2021 Ford Bronco Lane departure Problems

“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.”

“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 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.”

“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.”

“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.”
