Build my inspection planFrequently asked questions
Is the Kadjar just a Qashqai?
It shares the platform and engines, so the mechanical checks are the same, but it is usually cheaper to buy.
What is the best value spec?
Mid-range trim with navigation and a camera. It presents well without a big price gap.
Where do dealers lose money?
Emissions hardware on town-used diesels. Test properly before you commit.
Which petrol engine is more reliable, the 1.2 TCe or 1.3 TCe?
The later 1.3 TCe, introduced in late 2018, is significantly more reliable. The earlier 1.2 TCe is notorious for excessive oil consumption and premature timing chain stretch. Dealers should actively seek out 1.3 TCe stock, as it offers better performance and drastically reduces the risk of expensive warranty claims.
When does the timing belt need replacing on the 1.5 dCi?
The 1.5 dCi engine requires a timing belt and water pump replacement every five years or 90,000 miles, whichever comes first. Always check the service history for this specific invoice, as a missed replacement represents a significant forecourt prep expense and a major risk of catastrophic engine failure.
Are there any specific issues with the Kadjar's keyless entry system?
The Renault hands-free keycard system is prone to intermittent failure caused by damaged internal microswitches or water ingress into the exterior door handle proximity sensors. Always test that the vehicle locks and unlocks automatically as you walk away and approach with the keycard in your pocket.
