I was driving in the northbound left hand lane on creasy lane in Lafayette, Indiana, approaching Rome Drive. A driver from a side street took an illegal left hand turn to head towards the northbound lanes of creasy lane, I was traveling over 30 mph, maybe 40 at the time of the collision. I was unable to see the other driver until it was too late as they passed by drivers turning from the right hand lane onto the side road they had been at. My airbags did not deploy during the collision, nor did my pre collision assist alert nor did my brake system engage. I suffered extensive front end damage at the time of the incident. There was a previous recall for my airbags in this vehicle, as well as notifications in 2024 that my collision systems had been disengage during warranty work.

The digital gauge cluster where it shows sensitive information is a blacked out screen. I took it an automotive shop to investigate the issue. They ran a diagnositic and confirmed the screen is receiving power, fuses are good, but the screen is not powering up. I cannot view the digital speed, fuel gauge, mileage, access GOAT modes, view tire pressure, view oil life, and other critical data, etc. This first occured a few months ago and would randomly turn back on, but not the screen is black more than it is on. Luckily I am able to track the fuel gauge (miles to empty) on the infotainment screen.

3 separate safety-related components have failed on my 2021 Ford Bronco, all of which correspond to open federal safety recalls that remain unremedied: 1. Infotainment/APIM Module & Backup Camera System (Recall Campaign 26V124): my infotainment screen fails to turn on, particularly in high-temperature conditions. When this occurs, the rearview/backup camera is completely non-functional. The vehicle displays no image when in reverse gear, eliminating all camera-assisted visibility behind the vehicle. This directly matches the conditions described in Recall 26V124, issued March 4, 2026. No remedy has been provided. 2. Digital Instrument Cluster / Dashboard: my digital dashboard intermittently fails to illuminate at vehicle startup. This occurs randomly and without warning. When it fails, the driver cannot see critical safety information including current speed, fuel level, engine temperature, or any warning indicators. Video documentation of this failure exists. This component is available for inspection upon request. 3. Low Pressure Fuel Pump (Recall Campaign 25V455): my vehicle has stalled on multiple occasions while in motion. During stall events, all dashboard warning lights illuminate simultaneously. This is consistent with the fuel delivery failure described in Recall 25V455, issued July 8, 2025, which states the fuel pump can fail causing loss of fuel pressure and an engine stall while driving. No remedy has been provided since the recall was issued in July 2025 (~9 months ago). All components are available for inspection upon request. However, the authorized Ford dealership in the area has refused to accept the vehicle for service or inspection, citing parts unavailability. Engine stall while in motion. my vehicle has stalled multiple times while being driven. The driver works as a real estate agent and regularly transports clients in this vehicle. The engine has stalled with passengers present. A sudden engine stall while driving results in immediat

My BLIS module on the passenger side does not work and I have a constant warning light displayed that there is a system malfunction. Under further investigation, this is a KNOWN design issue caused by the rear wiring harness that contains the BLIS sensor rubbing against components in the rear bumper. My vehicle has 31000 miles on it and is now out of warranty. Ford dealers are aware of this issue but claim it is not a recall and not under warranty. This is a safety issue.

The wiring harness is rubbing against the bumper, causing it to wear and eventually cut through. This causes an error to my BSM/Cross Traffic alert. I have an extended warranty, but it doesn't cover it. This is a problem I have seen on the Bronco6G forums.

I received an alert on the dash stating there was an issue with the blind spot monitoring/rear cross traffic system. It was erroring off and on for that entire drive. When I got home, I googled the issue and it appears it's a known issue with '21 and some early '22 broncos where they factory installed the blind spot module wiring harness too close to the rear bumper. Over time, the wires rub and eventually rub bare and corrode or short out. I went out to take a look and sure enough, I had rubbed through on the driver side (photo) and the passenger side was nearly rubbed through. I have an extended warranty and it's at the dealership today. This is a manufacturing defect and should be covered (even if out of warranty) in my opinion. We will see what kind of story the dealer can come up with to wiggle out of it being covered under warranty.

Bronco wire corrosion cross traffic refers to a known issue where wiring under the rear bumper, often for the blind spot/cross-traffic sensors, chafes, frays, and corrodes, causing system faults and failures, sometimes due to design flaws or environmental exposure to salt, requiring inspection and repair of the harness. This problem triggers error messages like "Cross Traffic System/Blind Spot System Fault" in the instrument cluster, impacting safety features, with potential fixes involving harness repair, protective sheathing, or sensor replacement. My car’s wiring was corroded due to this flaw and required a repair exceeding $1,000.

Location of wiring from the factory for Blind Spot Warning and Cross Traffic Alert systems is not protected. The wiring has frayed and broken due to the wiring being unprotected, loose and rubbing on the rear bumper, causing the systems to not function. This is a blatant design defect from the factory, causing two safety systems to fail. Reporting now as, to the best of my knowledge, the manufacturer has not issued a TSB or recall and dealerships have acknowledged the issue.
