2022 Expi Limited. Struggling with failure of the blind spot & cross traffic system. Started some months ago. Figured it was snow, dirt or mud on the sensors in the rear bumper. Washed the truck. Still fails. Sometimes it fails (dash warning - system disabled due to sensors being blocked) within seconds of starting the truck and moving. Other times it doesn't set the warning right away, but always within 5 or 10mins of driving. I've had it back the dealer twice. First time they performed a reflash. Worked halfway home, then failed. Second time the dealer says the problem is mud on the backside of the bumper, throw up from the tires. Indicated I need to wash the mud out - from the backside of the bumper, to get the system to work. I know this cannot be the case. The sensors are visible on the show side of the bumper. And they are clean.
Is anyone else experiencing this failure?
Here's some more odd & specific things I've found with the system. When the warning stays off for a longer period and I have a chance to drive alongside other cars only the left side is working properly. The right side will not detect a car or even pickup truck. A large truck or semi is detected. And eventually the system does set the warning light and disable. If I drive long enough, sometimes it will come back on. But again, only the left side properly detects all vehicles. Pretty dangerous situation actually. You think the system is working (no warning lights), but the right side will not warn you of anything smaller than a very large truck or semi in the blind spot.
