Rearview System Braking Problems of Ford Bronco

Getting a cross traffic alert and blind spot alert fault warning every time I drive the car.

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.

While driving I lost most/all adas system. I received several alerts that kept repopulating. No cross traffic working no blind sport working no cruise control no forward collision working no lane departure working I took the rear assembly by the taillight and rear bumper. The wires and electrical components are corroded. Koons Ford annapolis maryland is requiring $1520 parts and labor. . This is a major safety problem as it was not designed correctly. Many Bronco owners are going through this. .

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.

I have been getting a message that my blind spot and cross traffic alert deactivated because trailer is attached. I have never had a trailer attached but do have a trailer hitch- the dealer said Ford refuses to pay to have it fixed because the bumper to bumper warranty is out. The car has been garaged and has only 9,000 miles on it. This is a safety issue that I think they should cover as I have no blind spot or cross traffic warnings.

Cross traffic and blind spot monitoring/alert failed. Electrical wiring failed due to rubbing on the rear bumper causing failure of blind spot alert and cross traffic alert systems. Reliance on these systems is critical to safe operation of the vehicle.

Hello, I previously wrote about this problem under id#116588898 however I feel as though it did not explain what happened correctly. As I was backing out of my garage, I stopped my vehicle putting it in park. After putting my vehicle in reverse and looking in my mirrors I didn't see anything behind me. (a blind spot) I was on an angle. My radio was on and as I proceeded in reverse, I hit a car that was in my driveway. There was no damage to my vehicle however there is about $3900 damage to the car behind me where the spare tire crushed the trunk lid and rear left qtr. At no time did I hear any warning lights, the radio did not lower, and warning lights and sounds were not doing the job of what they were supposed to do. As I thought about it, I'm not even sure the camera was on. I hope this explains this a little better than id# 11658898. Sorry for the inconvenience of reporting this twice. If the other can be deleted that would be appreciated.

Backing out of the garage then stopping for a minute and putting it in park then in drive afterwards I forgot there was a car behind me in my driveway. After looking in my side mirrors I saw nothing. I hit the vehicle behind me. With the radio on and playing music at no time did the radio lower in sound and the avoidance system sound off. If the avoidance system sounded off the music was louder. I hit the vehicle behind me. I guess I should have turned my head to check behind me but if the sounds were going off it might have helped me to avoid this. I really can't remember either if the camera was on. Usually if the sounds start chirping I look towards the screen. There was no damage to my vehicle only the vehicle I hit. It was my rear spare tire that caused the damage on the other vehicle. I will need to take the family vehicle to get an estimate.

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.

I am receiving blind spot and cross traffic failure alerts in my vehicle dashboard indicating these systems are not working properly. This is a known issue by many Bronco owners. I believe its due to a bad installation design where the wires naturally rub up against the bumper and with weather exposure they are failing.

I had the cross-traffic sensor and blind spot detection sensors changed about a year after I bought my Bronco and the tech told me where the wires are housed it is wide open to the elements which cause the wires to fail. This was fixed under warranty and now 2 years later I have the same issue, and Ford will not fix since I am out of warranty. This is not only a design flaw but also a safety issue for someone who relies on those sensors to work.

The vehicle’s back-up camera completely malfunctions about 20% - 30% of the time making it completely impossible to see anything behind the vehicle when backing up. Sometimes, when the vehicle is put into reverse, the display screen will be completely dark, other times the image freezes on a load up image or screen and there is no display of what is behind the vehicle, and worst of all, other times the display will lock on the first image from the rear facing camera and not show real-time video of what is behind the vehicle, making the driver think it is safe to back up when it may not be. The vehicle has been brought to two different Ford dealerships three different times over the last two years regarding this problem. The first time I was told the problem had been addressed. The problem continued to occur. The second time, I was told the issue could not be addressed at that time. I was told that Ford corp was aware of the problem but they did not have a fix available at that time. I was told that Ford corp was working on software enhancements that would be available sometime in the future that would address the issue. The problem continued to occur. The third time I was advised the problem could not be addressed at that time and “Ford is working on additional software enhancements which are expected to be delivered over-the-air (ota) by late q4 2024” and “software will update automatically if vehicle connectivity is enabled in the vehicle’s settings. ” the problem continues to occur, so much so that I have several recorded videos of the problem occurring.

The vehicle will throw a warning saying the cross trafic collision is in operable. A Ford tech looked at it and said a wiring harness is chaffed causing blind spot monitioring and cross traffic collision systems to not work. Cost of the part only is $700, not including labor. This is a very serious fault, which could result in injury and fatalitys.

2nd day of ownership and rear view camera failed. Called Ford and they said it was two months until they have an appointment.
