Tiny Cable Damage Triggers Total Jeep Grand Wagoneer Interior Disassembly

The automotive industry loves touting its ever-increasing technological marvels. Rear-seat entertainment screens? Child’s play! But what happens when those marvels malfunction? In the tragicomedy that is modern car repair, a simple cable issue with a 2023 Jeep Grand Wagoneer’s entertainment system has apparently morphed into a symphony of disassembly.

According to a service technician, fixing a single cable requires stripping the interior down to its bare bones. It’s enough to make you wonder if Jeep secretly included a hidden “rearrange the entire car” minigame for bored passengers.

To be clear, the issue at hand reportedly popped up over 12.5 inches of damaged cable. This type of cable isn’t the kind one can simply cut out, splice, and walk away from. To fix it, the entire body harness has to come out and a new one must go back in. Of course, to access the body harness, just about everything has to come out. And we mean, everything.

That includes the seats, the interior trim, the carpet, and more. Photos from the ordeal show just how barren the SUV was mid-way through the fix. All that remains inside appears to be the lower climate control venting system, the dash, the steering wheel, and some of the pillar trim. The headliner had to come down twice apparently because of two crossed circuits.

According to the tech who posted about the job on Reddit, combined labor in Jeep’s system added up to 24.8 hours. The entire issue came from an open circuit in a low-voltage differential signaling cable “from the video routing module to the passenger display screen on the seat.”

If you’re not sure what any of that is, I just want you to imagine how the person who owns this in seven years will feel when they learn about it the hard way.

The tech reports that everything went back together just fine and that the owner reported “no complaints about squeaks, rattling or fitment.” That’s a feat all by itself even if no harness ended up replaced.

It took just over 14 real hours which is another major achievement. As a thank you, the customer evidently brought popsicles for the entire service team.
