2019 Nissan Nv

While driving the vehicle on the highway it suddenly it made a ticking noise and would not go more than 40 miles per hour. We limped into a repair shop. The upper catalyst crumbled and was sucked into the lower catalyst causing total failure. The vehicle was completely incapacitated on the roadway. This is all available for inspection. The vehicle has less than 7,000 miles on it when it failed. It left a group stranded and had to be pushed off the road. The problem was confirmed at a dealership with a quoted price of $26,000 to replace the entire long block. There were no warnings or lights before it happened, but the check engine light came on right when the vehicle slowed down to 40. we were on the highway and the fact that the vehicle couldn't go to speed made it very dangerous.

I was driving 75MPH down the interstate when out of nowhere my engine started acting funny. It started to slow down and then the check engine light came on. As we were exiting the engine started stuttering. We were able to get it to a gas station. It was towed to a mechanic where they found that there were multiple cylinder misfires. They also found a hole in the cylinder head/valve cover. With the vehicle slowing down on its own it could've caused a wreck. The stuttering on the offramp put my family at risk of being hit while trying to turn onto the street for the gas station. I do not believe the problem has been reproduced since it has been towed since then. We are taking care to not drive or cause any further damage to the vehicle. The check engine light turned on as the vehicle began to slow down. Before that it was sounding off, for a mile or two, but no lights were on. We were already planning on stopping to check it out when the engine failed. We have yet to be able to get it repaired, as the extended warranty won't cover and we can't afford a new engine.
