Could someone please explain to me, why my parking sensors go off and alert me every time a little twig or stick is sticking out of the ground somewhere in the vicinity of my truck, yet they fail to alert me when an 8" concrete reinforced steel post is directly in front of them?!  Additionally, could someone please explain why hitting said post at 2-3 mph causes roughly $4,000 worth of damage?!  I think it's absolutely ridiculous that I spend north of $65,000 for a truck whose bumper can not withstand a 2-3 mph impact without causing that much damage.  I realize that I should have been paying closer attention, but the post was in my blind spot.  I never saw it.

Don't your backup cam work??

Blind spot?

 

It was in a parking lot and I was using my rearview and sideview mirrors instead of the backup camera so that I could see possible oncoming traffic easier out of my peripheral vision.

Sensors are a driving aid, not to be fully relied upon. Wait until auto braking puts the brakes on hard for the invisible man like I've had happen in my '20 Traverse HC. Now turned off after that incident and off in my Silverado.

I've heard of a similar issue happening with Teslas in a specific tunnel at a specific spot in California.  There's already been a serious multi-vehicle crash because of it.  Fortunately, my truck didn't come with all that fancy stuff.  The result of getting towing mirrors on my Trail Boss.  I did add front and rear cameras via GM Accessories for recording driving in the event of an accident, however they don't have control of the vehicle.  They only sound an alert if it thinks I'm too close to the car in front of me.  They also seem to alert me to some (not all) school zones and traffic cameras.

Agree.

Last weekend, while walking in the Home Depot parking lot, a guy in a new F-150 almost ran me over while backing out. His camare and/or sensors should have clearly detected me. He profusely apologized and said neither his camera nor sensors indicated anything. Damn Fords! :(

I use my backup camera more as I get older along with mirrors. I’ve had one too many neck strains tying to see everything. By turning around to look. There’s one device that’s been on automobiles forever. I look at them when there’s no choice but to walk behind vehicles. Backup lights. A great warning device. Getting run over by someone backing up could fall under the category of. It may be the drivers fault, but you’re dead if you get run over.

  I just purchased a chrome bumper for $150 (if I remember correctly) a few weeks ago off Facebook Market place.  The only damage you have is to the bumper so purchase a new one and transfer the sensors and plastics over yourself, its easy peasy.

That thought has crossed my mind, or at least some other after-market bumper that's cheaper than the OEM one.  While it isn't readily apparent from the picture, I did sustain a fair amount of damage in my rear quarter panel from it getting pushed in by the bumper that is beyond my ability to fix.

I apologize, I didn't see the fender damage.  Good luck with getting it fixed. 🍻

      Light Up the Trail From Above: 50" PRO for the Hummer EV

      By mandrautomotive · Posted

      Hey everyone,   For anyone looking at roof-mounted lighting for the Hummer EV, we wanted to share our M&R Automotive 50" PRO Roof Light Bar for the 2022+ GMC Hummer EV.   The curved 50" bar sits close to the windshield rather than sticking way up above the roofline. The mounting position is designed to keep the setup relatively streamlined while minimizing wind noise and maintaining full use of the factory windshield wipers.   A few details:   50" curved PRO light bar Fits 2022–2026 GMC Hummer EV Spot + driving beam pattern TIR optics White main beam Amber DRL backglow Approximately 15,410 measured lumens through the lens Mounts to factory accessory locations No cutting or drilling required Wiring runs down the A-pillar toward the AUX connections Designed to minimize wind noise Lifetime warranty Off-road use only     The 50" is an interesting middle ground for anyone who wants the visibility and mounting position of a roof bar without stepping all the way up to the larger 60" setup. For the Hummer EV owners here, would you go with the 50" for the lower-profile look or step up to the full 60"?

      Yeah, I've given up years ago with that! I was able to load a few when I first joined the site sometime around '07. Then after maybe 20 pics, it said I exceeded the limit. Now every pic I try to post says I've "exceeded 1mb".   ONE MB??? That's Windows 95 ******, lol!!

      I get the same results with pictures. Then I figure it out. Then I forget. Screw it.

      I guess I'm the only one on this forum who can't get effing pics to load here! Do you have to resize them to post, or am I just blocked from uploads?   I have the same luck with automotive electronics ... but this is the ONLY site on the net that I have this problem!   I'd post pics of what I'm working on ... but I CAN'T! 🤬       Just fabbed up the kickdown cable (had to extend the cable mount WAAAY out from the throttle shaft to get a full pull), and parts arrived for the fuel lines on the 940 carb conversion project. Should be able to drive this thing by the end of the day. If not for work, I'd have had this thing done SIX weeks ago.   Got the jetting sorted out last week. Had a real bad tip-in bog that I couldn't seem to correct. Friggin float height was over 11mm too HIGH! eBay purchase, so no wonder everything is screwed up right out of the box! I ended up with a larger dual-squirt accelerator pump jet anyway instead of the single. Also moved the 70 primary idle jet (4 sizes too big out of the box) to the secondary idle circuit, and installed a 57 in the primary. Runs great on the fuel bottle!    Still using the computer for ignition. Going to drive it first and see if I want to go through the project of installing an intermediate shaft with a distributor drive gear, so I can install a block-mounted distributor and run points, 100% computer free. I should do that anyway just from a simplicity / reliability / tunability standpoint. The electronics left me stranded last year a couple times! I can't tweak the timing to my liking right now because of the computer. Tried twisting the cam-driven distributor already ... and the damned thing just reverts back to where it was! That's infuriating. But if it runs well enough I might save that for next season.   Just driving it in and out of the shop to work on other projects, it feels 1,000% more responsive with the carburetor. Also fires MUCH faster when cranking. Can't wait to drive it and see if I got more than 114 ponies, lolol.   Hopefully these don't go 404 like the last post ... https://postimg.cc/gallery/MjhrmZS   Seems like that site went back to dial-up internet! Maybe they'll fix that some day ...
