Issue: total failure of frontview camera adas sensor, disabling automatic emergency braking (aeb), front pedestrian braking, and lane keep assist. Technical evidence: gds2 telemetry confirms a "no communication" status for the camera hardware. Core safety modules including the electronic brake control (ebcm) and the inflatable restraint (airbag) sensing module report active communication failures (dtc u026a/u216a). These safety-critical modules are currently unable to receive the sensor data required for crash avoidance and occupant protection. Forensic timeline: vehicle nvram reveals a manual "clear codes" event occurred at 46,838. 3 miles—exactly 0. 4 miles after the sale contract was signed. The fault reappeared with a 0 km offset (immediate return) and has been active for 162 ignition cycles, proving the defect existed throughout the dealership's possession. Dealer response: the selling dealer delivered the vehicle with an unsigned 125-point inspection. Despite being presented with gds2 telemetry proof of the braking and airbag communication blackout, management refused repair, mischaracterizing the disabled emergency braking system as a "luxury feature" and claiming the vehicle is "safe" to drive. Symptoms: "service front camera" warning, intermittent loss of hvac controls, and gear display (prndl) blackout due to systemic serial data bus interference caused by the hardware failure.
I was driving on a highway access road when my chevy bolt's automatic emergency braking system suddenly and unexpectedly applied the brakes. I have noticed that the proximity warning system is fairly sensitive - often beeping even when I am applying brakes to decelerate at a rate that feels comfortable and reasonable to me given the distance of the vehicle in front of me. In this instance, however, there was no beeping of the warning system. Additionally, I was not closing the distance between my vehicle and the one in front of me, nor were they braking. I was concerned that the unexpected and unnecessary emergency braking could have caused me to be rear-ended had a vehicle been behind me. It was very heavy braking - disproportionate to the distance and speed between myself and the vehicle in front of me.
