2017 LEXUS GX 460

Typical onset: 60,000-120,000 mi

Symptoms: Burning 1+ quart of oil every 1,000-1,500 miles with no external leaks, Blue smoke on cold start or under load, Low oil warning light between changes, Carbon buildup on intake valves exacerbating the issue

Fix: Requires engine teardown to replace piston rings and hone cylinders; often done alongside valve cleaning. Real-world repair involves 18-24 hours labor. Some techs do short-block replacement if cylinder wear is significant. Toyota issued TSB for earlier years but 2017s still affected.

Estimated cost: $4,500-7,500

Typical onset: 80,000-140,000 mi

Symptoms: ATF puddle or drips under front-center of vehicle, Transmission running hotter than normal, Pink or red fluid visible on cooler lines or radiator area

Fix: Steel cooler lines rust where they connect to the radiator or run along the frame. Replacement involves dropping the skid plate and sometimes the exhaust. 3-4 hours labor plus fluid flush. OEM lines recommended over aftermarket.

Estimated cost: $600-1,100

Typical onset: 70,000-110,000 mi

Symptoms: Clunk or thud on 1-2 or 2-3 upshift, Vibration at idle in Drive, Visible cracking or separation of rubber on mount inspection

Fix: Rear trans mount fails from heat and age. Access requires raising transmission slightly. 2-2.5 hours labor. OEM mount costs more but lasts; aftermarket often fails again within 30k.

Estimated cost: $350-600

Typical onset: 90,000-130,000 mi

Symptoms: Check engine light with P0410, P0418, or P0419 codes, Grinding or whining noise on cold start for first 60-90 seconds, Pump may seize or bearings fail

Fix: Air injection pump (emissions system) locks up or stops functioning. Replacement is straightforward: remove skid plate, unbolt pump from passenger frame rail. 1.5-2 hours labor. Some owners delete system in non-emissions states.

Estimated cost: $650-950

Typical onset: 80,000-120,000 mi

Symptoms: Clunking over bumps or during braking, Wandering or vague steering feel, Uneven inner tire wear, Visible cracking in rubber bushings on lift

Fix: Front LCA bushings (especially rear position) deteriorate from weight and off-road use. Requires pressing out old bushings and installing new ones or replacing entire arms. 4-5 hours labor for both sides plus alignment.

Estimated cost: $800-1,400

Typical onset: 100,000-150,000 mi

Symptoms: High-pitched whine or grinding noise from front of engine, Battery light intermittent or steady, Voltage dropping below 13V at idle

Fix: Denso alternator bearings fail; sometimes diodes go first. Replacement is tight but doable: 2-3 hours labor. Reman alternators common but OEM lasts longer. Serp belt and tensioner often replaced at same time.

Estimated cost: $550-850
