First off, I am not sure yet of the name of any law firm that has handled any class action suit. Second, I just reached out to Ram Care on Saturday August 1... [we will see]. My surging, shifting issues are noticeable at low elevations, with no load, at about 5th gear. The higher in elevation you travel, the more severe the surging and shifting gets! So I sent it to the dealer, and they performed a relearn? Why,,, They stated we don't know what to do, please call Ram Cares!!! Thats really helpful!. I contacted a diesel mechanic who has specialized in building cummins, and racing dodge trucks. So I drove 330 miles to Lubbock. Since Lubbock is so flat, it was difficult for him to replicate the issue, until I had him slow down, and accelerate at a consistent somewhat slow rate up a soft overpass. Well yep, there it is. We looked at the computer that was plugged into the truck, and the fuel pressure firing was all over the map! 14-41 I believe. Also I learned that Ram decided to use the CP4 fuel pump in the 2019 diesel trucks... Yep a supposed remake of the detrimental cp4 pump that GM, FORD, and others were sued over. I then took the truck to Andrews, Benny Boyd Ram diesel mechanic, who verified that there are issues with the Aisin transmission software, and the new CP4 fuel pump, and Ram doesn't Know what the fix is! I also have found out that All these diesel vehicles are advertised, and sold as a particular tool, capable of doing a job! More than the competitor, So we buy the overpriced item in one condition, then they tell you there is a recall that has to be addressed, and you end up with a different product, far less than what you purchased. My fuel mileage has dropped by 2-4 mpg since I have owned it. Dropping every time they touch it! The idea that they can sell an item in one condition, and then once you pay for it, change it to fit the governments emissions standards is illegal. Bait and switch, false advertising, I am looking at an attorney if this doesn't get resolved soon, and honestly!
