Like every other SUV on the market, the Land Rover Discovery isn’t perfect. Some of its parts may fail or develop problems as the mileage accumulates. Here are some of the most common Land Rover Discovery failures through its model years:

1- Rear cargo door latch failure

Some owners have reported having difficulty getting into their Land Rover Discovery. Upon inspection, mechanics determined that an internal failure in the rear cargo door latch caused the problem.

2- Leaks in the head gaskets

Several Discovery owners also complained of leaking head gaskets and/or failed engine liners. Many drivers experienced misfiring and engine performance issues along with the leaks . This type of problem is reportedly common on some Land Rover Discovery vehicles from the years 1994-2004.

Don’t hesitate to take the SUV to an auto repair shop once you notice the signs of a coolant leak. To learn more about the risks of a blown or leaking head gasket.

3- Leaks in the throttle body depressurizer

Reports show that a damaged head gasket isn’t the only part that can leak coolant. Several owners have complained that their Discovery lost coolant due to a faulty throttle body de-icer. The coolant usually passes through the engine to the rear before reaching the ground . This issue is commonly seen on some units from model years 1994-2004.

4- Problems with the wiper switch

Some Land Rover Discovery units may develop wiper issues, especially during the colder months. Several owners have complained that their SUV’s windshield wipers were moving slower than usual, prompting them to have their vehicle serviced.

Most of them learned that they have a bad wiper switch. This problem is most frequently reported by owners of model years 1994-2004.

5- Sticky power switch

A sticky ignition switch is a commonly reported problem across several Land Rover Discovery model years (1994-2004). According to some owners, their vehicle’s ignition key got stuck due to this problem . In some cases, the ignition key was completely broken.

Labor costs for an ignition switch repair can run anywhere from $60 to $100.

6- Defective window regulators

The window regulator failure also affects many 1994-2004 Land Rover Discovery vehicles. There are many possible reasons why this happens, but a worn regulator seems to be the main cause of this problem on Land Rover Discovery vehicles.

The good thing is that replacing the faulty window regulator can easily correct this type of problem. Keep in mind that the labor cost for this type of problem is around 100-130 US dollars.

However, keep in mind that a failing window regulator is not the only problem that can cause power window problems.

7- Front differential failure

Several owners of model years 1994-2004 have reported that their front differential has failed. This is a serious problem because it can cause a “no drive condition”. This can start the vehicle even if it is not moving .

The differential controls the torque that is sent to the drive wheels. Without it, the wheels will not be able to rotate at different speeds without skidding. Due to its crucial role, it is important to address any differential issues immediately.

Rebuilding and replacing a differential assembly can cost anywhere from $2,000 to $3,000 in repairs.

Radiator problems are also seen on various model years of the Land Rover Discovery. If your vehicle’s radiator is clogged, it can cause the engine to overheat. This can damage surrounding components if left unaddressed, so it’s best to deal with the issue immediately. In most cases, cleaning the clogged radiator usually fixes the problem .

9- Failure of the main bearing

Some 1998 Land Rover Discovery owners have complained that the main bearing in their vehicles has failed, causing a drop in oil pressure. If this problem is not fixed, the motor can overheat and damage other components over time.

To fix the problem, mechanics often replace bearings that have failed. This may involve disassembling the engine and grinding the crankshaft. Repairs for these types of problems can reach $3,500.

Knowing the common failures of the Land Rover Discovery of the different years can help you decide which model year to buy. If you are buying a used SUV, make sure the seller has clarified everything before closing the deal.
