I always felt the parking sensors were set too close to go off. Which I talked to the dealer about when I bought it, and he said it was the normal distance and I didn’t need to worry it would warn me in enough time that they would save me from hitting anything. And last night it proved my point, I was in the dark in a parking lot I was not familiar with, and while looking for an exit. I found one of the few rather large based light post which had the light burnt out. The sensors didn’t beep until after I hit it. I was just letting the car idle while moving. I now have serious doubts on their usefulness.

I've never had an issue with mine, use them every time I pull in my garage. I have a saw horse in front of where I park and use the sensors to know I pulled in far enough to clear door coming down. Only issue I've had is the elevation of them. If the object is too high they don't see it. Dropping off yard waste i bumped a semi trailer while backing up to unload. Luckily only a small dent and didn't hit that $1200 taillight. Live and learn.

By the way BLIS has nothing to do with the parking sensors. I'm not even sure it active at slow speed.

They do Lee, but the BLISS only pick up cross traffic, and vehicles in your blind spot. The reverse sensors get the stuff behind you. OP, I've never had a problem with the reverse sensors on mine either.

OP, could it have been the angle st which you were rolling towards the light post. I think (but don't know for sure) the front sensors are basically pointed forward, and could have not sensed the post at all. Just wondering.

I stand corrected, never though about the BLIS radar being the cross-traffic sensors. Makes sense.

It seems to me that the sensors pick up larger flat objects fairly well but vertical cylinders like round light posts don't do so well.

I suppose those round posts were designed for stealth.

I use mine every single day to get right up close to a large round light post at the front passenger corner of the truck in the parking lot at work. They do wonderfully at getting me to be within an inch or two of the post, and not have my butt sticking out into the lane like all the full-size trucks do.


As far as OPs issue... They only start beeping once you get within a couple feet and aren't active above a few miles an hour or so (not sure on the exact speed, maybe 5mph), so if you're going too fast you obviously won't have enough time to react nor will they even activate.

They're not made to help you navigate around a dark obstacle course. They're meant to allow you to creep up and park close to objects. That's why they're called parking sensors.

I was pretty darn close with my "couple feet" and "5mph" constraints statement/explanation it looks like. haha Pretty proud of myself for that. haha

No i was trying to find an rxit
Thanx for the information, I was doing about 12mph and my sensors didn’t chime until after I hit the rather large bottom of the light which was burnt out. It was drizzling and very dark as well when I turned to try and find an exit out. I feel the sensor should have worked before I hit it, instead of after. I’ve complained about this and other safety issues on this truck, which for some reason never works when I need it to but does when I don’t. Put at least 4-5k worth of damage. And there’s no modifications on the front it’s a 2 wheel drive.

so....you were going forward and hit the light post?
I was driving diagonally slightly, and looking forward and alternating to the side to find a way out of the parking lot where the stores had almost all closed. I’m guessing the light was out from neglect or the quit paying their light bill.

Yeah I got one on the drivers side that picks up cross traffic randomly passing behind me on that side, but the passengers side works great. But if I’m parked and in reverse with the front facing traffic it picks up the cars passing every time. Weird. I also have never been able to get the mist windshield wipers to work. I know they turn on.

So you were outside the parameters (going too fast) for the sensors to work as designed and intended. Doesn't sound like a safety issue, design fault, or failing system to me. Maybe your truck has other issues, but this isn't one of them based on the information you've given.

No offense intended, I'm sorry the manual clearly states less than 5 mph and a sensing distance of 28 inches. Even if they had gone you would not have been able to stop in 28 inches from 12 mph, even if they are enabled at that speed. Sounds like they were working as intended. They are parking assist not collision avoidance. That uses the camera up by the rear view mirror and the ACC sensor if you have one. Probably activates at a higher speed.

I know not what this thread is about but what do you mean by mist windshield wipers? If you are talking rain sensing, does your truck have them? Not all do. If yes read that section of your manual.
