The failure pattern owners describe
Water pooling is the dominant complaint. Sunroof drain tubes get clogged, allowing water to accumulate up to 3 inches deep on driver and passenger floors after heavy rain, then seep through A-pillar airbag ports and interior light consoles. Owners report this flooding recurring multiple times—up to five instances—even after dealers claim to have fixed the drains by installing larger-diameter tubes.
The water causes cascading electrical damage. Remote keyless entry systems fail most frequently, unable to lock or unlock doors days after rain. Parking brake control circuits fail and warning lights stay on. One owner's parking brake was never repaired despite multiple subsequent flooding events. Electrical wiring corrodes from sustained moisture, leading to short circuits and mold colonization in carpet and padding. Carpet removal and treatment with Lysol have been the remedy; at least one family reported bronchial problems lasting three months afterward.
Beyond water intrusion, owners report serious engine and electrical faults: random stalling when fuel dips below one-quarter tank (unresolved by dealer), all dashboard warning lights illuminating simultaneously with power steering failure and engine surging (attributed vaguely to "onboard computer system"), a battery explosion at highway speed, and intermittent multifunction warnings that clear on restart. Dealers consistently provide no clear diagnosis or lasting fix for non-water-related failures.
Failure modes owners describe
Sunroof and windshield water intrusion leading to electrical failure
Water enters the vehicle through clogged or improperly sealed sunroof and windshield drains, traveling down the A-pillar frames and into the interior. Pooling water—up to 3 inches deep reported—damages electrical wiring and causes corrosion, mold growth, and short circuits in multiple vehicle systems.
When: After heavy rain; some owners report repeated flooding (up to 5 times) despite dealer repairs
Symptoms owners cite: Water pooling on driver and passenger-side floors; Water dripping from windshield frame area and A-pillar airbag ports; Mold growth in carpeting and floor mats; Water damage to interior carpeting and cabling
Repairs/costs cited: Dealers replaced clogged drain tubes with larger diameter ones; carpet removal, Lysol treatment, and recarpeting performed. Electrical wiring repaired on a system-by-system basis as failures appeared; no comprehensive rewiring noted.
Keyless entry remote failure due to water-induced corrosion
Remote lock/unlock system fails intermittently or completely after water intrusion from sunroof drains causes electrical wiring corrosion and short circuits. Owners report this as a documented, widespread issue for the model year.
When: Days to weeks after heavy rain events
Symptoms owners cite: Remote key fob unable to lock or unlock doors; Intermittent remote operation that resolves after water evaporates; Both remote controls failing simultaneously
Repairs/costs cited: Remote control systems repaired after water damage inspection; no preventive treatment of underlying corrosion noted
Recalls/TSBs owners mention: Dealers acknowledged the problem as common but stated it does not warrant a recall
Parking brake failure and warning light malfunction
Parking brake becomes inoperative and the warning light illuminates, triggered by water damage to brake control wiring. One owner reported the brake was never repaired and multiple flooding incidents occurred afterward.
When: Days after heavy rain and water intrusion
Symptoms owners cite: Parking brake does not engage; Parking brake warning light illuminates; Brake remained inoperative despite dealer claim of drain repair
Repairs/costs cited: Not repaired in at least one reported case; owner notes brake failure persisted through multiple subsequent flooding events
Engine stalling under low fuel conditions
Vehicle stalls randomly when fuel level drops below one quarter tank, accompanied by flashing check engine warning light. Failure occurs repeatedly and can happen at highway speeds. Diagnosis unclear; VIN not covered under related fuel system recall campaigns.
When: Approximately 80,060 miles; when fuel tank is lower than 1/4 full
Symptoms owners cite: Check engine warning light flashes and remains illuminated; Vehicle stalls without warning while driving; Stalling repeats intermittently; Stalling occurs specifically when fuel is below 1/4 tank
Repairs/costs cited: Vehicle taken to repair shop for inspection and diagnosis; manufacturer provided no remedy
Recalls/TSBs owners mention: Manufacturer notified but provided no remedy. VIN was not included in NHTSA campaigns 07V011000 and 05V376000 (fuel system)
Onboard computer system failure causing loss of power steering and engine surging
All warning lights illuminate on the instrument panel simultaneously; power steering cuts out and engine revs uncontrollably. Failure attributed to onboard computer system malfunction. Dealer unable to diagnose or remedy; claims problem already corrected despite repeated recurrence.
When: At approximately 10 miles; current mileage 32,000
Symptoms owners cite: All warning indicator lights illuminate simultaneously; Power steering fails; Engine revs; Failure occurs repeatedly; dealer claims correction without actual repair
Repairs/costs cited: Dealer stated failure was caused by onboard computer system but did not repair the vehicle
Battery explosion
Battery explodes while vehicle is being driven at 40 mph. Dealer attributes failure to faulty battery. Explosion causes significant damage to vehicle and results in total loss of use for three months.
When: At 57,659 miles
Symptoms owners cite: Battery explosion while driving
Repairs/costs cited: Battery was replaced; total damages of $11,252.34 documented, including car rental, loss of vehicle for 3 months, and vehicle damage repair
Recalls/TSBs owners mention: Dealer stated battery was faulty
Bent electrical connector causing stalling
Vehicle stalls at 60 mph while driving. Dealership inspection reveals a bent connector failing to make proper electrical contact. Repair of the connector resolves the stalling.
When: During the complaint period; no additional mileage noted
Symptoms owners cite: Vehicle stalls at 60 mph while driving
Repairs/costs cited: Bent connector repaired; no further problems reported after repair
Multiple electrical warning lights and system intermittent faults
Multiple warning lights illuminate simultaneously on instrument panel, including suspension and parking brake warnings, along with HDC (Hill Descent Control) failure display. Symptoms resolve after engine restart, suggesting an electrical transient or computer glitch.
When: Intermittent; occurs after starting vehicle
Symptoms owners cite: Multiple warning lights illuminate simultaneously; Suspension fails to inflate to normal height; Parking brake warning remains on; HDC failure message displayed; All symptoms resolve after vehicle restart
Repairs/costs cited: No repair documented; symptoms resolve with vehicle restart

I just bought a 2005 land rover lr3 se. Two days later after a rain, the passenger's side floor was wet. The next day the remote keyless entry stopped working. After looking online, I found that this is a common problem with the keyless entry due to a problem with the sunroof drains pouring water into the floor and causing corrosion of the wiring. *tr
