Problem with '06 Commander please help
I am a new member and have joined in the hopes of pinpointing a problem that I just had tonight with my 2006 Commander. To tell you all a bit about it, it has the 5.7L and is fully loaded. It has 50,000 miles. No problems at all untill now.
Ok, now for the issue.
When I got off work tonight, I hopped into my jeep as usual and it started right up as usual. But as I was about to put it into reverse I noticed that none of my dash guages were functioning. The lights were all on, but none of the guages were functioning properly. The Engine indicator light was on, as were the ESP and BAS indicator lights.
That is only the beginning. Not knowing what the cause might be, I turned off the ignition and restarted the engine. Same thing. I thought, well, I'll try driving it a bit to see if there really is anything wrong with it. As I started driving, after the tranny shifted into second, what sounded like the transfer case,-started grinding as if I was trying to switch into 4WD low while moving. I immediately stopped and turned the engine off again.
I sat for about 5 minutes debating what my next move should be. I then started the engine again. The lights were all still on, but the guages again were not working. I attempted to switch into 4WD L just to see if the t case was working properly, and it shifted in and out just fine.
I again started home and this time, kept the speed under 20 mph and had no problems with the grinding noise again. However, as I was driving up a rather steep hill, it became obvious that the engine was only running on 4 cylinders. As if the MDS wasn't functioning properly. I became very cautious of anything else acting up, and didn't notice anything else for the rest of the drive home (about 2 miles)
When I got home, I thought to try using my spare key just to see if anything was different using it. Well, it started up just fine again and this time, the ESP and BAS lights went off, but the SES light remained on. With this revelation I drove the Jeep around my block, and everything seemed to be running just fine.
Guages worked, MDS worked fine, everythig worked as it should, but the SES light was still on. When I got back home, I disconnected the battery cables and connected them again, started up the engine and voila! Everything working as it should. No service lights on, problem solved.
I then proceeded to drive around for another 10 miles with no problems what so ever! So my question is this:
What the heck happened!?
I thought that maybe when I first started it there may have been a voltage spike from the alternator, but am not sure if symptomology matches up. With the engine idleing and all electrical devices on, voltage at the battery is 14.10 volts with some fluctuation. No major spikes etc...
I really would appreciate some input because I love my jeep, but that one incident was enough to make me paranoid now.
Please give thoughts,
