Vehicle Specs & Maintenance Data
The 2019 Lexus Rc maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Lexus Rc.
For oil changes, the 2019 Lexus Rc takes 0W-20 Full Synthetic motor oil with a capacity of 4.4 quarts. Brake fluid type is DOT 3, the recommended coolant is Pink Long Life Coolant (OAT), and transmission fluid is ATF WS. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Lexus Rc, torque the lug nuts to 76 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Common problems reported by 2019 Lexus Rc owners, with recommended fixes and estimated repair costs.
Tire Information Label Non-Compliance (RC F)
The tire information label on certain 2022 RC F models does not list the vehicle's weight capacity, failing to comply with Federal Motor Vehicle Safety Standard number 110 for Tire Selection and Rims. This prevents the owner from knowing the maximum weight the vehicle can safely carry.
Lexus issued a recall (NHTSA 22V-615) to install a corrected tire information label that includes the missing weight capacity data. Dealers apply the updated label free of charge.
Est. Cost: Covered under recallFront Brake Squeal and Premature Wear
The RC 350 and RC F can develop front brake squeal during light braking, and some owners report premature brake pad wear, particularly on the RC F's larger performance brakes. The sport-tuned brake system generates heat and dust that contribute to noise.
Apply anti-squeal shim grease and install updated brake shims per the Lexus TSB. For the RC F, high-performance driving leads to accelerated pad consumption which is normal. Consider upgrading to aftermarket ceramic pads for reduced dust and noise in daily driving.
Est. Cost: $0 under warranty for shims; $300 - $700 for brake pad replacementInfotainment Touchpad Interface Difficulty
The 2022 RC uses the remote touchpad controller rather than a direct touchscreen, which many owners find unintuitive and imprecise. Navigating menus and selecting on-screen items while driving requires significant attention and is distracting.
Use voice commands for navigation and phone calls to minimize touchpad interaction while driving. Apple CarPlay (wired) provides a more familiar interface. Practice using the touchpad when parked to develop muscle memory for common functions.
Est. Cost: $0 (interface design limitation)HVAC Water Intrusion and Musty Odor
The HVAC evaporator drain tube can become clogged with debris or insect nests, particularly in warmer climates. This causes condensation to accumulate inside the HVAC housing, producing a musty or mildew odor from the air conditioning vents.
Lexus issued a TSB with procedures to clear the evaporator drain tube using compressed air and apply an antimicrobial treatment to the evaporator core. A protective drain mesh can be installed to prevent future blockages.
Est. Cost: $0 under warranty; $100 - $200 if out of warrantyRear Differential Whine (RC F / RC 350 AWD)
Some RC F and RC 350 AWD owners report a whining noise from the rear differential, most noticeable during deceleration between 30-50 mph. The noise can increase in cold weather and typically diminishes as the differential fluid warms up.
Drain and replace the rear differential fluid with the correct Lexus-specified gear oil. If the noise persists after a fluid change, the differential may need inspection for gear wear or bearing issues. Covered under the drivetrain warranty.
Est. Cost: $0 under warranty; $150 for fluid change; $1,500 - $3,000 for differential repair
