Pacifica Hybrid Turn Signal & Speedometer Fault Alert

The symptoms match what happened on my 2021 Chrysler Grand Caravan Hybrid. The turn signal lamp started acting erratically, triggering multiple dashboard warnings. A thorough inspection revealed corroded terminals in the main signal lamp connector. The electrical fault originated from moisture penetration near the bulb housing. The repair involved cleaning the connector terminals, applying dielectric grease, and replacing the turn signal bulb socket. While this might seem minor, faulty connections can cascade into more serious electrical system issues if left unaddressed. The BCM (Body Control Module) stores these fault codes to prevent potential safety concerns with the signal lamp system. Based on the age and mileage of your Pacifica, checking the wiring connections should be the first step. A qualified shop needs to perform a complete diagnostic scan, as the stored error codes will point to the exact circuit causing the electrical fault. The turn signal issues often trace back to either the bulb replacement being needed or deteriorated wiring connections. These connector issues are fairly common on Chrysler hybrids from that generation. Having it properly diagnosed early prevents more extensive electrical repairs later.

Thanks for sharing those details about the turn signal repair. Did you remember the total cost of the bulb replacement and connector service? My Pacifica is acting similar now, especially with the fault codes, and I wonder if I should budget about the same. Also curious if you had any other electrical gremlins pop up since getting it fixed, these automotive lighting problems can sometimes come back.

Great news to share, I did have my turn signal issue completely resolved. The repair shop found a loose cable connection behind the signal lamp assembly, similar to what you are experiencing. The total came to 95€ for diagnoses and fixing the faulty wiring connection. It turned out much simpler than initially feared, no broken lens or complete signal lamp replacement needed. Since having the electrical fault fixed six months ago, the turn signal has worked flawlessly. No more dashboard warnings or error codes related to the automotive lighting system. The repair shop mentioned these connector issues are quite common, especially as the wiring harnesses age. Regular inspection of the bulb connections can prevent future problems. Getting it fixed promptly was definitely worth it to avoid more extensive electrical repairs down the line. Based on your similar symptoms, you might be looking at comparable repair costs, assuming its also just a connection issue rather than needing full signal lamp assembly replacement.

After reviewing everyone's input, I went ahead and took my Pacifica to a certified shop last week. The mechanic found corroded connectors in the flasher relay circuit plus a failing turn indicator bulb. Total repair came to 120€ including parts and labor. The signal lamp is working perfectly now and all error codes have cleared from the display. No more unusual electrical fault warnings either. The mechanic showed me the old corroded parts, it was pretty obvious why things were acting up. Quick word of advice for others: The shop mentioned these connector issues are pretty common as these cars age. Getting it checked early saved me from bigger problems later. Really glad I asked here first instead of putting up with those warning messages.
