France's carmaker since 1898 and inventor of the compact MPV. The 1.5 dCi diesel and naturally aspirated petrols are genuinely tough, but the 1.2 TCe is one of the worst mainstream engines of the 2010s. Know what's under the bonnet and a Renault is brilliant value.
| Engine | Found in | Verdict | Rating |
|---|---|---|---|
| K9K (1.5 dCi) | Clio II-V, Megane II-IV, Scenic II-IV, Captur, Kadjar (2001+) | Over 10 million produced. Routinely exceeds 300,000 km. Injectors and turbo are the main wear items at high mileage. Early Euro 4 versions had bearing wear. | Reliable |
| D4F (1.2 16V NA) | Clio II, Clio III, Twingo II, Modus (2001-2012) | Simple, naturally aspirated, and reliable. Replace the timing belt on schedule — it's an interference engine. Coil packs are the only common weak spot. | Reliable |
| K4M (1.6 16V NA) | Clio II/III, Megane II/III, Scenic II/III, Laguna (2001-2016) | Robust atmospheric engine with proven reliability. Low running costs and simple maintenance. VVT control valve is the only recurring issue. | Reliable |
| F4R (2.0 16V) | Clio RS 197/200, Megane RS 225/250, Scenic (2004-2018) | Strong naturally aspirated unit. In RS trim the gearbox synchros wear faster than the engine. Rear main seal leaks common after 60,000 miles. | Reliable |
| H5Ht (1.3 TCe) | Clio V, Captur Mk2, Kadjar, Megane IV, Scenic Mk4, Arkana (2018+) | Co-developed with Mercedes (A-Class uses it too). Better than the 1.2 TCe but watch for turbo pipe detachment, spark plug wear, and variable oil pump issues. Needs quality oil. | Caution |
| H4Bt (0.9 TCe) | Clio IV, Captur Mk1, Twingo III, Dacia Sandero (2012-2019) | Simple three-cylinder turbo with decent reliability when maintained. Timing chain plastic guides can degrade on neglected examples. Hard on spark plugs. | Caution |
| EDC dual-clutch gearbox | Clio IV/V, Captur, Megane, Scenic (paired with dCi and TCe engines) | Getrag-sourced dry-clutch unit prone to shudder, shift delays, and TCU overheating. Many faults are software-fixable, but hardware failure costs €1,200-2,500. Manual is always safer. | Caution |
| M5M (1.8 TCe) | Megane RS 280, Megane RS Trophy, Alpine A110 (2018+) | Powerful but check for oil pressure solenoid recall on 2018-2019 builds. Oil starvation can destroy the engine. Verify recall status before buying. | Caution |
| H5Ft (1.2 TCe) | Clio IV, Captur Mk1, Megane III/IV, Kadjar, Scenic III/IV (2012-2018) | Design flaw causes extreme oil consumption — over 1 litre per 1,000 km. Timing chain stretches prematurely at 80,000-120,000 km due to a clogging oil jet. Class-action lawsuit in France. Avoid. | Avoid |
Renault's EDC (Efficient Dual Clutch) gearbox, sourced from Getrag, suffers from low-speed shudder, delayed shifts, and TCU sensitivity to heat. The dry-clutch design is less durable than a traditional torque converter automatic. Many issues present as mechanical faults but are actually electrical or software-related. Repair costs €1,200-2,500 for hardware failure. Always prefer the manual transmission where available.
Turbo failure affects both the TCe petrol and dCi diesel ranges. On the 1.2 TCe, the turbo suffers from oil starvation linked to the engine's broader oil consumption problem. On the 1.5 dCi, neglected oil changes cause carbon contamination that can destroy a replacement turbo within a few thousand kilometres if the oil circuit is not thoroughly cleaned first. Budget €1,000-2,000 for replacement.
Renault's R-Link and MediaNav infotainment systems have a high failure rate. Touchscreens become unresponsive, software updates can brick the unit, and the NAND memory degrades over time causing boot loops. Replacement units are expensive from Renault. The systems used in 2012-2019 models are the worst affected. Later OpenR Link systems in the Megane E-Tech are significantly better.
Thermostat housing failures and coolant leaks are a recurring issue across multiple Renault model lines. The 1.3 TCe H5Ht is particularly affected, with coolant loss that can go unnoticed until the engine overheats. On older Scenic II and III models, blocked scuttle drains allow water into the cabin, damaging electronics under the carpet. Check coolant levels regularly on any Renault with a TCe engine.
