Lexus RX 350
The 2GR-FKS is the latest evolution of the proven 3.5L V6 — dual injection keeps valves clean. Water pump and ignition coils are the only regular items. Significantly more reliable than turbocharged competition.
V6 RX perfected — the last generation before turbo-four
295 hp from the 3.5L V6 with dual injection — more power, cleaner intake valves. The AL20 is the most refined V6 RX ever built. Rain sensor issues on 2017 models are annoying but cheap. Infotainment runs on Lexus's remote-touch system which is universally criticized. Brake actuator noise on some units. A 2018+ model with the safety suite and no rain sensor complaints is the sweet spot.
Engine Weaknesses 3
The 2GR-FKS inherited the timing cover leak from the 2GR-FE. First and second production years (2016-2018) were worst affected — a production process issue, not a design flaw. Leaks typically appear by the first or second oil change. Later production years are largely free of this problem. Repair costs are extreme due to engine removal requirement.
Symptoms: Oil leak from front timing cover, oil drip on AC compressor, burning oil smell under hood
The 2GR-FKS shares the water pump weakness with the entire 2GR engine family. Premature failures documented as early as 30,000-50,000 miles. Internal design is improved over the 2GR-FE but longevity remains below Toyota standards. Replacement is moderately labor-intensive.
Symptoms: Coolant leak from water pump area, overheating warning, coolant loss, whining noise from pump
Some 2GR-FKS engines consume oil between changes. Toyota considers up to 1 quart per 1,200 miles within specification. Owners report consumption beginning as early as 30,000-60,000 miles. The owner's manual instructs to check and top off as needed. Not catastrophic but requires monitoring.
Symptoms: Oil level drops between changes, low oil level warning, need to add oil every 1,000-2,000 miles
Vehicle Weaknesses 5
Rain-sensing windshield wiper system malfunctions, particularly at night. Sensor triggers wipers inappropriately or fails to activate in rain. Primarily reported on 2017 models. Sensor replacement or recalibration typically resolves.
The Lexus Remote Touch interface (touchpad controller) is slow and unintuitive. Navigation input requires excessive concentration. This is a design limitation, not a defect — no fix available beyond replacement with aftermarket head unit.
Brake actuator produces squawk or knock noise when pressing or releasing the brake pedal. TSB L-SB-0005-21 addresses the issue via actuator bleed procedure. Present on both hybrid and non-hybrid models. Noise is cosmetic in most cases; full actuator failure is rare on the AL20.
Front struts develop clunking or hollow noise over uneven surfaces. Same pattern as the AL10. Strut mount and bearing replacement resolves.
Doors produce rattling noise at highway speed. Door seal adjustment or replacement resolves most cases. Minor quality issue for a luxury vehicle.
