The 2007 ES 350 is generally a reliable Lexus sedan, but like many aging cars, it can show certain wear patterns. The most frequently reported issues involve the drivetrain (shifting and leaks), engine sensors and lubrication, electrical systems, and suspension components. Regular maintenance and timely repairs can keep these cars running well.
As part of the XV40 generation, the 2007 ES 350 uses a 3.5-liter V6 (2GR-FE) paired with a five-speed automatic transmission. With higher mileage, owners commonly notice aging-related patterns in transmission behavior, seals and gaskets, sensors, and suspension parts. The sections below summarize typical symptoms, why they occur, and how to address them.
Drivetrain and transmission
These items cover the transmission and related drivetrain concerns commonly cited by owners of older ES 350 models.
- Harsh or inconsistent shifts, especially after the engine and transmission have warmed up.
- Occasional hesitation or slow downshifts that feel abrupt or unsettled.
- Torque converter shudder or slipping in some higher-mileage examples.
- Transmission fluid leaks from the pan, gasket, or lines, which can lead to low fluid levels and shifting issues.
To minimize risk, follow the factory service interval for fluid changes, use the correct Lexus/Toyota specification, and have a qualified technician inspect any shuddering or slipping promptly to avoid further damage.
Engine and fuel system
Problems in this area include oil handling and common sensor-related faults that can trip the check engine light or reduce performance.
- Oil leaks around valve cover gaskets or the rear main seal, which can produce smoke or odor and require gasket replacement.
- Oil consumption that seems higher than expected for the engine, particularly in higher-mileage examples.
- Ignition misfire codes or rough running due to aging spark plugs or ignition coils (P0300–P0306 range depending on cylinder).
- Faulty or dirty MAF (mass airflow) or O2 sensors causing rough idle, reduced fuel economy, or running rich/lean.
Address leaks promptly, monitor oil consumption, and replace ignition components and sensors per maintenance schedules to maintain smooth performance and efficiency.
Electrical and electronics
Electronic systems in the ES 350 can develop glitches as the car ages, affecting comfort and warning cues.
- Infotainment, gauge cluster, or navigation glitches, with occasional rebooting of radio or other electronic features.
- HVAC blower motor failure or reduced airflow, sometimes with inconsistent climate control performance.
- Power window regulator failures or slow operation of windows and mirrors.
- Warning lights such as ABS/Traction Control stay on due to wheel-speed sensor issues or brake actuator faults.
Electrical issues can be intermittent; if warning lights appear, have the system scanned to identify fault codes and address wiring, connectors, or sensor replacements as needed.
Chassis, suspension, and brakes
Wear items and suspension components can wear with age, affecting ride quality and handling.
- Worn front or rear suspension components, such as control arm bushings and strut mounts, leading to clunks or degraded alignment.
- Failing sway bar links or bushings causing knocking or vibrations over bumps.
- Power steering system leaks or pump issues, sometimes with whining noise or reduced steering assist.
- Brake wear or rotor runout, requiring timely pad/rotor replacement and checking for ABS-related faults.
Regular inspection of suspension and steering parts and prompt replacement of worn components helps preserve ride quality and safety.
Maintenance, recalls, and buying tips
Checking for recalls and staying on top of maintenance is essential when evaluating a used 2007 ES 350. Look up the vehicle’s VIN against recall databases to confirm campaigns (including airbag inflator recalls that affect many older Toyotas/Lexus models) and verify service history for key items such as transmission service, engine seals, ignition components, and suspension work. A pre-purchase inspection by a Lexus-trained technician can reveal wear patterns and help plan preventative maintenance.
When shopping for a used ES 350, prioritize cars with documented maintenance history and a clean record of transmission service, gasket replacements, ignition coil/plugs, and suspension components. Addressing issues early can prevent more costly repairs later.
Summary
The 2007 ES 350 offers solid reliability for a vehicle of its age, but owners should be mindful of common wear patterns in the drivetrain, engine lubrication and sensors, electrical systems, and suspension components. Regular maintenance, prompt diagnosis of symptoms, and thorough pre-purchase inspections can help keep these sedans running smoothly for many miles.
