Challenger's Random Electrical Glitches Need Urgent Fix

Had similar symptoms on a 2011 Charger. Unusual warning signals, infotainment glitches, and inconsistent control module behavior pointed to a communication issue in the BUS system. The scan tool initially showed multiple codes, making it hard to pinpoint the exact problem. After thorough engine diagnostics at a specialized shop, they found corroded cable connections to the main control module. The connection degradation was causing intermittent communication failures across various vehicle systems. This is actually a serious issue that requires immediate attention. Poor connections in the BUS system can affect critical vehicle functions, not just convenience features. The warning light patterns you describe match classic symptoms of compromised network communication between control modules. The repair involved cleaning all connection points, replacing damaged cables, and updating the control module firmware. After fixing the cable connections, all systems returned to normal operation with no recurring warning signals. Would strongly recommend having a shop with experience in automotive network diagnostics examine the vehicle. These symptoms typically worsen over time and can lead to more extensive electrical system damage if left unaddressed.

Thanks for sharing that experience. I also struggled with bizarre electrical issues in my Challenger where the OBD-II scan showed multiple unusual codes. After trying three different mechanics, we finally discovered it was a failing battery causing voltage drops that messed with the control module communications. Mind sharing what the repair ended up costing you? Also curious if youve had any lingering issues since getting it fixed? My total repair including labor was around 850€ but I keep checking my malfunction indicator just to make sure everything stays normal.

The repair at the specialized shop came to 155€ which covered cleaning and replacing the faulty cable connections to the control module. Since fixing that BUS system communication issue, all those unusual electrical glitches and system failures have completely disappeared. The malfunction indicator has stayed off and the control module is working perfectly, no more warning lights or infotainment freezes. The scan tool readings are now consistently clean without those confusing multiple error codes we saw before. While your battery-related fix was more extensive and costly, both situations show how important it is to get proper engine diagnostics from shops that really understand these electrical systems. Having a stable connection to the control module is crucial for all vehicle systems to communicate properly. Glad you got your service required issues resolved as well. These electrical gremlins can be tricky to diagnose but usually have a clear fix once you find the root cause.

After dealing with those frustrating electrical problems, I finally got it all sorted out. Took my Challenger to a shop specializing in automotive electronics after the system failure warnings kept popping up. They ran comprehensive engine diagnostics and found the failing battery was causing voltage fluctuations that confused the control module. The repair set me back 850€ but it was worth every cent. No more unusual warning lights or OBD-II error codes. The infotainment system works perfectly now and all electrical systems are stable. Its been 3 months since the fix and I haven't seen a single warning light. Still find myself glancing at the dash occasionally just to make sure everything stays normal, but the car runs like new. Just glad I found the right shop that could properly diagnose the issue instead of wasting more time with mechanics who were just guessing at the problem.
