Car problems with Renault: common issues by model and what you can do about them

Car problems with Renault can often be traced back to specific weak spots in the electronics and transmission, which manifest differently in each model. Knowing these points of attention is what makes the difference between a reliable car and unexpected garage bills. Read on and discover which known problems affect your Renault and how you can anticipate them.

Common car problems with Renault at a glance

Over the years, Renault has built up a mixed reputation when it comes to reliability. Many models are known for their comfort and practical qualities. Even so, there are some persistent problem areas. Electronics, automatic gearboxes and various sensors in particular regularly cause faults. In daily use you notice this through warning lights coming on, jerky driving behaviour or a car that suddenly goes into limp mode. Sometimes the car stops altogether. This article zooms in on the most common problems per model and gives you practical, real-world tips.

‘ The car then only delivers limited power. ’

Electronics and electrical systems in Renaults

One of the most frequently reported complaints in various Renault models concerns the electronics. Faults in control modules can cause systems to keep drawing power unexpectedly. A flat battery is the result. Defective sensors, such as the crankshaft sensor or wheel speed sensors, are also common. These send incorrect data to the ECU. That leads to starting problems or the activation of limp mode. The car then only delivers limited power. On the dashboard you recognise these problems by warning lights or 'STOP' messages.

Transmission and drivetrain problems

Problems with the drivetrain are a familiar phenomenon. Automatic and robotised gearboxes in particular regularly give trouble. Owners report jolts when changing gear, slipping, or clear hesitation when pulling away from a standstill. These symptoms point to wear of the clutch plates or a defect in the mechatronics unit. The mechatronics is the control unit of the gearbox. These are frequently reported issues especially on models such as the Captur with an automatic gearbox. Outside the warranty period they can lead to expensive repairs.

Renault Clio – versatile compact car with some points to watch

The Renault Clio has been one of the most popular cars in its class for years. Even so, this model also has its weak spots. Electronic faults and defective sensors are common. The generation of the car determines which problems occur most often. In older models the suspension is a point of attention, in particular the control arms and shock absorbers. When buying a used Clio, check the service history. During a test drive, listen for any unusual noises from the suspension. Preventive maintenance on the engine is particularly important with this model, as is replacing the timing belt on time.

Renault Mégane – popular hatchback with known weak spots

Electrical faults are a familiar theme in the Renault Mégane. Think of problems with the electric window controls, a failing on-board computer or a key card. The key card is sometimes not recognised. The suspension, particularly the ball joints and track rod ends, can also show premature wear. Certain petrol and diesel engines are prone to specific engine problems, often related to the ignition or fuel system. A proper diagnosis by the garage can prevent unnecessary replacement of parts.

Renault Scénic – family MPV and its wear from heavy use

The Renault Scénic is often heavily used as a family car, which leads to specific wear patterns. The springs and control arms have a tougher time, due to the higher weight. Inside, faults can occur in the seat mechanisms or the dashboard. On diesel versions, the EGR valve and turbo are parts that need attention, especially on cars that are used mostly for short trips. Do you drive long distances? Then double-check the cooling system and tyre pressure before you set off.

Renault Twingo – city car with typical urban issues

As a typical city car, the Renault Twingo suffers from wear that matches its usage. In town you accelerate, brake and change gear a lot. As a result, the clutch and brakes wear faster than average. Small electrical niggles are not uncommon either. Think of central locking that stops working or dashboard lighting that fails. With a Twingo, also check for possible water leaks through the door seals or rear light units.

Renault Kangoo – small van and family runabout under pressure

The Renault Kangoo is often used intensively. Families and business owners put a lot of miles on them. This leads to above-average wear on parts such as sliding doors and locks. The suspension can suffer from heavy loads. Rust, especially on the sills and wheel arches, is something to watch out for on older models. Diesel versions can develop problems with the injectors and the particulate filter, particularly when they are mostly driven on short runs. The van versions generally have a harder life and need an even more critical inspection.

Renault Captur – popular crossover with focus on transmission issues

The Renault Captur is a popular crossover, but it has a number of specific problems. The automatic gearbox in particular is a frequent source of complaints. Jerky gearchanges and hesitation when pulling away are common. Sometimes a gearbox software update offers relief. In other cases, a mechanical repair is needed. Faults in the infotainment system also occur. If you notice that the transmission is not operating smoothly, have the car read out at a garage in good time.

Renault Zoe – electric pioneer and EV-specific issues

As one of the first popular electric cars, the Renault Zoe also has its own EV-specific problems. Charging issues, where the car refuses to charge at a public charge point or at home, are a familiar phenomenon. Software faults in the Battery Management System (BMS) can lead to an incorrect range display. A warning such as 'electric motor fault' can sometimes be resolved with a software update. It is important to know what steps to take if charging does not start.

Renault Laguna – older mid-size model with well-known weaknesses

The Renault Laguna, particularly the second generation, struggled with a reputation for electronic problems. The key card was a notorious source of failures, as was the start/stop system. The suspension and turbodiesel engines were also prone to defects. Considering a used Laguna? Then check the full service history. Make sure any modifications or recall work have been carried out.

Renault Espace – large MPV and its long-distance issues

The Renault Espace is known for its space and comfort, but its complex electronics can cause problems. On models with air suspension this system can be prone to faults. Heavy use, such as towing a caravan, brings extra risks. Cooling problems can then arise. The diesel engines are generally reliable, provided they are properly maintained. We recommend a preventive check of the cooling system and fluid levels before a long holiday trip.

Renault Modus – compact MPV for town and family use

The Renault Modus combines compact dimensions with a practical interior, but it is not free of problems. The steering rack is prone to wear, as is the suspension. Faults with the door locks and other minor electrical issues in the interior are not uncommon. Do you use the car for both short city trips and longer motorway journeys? Then a balanced maintenance strategy is important, so you can stay ahead of problems.

Renault Koleos – SUV with comfort and points to watch

On the Renault Koleos, problems can occur with the 4×4 system or the gearbox. The electronics of assistance systems such as parking sensors and driver aids are also not always fault-free. The Koleos is a heavy car, and you can tow a trailer or caravan with it. Wear on the brakes and drivetrain is therefore something to watch closely. During a test drive, pay close attention to the gearchange quality and any unusual noises from the drivetrain.

Renault Kadjar – crossover with shared technology

The Renault Kadjar shares its technology with other models from the Renault-Nissan alliance. As a result, it also shares some of the familiar problems. Electrical and infotainment faults occur. There are sometimes complaints about the engine software or emissions system, which show up as an illuminated engine fault light. When such faults occur, it is wise not to keep driving for long and to have the car read out by a specialist.

Renault Trafic – van for intensive professional use

The Renault Trafic is a workhorse, and that brings specific wear issues with it. The gearbox has a hard life in daily professional use, and so does the clutch. On the diesel engines, the particulate filter and EGR valve are known weak points, especially on vans that spend a lot of time in town. As a business owner, follow the prescribed service schedule strictly. That way you avoid downtime and unexpected costs.

Renault Master – large van with high mileages

On the Renault Master, engine and turbo problems are more common. This van often covers very high mileages. The brakes and suspension wear faster because of the heavy loads. Electrical faults can occur in the load area or towing electrics. Are you a fleet manager? In that case, inspect the vehicles regularly for these known weak spots, so you can guarantee their availability.

Recalls, software updates and warranty on Renaults

Renault regularly carries out service campaigns and recalls in order to resolve known problems. This is often done through software updates, for example for the engine management or gearbox control. Recently there have been recalls for electric models to remedy starting problems. Check on the RDW (Driver and Vehicle Standards Agency equivalent in the Netherlands) website or with your dealer whether there is an outstanding recall for your car. Within the warranty period these updates are carried out free of charge.

Spotting car problems yourself and dealing smartly with the garage

As a Renault driver you can spot many problems in time yourself. Watch out for the following signals:

Noises: Do you hear a rattling, knocking or grinding noise?
Warning lights: Do not ignore any warning light that comes on in your dashboard.
Driving behaviour: Does the car feel different, pull to one side or is the engine hesitating?

Systematically note when a problem occurs. Does the car suddenly cut out? Then stop driving immediately. Do you see a red warning light? Again, pull over straight away. Describe the complaint clearly; that way the garage can make a faster and more accurate diagnosis.

‘ An inspection protects you from expensive surprises. ’

Is a used Renault a sensible choice?

A used Renault can be an excellent buy, as long as you know what to look out for. Models built after 2010 are generally more reliable than their predecessors. Pay particular attention to the known weak points of the model you are considering, such as the electronics and automatic gearbox. Always have an independent party carry out a thorough pre-purchase inspection. An inspection protects you from expensive surprises and gives you a clear picture of the car's mechanical condition.

A Renault with a known weak spot does not have to be a problem, as long as you know what to expect. Preventive maintenance and the right knowledge help you avoid many unexpected costs. Carnews' extensive used-car reviews and buying guides help you make the right choices, so you can take to the road with confidence. You'll be prepared for possible issues, negotiate a better price, and take care of your car's maintenance more effectively.
