Chevy Trailblazer brake lights

They are destined from the beginning.

This one kind of was, I agree.

if you read my original quote, I was asking the question:

"but is it a known issue with TrailBlazers as well?"

...and if you read the V1 manual (this is cut-and-pasted verbatim):

Laser False Alarms

1. Red neon, from stores and occasionally from brake
lights of other cars (example: Chevy TrailBlazer,
GMC Envoy, Olds Bravada and Buick Rainier), can
imitate the characteristics of speed laser.
Solution: Move away from source.

2. The electrical systems of some cars generate
electromagnetic interferences, triggering laser alerts.
How to test: Try V1 in a different car.
Possible solution: Try relocating detector within the
interfering car; also, your dealer may have a factory fix.

3. Adaptive cruise control systems using laser may cause
laser alerts.
Solution: Switch to normal cruise control.

Doesn't get much more known than that.
