Renault Laguna reliability: what 25k MOT tests show
Across 25,018 MOT tests on Renault Laguna cars first used between 2004 and 2011, 53.6% passed first time. The figure for all cars is 71.7%. Compared only with cars tested at the same age, the Laguna is 5.8 points behind, so the model itself is below average, not just old. The most common reason for a fail is a broken coil spring.
Why Renault Lagunas fail the MOT
Of every hundred Lagunas that fail, about 22 are marked down for a broken coil spring and 18 for a sidelight not working. Percentages can add to more than 100 because one failed test often records several defects.
Suspension failures are the hard ones to see coming: a snapped coil spring or a worn ball joint gives little warning. Knocks over speed bumps are the clue.
Warning signs on the certificate
An advisory is the tester telling you what fails next year. On the Laguna the usual suspects are tyre tread below the legal minimum (20.2% of tests) and worn brake discs (18.6%). The advisory conversion table shows which of these are worth acting on first.

Set against the rest of the Renault range, which averages 62%, the Laguna at 53.6% is below par. Within the family, see the Clio (56.9%), Renault Captur reliability (77.6%), how the Megane does (54.7%) and Renault Kadjar MOT pass rate (76.8%), or the Renault range at the MOT. Buyers weighing a Laguna against other cars of similar popularity often compare it with the Toyota Land Cruiser (72.9%) and Ford Mustang (85.3%). The full reliability table puts them side by side, and the national MOT statistics give the baseline.

Questions people ask
Is the Renault Laguna reliable?
On MOT evidence the Renault Laguna is below average. It passes 53.6% of tests against 71.7% for all cars, and trails cars of the same age by 5.8 points. Figures from 25,018 DVSA tests.
What are the most common Renault Laguna MOT failures?
A broken coil spring (21.6% of failed tests), a sidelight not working (18%) and a split CV boot (13.9%). Suspension failures are the hard ones to see coming: a snapped coil spring or a worn ball joint gives little warning. Knocks over speed bumps are the clue.
What advisories does a Renault Laguna usually get?
Tyre tread below the legal minimum is the most frequent, noted on 20.2% of all Laguna tests, then worn brake discs (18.6%). An advisory passes the car today but marks the item most likely to fail next year.
How many miles a year does a Renault Laguna do?
About 7,905 miles a year on average, calculated from the odometer readings recorded at consecutive MOTs. That is close to the UK average of roughly 7,400.
