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.

I am filing this complaint regarding a catastrophic engine failure on my 2017 Land Rover Discovery HSE Luxury with the 3.0L V6 supercharged engine. The failure was caused by a broken timing chain, which resulted in severe internal engine damage. This component failure has been confirmed by an independent Land Rover specialist, and the damaged parts — including the broken chain — are available for inspection upon request. The incident put our safety at risk, as the vehicle experienced sudden loss of engine power while in operation. A complete engine stall, especially in traffic or at highway speeds, could easily lead to loss of power steering and braking assistance, significantly increasing the chance of an accident. Prior to the failure, we noticed several warning signs, including an illuminated check engine light, rough idling, and multiple diagnostic trouble codes (DTCs), such as P0018, P0019, P0300, P0304, P0305, and P0306. These symptoms began appearing a few weeks before the engine failed completely, but escalated quickly. To our knowledge, there is no recall or technical service bulletin (TSB) addressing this known issue on this model and engine configuration. The vehicle has not yet been inspected by Land Rover, the police, or any insurance agency, but the independent mechanic confirmed that the failure was internal and directly related to the timing chain system. We are submitting this report in the interest of public safety, as this type of failure on a vehicle with regular maintenance and 140,000 miles should not occur without warning. We believe this may indicate a broader reliability issue with the timing system in these engines and urge the federal safety agency to investigate.
