I have a 2012 Dodge Journey SE, purchased used and after a month or so started having what appeared to be battery issues. Go to start car in the morning and nothing, charge the battery and everything is OK, checked whether charging while running OK and after going through this procedure several times noticed that the dash lights were not turning off. Read all the complaints about these lemons and on checking with the dealer found that they knew squat and kept saying it's the battery. So I took up the challenge, bought a new higher cranking battery and yes you guessed it same results. My grandson has the old battery and it's still working fine in his Kia. I started to monitor the dash light problem and determined that if I was alone in the car the lights would shut off after about 8 to 10 seconds, however when more than one person exits the car the lights stay on, and they also stay on when I open a second door before the lights go off. My new rule was "first door opened has to be last door closed" however that doesn't always work. It's a pain standing beside the car to make sure the lights go off ! By the way if they stay on I have to turn the car back on without starting it, wait until everything clicks in, warning lights, radio etc. then turn it off and get out and usually the lights will then turn off.
Back to the dealer who then ran a scan for $100.00 and determined that the instrument cluster is receiving false readings from the BCM which they would replace for $600.00. Given that many others have been hosed on repairs I am hesitant to get this done, can't they simply flash the BCM to fix this? Can I buy and install a used unit and sell this thing?
