1 Exterior Lighting problem

Failure Date: 11/26/2024

This car has one pedal driving (opd) which allows you to slow the car to a stop, without using the brake pedal. The car activates the brake lights, based on sensors in the car which sense the deceleration. In this mode, the brake lights are not activated by any pedal action by the driver, only by the vehicle's actual deceleration. This all works great except the fact that once the car comes to a stop, the brake lights turn off. This is obviously a hazard for any stopped driver and there are anecdotal cases of rear end collisions caused by the lack of brake lights. This problem is fixed in later models of this car. I presume that this issue could be fixed by a simple software update.

2 Exterior Lighting problem

Failure Date: 05/01/2024

In all models before 2022, the brake lights shut off while at a stop in one-pedal driving mode. This is a major safety concern that can be fixed entirely in software.

3 Exterior Lighting problem

Failure Date: 06/27/2021

I have had people following me, and almost hit me when stopped at a stop sign, or waiting to turn left, because the brake lights go off while the car is still being held to some degree by electric motor braking. When driving the car in l mode, one pedal driving, the brake lights come on when decelerating, but when stopped they turn off. The issue is, there is some electrical braking applied when stopped at a stop sign or light, even with no foot on the brake pedal. The car will hold on a slight grade when in l, with no foot on the brake pedal. As far as I understand the law, if there is service braking being applied, the brake lights must be on. I also believe that the electric motor holding back is considered to be service brakes on an ev. I've heard gm corrected this issue on the 2022 models, and I think it should be corrected in the earlier models. Another issue is tall vehicles following close behind me don't see the turn signals because they are in the bumper, mounted very low. I've had people blow the horn at me several times for turning, when they did not see my turn signals. They are working properly, just too low for some vehicles to see when they are close behind. The turn signals are separate and are much lower than the brake lights.
