Are Kia cars reliable?
Kia vs other premium brands
Kia vehicles pass their MOT at 74.7%, 2.8 points above the national average of 71.9% and one of the better mainstream performers. Skoda (76.1%) sits marginally higher, with Toyota (74.6%) and sister brand Hyundai (73.5%) close behind. Volkswagen (72.8%) sits just above national and Nissan (67.4%) trails.
The Kia range is anchored by the Sportage SUV, which alone accounts for 244,000 MOT tests. The Sportage passes at 75%, right at the brand average. The Picanto city car, second-highest volume at 175,000 tests, passes at 70%. The Niro hybrid at 87% is the range highlight.
Reliability data shows part of the picture. A vehicle history check reveals the rest, including outstanding finance, stolen markers, write-offs, and mileage discrepancies.
What is the Kia MOT pass rate by age?
Pass rate at each vehicle age, from 3 to 20 years old. National average shown for comparison.
Kia pass rates sit close to the national average in the first few years, then pull slightly ahead from about age 6 to 9. At age 3, Kias pass at 87.0% vs 87.5% nationally. By age 10 they are level again, at 69.3% vs 69.7%.
From about age 11 onward Kias fall behind. By age 16 the gap is 51.6% vs 56.9% nationally, and by age 20 it is 48.2% vs 56.9%. Kia sold in low volumes in the UK before the mid-2000s, so the surviving older Kias may be a small and mixed-quality sample that pulls the tail of the curve down.
What are the most common Kia faults?
Top 10 MOT failure categories for Kia, ranked by the share of failed tests they were found on. National percentage shown alongside.
Top 5 specific Kia failure reasons
These are the specific MOT examiner findings most frequently recorded on Kia vehicles, along with what they mean.
- Not working (found on 17.86% of failed Kia tests)
A lamp, indicator, or electrical component that has completely stopped functioning. Usually a blown bulb or faulty sensor.
- Does not clear the windscreen effectively (found on 9.91% of failed Kia tests)
- Tread depth below requirements of 1.6mm (found on 9.42% of failed Kia tests)
One or more tyres worn below the legal minimum tread depth. The legal limit is 1.6mm across the central three-quarters of the tyre.
- Less than 1.5 mm thick (found on 8.76% of failed Kia tests)
A brake pad measured below the minimum safe thickness of 1.5mm. Immediate replacement required to maintain braking performance.
- Efficiency below requirements (found on 8.25% of failed Kia tests)
Kia's failure profile has one clear tilt. Brake faults are found on 29.8% of failed tests vs 22.4% nationally, one of the highest brake shares of any mainstream brand and a pattern shared with sister brand Hyundai. Suspension faults at 23.6% and lamps and electrical faults at 31.2% both sit below the national averages of 32.4% and 38.2%.

How many miles do Kia vehicles typically cover?
Average recorded mileage at each MOT test, by vehicle age. National average shown for comparison.
Kia mileage sits a little below the national average early on and falls further behind with age. At age 3, Kias average 33,000 miles vs 34,000 nationally. At age 10, Kias average 74,000 vs 83,000, and by age 20 the gap is 83,000 vs 109,000. Kia ownership may skew toward lower-mileage private drivers.
Our Premium Vehicle Reports compare the recorded mileage at every MOT test to flag discrepancies. A drop in recorded mileage between two tests is a strong signal that the odometer may have been tampered with.
Are there any Kia safety recalls?
Safety recalls are issued by Kia when a manufacturing defect could affect the safety of the vehicle. The DVSA records every UK recall and links it to affected vehicle identification numbers (VINs). Recalls are free for the owner to have fixed at a franchised dealer.
Recall lists change over time as new issues are identified and old ones are resolved. For that reason we do not maintain a static list here. When you check a Kia via Brumble, the report shows any outstanding manufacturer safety recalls that still need action on that specific vehicle.
How do you check a Kia's full history?
Before you buy any used Kia, a full history check protects you from problems that a physical inspection would miss. Here is what a Premium Vehicle Report from Brumble covers.
Has this Kia been written off?
An insurance write-off means the car has been declared uneconomical to repair after an accident, fire, or flood. The report shows the category (Cat A, B, N, or S), the date, and the cause. Cat A and B are permanently unroadworthy. Cat N and S can legally return to the road but often carry hidden damage and are worth significantly less.
Is there outstanding finance on this Kia?
If the previous owner has an active HP, PCP, or loan agreement secured against the car, the finance company legally owns it until the balance is paid off. Buying a car with outstanding finance means the finance company can repossess it, even after you have paid the seller in full. The report checks with Experian for any active finance agreements.
Has this Kia been reported stolen?
The Police National Computer records stolen vehicles. The report checks the PNC for any active stolen marker. Buying a stolen vehicle means the police can seize it and return it to the rightful owner, with no compensation.
Has the mileage been tampered with?
Every MOT test records the current mileage. The report shows the full mileage history from every recorded test and flags any drops or unusually flat periods. A drop between tests is a strong signal the odometer has been clocked. A car worth £15,000 with 60,000 miles on the clock might be worth £10,000 if the true mileage is 120,000.
Has this Kia been used as a taxi or private hire vehicle?
Ex-taxis and private hire vehicles have typically covered high mileage under harder use than a private car of the same age. Insurers may view them as higher risk, and resale value is significantly lower. The report checks whether the vehicle has ever been registered as a taxi or private hire vehicle.
What is this Kia worth?
The report includes current trade, retail, and private-sale valuations based on the vehicle's make, model, trim, mileage, and condition. Use it to check whether the asking price is fair before you negotiate.
