I'm with sunset, take it back to the dealer.

Years ago I had a new Mercury Topaz. Drove from Seattle to San Fran. On the way back it started to lose power and finally could get no more than 40mph out of it. Took it to the dealer the next day and they said the cat converter was clogged and I must have put leaded gas in it (some leaded gas was still available back then). I told them that was impossible as I was the only one filling the tank and since it was still under the 50,000 emission warranty they had to replace it. Got it back and it ran fine and even passed the emission tests for several years. Then one year it wouldn't pass so I took it to another Ford dealer, they checked it and said someone had gutted the Cat converter. Took it back to original L/M dealer where it was purchased and told them to replace the gutted Cat or I was going to the State AG. They replaced it that day and the next day it passed with flying colors.

I now own a 2006 Charger RT Hemi, Bought there $399 lifetime oil service deal, We keep our vehicles a very long time, still driving a 95 Dakota and a 96 Intrepid, and have been changing the oil and filter every 3000 mi. or 3 months whichever comes first as per the $399 deal for 3+ years now. This last change I was informed the trans needed a service for $400 so I asked why as the owners manual calls for a service after 60,000 mi. Was told the fluid was low. As some of you may know Chrysler products no longer have a trans dip stick and the trans is no longer serviceable buy the owner. Went to the Charger forum on the web and found out the trans in the Charger is a mercedes so all that is needed is to get a Mercedes dip stick. Did that, checked the fluid and sure enough it was down almost a qt. Now it was fine for the last change and we had put less than 500 mi. on it since the last change and it doesn't leak a drop anywhere. Anyway I filled it myself and am interested to see what they find wrong when I take it in next time and I am sure it didn't leak nearly a qt. in less than 500 mi. Long story made just a bit longer, I don't trust dealers. The dodge dealer figured out that in my case that my $399 deal for them is going to be a loser for them and are trying to recoup their loss. Sorry for the rant.

Jack.
