I was driving on 64 and at a sudden my 2018 NX 300 stopped accelerating and engine was stalled. I was lucky that the highway was not busy, so I was able to park it on the shoulder of HWY and later towed it to my home. The car was not drivable anymore as engine was keep shutting down with the warning and engine lights. The code on the screen was P0087 - Fuel Rail/System Pressure - Too Low. It seems that the fuel pump mall function. I research online and noticed, that others also reported the same issue related to Fuel pump failure on this model. Also, on further research, I found that Lexus recalled this model along with other models for the same issue. But when I check my VIN then it shows that my VIN has no recall related to Fuel Pump mall function. Not sure why my VIN is not included in the recall even though this model and year has a recall for this issue.

HVAC Evaporator Drain Hose keeps getting clogged resulting in the overflow of water into the cabin driver side floor. When using the AC or Defroster this could be a quart of water or more which can result in mold/mildew on carpet and pad. Lexus wants $6000 to repair and replace (they will not repair with out replacing all of the carpet and pad). This is a known issue and Lexus have even issued a "fix" AT THE CONSUMER EXPENSE. https://static.nhtsa.gov/odi/tsbs/20...31864-9999.pdf If a recall were issued for the recommended part (ARINIX Tip) to be installed then the consumer could save thousands of dollars for the replacing of carpet and pad plus labor.
