Nissan Leaf vs Tesla Model 3

Take the Nissan Leaf for lower age-adjusted MOT risk: its index is 109.2 versus 122.9 for the Tesla Model 3, and the 95% confidence intervals do not overlap.

Lower is better. The index adjusts for each fleet's exact age profile; the raw failure rate below does not. The index gap is 13.7 points. Data release dvsa-2024-v1.

Where their MOT failures diverge

These are component groups present in both models' published top-six failure lists, sorted by the absolute gap. A positive difference means the Nissan Leaf records more failure items; a negative one means the Tesla Model 3 does.

Failure items per 100 initial tests; difference = Nissan Leaf − Tesla Model 3

Counts are defect items, not the share of cars: one failed test can contain several items. A group absent from a model's top six is not treated as zero.

What the six-year test history says

The longitudinal layer follows the same vehicles between MOTs from 2019 to 2024. It separates a one-day retest from the harder question of what returns next year, and puts failures against miles actually driven.

Care proxy is descriptive, not a claim about an owner's character: a clean streak means three or more consecutive tests with nothing recorded; the repeat measure means the same advisory appeared at least three times.

More campaigns do not by themselves mean a less reliable car: recalls are manufacturer remedies, and the licensed-fleet denominator is unavailable for some families. Check a registration for outstanding work before buying.

Do other countries see the same thing?

Both models appear in the same independent national inspection datasets below. Compare each model with that country's own average; absolute pass rates are not portable between rulebooks.

Quick answers

Is the Nissan Leaf or the Tesla Model 3 more reliable?
The Nissan Leaf has the stronger age-adjusted MOT result: index 109.2 against 122.9 for the Tesla Model 3, with non-overlapping 95% confidence intervals.
Does the Nissan Leaf or the Tesla Model 3 fail more MOTs?
17.69% of Nissan Leaf initial tests and 14.03% of Tesla Model 3 initial tests found a failing defect in 2024. The lower raw rate belongs to the Tesla Model 3, but the age-adjusted index is the fairer model comparison because the fleets can be different ages.
What are the main MOT problem areas on the Nissan Leaf and Tesla Model 3?
The leading published failure group for the Nissan Leaf is visibility at 11.5 items per 100 tests; for the Tesla Model 3 it is tyres at 21.8 per 100.
Should I buy a Nissan Leaf or a Tesla Model 3?
If MOT reliability is the deciding factor, the Nissan Leaf is the evidence-led choice. Still check the individual car's MOT history and condition: these figures describe whole model populations, not a particular vehicle.

How to read and cite this comparison

Scope: class-4 vehicles, initial tests only, Great Britain 2024. PRS fixed-on-the-spot results count as failures because a defect was present on arrival. Index = observed initial failures ÷ age-profile-expected failures × 100; intervals are 95% confidence intervals. Every model family combines all generations and engines. Full method: methodology.
