2015-2025 model years · 3,000+ owner reports · Updated April 2026
According to Au7o's analysis of 3,000+ owner reports, the 2015-2025 Lexus RC has 7 documented known issues. No issues are rated critical, indicating generally reliable ownership. The most commonly reported issue is Dashboard Melting and Sticky Surface with 1,200 owner reports. Across all issues, repair costs range from $0 to $3,000. DIY maintenance guides at au7o.io.
On the 2015-2019 Lexus RC, early RC models use the same dashboard material prone to melting and developing a sticky surface in hot climates. The RC shares interior components with the IS, and the dashboard degrades identically when exposed to UV radiation and high temperatures. Lexus extended warranty coverage applies to affected RC models.
Contact Lexus dealer for dashboard replacement under the Customer Support Program. Document the condition with photographs showing the sticky surface and any windshield glare before visiting the dealer.

On the 2023-2025 Lexus RC, a recurring owner complaint on the RC coupe is trim-related rattles, especially from the door panels, dashboard area, and rear interior trim/shelf. The coupe body style, low-profile tires, and firm suspension tuning can transmit enough vibration to create intermittent buzzes that are difficult to duplicate at the dealer. While not a mechanical failure, the issue is well documented by owners and can be persistent on rough pavement or in cold weather.
Technicians usually need a ride-along to isolate the exact source, then remove trim panels and apply felt tape, foam isolators, or revised clips where panels contact each other. Re-torquing loose fasteners and checking for items in the trunk/rear shelf area can eliminate many noises. Because the problem is often intermittent, documenting road speed, temperature, and road surface helps diagnosis.

On the 2023-2025 Lexus RC, multiple late-model Toyota/Lexus owners, including RC-platform owners, have reported intermittent dead 12V batteries after the vehicle sits for a short period. The pattern is consistent with the Data Communication Module (DCM)/telematics system not entering sleep mode, causing parasitic draw and eventual no-start conditions. Owners typically experience repeated jump-starts, battery replacement that does not permanently solve the issue, and dealer diagnosis pointing to abnormal key-off current draw.
Confirm the complaint with a battery state-of-health test and a parasitic draw test after all modules should be asleep. If draw remains elevated, inspect DCM/telematics operation, software level, and related fuses/connectors; dealers typically apply software updates or replace the affected module if current draw remains out of spec. Battery replacement alone is often only a temporary fix unless the root parasitic draw is corrected.

On the 2023-2025 Lexus RC, owners have reported intermittent multimedia glitches on newer Lexus vehicles using the current infotainment stack, including frozen screens, delayed boot-up, dropped CarPlay/Android Auto sessions, and occasional audio loss until the system is restarted. On the RC, these complaints are especially frustrating because many climate, phone, and navigation functions are integrated with the head unit. The issue is usually software-related rather than a hardware failure, though some cases involve USB cable/port sensitivity.
Verify whether the problem occurs with both wired and wireless phone connections and check for multimedia software updates. Dealers typically update the head unit software, reset the multimedia system, and inspect USB ports/cables; if the issue persists, they may replace the head unit or related interface hardware. Using a high-quality certified cable often reduces disconnect complaints.

On the 2016-2022 Lexus RC 2.0L 8AR-FTS Turbo, the direct-injected 2.0L turbo in the RC200t and RC300 accumulates carbon deposits on the intake valves identically to the IS with the same engine. Without port injection to wash the valves, carbon buildup causes progressive performance degradation starting around 40,000 miles.
Walnut shell blasting of intake valves every 40,000-60,000 miles. Install an oil catch can to reduce the rate of carbon accumulation. Use top-tier fuel to minimize deposit formation.

On the 2023-2025 Lexus RC, owners of current RC models continue to report steering wheel shake or brake pedal pulsation during moderate-to-hard braking, often at relatively low mileage. In many cases the underlying issue is rotor thickness variation or pad material transfer rather than a true one-time rotor 'warp.' The symptom is more noticeable after repeated heat cycles, aggressive driving, or long periods of light use followed by harder braking.
Road-test to confirm pulsation and measure rotor runout and thickness variation with a dial indicator/micrometer. If out of spec, resurface or replace rotors and pads as a set, clean hub mating surfaces, and properly torque wheels to prevent recurrence. A proper bed-in procedure for new pads/rotors helps reduce repeat complaints.

On the 2015-2022 Lexus RC 5.0L 2UR-GSE, the Torsen limited-slip differential in the RC F develops a whining noise, particularly noticeable at highway speeds during deceleration. The gear mesh pattern wears unevenly over time, producing an audible whine that increases with speed. While not a safety concern, the noise is inconsistent with the luxury expectations of the vehicle.
Change the differential fluid to Toyota 75W-85 GL-5 synthetic gear oil, which can reduce the whine significantly. If the noise persists, the differential may need a ring and pinion gear replacement or complete assembly replacement. Adding a friction modifier specific to LSD clutch packs can also help.
