There are 5 owner-reported fuel system complaints for the 2018 Ram 2500in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Reverse camera started to act up causing my camera to not be available while I am in reverse, this has also coincided with an error message stating "Service Electronic Throttle Control". My truck has experienced slow acceleration and the maximum speed is only 60 mph. My stability control warning light is also on with the flashing "lightning bolt" and I can no longer use my cruise control. The audible crash prevention warning when I reverse also no longer works.
There is a chronic problem with most Ram trucks, this issue isn't just related to one model of Ram trucks. The problem is when you go to fill-up your tank with gas, the fill neck continues to back up, which requires skill & a lot of patients just to fill your tank. And, this is also a major safety concern due to the high likely hood of an overflow of fuel & possible fire & explosion situation. After much research & being a professional aircraft mechanic, what I found to be the problem in most all cases is a defective ( FUEL TANK ROLLOVER VALVE). I took my truck to the dealer when it was under warranty & just a few a couple of months old for this exact problem. And, they told me there was nothing wrong? I now know the reason they told me this is because this fuel tank rollover valve is an integral part of the fuel tank & is expensive to change. With this extremely long history of failures with the (FUEL TANK ROLLOVER VALVE), I am totally convinced this should be a Recall item!
Truck def system error derates vehicle speed to 5mph in 85 miles. This is unacceptable as no dealerships are open on weekends or in the middle of nowhere. This EPA rule will get folks killed as folks driving 5mph on freeway towing a big trailer will get run into real quick. Vehicle should NOT cause you to slow to 5mph if a pollution control device has issues. Please investigate.
THE FUEL TAKE DOES NOT ALLOW PRESSURE TO RELEASE CAUSING A ENGINE LIGHT AND REFILLING PROBLEMS. I CAN GET ABOUT HALF A GALLON IN AT THE PUMPS AT A TIME. THIS PROBLEM OCCURRED RANDOMLY ABOUT 8 MONTHS AFTER PURCHASE OF THE NEW TRUCK. THE DEALER HAS HAD THE VEHICLE IN 4 TIMES NOW. 1. DIAGNOSTIC, COMPUTER AND ENGINE LIGHT RESET. 2. DIAGNOSTIC, ENGINE LIGHT AND REFILL PIPE REPLACEMENT. 3. DIAGNOSTIC, ENGINE LIGHT AND FULL TANK REPLACEMENT. 4. DIAGNOSTIC, ENGINE LIGHT AND NO SOLUTION. THE VEHICLE WAS TESTED AT DIFFERENT GAS STATION PUMPS ALL PRODUCING THE SAME RESULT. FAILURE TO FILL CONTINUOUSLY AND REPEAT ENGINE LIGHT.
