All 4 Known Issues
When Issues Typically Appear
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.
Common Symptoms
- Dead battery after sitting overnight or a few days
- Repeated need for jump-starts
- No-crank or weak crank
- Battery tests good initially but goes dead again
- Intermittent warning messages after low-voltage event
How to Fix
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.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- TipHave the dealer measure key-off parasitic draw after full sleep timeout; ask specifically whether the DCM/telematics module has applicable software updates or replacement guidance.
- TipIf the car is driven infrequently, owners often use a smart battery maintainer until the root cause is fixed.
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.
Common Symptoms
- Infotainment screen freezes
- CarPlay disconnects randomly
- Android Auto drops connection
- Audio cuts out or system reboots
- Slow startup of multimedia system
How to Fix
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.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- TipUpdate the phone OS and vehicle multimedia software, then re-pair the device from scratch before replacing hardware.
- TipUse a short, certified cable and clean the USB port if disconnects happen mostly over wired CarPlay/Android Auto.
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.
Common Symptoms
- Brake pedal pulsation
- Steering wheel shake while braking
- Vibration at highway speeds during deceleration
- Reduced braking smoothness
- Noise after repeated hard stops
How to Fix
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.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- TipAsk the shop to measure hub runout before installing new rotors; replacing parts without checking the hub can lead to repeat pulsation.
- TipUse OEM-quality pads/rotors and perform a proper bed-in cycle after replacement.
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.
Common Symptoms
- Buzzing from dashboard
- Door panel rattle
- Rear shelf or rear trim noise
- Noise worse on rough roads
- Rattle more noticeable in cold weather
How to Fix
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.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- TipOwners commonly use automotive felt tape or Tesa tape on contact points once the noise source is identified.
- TipRecord the noise on video and note speed/temperature to help the dealer reproduce the rattle during a test drive.
