I had a 2019 Nissan XD Cummins purchased in February 2019. Everything was fine until running down the road at 70 mph a warning to Stop truck now. Particulate filter issues at 6000 miles. I called dealer. He said to get truck towed which I did. They kept truck 2 weeks. They said truck needed a regen. I started driving home 64 miles away. 20 miles later same warning on particulate filter. Called dealer they just needs regen. I drove truck 120 miles and regened twice. Dealer didn’t know what to do and said just drive it. 8800 miles and several regens I called dealer about new warning on particulate filter. They said just drive it over here. About 10 miles from dealer went to limp mode. 1 1/2 months later Nissan Engineer still hadn’t showed up. Finally 2 months later dealer said the Cummins truck had major issues. They replaced turbo and some other parts. It still had issues Engineering couldn’t fix. Truck went to market I was told. I traded for Gas XD in September after waiting a month and a half on no show engineers. The gas XD has issues with front end after 2100 miles. That’s another story. I like the XD ride. and all the features but I’m beginning to wonder about these trucks.
