NHTSA Complaint #11633183 — 2018 INFINITI QX60

Check engine light came on, poor idling and start up. Infiniti replaced pvc hose that was cracked, electical seat warmer issue was fixed, dvd electrical issue was denied under the claim warranty, and some sensors were replaced due to codes of lean fuel, and the technician noticed a ticking noise. The dealership told us to pick the car up, drive it and put more miles on it and bring it back in to file another claim for the ticking sound. Returned to file new claim and was told the engine needed to be replaced or timing chain should be replaced due to sludge in the engine even with proper maintenance [records submitted to dealership for warranty claim which was denied]. Passanger seat warmer had also gone out since our last visit, so they're fixing that electrical issue as well. [We were denied for driver side electical window repairs, as they said components were "only loose"]. We purchased the Elite Protection Plan that should have covered all issues but they are denying the claim. Main concern is the engine as there are multiple forums and social media groups that are complaining of the engine sludge issue on new or certified Infiniti or Nissan vehicles with the same engines. Most owners are providing service/maintenance records and still being denied engine repair or replacement under warranty. These engines need to be recalled and consumers need to be compensated for their time and repairs.
