Car problems with Renault: common issues per 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 issues affect your Renault and how you can anticipate them.

The most 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 features. Even so, there are a few persistent problem areas. Electronics, automatic gearboxes and various sensors in particular regularly cause faults. In daily use this shows up as warning lights coming on, jerky driving behaviour or a car that 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 continue drawing power unexpectedly. A flat battery is the result. Defective sensors, such as the crankshaft sensor or wheel-speed sensors, also occur often. They send incorrect data to the on-board computer. 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 well-known phenomenon. Automatic and robotised gearboxes in particular often give trouble. Owners report jolts while shifting, slipping or a clear hesitation when pulling away from a standstill. These symptoms point to worn clutch plates or a defect in the mechatronics. The mechatronics unit is the control unit of the gearbox. These are much-reported issues especially in models such as the Captur with automatic transmission. Outside the warranty period they lead to expensive repairs.

Renault Clio – compact all-rounder with points to watch

The Renault Clio has been one of the most popular cars in its class for many years. Even so, this model also has its weak spots. Electronic faults and defective sensors occur regularly. The generation of the car determines which problems occur most frequently. In older models the suspension is a point to watch, particularly 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 especially important with this model. The timely replacement of the timing belt is as well.

Renault Mégane – popular hatchback with known weak points

With the Renault Mégane, electrical faults are a common theme. Think of problems with the electric window controls, a failing on-board computer or a key card. Sometimes the key card is not recognised. The suspension, in particular the ball joints and track-rod ends, can also show premature wear. Certain petrol and diesel engines suffer from specific engine faults. These are 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. The suspension and control arms are subjected to more stress. The high weight is the cause of this. In the interior, faults can occur in the seat systems or the dashboard. In diesel versions the EGR valve and turbo are components that require attention. That is certainly the case for cars that mostly do short trips. Do you cover long distances? Then check the cooling system and tyre pressures especially carefully before setting off.

Renault Twingo – city car with typical urban problems

As a typical city car, the Renault Twingo suffers from wear that matches its usage. In town there is a lot of accelerating, braking and shifting. As a result, the clutch and brakes wear faster than average. Minor electrical niggles are not uncommon either. Think of central locking that refuses to work or dashboard lighting that fails. With a Twingo you should also check for possible water leaks via the door seals or rear light units.

Renault Kangoo – small van and family people carrier under pressure

The Renault Kangoo is often used intensively. Families and business owners make heavy use of it. This leads to above-average wear on parts such as sliding doors and locks. The suspension can suffer under heavy loads. Rust, particularly around the sills and wheel arches, is something to watch for in older models. Diesel versions can develop problems with injectors and the particulate filter. That is especially the case when they mainly do short trips. The van versions generally have a harder life. They call for an even more critical inspection.

Renault Captur – popular crossover with focus on the gearbox

The Renault Captur is a popular crossover, but it has a number of specific issues. The automatic gearbox in particular is a frequent source of complaints. Jerky gear changes and hesitation when pulling away are often mentioned. Sometimes a gearbox software update brings improvement. In other cases a mechanical repair is required. Faults in the infotainment system also occur. Have the car read out at a garage in good time if you notice that the gearbox is not operating smoothly.

Renault Zoe – electric pioneer with 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 known phenomenon. Software faults in the Battery Management System (BMS) can lead to an incorrect range display. A message such as 'electric motor fault' is sometimes resolved with a software update. It is important to know which steps to take when charging does not start.

Renault Laguna – older mid-size car with known weaknesses

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

Renault Espace – large MPV and its long-distance issues

The Renault Espace is known for its space and comfort, but the complex electronics can cause problems. In models with air suspension this system can be prone to faults. Heavy use, such as towing a caravan, brings additional 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 from problems. The steering rack is prone to wear. The suspension is as well. Faults in the door locks and other small electrical niggles in the interior occur. Do you use the car for both short city journeys and longer motorway runs? Then a balanced maintenance strategy is important. That way you stay ahead of potential problems.

Renault Koleos – SUV with comfort and points to watch

With the Renault Koleos, problems can occur with the 4×4 system or the transmission. The electronics of driver-assistance systems, such as parking sensors and driving aids, are not always fault-free either. The Koleos is a heavy car. In addition, you can use it to tow a trailer or caravan. Wear to the brakes and drivetrain is therefore something to watch. During a test drive, pay close attention to how the gearbox shifts and to 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 known problems. Electronics and infotainment faults occur. Sometimes there are complaints about the engine software or emissions system. This shows up as an illuminated engine warning light. It is wise not to drive around with such faults for too long, and to have the car read out by a specialist.

Renault Trafic – van for intensive use

The Renault Trafic is a workhorse, and that brings specific wear with it. The gearbox has a hard life in daily professional use. The clutch too. In the diesel engines the particulate filter and EGR valve are well-known points of attention, especially in vans that do a lot of city driving. 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

With the Renault Master, engine and turbo problems are more common. This van often clocks up high mileages. The brakes and suspension wear faster due to the heavy loads. Electrical faults can occur in the load area or in the towbar installation. Are you responsible for a fleet? In that case, inspect the vehicles regularly for these known weak points. That way you safeguard their availability.

Recalls, software updates and warranty at Renault

Renault regularly carries out service campaigns and recalls. The aim is to resolve known problems. This is often done by means of software updates. Think, for instance, of updates for the engine management or gearbox control. There have recently been recalls for electric models. These were intended to solve starting problems. Check on the RDW website or via the dealer whether there is an outstanding recall for your car. Within the warranty period these updates are carried out free of charge.

Recognising car problems yourself and dealing smartly with the garage

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

Noises: Can you hear a rattling, knocking or grinding sound?
Warning lights: Do not ignore a warning light on your dashboard.
Driving behaviour: Does the car feel different, pull to one side or is the engine misfiring?

Make a systematic note of when a problem occurs. Does the car suddenly cut out? Then stop driving immediately. Do you see a red warning light? Then stop at once as well. Describe the complaint clearly. The garage will then be able to make a quicker and more targeted diagnosis.

‘ An inspection protects you from expensive surprises. ’

Is a used Renault a sensible choice?

A used Renault can be an excellent purchase, provided you know what to look out for. Models built after 2010 are generally more reliable than their predecessors. Check specifically for the known weak points of the model you have in mind. Think of the electronics and the automatic gearbox. Have an independent party carry out a thorough pre-purchase inspection. We always recommend this. An inspection protects you from expensive surprises. It also gives a clear picture of the car’s technical 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’s extensive used-car reviews and buying guides help you make the right choices so that you can take to the road with confidence. You will be prepared for possible issues. You will negotiate better on the price. You will also organise the maintenance of your car more effectively.
