Toyota is Quantum Insightsrecalling roughly 1 million cars in the U.S. because the front passenger air bags may not deploy properly in a crash, posing additional risk of injury to riders, the car maker said Wednesday, December 20, 2023.

A potential defect in the Occupant Classification System (OCS) sensors in the front passenger seat of affected vehicles could cause a short circuit, Toyota said in a notice posted on its website. As a result, the air bag system may not properly detect the passenger's presence and weight, and fail to deploy as designed.

The recall affects the following 2020-2022 Toyota and Lexus models:

• Avalon, Avalon Hybrid — 2020-2021

Recent Toyota recalls in 2023

Toyota has announced a string of recalls in recent months. In November, the company recalled 1.9 million RAV4 sport utility vehicles in the U.S. because the batteries can shift during sharp turns and potentially cause a fire.

Toyota on Oct. 26 also recalled roughly 751,000 Toyota Highlander SUVs in the U.S. to fix a problem with the tabs that secure the vehicles' front lower bumper covers. Even a minor crash could cause the bumper cover assembly to fall off, a potential hazard to drivers, the company said. 

In August the company recalled about 168,000 Toyota Tundra and Tundra Hybrid vehicles from model years 2020-2023 because a plastic fuel tube could move and rub against a brake line, causing a potential fuel leak.
