One problem related to coolant leaking has been reported for the 1999 Dodge Neon. The most recently reported issues are listed below.
Head gasket failed. Checked repair costs at 7 different mechanics, including Dodge dealer ($650-$1000); all seemed very familiar with the problem. Many didn't even have to look up the price to repair, they knew it off hand. 4 different family/friends also have had same problem. Was told by dealer to watch for oil leaking into coolant, as this is another common problem, with more dire consequences. Why is this not a recall issue?.
