The contact owns a 2004 Land Rover Discovery. The contact stated that the check engine warning light was illuminated. While driving approximately 35 MPH and depressing the brake pedal, the brakes failed to immediately stop the vehicle. The contact aggressively slammed on the brake pedal to stop the vehicle. Additionally, while driving at various speeds, the vehicle was slightly drifting to the left. The vehicle was taken to a certified mechanic, who diagnosed that the EVAP was leaking and needed to be replaced. The EVAP was replaced. The mechanic had not diagnosed the brake failure. The vehicle was picked up, and the dealer informed the contact to drive the vehicle for another 25 miles to see if the check engine warning light would illuminate again. The contact stated that after leaving the dealer, 48 miles later, the check engine warning light illuminated again. The contact called the mechanic, who decided not to inspect the vehicle again, but instead refunded the cost for the previous repair. The manufacturer was not informed of the failure. The failure mileage was approximately 106,683.

Defect investigations
Brake light switch failure
On june 16, 2005, the office of defects investigation (odi) opened a preliminary evaluation (pe05-034) to investigate alleged stop lamp (brake) switch failures in certain model year (my) 2004 land rover discovery series ii vehicles.on october 14, 2005, the investigation was upgraded to an engineering analysis and the scope expanded to include certain my 2002 through 2005 freelander vehicles that use a substantially similar self-adjusting stop lamp switch furnished by the same supplier, methode electronics malta, ltd. (methode).in september 2003, methode moved the production of an internal switch component, known as the slider mechanism, from a validated plastic injection-molding tool (?cavity 1?) to another tool (?cavity 2?) that had not been used before to produce parts for land rover.sliders from cavity 2 may be characterized by poor fill, lack of definition in the slider teeth and dimensional instability.consequently, the slider may be unable to restrain improper movement of the plunger during normal brake pedal operation.this may cause the switch to fall out of adjustment, thus significantly reducing the effort required to energize the switch and illuminate the stop lamps.?cavity 2? Switches were installed in approximately 8,763 discovery subject vehicles built from december 2003 through may 2004 and approximately 3,915 freelander subject vehicles built from october 2003 through may 2004.additionally, stop lamp switches in certain my 2002 through 2005 freelander subject vehicles may slip out of adjustment as a result of switch damage due to an incorrect setting procedure during vehicle manufacture or as a result of switch mounting bracket flex.analysis of all available data indicates the predominant failure mode is constant stop lamp illumination.other reported consequences of stop lamp switch maladjustment include inoperative automatic transmission gear selector/brake pedal shift interlock, inoperative speed (cruise) control, and telltale illumination as described in technical service bulletin (tsb) no. Lt206-001 dated october 28, 2004 issued by the manufacturer to land rover dealers in the united kingdom (uk).to date, odi is aware of 77 non-duplicative complaints that allege stop lamp switch failure on the subject vehicles (10 complaints on my 2004 discovery, 45 on my 2002 freelander, 19 on my 2003 freelander, and 3 on my 2004 freelander vehicles).additionally, 4,595 discovery and 13,370 freelander subject vehicles have experienced one or more warranty claims to replace the stop lamp switch.of the 5,170 warranty claims paid to replace stop lamp switches on discovery subject vehicles, approximately 31% occurred before the vehicle was sold new and approximately 88% occurred within the first 12 months of vehicle service.the warranty trend on discovery subject vehicles is in decline with 3,545 claims paid in calendar year (cy) 2004, 1,303 claims paid in cy 2005, and 322 claims paid in cy 2006 through september 28, 2006 (which is when odi last received updated warranty claims data from land rover), and it appears that the alleged defect on discover subject vehicles has been remedied through warranty repairs.however, odi analysis of the manufacturer?s warranty and complaint records indicates the failure trend on certain freelander subject vehicles is ongoing.by letter dated february 2, 2007, land rover has notified odi that it will conduct a safety recall (the federal safety agency recall no. 07v‑041) to replace defective stop lamp switches in approximately 33,247 my 2002 through 2005 freelander vehicles built at the solihull, uk assembly plant from september 5, 2001 through may 19, 2005.

What 2004 Land Rover Discovery owners say
Most recent owner complaints, unedited.
Seems as if either the brake booster or a part of the braking system is not providing ample stopping power. The vehicle has a difficult time stooping in a hard braking scenario either from highway speeds or from a complete stop at a stop sign when we realized a vehicle was coming and had to slam on the brakes the vehicle did not stop as it should have. I have heard of this being an issue and thought there was already a recall but your website says otherwise.
Tl* the contact owns a 2006 (na) land rover discovery. The contact took the vehicle to the dealer for a windshield replacement. Upon retrieving the vehicle, the contact noticed a crack in the dashboard. The dealer diagnosed that the damage was due to the sun. The vehicle was not repaired. The manufacturer was notified of the issue. The failure mileage was 37,000.
The rear drive shaft fell apart at low speed. It would have been deadly at high speed
Cpsc: i1540160a. 2004 landrover discovery. Consumer stated the engine bay fuse box spontaneously combusted.
While driving, power to the air conditioner blower fan shut off. Upon parking 2 miles later, smoke began billowing from the hood. The under hood fuse/relay box appears to have shorted and caught fire. Visible damage is isolated to the fuse/relay box.
Engine failure.
I purchased our land rover 6 months ago I bought it with 105000 miles on it and financed it that way ,on january 17 th my wife got in the vehicle and it shows 186000 miles on the vehicle. The previous owner fraudulently sold a vehicle that has bin tampered with and I need to find out how to pursue him?
Tl* the contact owns a 2004 land rover discovery. While driving at an unknown speed, the vehicle overheated and smoke emitted from the engine. The dealer stated that the engine and the ignition needed to be replaced. No repairs were made to the vehicle. The manufacturer was made aware of the failure. The failure mileage was 80,000.
Complete engine investigation done by dealership and third party to investigate ticking noise. Engine removed, replaced all bearings, cam bearings, new camshaft, lifters, timing chain and gears. Cycled through over 5 types of oils and additives. Further research indicates possible manufacturer issue occurring in 2004 models where cylinder liner is actually slipping. Dealership claims that liner slipping is not possible and other issues would be apparent. However, multiple issues are documented by other owners. Other service teams indicate that engine could fail but was known issue by manufacturer. All 2004's are out of warranty so this has become a non-reported issue.
