While driving my 2022 Land Rover Defender 110 (16,658 miles), the brake pedal suddenly went soft and sank to the floor. Braking became severely degraded and effectively useless. I was able to slow the vehicle using engine braking and bring it to a stop safely. Multiple warnings appeared simultaneously, including brake system warnings, amber ABS and DSC lamps, and a "stability control not available" message. There was no crash, fire, or injury, but the loss of braking created a serious risk to me and the surrounding traffic as I was making a left onto [XXX] against oncoming traffic on [XXX] The vehicle was not driven further and was taken to an authorized Land Rover dealership for diagnosis. The dealership's diagnostic scan confirmed DTC C055E-7A ("Brake Hydraulic Circuit A Leak – Fluid Leak or Seal Failure") logged on XXX, along with related code C055E-64. This confirms a hydraulic fluid leak or seal failure in the service brake system, consistent with the total loss of pedal pressure I experienced. The manufacturer has issued Special Service Message SSM 74988 addressing this exact DTC on this platform (Defender L663, 2020 model year onward), indicating awareness of this failure mode. There were no warning lamps or symptoms prior to the failure — it occurred suddenly with no advance indication. The vehicle and diagnostic records are available for inspection upon request. Root-cause diagnosis by the dealership is in progress; the suspected sources are a hydraulic line, caliper, seal failure, or the integrated brake unit (which combines the booster, master cylinder, ABS pump, and control module in a single assembly on this platform). A sudden hydraulic brake failure at this low mileage suggests a potential defect rather than wear. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Bulletin 76096 should be recall. The suspension has failed. Both Upper arms, bushings,sway bars and links and after 3 weeks, multiple attempts to correct banging, the issue is a bulletin, but yet a recall, conveniently not under warranty. Only 50,000 miles. Please press for recall. Like the DC CONVERTER -impairing vehicle.

The windshield on my Land Rover Defender cracked from a tiny pebble. I sealed the crack but I'm just waiting for it to crack again. My friend [XXX] has the same car and he's on his fourth windshield. When I purchased the car, the sales person recommended the extended warranty because "the windshield is $3000 and you'll use it".

LAdder broke with me on it. I am 190 lbs. Well below what it is rated for. Both ladder hinges snapped with me falling on the ground as a result. Very painful. Informed LR and my dealer. No action taken.
