| Blind Spot Detection problems |
2024 GMC Yukon intermittently experiences complete loss of audio while driving. During the failure, all audio sources stop working, including radio/music and incoming hands-free telephone audio. During a phone call, the other party can hear me, but I cannot hear them through the vehicle. When this failure occurs, the audible turn-signal click/clack also does not work. In addition, the audible blind-spot warning does not sound. The visual indicators continue to function, but the associated audible warnings are lost. The condition is intermittent but persistent and can last 30+minutes. Gm has issued a technical service bulletin addressing loss of audio together with loss of the turn-signal click/clack on 2023–2024 GMC Yukons. I am concerned that this is a safety-related defect because the audio-system failure results in the loss of audible driver warnings while the vehicle is being operated.
This is a post-remedy failure of recall 25v-274 (GMC 6. 2l l87 engine). Following a full engine replacement performed by the dealer under this safety recall, the vehicle has suffered a catastrophic electrical compromise. The vehicle is currently throwing codes p2534 (low ignition voltage) and u3018 (bcm communication). Safety hazards: the vehicle experiences sudden loss of power, engine stalling at highway speeds, and total failure of the exterior turn signals (hyper-flash). The ac system has been disabled by the body control module due to low voltage, creating a hazard in high temperatures. This vehicle fits the exact profile of NHTSA recall query rq26-001 and engineering analysis ea25-007. The manufacturer's remedy for the safety recall has failed to restore the vehicle to a safe operating condition, and the dealership is attempting to charge diagnostic fees to investigate their own defective recall workmanship.
