“I was informed in January of 2020 of a safety recall pertaining to the low pressure fuel pump in my Lexus NX300. I learned of the recall via CarFax rather than through Lexus. As I continued to drive and service the Lexus NX300, I received conflicting information from Lexus about whether or not my vehicle was impacted by the recall. Regardless, Lexus informed me that there was no remedy for the defect. In July of 2021 (at least 18 months after the defect was identified) I finally received notice from Lexus that a remedy is available. Lexus clearly knew of the defect prior to issuing the recall, but waited several months before even directly notifying me of the recall, allowing me to drive a vehicle they had already deemed unsafe for months. It is absurd that a manufacturer would allow unsafe vehicles on the road, jeopardizing human lives, while the manufacturer took their time to find a solution. In the meantime, they released new/refreshed vehicle models. This is a clear example of a car manufacturer placing profits over safety and should be addressed. For the record, I no longer own the vehicle. I decided to get rid of it when I lost faith that Lexus would ever resolve the issue.”

“I have attempted informing Lexus of this situation. To my knowledge, they have not pursued the case. On October 31, 2023, we brought our NX300 [XXX] ) in at 44,806 miles. The left parking brake actuator was inoperative (also rendering the cruise control inoperative). To get to the dealership from Ormond Beach, I removed the appropriate fuses to avoid any undesired operation from the unit. I was hoping any problems would be covered by warranty—it had under 50,000 miles. The Basic Warranty had expired. The Powertrain Warranty was still in effect. Strangely, brakes are not listed in either warranty. This was definitely NOT a wear and tear item. After inspection by Lexus mechanic, the failed actuator would not and could not be covered by warranty. The ‘out-the-door’ cost was $1371.43 (RO# [XXX]). I asked for the old part, which I still have. There is an extreme manufacturing defect I found. Lexus charged $997.63 for the part. The same EXACT part is available online for $37.70---OEM is $189.00. I understand price markup is required for any business, but over 500% may be a bit excessive. I was truly shocked by what I had found within the sealed actuator. The why and…”
