Chrysler 300 Battery & Sensor Woes Need Expert Fix

Had similar symptoms on a 2014 Chrysler 200 diesel. The slow cranking and flickering lights pointed to a low voltage issue. After proper battery testing, the problem was traced to a faulty battery sensor that was sending incorrect readings to the power management system. The repair involved: Full diagnostic scan of the electrical system, Battery load test to verify battery condition, Replacement of the battery sensor unit, System recalibration after installation The battery sensor malfunction was causing the car to incorrectly read battery charge levels, leading to incomplete charging cycles. This is a known issue that can damage the battery over time if left unchecked. The repair was straightforward but required specific diagnostic equipment to properly test and calibrate the new sensor. The battery itself was actually in good condition once the sensor was replaced. This is a serious issue that needs proper attention since a malfunctioning battery sensor can lead to: Unreliable starting, Possible battery damage, Risk of getting stranded, Electrical system instability Recommend getting it checked at a shop with proper diagnostic capabilities for Chrysler vehicles. The symptoms match exactly what I experienced before the repair.

Yep, had that exact same issue with my Chrysler 300. The battery testing revealed a faulty sensor just like yours. The car runs perfectly now after the fix, and regular battery maintenance keeps the electrical system stable. Would be curious to know how much you ended up paying for the complete repair. Also, have you noticed any other electrical quirks since getting it fixed? In my case, the power windows started acting up a few weeks later, but that turned out to be unrelated.

Had the repair done last week, the battery sensor replacement came to 315€ total, including the comprehensive vehicle diagnostics and system calibration. The battery voltage readings are now accurate and stable. Really happy with how the car performs after the fix. No electrical issues since then, all systems working perfectly with correct battery charge readings. The flickering lights and slow cranking completely disappeared once the faulty sensor was replaced. Regular battery testing shows everything is working as it should. Interesting about your power windows, definitely sounds unrelated since the battery sensor only affects the charging system and battery maintenance monitoring. The repair shop confirmed the battery itself was in good condition, just like in your case. The problem was purely the sensor sending bad data to the car's computer. For anyone else reading this thread, if you notice similar symptoms, get the battery sensor checked right away. The repair cost is worth it to prevent potential damage to other electrical components.

Thanks for getting back to me about your repair experience. Finally got my car fixed last week at a local specialist shop that really knew their stuff. The mechanic actually took the time to show me the faulty battery sensor and explain the whole diagnostic process, which was refreshing after my previous bad experiences. The final bill came to 295€ including full vehicle diagnostics and parts. They also did a thorough battery charge test to confirm the battery itself was still good. What a relief to have the car starting properly again, no more slow cranking or dim lights! The peace of mind was worth every cent. The shop even gave me some tips about monitoring battery voltage and keeping an eye out for any warning signs in the future. After a week of driving, everything is working perfectly. Really glad I got this sorted before winter hits. Looking back, I probably should have addressed those battery issues sooner, but at least now I know what to watch for. Nothing better than having a car that starts reliably every time.
