“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…”

“Had engine cooling system repaired at dealer in 2023. In late 2024/early 2025 - engine coolant loss returned. We maintained engine coolant at recommended levels until we could get vehicle into dealership for diagnosis and repair. During routine local trip, low coolant light suddenly came on and immediately following that, engine stopped in the middle of traffic. Wife was barely able to navigate vehicle to safe place alongside the road. Vehicle was towed to dealer. They diagnosed engine failure due to oil cooling system failure. We contacted JLR and they offered no solutions. This is a $40,000 repair on a vehicle worth at most $20 to $25,000 retail. We had to dispose of it to a salvage buyer at an extreme loss.”

“This particular vehicle comes with a plastic coolant water outlet. When the plastic melts, it causes the coolant system to fail, and the engine will overheat. The plastic can only withstand heat up to 200 degrees Fahrenheit. Most engines run at 195-220. There was no reason for the manufacturer to use this type of plastic. Over 1,000 aftermarket coolant water outlets have been sold as a replacement for the manufacturer's part. There is a class action lawsuit for the faulty coolant water outlet. [XXX] v. Tata Motors Group, Jaguar Land Rover Limited, and Jaguar Land Rover North America LLC.”

“Upper and lower hoses that the Antifreeze travels through disconnected while driving on the highway due to the dipping in the roadway. Not enough play in the hoses to accommodate the stretching and pulling on the hoses while the car goes up and down resulting in the hose’s disconnecting and losing antifreeze and the engine shutting down. It happened to me 2 times in a matter of 3 weeks resulting in this dangerous situation.”
