4 Signs Your 2017-2019 Buick LaCrosse Needs Sensors, Cameras and Driver Assistance Work

Most sensors, cameras and driver assistance problems announce themselves well before they strand anybody. On a 2017-2019 LaCrosse, these are the ones worth acting on.

1. A TPMS light that will not clear after a tire rotation

This one is usually early, which is good news, because it is cheap to fix early. Start by looking at front camera modules.

2. A lane keep or forward collision system that reports as unavailable after a windshield replacement

By the time this is obvious you are generally replacing more than one part. Start by looking at front camera modules.

3. A backup camera image that flickers, goes blue, or shows lines

It rarely gets better on its own, and it usually gets louder before it gets expensive. Start by looking at front camera modules.

4. A park assist system that disables itself in cold weather and comes back warm

By the time this is obvious you are generally replacing more than one part. Start by looking at blind zone modules.

What to Do Next

TPMS sensor batteries typically last seven to ten years and are commonly replaced as a set during a tire change.

Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.
