As posted previously this new petition will likely be dismissed as I don't think Teslas SUA problem is easily fixed as Dr. Belt suggests. Furthermore, Tesla is aware of its SUA problem, trying to fix it, and hasnt managed to yet.
What can cause the random negative voltage spikes is from induced currents from Electromagnetic Interference. As explained in the following quote, E3 wave (which is similar to conditions during a geostorm) causes voltage depression in power lines and it seems in Tesla system as well. Like regulators at a substation, Tesla system seems to try to make up for this voltage depression causing voltage spikes leading to SUA and logs recording high accelerator pressure even though the driver hasn't touched the accelerator.
