NHTSA Complaint #11681143 — 2017 NISSAN TITAN

V8 endurance engine has a known defect with scaring of cylinder 7 causing knocking in the engines and engines replacements. I purchased this Titan brand new in 2017. It required a brand new engine at 18,000 miles that was covered by the warranty. That engine developed another knock that required another engine replacement at 89,000 miles. Initially Nissan refused to cover as the truck was more than 5 years old even though the miles were well below 100,000 manufacturer warranty. I have found that these are bad engines that dealership is continue to install in these trucks even knowing that it could develop another knock. Other engine manufacturers refused to work on these engines due to this known defect. Nissan has thus far refused to recall this engine. The replacement cost is $18,000 without warranty.
