Renault has the lowest first-time MOT pass rate of any mainstream brand we track. That is not a comfortable sentence for a warranty company to publish about cars it insures, but you would find out eventually and it is better you hear it straight.
How long does the Renault warranty last?
Three years — unlimited mileage for the first 24 months, then capped at 60,000 miles in year three.
Same structure as Peugeot, and the same trap: two years of genuinely unrestricted cover followed by a year where the mileage cap can end things early. A driver doing 35,000 miles a year is through 60,000 before the second birthday and effectively has two years of cover, not three.
There is no extension scheme beyond that. When the three years are up, that is the end of factory cover. Check your own paperwork, as terms vary by model.
What does the MOT data say about Renault?
Renault's first-time pass rate was 71.8% in the DVSA's 2024 test year. The average across the 25 brands we track is 78.0%. Only Saab, Citroen and Chevrolet scored lower, and two of those no longer sell cars here.
Nearly three in ten Renaults fail first time.
There is context worth having. Renault's UK fleet is old — a lot of Clios and Meganes from the 2010s are still going, and age is the single biggest predictor of MOT failure. The brand also sells heavily into the small-car and van-derived market, where cars work harder and are maintained on tighter budgets.
But we are not going to spin it into a good result. It is a poor one. What it should change is how you budget, not necessarily whether you buy the car — plenty of people run Renaults happily for years by simply staying on top of maintenance.
What tends to go wrong on a Renault?
- Electrical faults — sensors, switches, control modules and the associated warning lights. The brand's most consistent complaint.
- Suspension components at £150–£600, which the MOT numbers reflect directly.
- Turbo failures on some diesel engines, especially on cars doing short urban runs.
- Clutch and gearbox wear — clutch replacement £300–£600, gearbox replacement anywhere from £800 to £3,000.
- Cooling system problems, which escalate fast if ignored. A temperature gauge creeping up is not something to drive on.
- DPF blockages on diesels used for stop-start journeys.
That gearbox range is the one to notice. At the top end it exceeds our £3,000 claim limit, and on an older Renault it can exceed the value of the car. Worth being honest with yourself about that before paying for cover.
What does independent cover include on a Renault?
Engine and major internals, manual and automatic transmissions, clutch components, turbo or supercharger, differential and driveline, braking, steering and suspension, the cooling system, listed electrical components including control units and wiring, the fuel system and air conditioning.
Given where Renault's faults cluster, the electrical and cooling cover is the part doing the most work. Radiators, water pumps, cooling-fan motors, thermostats and temperature sensors are all in the schedule.
£3,000 per authorised claim, £100 excess, labour to £100 per hour. Turbo cover ends at 7 years or 80,000 miles, which on a diesel Renault is often the limit that matters most.
Excluded: wear and tear, servicing, consumables, accidental damage, pre-existing faults, DPF blockage caused by unsuitable use.
Is a warranty worth it on a Renault?
Three things decide it, and they are worth working through properly rather than taking our word for it.
The car's value against the repair. If your Renault is worth £2,500 and a gearbox is £3,000, the realistic outcome of a major failure is that you scrap it. Cover does not change that arithmetic much. On a newer, more valuable example it changes it a lot.
The service history. On a brand with this pass rate, documented maintenance is doing double duty — it keeps the car healthy and it makes a claim stand up. Gaps are a real problem here.
What you are actually worried about. If it is the endless small electrical niggles, cover helps with the ones involving a failed component and not at all with the ones that are just irritating. If it is a big engine, gearbox or turbo bill, that is squarely what the product is for.
Our honest position: a well-maintained, reasonably valued Renault inside the age and mileage limits is a sensible candidate for cover. A high-mileage, patchy-history example worth less than the repairs is not, and we would rather say so than take the money.
