2018 Land Rover Discovery Electrical Problems

Shortly after I purchased this used 2018 Land Rover Discovery with approximately 30,700 miles, the vehicle began intermittently lurching, surging and shaking during normal driving. These symptoms began before the check-engine light illuminated. Two days after the check-engine light first appeared, the lurching and surging became noticeably worse. Approximately two minutes before the first engine shutdown, numerous warnings appeared in rapid succession, including “Stability Control Not Available,” “Forward Alert Not Available,” “AEB Not Available,” and “ATPC Not Available.” I stopped the vehicle briefly. Approximately one minute after resuming driving, the engine unexpectedly shut off and the vehicle remained disabled for approximately 30 seconds before restarting. The abrupt loss of propulsion nearly caused the vehicle behind me to collide with the rear of my vehicle. During the second incident, the engine suddenly shut off while I was making a left turn through a four-way intersection. The vehicle became immobilized in the middle of the intersection, directly exposed to opposing oncoming traffic, and would not restart for approximately one minute. The sudden loss of propulsion mid-turn created an immediate risk of a serious collision. An independent OBD-II scan documented code P0456 simultaneously as stored, pending and permanent, as well as P0170 as a permanent diagnostic code. The selling dealership collected the vehicle because it could not safely be driven back, and the vehicle is currently available for inspection. There was no crash, fire or physical injury. I am reporting a potential safety defect involving repeated unexpected engine shutdown, loss of propulsion and multiple simultaneous system failures.

This vehicle has an active water intrusion from the headliner above the windshield due to windshield bonding and body seal failure. Water is dripping down and entering the dashboard area and shorting electrical control modules behind the media/glove box and media console. Each time the media/glove box is opened, the HVAC system shorts and forces the defrost system to activate involuntarily. The vehicle also exhibits Park Brake Fault warnings, delayed and intermittent no-start conditions, brake fluid loss, and electrical instability. This is an active electrical short inside federally regulated safety systems, making the vehicle unsafe to operate. The defect is progressive and continues to worsen

Water began leaking into car from front windshield while driving on 11/25/2025. Air whistling noises present also. Safety risk of injury from windshield failure. Repair person says risk for windshield coming off when driving or if involved in collision. Possibly related to recall N221 Land Rover Discovery SE 2018. Had Koch 33 perform assessment and they reproduced water and air leak and determined windshield is loose and not adhered. Erie Insurance says not covered and it is "wear and tear." No warning lamps or other symptoms prior to failure. Fearful of windshield coming loose/off if involved in crash and fearful that the water may be affecting the electrical system of internal lights and sunroof/moonroof. Available for inspection upon request.

Car went black (all systems shut off) and i started to roll in the CVS parking lot when i was trying to drive in and Park. The brakes and nothing was engaging. IT happened so fast I was able to stop the vehicle and I am not sure how but may have just turned the shifter from drive to park... I took the vehicle in for service (a number of issues) and i forgot to mention this, I was told the Ground Stud needed replacing and it turned out this was likely the cause (I believe he said it had come loose). I have a extended warranty that has comprehensive coverage with CNA and they denied this part. Also, Land Rover recalled this exact part on 2019 and 2020 vehicles, clearly my 2018 has the same issue. Makes me wonder how many other 2018 vehicles also have the issue?

THE KEY FOB IS CONSISTENTLY HAS ISSUES WITH STARTING THE VEHICLE. KEY WILL NOT UNLOCK DOORS WHEN TOUCHING THE HANDLE. VEHICLE WILL NOT START WHEN PARKED. THIS IS UNSAFE BECAUSE I HAVE BEEN STRANDED IN PUBLIC PLACES IN THE COLD AND THE VEHICLE WOULD NOT START. THE DEALERSHIP WAS ACTUALLY NO ASSISTANCE. CHANGING BATTERS DID NOT WORK. REPROGRAMMING KEYS DID NOT WORK. THEY PROMISED TO ORDER A NEW KEY FOB, AND THEN THEY SAID IT WAS BACKORDERED. I FELT LIKE THIS IS A LIE. THEY HAVE STRUNG ME ALONG WITH NO RESOLUTION. I HAVE PROVIDED FOUR SERVICE RECORDS TO SHOW THE AMOUNT OF TIMES THE VEHICLE WAS TAKEN INTO THE DEALERSHIP ABOUT THE VEHICLE NOT STARTING FROM KEY FOB NOT BEING RECOGNIZED.
