Wicked rear passenger head impact!! Updated JL crash test. Where is the rear side curtain?

[The Bean]

I would be content with this argument if a video didn't exist depicting a pretty horrendous head bash. Considering the technology and modern engineering that exists today, there's no reason for rear-seated passengers to eat shit and suffer gnarly head trauma unnecessarily. It's a lazy argument and I believe it's fandom clouding judgement IMO

if you think the impact that crash test dummy took in the JL was bad, go look at the test footage from larger “family-focused” vehicles. There’s no “fandom clouding judgement” here. I never said that what the results showed was inherently “acceptable”. But the JL test dummies faired better overall when compared to far more popular vehicles that are targeted directly towards families.

Still will require calibration. Any idea if it's a static or dynamic ADAS sensor array?

Actually that process is built in. Mine did NOT need calibration. There seems to be equating Jeep with other vehicles all too often.
Calibration is software, put it in calibrate mode, drive it, it's done.
And since it's mounted to the frame in a very real respect, it's not going to need anything in many cases.
I had mine replaced. The glass isn't more expensive, just a different part number.

I've had my windshield folded down and back up - everything still works perfectly.

Not in my case - I couldn't care less about that part for many many reasons - not the least of which is I did NOT buy a Grand Cherokee or a Lincoln, I bought a truck, 99.99999999% of the time there's no one and nothing back there.
If I wanted something to haul kids or passengers around in, I'd maybe looked elsewhere, but maybe not, too. You can only protect yourself so much in this world. If that concerned, wrap yourself in bubble wrap.

Those tests are so very specific, the odds are still with the people in the back. Boy people are getting weird over this.

Why buy one if you are so pissed about it? Huh?

I guess you have to upgrade vehicles every year - can't have any risks, now. The 2024 models will have a quantum force field that repels all impacts.

Man, how did our parents ever survive. How did we ever survive growing up?

I'm all for safety, but to bash a company because a niche vehicle aimed at a specific market isn't the safest in the world - and yet, here you are, it's hard to understand.

Unless OEM has NASA level tolerances for glass thickness (they don't) it will still require calibration

No, it won't.
Been all through that in several other threads.
Even if there was a problem it's not a big deal - put it in calibrate mode and drive it.
More than just me have had the glass replaced -no calibration. Techs have even said - usually not needed.
In fact, the calibration isn't even mentioned in the end of the tech doc explaining windshield replacement. Nowhere does it say "continue on to calibration".
These things use camera and radar in conjunction with each other and are pretty sophisticated.
Anyway, there's been at least 2 years of covering this......... in multiple threads.

As an aside, they sure seem to work fine with rain on the glass, or even a certain amount of snow or ice, so......... they must be a little bit forgiving.
A wet windshield will be more distorting than a different piece of the same glass.

two safelite quotes. one checked ADAS one check no ADAS. $723 and $329 respectively

Okay, first of all the JL is NOT an SUV, yet they continue to throw it in that category.
Go to your high end, safety first sedan convertibles, and show me where the rear curtains are.

Secondly, the windshield, nanny safety, and re calibration. If there is no impact to the windshield right in front of the nanny sensor, there is no need to re-calibrate the nanny sensor. The JL and JT were designed to have their windshield folded over and driven. If there is ever a need for re-calibration, it would be after lowering, driving, and then raising the windshield. It's not needed then so it's not needed for a simple windshield replacement.

The nanny sensor doesn't touch the windshield, is recessed from the windshield, and doesn't need calibration every time a squirrel farts in it's general direction.

But, the safety sensors are not intended to be used with the windshield lowered; remember that little cover for the sensors, to keep stuff out? It does a pretty good job of disabling the sensors, too.

Is that with recalibration or just the cost difference of the part numbers?

Don't snip and chose. Quote the whole section and argue.

AGAIN, the sensor is NOT attached to the windshield. Unless there is a DIRECT IMPACT to the glass at sensor location, then no need to re-calibrate. The sensor and windshield have NOTHING to do with each other.

Likely the part - I forgot that the DASM windshield has a defogger built into the windshield where the camera looks through. So there are places for a couple of wires on the glass.

The calibration itself is all software and driving - I was just looking at prices and that runs $45 on up. It takes 5 minutes once you have the computer hooked up (assuming traffic allows you to drive as needed)

Any time the weight of the vehicle, the ride height, etc. are changed, then a calibration is needed. That means anyone like me who has swapped springs, changed tires, put on a heavy bumper and winch, we're in trouble, the system must be calibrated. Yup, that's what it says - changing the ride height, rake of the truck, then you have to recalibrate and you measure from the ground to the rear lower control arm bolt in the front and enter that number............
How in the world are all of these Jeep people doing their tire swaps, lifts, leveling kits and more and still have working DASM???
They can't be working! I mean, changing the rake, lifting it, you have broken it and it won't work.

Mine works fine - with new glass. (well, it was until it got broken again)

Mine, and many others, have been working for months, even years, with new glass.
FCW and ACC worked fine with some massive interference......... not just the bug bodies themselves, but look how dusty the glass is. It did finally complain after some whopper bugs hit when we got back to Iowa so I cleaned that area off a little bit.

The specs for these windshields is crazy tight.

Even this quote is assuming the system is mounted to the glass -
>> With the introduction of ADAS into our automotive industry, there have been many changes to windshield specifications. They must have the proper pitch for camera mounting because 1 degree could make a difference and create a problem for the system to properly finish its calibration process after windshield replacement. There is also a need to make sure the camera view area has specified inclusions or a heated grid that does not restrict the view. A camera looking through a piece of glass that is not to specification could distort the images it was designed to see putting it into a "Kaleidoscope World".<<

Modern vehicle safety also isn't even playing the same sport as vehicles even 10-15 years ago let alone the stuff before that. A 5-star Volvo wagon from 2000 wouldn't even pass modern testing and that was considered the pinnacle of safety engineering.

Yeah accidents happened and people died, but all you need to look at is the fatality numbers over the past few decades to realize even the JL/JT is crazy safe compared to those that came before it.

Ever watch an old cops show from the 80s when they show accidents. Your average Japanese car or American economy car crumpled like a tin can.

Hell, my fiancée had a 2005 Kia Optima when I met her. That thing was so poorly engineered that when you jacked it up, the body flexed so much you couldn’t open the doors. No rust no accidents, just a poorly engineered, pile of shit like Korean cars were back then. She didn’t have that for very long before I helped her get another car. It was a POS all around.

Just trying to convince people that they don't have to throw extra money away just because the $15 an hour tech says it's in their handbook that you HAVE to re-calibrate if replacing the windshield. If the two aren't physically joined (which they're not as my folding and raising of windshield was meant to prove) and there is no direct impact to the windshield right in front of the sensor.

Yet when a Master Technician with the company that made the damned vehicle says it's a not needed procedure UNLESS the sensor was impacted everyone wants to disbelieve it.

$400 to put it in calibrate mode and drive it?????

LOL - that's hilarious. What a crock and people are falling for it.
