Ran a diagnostic and I have a bunch of codes that come up: C2100 battery voltage low C2101 battery voltage high C2115 dynamics sensor supply voltage high C0562 system voltage low C121c torque request signal denied Any thoughts?

Both the alternator and battery were purchased at A Napa auto parts store earlier this year. And the voltage was tested mostly at the terminals on top where te cable from the battery branches off to the fuse box and starter/alternator (where you attach booster cables). I'll try testing the voltage again here today and update you. Thanks.

Thanks for the reply. To answer your question no there are no aftermarket devices installed. It does have a remote start but I believe it is OEM. I should mention that we did put a voltmeter on it while it was running and the voltage did seem to be in the range to charge the battery, well over 14 or 14.5 volts and it seemed to respond to an increase in engine rpm to some degree. As well, the batteries I've had connected to the vehicle do seem to hold a charge somewhat, but it doesn't seem to be a charge that's a result of being charged by the alternator, but rather if it were left from being hooked up to a charger. And in the instances where the engine died while the vehicle was running, attempting to start it immediately afterward showed there was no charge left in the battery. Another possibly unrelated thing i might mention is that I noticed a couple of times while the engine was off there was a relay clicking wildly and loudly for probably a minute at least when no power should have been drawing. I thought this might be normal when a battery has a very low level of charge but in not really sure.

I have a 2009 Journey R/T with 3.6L V6 AWD and for a while have been experiencing battery drain whenever the vehicle is left for more than a few hours. After several unsuccessful attempts at finding out the cause for this, I decided to temporarily install a 500A switch to isolate the battery from the rest of the vehicle's electrical system, to prevent having to jumpstart the vehicle every morning. This has been effective in this regard for a while now, however, the other day while travelling on the highway the vehicle started experiencing a loss of power for a second or so, then power would be restored, and this would randomly repeat for the remainder of my trip. Then, upon my arrival at my destination city, when coming up to a stop sign and the engine idled down, the power loss occurred again only this time the engine died. When I attempted to start it immediately after this, I found there was no charge left in the battery whatsoever - no dash lights,no sound....couldn't even shift from park without using the manual release button. I then used a charged battery to boost the vehicle, and it fired up, but after continuing to drive a short distance, the same thing happened again, I then noticed the battery symbol for the charging system had appeared. Then the vehicle could only been driven with limited power and only without using any headlights for a short time (constantly requiring me to press the accelerator to prevent idling too low) before it would die again with the battery drained. I have checked all the connections, all the cables, swapped the battery for a different one, removed the battery and jumpered it directly to another running vehicle, all with the same result. It will fire up, and run for a short time, then the charging system symbol will light up, and the engine will die shortly thereafter. It will run for a while jumpered to another vehicle, but even during this time the warning light will still come on. I removed the alternator and had it tested - it passed all tests and I was told it was good. I should also mention that this alternator was purchased and installed just 8 or 9 months ago, and the battery was only purchased a month or two ago. The belts appears to be working properly and with the correct amount of tension, and as far as I can see all of the conncections are solid and free of corrosion, etc. I'm uncertain as to where I should go from here, and after being left stranded several hours from home for a few days now (everywhere being closed for Christmas) and the expense of hotel rooms, I don't wish to throw a bunch more money away for the dealership to try all the things I've already tried, with no guarantee of results. I am planning to run a diagnostic tomorrow to see if this yields any additional information as to the possible cause of the problem, but am hoping maybe another forum member could provide some insight if they have encountered a similar issue in the past. Thanks in advance for your assistance.
