Renault Kadjar MOT failure rates: what fails, what to fix

TL;DR

The Renault Kadjar has a mixed record for MOT failures, commonly facing issues with brakes, suspension, lighting, and emissions. Fail rates increase with age, and repair costs can range from £50 for minor fixes to over £500 for significant repairs. Regular maintenance is crucial for reliability.

Common MOT Failure Categories

The Renault Kadjar often experiences failures in several key areas. The most frequent issues are related to brakes, suspension, lighting, and emissions. Brake problems typically stem from worn pads or discs, while suspension failures can be linked to worn shock absorbers or bushings. Lighting failures usually involve blown bulbs or faulty wiring. Emissions issues can arise from a malfunctioning exhaust system or catalytic converter, which can lead to significant repair costs if not addressed promptly.

Age-by-Age Fail Rate Trajectory

As the Kadjar ages, the MOT failure rate tends to increase. Newer models (2015-2017) usually have a lower failure rate, around 10-15%. However, as vehicles reach 5-7 years old, this can jump to 20-30%. Owners of older Kadjars should be particularly vigilant, as they may encounter more significant issues. For instance, models beyond 2018 have shown a slight improvement in reliability, but they still require regular maintenance to avoid common pitfalls.

Cost of Common Repairs

Repair costs for common MOT failures can vary widely. Simple fixes like replacing a bulb may cost around £50. Brake pad replacements can range from £150 to £300, depending on the parts used. More extensive repairs, such as replacing shock absorbers or addressing emissions issues, can exceed £500. Additionally, if electronic systems fail, such as dashboard warning lights or infotainment glitches, these can add to the overall maintenance costs.

Quick Fixes vs Structural Issues

Many common failures can be addressed with quick fixes. Replacing bulbs or adjusting brake components are straightforward tasks. However, structural issues, such as rust or corrosion, require more attention. These problems can be costly and may affect the vehicle’s safety and longevity. Owners should regularly inspect their Kadjars for signs of rust, especially in the undercarriage and around wheel arches, where moisture can accumulate.

What people are asking

Is the Renault Kadjar a reliable car?

The Renault Kadjar is generally considered to have a mixed reliability rating. While many owners report satisfactory performance without major issues, others have highlighted problems, particularly with electronic systems and some engine variants. Regular maintenance is key to ensuring longevity and reliability.

Which Kadjar model to avoid?

Buyers in UK communities have flagged that earlier models, particularly those manufactured before 2018, may have more frequent issues, especially with the CVT gearbox and electronic systems. It is advisable to look for later models that have benefited from updates and improvements.

What is the engine problem in the Renault Kadjar?

Some owners have reported issues with the TCE engines, particularly related to the turbocharger and fuel system. These problems can lead to reduced performance and increased repair costs if not addressed in a timely manner.

How long will a Renault Kadjar last?

With proper care and maintenance, a Renault Kadjar can last well over 100,000 miles. Factors such as driving habits, maintenance frequency, and environmental conditions will all impact the vehicle’s lifespan. Owners have noted that regular servicing significantly contributes to the vehicle’s longevity.

What owners say

Many owners on r/CarTalkUK report that the Renault Kadjar is a comfortable vehicle with a decent amount of space, making it suitable for families. However, some have experienced issues with the electronic systems, particularly the infotainment unit, which can be glitchy and unresponsive at times. These issues have led to frustration, especially when trying to use navigation or music features.

In terms of reliability, several users have shared positive experiences, stating that they have driven their Kadjars for considerable distances without major problems. For example, one owner mentioned driving over 30,000 miles in less than two years without any significant issues. This indicates that while some models may have problems, others can perform reliably over time.

On the downside, discussions on r/Renault highlight concerns about the CVT gearbox, with some owners experiencing slipping or hesitation during acceleration. This has raised concerns about the long-term durability of this transmission type, particularly in models with higher mileage.

Additionally, owners have pointed out that while the Kadjar is generally a good value for money, it is essential to be cautious about buying models with a history of electrical issues. Regular maintenance and checks can mitigate some of these concerns, ensuring that the vehicle remains in good condition.
