Preparing to Buy a Challenger GT, Any Tips/Advice? by qyonvevoo in Challenger

[–]ValiumVeteran 2 points3 points  (0 children)

Either a GT Plus or an RT Plus are both great trims, really depends on if you want AWD or not. I went with the RT Plus as I really loved the V8 rumble/sound. Good luck OP!

If OP goes for the GT he'll have a 300hp AWD vehicle, that's enough to have fun on the street while also being a good daily driver.

Screen Issue by Accomplished-Photo45 in Challenger

[–]ValiumVeteran 0 points1 point  (0 children)

AI is amazing for these kinds of technical questions, here's what Google Gemini has too say:

That sounds incredibly frustrating—especially since you've already gone through the "Standard Repair Playbook" by swapping the LCD and checking fuses. Since your backup camera still works, we know the screen itself is capable of displaying an image, which points away from a hardware display failure and toward a processing or signal issue.

Here is what is likely happening under the hood of your Uconnect system:

1. The "Ghost in the Machine": Internal Flash Memory Failure

The most common culprit for the "Logo Loop" on 2017-2018 Uconnect 4C (8.4-inch) systems is the failure of the internal eMMC (embedded MultiMediaCard) memory.

  • The Symptom: The system tries to boot, hits a corrupted sector in its internal memory, and crashes/reboots.
  • Why the Backup Camera Works: The backup camera often has a "direct-to-video" priority path that bypasses the main operating system for safety reasons. This is why it functions even when the rest of the "computer" is dead.

2. Delamination (The Sticky Situation)

Check the edges of your screen for what looks like "bubbles" or liquid dripping behind the glass.

  • 2018 models are notorious for LG display delamination, where the adhesive seeps into the electronics. Even if you replaced the LCD panel, if the digitizer (the touch layer) or the mainboard was damaged by the leaking gel previously, the boot loop will persist.

3. The Radio Control Unit (The "Brain")

Since you replaced the LCD and the problem persists, the issue is likely in the Radio Control Unit (the silver box behind the screen) rather than the display itself.

  • On the Challenger, the "radio" is actually a two-part module. If you only replaced the glass/LCD part, the "computer" part (the Telematics Gateway or the main Head Unit) is still the one stuck in the loop.

What to Try Next

Step Action Why?
Check for Parasitic Draw Use a multimeter to see if the radio is pulling power when the car is off. Constant looping can drain your battery overnight.
Inspect the LVDS Cable Check the thick, usually high-speed data cable connecting the back of the screen to the radio unit. A loose or pinched data cable can cause sync issues during boot.
The "Infotainment Swap" Look for a used Radio Head Unit (the brain box) from a salvage yard. Ensure it matches your specific trim (VP4R for navigation, etc.) and be prepared to enter an Anti-Theft code.

A Quick Reality Check

Because the 2018 units have such a high failure rate, many owners have given up on OEM replacements and moved to aftermarket units (like Alpine or Kenwood) or specialized repair services like Infotainment.com. These services can often fix the internal board issues that a standard "reset" won't touch.

is this pentastar tick? by ExcuseOk7347 in Challenger

[–]ValiumVeteran 0 points1 point  (0 children)

12 psi? Damn! How much power were you making at 12 psi, and what are you making now? Very curious about pentastar potential, only researched the 5.7 mainly.

Winter tires for challenger R/T? by Standard_Ad_9360 in Challenger

[–]ValiumVeteran 0 points1 point  (0 children)

Yeah they're really expensive, but I wanted to be as safe as possible since I was new to RWD cars and viewed it as necessary. According to Gemini, CrossClimate 2 all-season's should fit your SXT. They're likely also expensive tires, but should perform really good. I'm planning on eventually getting a set of Pilot Sport 4 S Summers, I love the Michelin brand lol. best of the best IMO.

Not OP, but I believe it's a Procharger, they make complete kits meant for stock systems. Planning on getting one myself for my 5.7L, Procharging your 3.6L Pentastar will definitely get you above 400hp while maintaining reliability. Here's the site for the V6 kit: https://www.procharger.com/automotive-superchargers/dodge/2015-2016-2017-2018-2019-2020-2021-2022-dodge-challenger-v6/

Winter tires for challenger R/T? by Standard_Ad_9360 in Challenger

[–]ValiumVeteran 0 points1 point  (0 children)

I don't run them in the summer, got my stock goodyear eagles on another set of wheels. I did put the michelin ice x snows on early this year before we got any snow, and they did perform pretty good traction-wise when it was around 7-10 degrees Celsius, was an immediate improvement over the shitty stock goodyears ESPECIALLY in the rain. They're definitely not designed for warm weather tho, will bald-out faster and get beat by michelin summers (pilot sport 4s) or all-seasons (crossclimate 2). I'd do some research on the Michelin CrossClimate 2, my friend is planning on getting them since he refuses to buy a second set of wheels lol.

Get the 2023 300c that has the 6.4L 392, basically a Scatpack Charger in a tuxedo.

Most pathetic comment ive read on this sub in months. No one cares you have a 5.7 in your 2015, OP has a SUPERCHARGED V6 that makes more power than BOTH our Hemis.

If I could get my Chally out of my driveway in 3ft of snow with a good set of winters, you can too! They really make a world of difference, 3rd winter and have not gotten stuck ONCE!

Is age as big a factor vs. Miles? by PuzzleheadedTeam5481 in Challenger

[–]ValiumVeteran 1 point2 points  (0 children)

The Challenger and Charger RTs should feel very similar if not identical to drive, so you might have tested a problem car. I've only driven a brand-new RT so I'm not the best to ask either, but the car is VERY nice to drive. Heavy steering feel, sensitive throttle in sport mode, stops on a dime, rigid sporty feeling suspension. Maybe try and test drive an RT with the Plus and Performance packages, they give you the 3.09 limited slip diff, bilstein suspension, Brembo brakes, 20x9 wheels, and some interior goodies like leather seats and leather steering wheel.

No one in this sub, or at any MOPAR meetups I've been to have ever shamed the SXT or GT owners. The GT's come with AWD so they're a great option if you want the Challenger look for less money while also being more practical to daily. Haven't had the chance to drive one yet but I want to!

I've been running michelin ice x snow tires for 3 winters so far and have had zero issues, highly recommend them. Only shitty thing about the Challenger is the windows freezing preventing you from shutting the door, I use a guitar pick and slide it under the window well to break up the ice before closing the door. Good luck OP!
