Common issues include electrical faults and turbocharger problems, particularly in the 2016 and 2017 models. Owner feedback varies, with some praising comfort while others express reliability concerns.
MOT Pass Rates
The Renault Kadjar’s MOT pass rates fluctuate by year. For instance, the 2016 models show a pass rate of about 80%, while the 2017 versions drop to around 75%. The 2018 and 2019 models improve again, achieving pass rates closer to 85%. These figures suggest that later models may offer better reliability and fewer issues.
Common Failure Modes
Common failure modes include electrical faults, which often manifest as issues with the infotainment system and dashboard warning lights. Turbocharger problems are also reported, especially in models with the 1.5 dCi engine from 2015 to 2017. Furthermore, suspension components can wear prematurely, leading to costly repairs. Owners have also flagged issues with the CVT gearbox, particularly in models equipped with automatic transmissions, which can lead to slipping or erratic behaviour.
Year-by-Year Insights
The 2016 Kadjar is known for its electrical issues, while the 2017 model tends to have more significant turbocharger problems. The 2018 and 2019 models show improved reliability, with fewer reported faults. Buyers should be cautious with early models and consider the later years for a better experience. Additionally, some owners have reported that the infotainment system can be glitchy, particularly in earlier models, which detracts from the overall driving experience.
Owner Feedback
Owner reviews provide mixed feedback. Many appreciate the Kadjar’s comfort and driving experience. However, concerns frequently arise regarding reliability, particularly with earlier models. Owners have mentioned that while some have experienced no issues at all over years of ownership, others have faced repeated electrical faults that required multiple visits to dealerships for resolution. Additionally, discussions highlight that while the engine performance is generally good, the electronics often leave much to be desired, with some users reporting dissatisfaction with the automatic gearbox performance.
Furthermore, buyers in UK communities have flagged that the Kadjar’s overall build quality can vary, with some reporting rattles and trim issues, especially in the 2018 models. This suggests that while the Kadjar can be a comfortable and stylish choice, potential buyers should conduct thorough checks and consider the specific model year before making a purchase.
