Which Q50 are you looking at?
Each Q50 generation has its own weak spots. Here are the known problems.
-
Suspension component excessive wear
Wear item V37The 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 to check: Walk around the car and push down firmly on each corner - the car should return to normal ride height with minimal bouncing. Excessive bouncing suggests worn dampers or worn suspension components. Examine the front wheel arches for any visible oil staining on shock absorber bodies or suspension c...
-
Fluid leaks from engine or transmission
Engine damage risk V37MOT 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 to check: Look under the car where it has been parked for any fresh oil stains or puddles on the ground. Note the colour - black indicates engine oil, red or brown suggests transmission fluid, green or pink indicates coolant. Examine the engine bay for any visible oil staining on the engine block, particul...
-
Premature brake pad wear
Safety and MOT risk V37This 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 to check: Look through the wheel spokes at the brake discs - you should see the outer pad material thickness. Pads should be at least 3mm thick for safe operation. Check for any rust staining or heat discolouration on the wheel rims, which suggests overheating brakes. Examine the brake discs for deep scori...
-
Wheel bearing excessive play
Wear item V37The 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 to check: Jack up each wheel individually and grab the tyre at the top and bottom - try to rock it in and out. Any noticeable movement indicates bearing wear. Spin each wheel by hand and listen for rumbling, grinding, or rough rotation - bearings should spin smoothly and quietly. Check for any heat buildup...
-
Brake disc excessive wear
Safety and MOT risk V37The 2.1-litre diesel Q50 shows brake disc wear at 2.1 times the national fleet average, concentrated around 60,000-80,000 miles. This correlates with the premature brake pad wear issue documented on the same variant, suggesting either aggressive braking characteristics or brake system design factors that accelerate wear of both pads and discs.
What to check: Examine the brake discs through the wheel spokes - look for deep scoring, excessive lip formation at the outer edge, or thickness variation between inner and outer disc surfaces. Check for blue heat discolouration on the disc surface, indicating overheating. Feel the disc surface with your finger...

Q50 questions
Is the Infiniti Q50 reliable?
17% of Q50 models fail their MOT based on 6,151 tests analysed. That’s about average for the class. There are 5 known problems to watch for, the most serious being suspension component excessive wear. A full history check shows whether a specific car has had related write-offs or insurance claims.
What are the main problems with a Infiniti Q50?
The most serious known issues are suspension component excessive wear, fluid leaks from engine or transmission, premature brake pad wear. Our car check flags whether a specific Q50 has been written off or had insurance claims linked to these faults.
How do I check if a Infiniti Q50 has outstanding finance?
Enter the registration on this page. We query Experian’s finance database and return any outstanding agreements within a minute. If finance is still owed, the finance company can legally repossess the car even after you’ve paid the seller. At £7.49 it’s the cheapest way to avoid a car that isn’t legally for sale.
How do I check if a Infiniti Q50 has been written off?
Our check queries Experian’s insurance write-off database for Cat A, B, S and N markers. A Cat S or N Q50 has been structurally or non-structurally damaged and repaired. This doesn’t mean it’s unsafe, but it affects resale value and some insurers won’t cover it. The check costs £7.49.
Can I check a Infiniti Q50 for free?
You can check MOT history free on GOV.UK, which shows past test results and advisories. What it won’t show is outstanding finance, write-offs or theft markers, which are the things that actually cost you money after you’ve bought. Our full check adds all of that for £7.49, using Experian data.
Is a Infiniti Q50 HPI check worth it?
HPI is one brand of car check. Our check uses the same Experian data covering finance, stolen, write-off and keeper history, plus MOT analysis and known Q50 faults that HPI doesn’t include. At £7.49 it’s typically less than half the price of an HPI check.
What does a Infiniti Q50 fail its MOT on?
The most common MOT failure on the Q50 is fluid leak. 17% of Q50 models fail overall, based on 6,151 tests. Checking a car’s full MOT history before buying shows you recurring problems the seller might not mention.
