Recalls and Technical Service Bulletins

Parking Brake Caliper Seizure

• Issue: Rear parking brake caliper may seize in the applied position.
• Action: Renault recall to replace affected calipers and update brake-management software.

Airbag Sensor Connector Corrosion

• Issue: Engine-bay moisture ingress can corrode driver-side impact-sensor connector.
• Action: TSB advises cleaning, applying dielectric grease and replacing corroded connectors.

Renault Latitude as a used car

The Renault Latitude arrived in 2010 as Renault’s contender in the D-segment sedan market, sharing its underpinnings with the Nissan Teana. Positioned above the Laguna and below the Talisman, it offered a spacious cabin, refined ride and a range of petrol and diesel powerplants. As a used purchase, the Latitude blends executive comfort with competitive pricing, though attention to known weak points and service history is essential.

Model Background

Market Position and Production

The Latitude launched in Europe, the Middle East and Asia between 2010 and 2015. Built in South Korea by Renault Samsung Motors, it was marketed locally as the SM5 and rebadged for global markets. Only one generation was sold in Europe, but body updates and engine upgrades arrived in 2013.

Design and Platform

Underpinned by the Nissan D-platform, the Latitude features a multilink rear suspension for improved ride comfort. Exterior styling was conservative, with a long bonnet, gently sloping roofline and understated chrome touches. Inside, soft-touch dash materials and chromed air-vent surrounds gave it an upscale feel.

Engine and Transmission Options

Petrol Engines

• The 2.0-litre four-cylinder delivers smooth midrange pull and returns around 8.0 L/100 km in mixed driving.
• The 2.5-litre V6 offers more linear torque but trades economy for roughly 10 L/100 km real-world consumption.

Diesel Engines

• The 150-horsepower dCi combines 320 Nm of torque with a WLTP-rated 5.5 L/100 km.
• The 175-horsepower MD (Medium Duty) variant adds stronger throttle response and towing capability.

Transmission Choices

• Six-speed manual gearboxes are robust but require clutch replacement around 120 000 km.
• The CVT automatic provides seamless shifts but demands fluid changes every 60 000 km to avoid belt slippage and judder.

Dimensions and Capacities

Interior Space and Comfort

Rear legroom of 300 mm behind the front seats and a flat floor ensure three adults ride in comfort. High-mounted dashboard vents deliver consistent airflow, and front seats feature adjustable lumbar support in higher trims.

Performance and Fuel Economy

Trim Levels and Standard Equipment

Authentique (Base)

Includes manual air-conditioning, cloth upholstery, single-CD radio with Aux input and steel wheels with hubcaps.

Reliability and Known Issues

Diesel Particular Faults

Diesel particulate filter clogging is common if the car is used for short trips. Forced regeneration or professional cleaning can restore flow but replacement is costly.

EGR Valve and Coolant Leaks

Carbon buildup in the EGR cooler leads to rough idle and reduced performance. Coolant hoses nearby can split; inspect for wet spots under the engine bay.

CVT Maintenance

Delayed maintenance on CVT fluid leads to belt slippage and judder. Ensure service records show fluid and filter changes every 60 000 km.

Suspension and Steering

Front lower-arm bushes wear around 100 000 km, creating clunks over bumps. Electric power-steering pumps may whine when fluid is contaminated.

Maintenance and Ownership Costs

Scheduled Service Intervals

• Oil and filter change every 15 000 km or 12 months.
• Brake fluid renewal every 24 months.
• CVT fluid and filter service every 60 000 km.
• Timing belt and water pump replacement at 120 000 km or six years.

Typical Repair Costs

Used Car Buying Tips

What to Inspect

• Check for soot or oil residue around the DPF and EGR cooler.
• Verify smooth shift patterns in both manual and CVT transmissions.
• Inspect underbody and wheel arches for rust, especially near chassis joints.
• Test all electronics, including climate controls, infotainment and power seats.

Service History Checklist

• Confirm regular oil changes with quality synthetic oil.
• Look for CVT service stamps at proper intervals.
• Ensure timing belt and water pump replacements are documented.
• Review any recall or software-update history via VIN check.

Pricing and Depreciation

Latitude values drop sharply in the first three years—up to 50 percent—then stabilize. Diesel models with comprehensive service records hold value best, while high-trim petrol-powered cars can be bargains if mileage remains moderate.

Conclusion

As a used executive sedan, the Renault Latitude offers generous cabin space, a composed ride and well-specced trim levels at accessible prices. Thorough pre-purchase checks on the DPF, EGR system, transmission service history and suspension components will ensure you secure a reliable example. With diligent maintenance and an eye on known weak points, the Latitude can deliver comfortable daily driving and long motorway journeys without exceeding your budget.
