Never buy Renault duster

Never buy Renault duster I have Renault Duster RXz 110ps with Mileage of 11.8 to 13.2km/L. Duster has a regular issue of (Engine part called) High pressure pump which delivers Diesel from Diesel tank to Engine. If you buy New duster, warranty conditions for this High Pressure pump is for 4 years or 80,000 kms whichever exceeded first. Whether you exceed this 80,000 km in 2 to 3 years, you are not eligible for replacement warranty. The other condition is that if you have missed a service to Renault service station. This High pressure pump becomes inoperative or less operative after 90,000 km run. It stops delivering diesel to engine & need to get replaced. New High Pressure pump company Price is 53,000 INR with 6 months warranty or 20,000 kms whichever exceeded first. Issue with my Duster is, I have consumed the 80,000 kms within 3 years and not eligible for the replacement warranty. Pump stops delivering diesel to engine (less delivery) when I cross 100 km/hour speed & engine light becomes visible in indicator which means engine is stop. As I slow down the car below 100 km/hour the pump start delivering proper amount of diesel to engine & the engine stop light disappears from indicator bar. So the alternative is whether you replace it with 53,000 INR or you can drive below 100 km/hour ( I did this below 100km/hour thing from august to December & drove the car more than 25,000 kms ). This issue is with every Renault duster car as my friend is having the same problem. When you ask about the reason, Renault service station or Renault gives an easy excuse about the diesel poor quality. They says that you might have pour some poor quality of diesel from any petroleum in past. Luckily I am a patrol pump dealer & I know about the best quality served in Gujarat so this excuse in completely unworthy. Other cars never have such poor quality issue but only Renault duster did. I will never go for Renault cars. I have Hyundai Creta & Ford eco sports as well, which are far better in mileage & many other ways. Renault is worthless & highly expensive.
