2017 Prime headlight failure

My left-side headlamp began flickering and intermittently going dark this past November. When it goes dark it triggers the check engine light. When I turn the headlights off the error code seems to reset.

Beginning in March the check engine light comes on every time the headlights are turned on.


I took it to our dealership to get some idea of what was wrong.

On 8 March 2025 the dealership says that I need to replace the headlight assembly and its computer. The assembly costs $1700 and the computer $200. With projected labor fees the total cost will be $2700.

For a failing head light, or I assume a loose connection [since it has been an intermittent failure]. This appears to be an extremely out of proportion remedy.
