🛠️ Common Issues with the 2016-2022 Lexus RX Series

The 2016-2022 Lexus RX series includes several models such as RX 350, RX 350L, RX 300, and RX 200t. Known for its luxury, reliability, and smooth ride, the RX lineup remains one of the best-selling luxury SUVs in its class. The RX series competes in the mid-size luxury SUV segment and provides modern safety tech, a comfortable interior, and strong resale value. Owners reported that the worst models are 2005 RX 330, and 2004 RX 330. However, like all vehicles, it has experienced certain electrical and mechanical issues, as well as recalls and technical service bulletins (TSBs).

Common Electrical Issues:

  1. Door Lock Actuator Failure: Owners have reported failures in the door locking mechanism, necessitating manual locking and unlocking. The solution typically involves replacing the faulty actuator.

     

  2. Electronic Key Malfunction: Some 2022 RX 350 owners have experienced intermittent failures with the electronic key system, even after battery replacements.

  1. Fuel Pump Failure: Multiple models, including certain 2017-2020 RX 350 and 2018-2020 RX 350L vehicles, were recalled due to potential low-pressure fuel pump failures, which could lead to engine stalling.

     

  2. Brake Booster Vacuum Pump: The 2017 RX 350 was recalled because an improperly machined oil galley in the brake booster vacuum pump assembly could result in a sudden loss of brake assist.
