And now a class-action lawsuit has been filed for those who bought 2016-2019 Nissan Titan diesel trucks equipped with Cummins 5-liter engines. The 5.0-liter Cummins turbodiesel V-8 packed a punch with 555 pound-feet of torque and a max towing capacity of 12,830 pounds. Let’s take a look at the current lawsuit affecting these trucks. ### **Fuel system contamination** The first part of the lawsuit surrounds the confusing location of the diesel exhaust fluid filler tubes. The technical service bulletin (TSB) for the impacted trucks reads: “CAUTION: Putting Diesel Exhaust Fluid (DEF) into the diesel fuel system will contaminate the entire system causing permanent damage to system components. DEF contamination requires replacement of the complete diesel fuel system.” According to the [carcomplaints.com report](): Nissan dealers were reminded of the damage caused by contaminating the diesel fuel, “IMPORTANT: Diesel fuel contaminated with DEF will damage the complete diesel fuel system and cause many symptoms, including but not limited to the following:” - Crank no start - Long crank or hard to start - Rough idle - Low power warning - Fuel gauge inoperable or erratic gauge operation - Noise from the stage one fuel pump If you see any of these codes, it’s indicative of a problem related to this TSB: - P008A-00 LOW FUEL PRESSURE CONTROL SYSTEM - P00C6-00 FUEL RAIL PRESSURE - P0087 FRP CONTROL SYSTEM - P0463 FUEL LEVEL SENSOR - P2269-00 WATER IN FUEL CONDITION Lastly, the bulletin informed dealers that an owner will be responsible if they make the mistake of adding diesel exhaust fluid to the diesel fuel tank. ### **Nissan Titan diesel exhaust fumes** In a separate issue, the class-action lawsuit claims there were diesel exhaust fumes inside the truck’s cabin and a Nissan dealer couldn’t find anything wrong to cause this. Lawyers representing plaintiffs in this class-action lawsuit make some pretty bold accusations including: “Because of Nissan’s “misplacement” of the filler tube, Titan truck owners and lessees allegedly overpaid for their trucks, had to make repeated visits to dealerships, had to pay for damage to the fuel systems, and now the trucks allegedly have decreased values.” Additionally, the plaintiff says Nissan has refused to recall the Titan trucks to prevent customers from making mistakes when adding diesel exhaust fluid. And the automaker has also refused to recall the trucks to repair the “exhaust and/or HVAC systems which allow exhaust fumes to enter and accumulate in the passenger cabin,” according to the firm behind the class-action lawsuit. ### **The bottom line on Nissan Titan diesel truck issue** Diesel exhaust fluid (DEF) is always a complicated part of any diesel vehicle. Other automakers have had issues related to DEF, but this one with Nissan seems to have more legs to it. It seemed that the Cummins name and reputation would also boost the Titan’s reputation, but the pairing went poorly and didn’t have the end result Nissan would have wanted. In fact, the automaker is no longer going to offer the [Titan for sale in Canada](), which has us wondering if its days are numbered in the U.S. as well.
