2015 FORD MUSTANG — Complaint #1759078
Open-data reference.
NHTSA Complaint about EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH filed July 23, 2021
NHTSA complaint #1759078 (ODI reference 11426077) concerns a 2015 FORD MUSTANG and was filed on July 23, 2021. The owner reports the failure occurred on July 20, 2021. The report was geocoded to Georgia based on the filer's self-reported location. The affected component is categorized as exterior lighting:brake lights:switch, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same FORD MUSTANG cohort independently describe similar exterior lighting:brake lights:switch failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2015 FORD MUSTANG shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
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 replaceme
