Convertible Soft Top A-Pillar Light Gap
Some 2022-2024 LC 500 Convertible vehicles exhibit sunlight penetrating through a gap on the passenger side at the junction of the A-pillar and soft top. The gap allows a visible streak of light into the cabin, which can be distracting during daytime driving.
Lexus issued a TSB to adjust or replace the soft top seal at the A-pillar junction. The dealer inspects the seal alignment and installs an updated weather strip component. This is covered under the basic warranty.
Est. Cost: $0 under warrantyHigh-Friction Brake Pad Dust and Noise
The LC 500 and LC 500h are equipped with high-friction brake pads specifically designed for performance driving. These pads generate significant brake dust that coats the wheels and can produce more audible braking noise than typical luxury vehicles.
Lexus issued a TSB confirming this is a normal characteristic of the performance brake pad compound. Regular wheel cleaning is recommended. Aftermarket low-dust ceramic brake pads are available but may reduce high-speed braking performance. The OEM pads are engineered for the LC's weight and speed capability.
Est. Cost: $0 (normal characteristic); $300 - $600 for aftermarket low-dust pad upgradePanoramic View Monitor Display Delay
Vehicles equipped with the Panoramic View Monitor system may experience a delay in displaying the rearview camera image when the vehicle is shifted into reverse. The screen may briefly show a black image before the camera feed appears.
Lexus issued a recall for certain LC vehicles with PVM to update the parking assist ECU software. The update reduces the camera activation delay. Contact your dealer to check if your VIN is affected.
Est. Cost: Covered under recallIncompatible Aftermarket Wheel Hub Bolt Risk
If non-OEM wheels or hub bolts/nuts are installed on the LC, there is an increased risk that the wheels could come loose due to incompatible thread pitch or seat type. Lexus issued a TSB warning against using non-compatible wheel hardware.
Only use Lexus-approved wheels and hub bolts/nuts. If aftermarket wheels are desired, verify that the hub bolt specifications match OEM requirements (thread pitch, length, and seat type). Have lug nut torque rechecked at 50-100 miles after any wheel installation.
Est. Cost: $0 for torque check; $50 - $200 for correct wheel hardwareInfotainment System Responsiveness
The LC's infotainment system can feel sluggish in its response to touch inputs and menu transitions compared to newer Lexus models. The remote touch interface adds complexity, and wireless connectivity features like Bluetooth can be intermittent.
Ensure the infotainment system is running the latest firmware by visiting the dealer for software updates. A system reset can clear temporary sluggishness. Delete unused Bluetooth pairings to improve connection reliability.
