The 2013 Lexus GS 350 is part of Lexus’s fifth-generation lineup and is generally regarded as a refined luxury sedan. While it offers strong reliability overall, owners and service history reveal several recurring issues that are more common as the car ages. This article surveys the problems most often reported by owners, what symptoms to look for, and practical steps to mitigate them.
In short, the most frequently reported problems involve powertrain and transmission quirks, oil consumption and engine misfires, electrical glitches in the infotainment system, and suspension or steering noises. The following sections break down these issues with context and guidance.
Powertrain and engine concerns
The engine and related systems are the heart of the GS 350. Some owners have reported issues that can affect performance and ongoing maintenance costs.
Common engine-related issues reported by owners include:
- Oil consumption: Several 2GR‑FSE engines in the GS 350 generation have been noted to burn or consume oil more than average. This can show up as the dipstick needing more frequent top-offs between oil changes, particularly as the mileage climbs.
- Engine misfires and rough idle: Misfire symptoms (rough running, fluctuating idle, or a check engine light with P030X codes) can arise from aging ignition coils or spark plugs and related ignition components. Replacement of coils and plugs is a typical repair path.
- Check engine light related to emission controls: O2 sensors, mass airflow sensors, or related emission-control components may trigger warnings, requiring diagnostic checks and, if needed, sensor replacement.
- Occasional hesitation or reduced power: Some drivers report brief hesitation or torque drop at certain RPMs, which can be linked to ignition or sensor issues, or fuel delivery concerns, and may warrant a diagnostic check of the engine management system.
Conclusion: Regular monitoring of oil level, timely ignition service, and periodic emissions diagnostics are prudent as the vehicle ages. If oil consumption seems abnormal, a dealer or qualified shop can perform more thorough checks to rule out leaks or internal engine wear.
Transmission and driveline concerns
The GS 350’s eight-speed automatic transmission is central to its smooth driving experience, but some models have shown shifting quirks as they age.
Common transmission-related issues reported by owners include:
- Rough or delayed shifting: Some drivers experience harsh or hesitant gear changes, particularly when the transmission is cold or under light load. This can feel like a shudder or clunk between gears.
- Shift hesitations or engagement problems: Occasional delays in engaging drive or reverse can occur, sometimes tied to fluid condition or transmission control module (TCM) behavior.
- Transmission fluid leaks or gasket seepage: Leaks around the pan or lines can occur over time and should be addressed to prevent low-fluid conditions that worsen shifting symptoms.
Conclusion: If you notice abrupt shifts, slipping, or unusual transmission behavior, have the system scanned for TCM or transmission codes and inspect the fluid condition and level. Addressing leaks promptly helps prevent further wear.
Electrical and electronics
The GS 350 features a reasonably sophisticated electrical and infotainment setup. With age, some components can become less reliable.
- Infotainment/navigation issues: Screens freezing, slow response, Bluetooth pairing trouble, or map/navigation glitches have been reported by some owners. Software updates or head-unit replacements are common remedies.
- Instrument cluster and sensor warnings: Occasional flickering gauges, intermittent warning lights, or sensor fault messages can occur, often traced to wiring, modules, or connectors that need inspection.
- Accessory and comfort-system glitches: Power seats, memory settings, or climate control quirks can become intermittently uncooperative and may require module resets or component replacement.
Conclusion: Software updates, firmware resets, and, when necessary, component replacements are typical paths for electrical issues. If symptoms persist, a dealership diagnostic is advisable to identify any underlying faults.
Suspension, steering, and braking
Wear and aging of suspension components can affect ride quality and handling, and some GS 350s report noises or degraded braking performance as mileage climbs.
- Front-end noises and worn bushings: Clunks, squeaks, or creaks from the front suspension, including control arm bushings, are commonly reported as weather and miles accrue.
- Brake rotor and pad concerns: Pulsation or groaning from brakes can be tied to rotor wear, pad life, or caliper assessment. Regular brake inspection helps catch uneven wear early.
- Steering and alignment issues: Worn steering rack components or tie-rod ends can contribute to vague steering feel or alignment drift over time.
Conclusion: Routine inspection of suspension and steering components, plus timely brake service, helps maintain ride quality and safety. If you hear unusual noises or feel changes in steering response, have a trusted shop inspect the suspension and steering linkage.
Recalls and maintenance considerations
Recalls and service bulletins can affect any aging GS 350, and it’s important to verify that open recalls are addressed and routine maintenance is up to date.
- Airbag and safety recalls: The 2013 GS 350 has been subject to Takata airbag inflator recalls and related safety notices. Check the VIN against recall databases to ensure all safety recalls are completed.
- General safety and component recalls: Other safety or system-wide recalls may exist depending on production date and region; verify with Lexus/ownership records for your specific vehicle.
Conclusion: Before buying or while maintaining a 2013 GS 350, run a current recall check and confirm that all open recalls have been repaired. Ongoing maintenance per Lexus guidelines remains important for long-term reliability.
What to check when buying a used 2013 GS 350
If you’re considering a used 2013 GS 350, focus on service history and a thorough pre-purchase inspection to uncover wear patterns that map to the issues above.
- Service history and maintenance records, especially for oil changes, ignition service, and transmission service intervals.
- Oil consumption history: document how quickly oil is consumed between changes and whether top-ups are necessary.
- Diagnostic codes: request a scan for any pending or historical engine, transmission, or electrical codes.
- Infotainment system status: confirm the head unit and navigation software function properly, with any updates completed.
- Recall status: verify all open recalls are resolved for the specific VIN.
Conclusion: A careful pre-purchase check can reveal whether the vehicle has been properly maintained and whether any of the common issues are likely to recur, helping you gauge future repair costs.
Summary
Overall, the 2013 GS 350 offers strong daily usability and refined driving dynamics, but its aging powertrain, transmission, electrical systems, and suspension components can present recurring challenges. Proactive maintenance, attentive monitoring of oil levels and transmission health, and timely addressing of electrical glitches or recalls can help owners maximize reliability and preserve resale value.
