I have a 18 months old Range Rover Sport, which I bought couple weeks ago from dealership. Just today, I noticed that when taking my foot off the acceleration the car is losing it's speed quite quickly (unusually quick). In addition, it feels like the engine is working much harder to accelerate and maintain the speed. This did not occur before, so what could be the fault?

Check to see if any of your wheels are hot after a drive, it may be a caliper that is sticking, failing that, take it back to your dealer and ask them to check it out, its still under warranty i assume.

Thanks - heading to the dealership in morning. Quite annoying, dont expect to experience this for a relatively new car.

Any news on this?

was it the parking brake which needed adjustment?
