matter.

There is a circular pin in the brake pedal that interacts with the brake switch sensor that basically disintegrated. Not having this part does not allow me to brake properly and caused me to get into an accident and would not allow my car to accelerate properly. Also, without this part the car will not turn off. The dealership told me that they had never seen this issue; however, I have found many incidents on the internet where this is a common problem in Ford vehicles. There were no warnings at all.
