RE: Gas tank capacity
My dealer has just told me the same thing Kardrob reported, but not until after I was told that it was nornmal operaton, then was told that that resetting the computer at each fueling would make it better (a nice trick, being able to improve normal operation!), then they changed the sending units under warranty. I bought my brand-new '05 in May of '06, and after that much time, I figured this problem had to be known, so I was shocked that Dodge didn't seem to know anything about it yet. I was even told that the field engineer had the same problem with his, but thought nothng about it.
To add to the confusion, everything about the problem points to the tank being able to hold only 20 gallons. In fact, when I had run the tank down to just over 1/8 on the gas gauge, the tech told the service writer tha the gauge must be right, because there were only 3 or 4 gallons left. Surely if there is a 4 to 7 gallon reserve (on top of the 2.5 to 3 gallons left, if calculating a 20-gallon tank), the tech wouldn't have misjudged it by that much. There's a lot of difference between 4 gallons and 10 gallons!
I am told that this is the same tank used in '04 and '06, so the problem has been around for some time without being resolved. If the '04s didn't have a probem, all they have to do is use the same software. If the'04s did have the problem, why has it taken so long to fix? I am a big Chrysler fan, and am very disappointed at the lack of knowledge over what has to be a well-known problem. I need the range that a known quantity of 27 gallons should give, but I am becoming more and more convinced that this is really a 20-gallon tank, which they don't want to have to replace on every unit in the field. If this isn't the case, the problem surely would have been resolved by now.
