RepairPal Expert Overview:

The engine throttle can stick intermittently during its operation. The exact point of sticking is not predictable and can result in a higher than expected engine speed. If this is encountered, the driver may experience difficulty bringing the vehicle to a stop, increasing the risk of a crash. Dealers will replace the throttle body to correct this concern. The Land Rover recall number is D117/B150.

2003 Land Rover Discovery Reviews

If you bought one of these to drive around town and road-trip to LA....you got the wrong rig. Go buy some floaty American SUV. If you're an outdoor enthusiast that likes to take the road less traveled, have a passion for surfing spots in Baja that can't be accessed without a mule or airplane...here is your mule. Truck ALWAYS starts...never a hiccup. It's still running a good old fashioned "buick" engine that have been rolling in Rovers since the 60's. Yep they have issues but nothing unusual. Oil leaks will develop, not much more than torquing or replacing aged gaskets. Change the fluid in the difs and tranny which is what the vehicle is all about and you'll get many years of service from it. electronics are not sophisticated, the sensors can get expensive but there are several good LR parts houses on the net. DO NOT go to the dealer after warranty.....it will be almost triple the cost of an independent.
Rugged and ready to assault the ribbons of unpaved roads....and throw in some snow now and then.
Those that complain about LRs, bought one for all the wrong reasons..they wanted some "status" symbol from a truck used by farmers the world over...come on. These are a good DIY repair vehicle on most aspects too.

Off-road - no problem. Snow storms - handles extremely well. Principle mode of transportation - NO WAY. Dealers are vampires and service reps are minions of the dealer. I cannot believe how badly serviced this vehicle is. Oil pump has a serious design flaw, ABS system sucks, legacy electrical problems that have haunted this vehicle for more than 10 years. LR has known about these faults for years but does nothing. Better to say nothing than recall all those lemons - right? Looks great but no substance. Take a lesson from GMC or Ford trucks and give us LR owners a break. TATA owns this now and I wonder if they'll do any better.
