Common Lexus RX 350 Repair Points

Transmission

The RX 350 uses a robust 6- or 8-speed automatic transmission depending on generation. While failures are less common than on some competitors, when they do occur, the luxury repair profile means costs are substantial. Transmission rebuild or replacement runs $3,500 to $6,500 — significantly more than comparable mainstream SUV repairs.

RepairPal and Lexus owner community data show that while the RX 350's overall repair frequency is below average for luxury SUVs, the cost per repair event is significantly higher than mainstream vehicles — making extended warranty coverage especially valuable on a cost-per-dollar basis.

A/C Compressor

A/C compressor failure is the most commonly reported expensive repair on the RX 350 — particularly on 3rd generation models (2010–2015). Replacement costs $1,200 to $2,500 reflecting premium compressor parts and dealer labor rates.

Fuel Injectors

Direct-injection fuel injectors on the RX 350's V6 can develop carbon buildup and eventually fail, particularly after 100,000 miles. Full injector replacement costs $800 to $1,800.

Power Steering and Cooling

Power steering pump issues and water pump failures are periodic concerns on higher-mileage RX 350s. Power steering pump replacement costs $700–$1,400 and water pump replacement runs $600–$1,100.
