I have 2 rear object detection sensors that need to be replaced. I was told that that corrosion on those wires will eventually lead to larger problems, like the car not starting. Do these detection systems really have that large of a future impact? Seems a bit wild, considering their purpose. I want to get them fixed but at the cost of $1250 (including harness). I want to know I’m protecting against something larger than not being able to see a trash can in the driveway.
