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 on r/CarTalkUK 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 on r/Renault 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.
