Top issues to watch for

The most serious Infiniti Q50 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Major
Suspension component excessive wear (V37)
V372013–202020k–150k miles
The failure pattern suggests premature wear of bushes, ball joints, or suspension arms rather than normal age-related deterioration. This high failure rate is specific to the diesel variant and represents the most significant documented reliability issue on this model.
What happens if ignoredWorn suspension components affect handling precision and braking stability, potentially compromising safety. Advanced wear can cause MOT failures and may lead to tyre damage from poor wheel alignment. Replacement typically involves multiple components as wear patterns often affect interconnected parts.

Major
Fluid leaks from engine or transmission (V37)
V372013–202020k–80k miles
MOT testers record this as leaks severe enough to pose environmental or safety risks, indicating significant seepage rather than minor weeping. The pattern suggests issues with engine or transmission seals developing relatively early in the vehicle's life.
What happens if ignoredSignificant fluid leaks lead to component damage if oil or transmission fluid levels drop. Engine oil leaks can cause fire risk if oil contacts hot exhaust components. Transmission fluid leaks lead to poor shifting performance and eventual transmission failure if levels become critically low.

Major
Premature brake pad wear (V37)
V372013–20200k–120k miles
This suggests either aggressive pad compound, binding calipers, or design issues causing accelerated pad consumption. The failure pattern affects all mileage ranges, indicating a systematic rather than age-related problem.
What happens if ignoredPads worn below 1.5mm thickness will cause MOT failure and risk damage to brake discs if not replaced promptly. Completely worn pads lead to metal-to-metal contact, causing disc scoring and potential brake system failure. Early pad replacement prevents more expensive disc replacement.

Major
Wheel bearing excessive play (V37)
V372013–202060k–100k miles
The 2.1-litre diesel Q50 shows wheel bearing play failures at 3.0 times the national fleet average, concentrated in the 60,000-100,000 mile range. Excessive bearing play indicates worn internal components that compromise wheel location and can lead to bearing collapse. This failure rate suggests the bearings may be undersized for the vehicle weight or subjected to higher loads than typical passenger cars.
What happens if ignoredWorn wheel bearings affect steering precision and can cause vibration through the steering wheel. Advanced wear leads to complete bearing failure, causing wheel instability and potential loss of control. Failed bearings require immediate replacement and may damage the hub assembly if neglected.
