The Land Rover Defender (initially introduced as the Land Rover 110 / One Ten, and in 1984 joined by the Land Rover 90 / Ninety, plus the new, extra-length Land Rover 127 in 1985) is a series of British off-road cars and pickup trucks. They consistently have four-wheel drive, and were developed in the 1980s from the original Land Rover series which was launched at the Amsterdam Motor Show in April 1948. Following the 1989 introduction of the Land Rover Discovery, the term 'Land Rover' became the name of a broader marque, and thus no longer worked as the name of a specific model; thus in 1990 Land Rover renamed the 90 and 110 as Defender 90 and Defender 110 respectively. The 127 became the Defender 130.

The vehicle, a British equivalent of the Second World War derived (Willys) Jeep, gained a worldwide reputation for ruggedness and versatility. Using a steel ladder chassis and an aluminium alloy bodywork, the Land Rover originally used detuned versions of Rover engines. The original Defender is still being produced in developing countries despite the arrival of the Land Rover Defender (L663).

Though the Defender was not a new generation design, it incorporated significant changes, compared to the series Land Rovers, such as adopting coil springs front and rear, as opposed to all leaf springs on the previous; except for retaining rear leaf springs on high capacity (payload) models. Coil springs offered both better ride quality and improved axle articulation. Adding a lockable centre differential to the transfer case gave the Defender permanent (on-road) four-wheel-drive capability. Both changes were derived from the Range Rover, and the interiors were also modernised.

Externally, a full-length bonnet and full-width integrated grille and headlights, combined with (finally) a single-piece windscreen, plus widened wheel arches that covered new, wider-track axles were the most noticeable changes. Initially the engineering department conserved a part-time 4WD system, like on previous models, but it failed to sell, and this option was dropped in 1984. While the engine was carried over from the Series III, a new series of modern and more powerful engines was progressively introduced.

Even when ignoring the series Land Rovers and perhaps ongoing licence products, the 90/110 and Defender models' 33-year production run were ranked as the sixteenth longest single-generation car in history in 2020.

In 2020, Jaguar Land Rover introduced the first all new generation of Land Rover Defenders, switching from body on chassis to integrated bodywork and from live, rigid axles to all around independent suspension. While starting at a higher base price, the new model brought significant improvements to on road dynamics over the old model, air suspension is available on most trims. The range was originally limited to just two wheelbase lengths before a third, the Defender 130, was announced in 2022. The new Defender series is only available in closed, estate car bodies.

SERVICE BRAKES, HYDRAULIC,ENGINE AND ENGINE COOLING,VISIBILITY PROBLEM

Date Of Incident: 2005-11-17
VIN: SALNY22293A
Components: SERVICE BRAKES, HYDRAULIC,ENGINE AND ENGINE COOLING,VISIBILITY
Summary: AT 30,000 MILES, WE TOOK THE VEHICLE IN TO BE "SERVICED" MAINLY BECAUSE ANOTHER MECHANIC TOLD US THAT THE OIL WAS 'GUNKED'. THE DEALER INFORMED US THAT THERE WAS NO PROBLEM WITH THE VEHICLE OR THE WARRANTY AND REPLACED THE OIL AT A CHARGE OF OVER $94.00. THEN AT 34,000, THE BRAKES SUDDENLY BEGAN TO GRIND AND THE BRAKE LIGHT CAME ON, WE TOOK IT TO THE DEALER AND THEY SAID IT WAS "NORMAL WEAR AND TEAR" AND CHARGED US OVER $355.00 TO FIX THE BRAKES. AFTER ANOTHER 1,000 MILES, THE LIGHT CAME ON AGAIN, WHEN WE CALLED THEM THEY TOLD US TO LEAVE IT WITH THEM FOR A FEW WEEKS AND REFUSED US A LOANER CAR. ALSO, THE REAR DRIVER SIDE WINDOW WOULD NOT ROLL UP AND THEY REPLACE IT BECAUSE IT WAS 'UNDER WARRANTY'. AT 46,000 MILES THE ENGINE BEGAN TO OVER HEAT. I TOOK IT TO THE NEAREST MECHANIC AND WAS INFORMED THAT THE OIL AGAIN WAS 'GUNKED UP' BECAUSE ANTI FREEZE HAD BEEN LEAKING INTO THE ENGINE. AFTER 3 WEEKS, THE DEALER "LAND ROVER OF TULSA' FIRST TOLD US THAT THE ENGINE WOULD HAVE TO BE REPLACED. THEN LAND ROVER INC TRIED TO TELL US THAT THE ENGINE WOULD BE OUR EXPENSE. THEY TRIED TO INFORM US THAT THE VEHICLE HAD NOT BEEN PROPERLY SERVICED (EVEN THOUGH WE HAD TAKEN IT IN SEVERAL TIMES AT CONSIDERABLE EXPENSE). THEY KEPT THE VEHICLE FOR 3 WEEKS, AND THEN REPLACED SOME PART, TOLD US TO WATCH THE COOLANT AND TO HAVE THE OIL CHANGED EVERY 6,000 MILES. AFTER 247 MILES, HALF A GALLON OF ANTIFREEZE WAS GONE AND THE ENGINE STARTED TO RUN "FUNNY AGAIN". EVEN THOUGH THE DEALER CLAIMED THAT NO ANTI FREEZE WAS IN THE OIL, THEY FORGOT TO CLEAN THE OIL CAP AFTER THEIR "SERVICE". I HAD IT TESTED BY AN INDEPENDENT MECHANIC AND ANTI FREEZE WAS FOUND IN THE OIL CAP, WHICH PROVES ANTI FREEZE WAS IN THE OIL. ALSO, THEY CLAIMED A WHEEL BEARING WAS GOING OUT AND THEY WOULD ORDER THE PART AND FIX IT 'UNDER WARRANTY'. THEY SEEM CONFUSED THAT THEIR 'WARRANTY IS NOT A PICK AND CHOOSE TYPE WARRANTY. THIS VEHICLE IS OBVIOUSLY A LEMON. *JB
