What years to avoid on a Lexus LS430?
While the Lexus LS 430 is generally a reliable car, the 2004-2006 model years have specific recalls, and all model years from 2001-2006 may have transmission issues, according to CarParts.com. Some 2004-2006 models were recalled for faulty airbag inflators, and transmission problems like hesitation or jerking at lower speeds are more common in this generation, notes CarParts.com.

- 2001-2006 (General Transmission Issues): These models can experience issues with transmission hesitation or rough shifting, especially at lower speeds. A faulty downshift solenoid can be a cause, or a software update may be needed.
- 2004-2006 (Airbag Recall): These specific years had a recall for airbag inflators in the curtain side and knee airbags. Lexus has offered to replace them at no cost.
Things to consider
- Airbags: Even though there was a recall, it's important to confirm that any potential purchase has had the airbag issue addressed.
- Transmission: Check for any signs of poor shifting performance. A transmission replacement or software update might be necessary to fix this problem.
- Maintenance: The reliability of any used car depends heavily on its maintenance history. A low-mileage, well-maintained 2001-2003 model is likely a better choice than a poorly kept 2004-2006 model.
