Common Causes of a Lexus RX 350 Seat Belt Warning Light
Several factors can trigger a persistent seat belt warning light in your Lexus RX 350. These include faulty seat belt buckles, wiring issues, a malfunctioning seat belt pretensioner, or problems with the seat weight sensor. Identifying the root cause is the first step toward effectively addressing the issue.
Faulty Seat Belt Buckle
One of the most common culprits is a faulty seat belt buckle. Over time, the buckle mechanism can wear out or become damaged, preventing it from registering that the seat belt is fastened. This can trigger the warning light even when the seat belt is clicked in.

Wiring issues can also contribute to a persistent seat belt warning light. A frayed or damaged wire in the seat belt system can disrupt the signal sent to the vehicle’s computer, causing it to believe that the seat belt is unfastened.
Malfunctioning Seat Belt Pretensioner
The seat belt pretensioner is a safety device that tightens the seat belt in the event of a collision. If the pretensioner malfunctions, it can trigger the seat belt warning light. This is a critical safety issue that requires immediate attention.
