My vehicle started losing power and I attempted to accelerate but the SUV stopped moving. My girlfriend immediately put on the hazard ⚠️ lights because a tractor trailer truck was coming up from behind us. I was able to coast over to the shoulder.

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.

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.

Driving down the highway, the vehicle all the sudden started smoking, forcing me to pull over. Upon pulling over, I found it was a fire under the left front hood based on the smoke pouring out. I called 911 immediately. I attempted to save some belongings, including my $200K boat, but failed to save anything as the fire rapidly grew forcing me to step far away. I then watched my car, boat and belongings all perish to nearly nothing before the fire department arrived and put out the fire. While I am lucky to be safe and have adequate insurance, others may not fair so well when their Land Rover Discovery 5 petrol catches fire.

I was driving on a very busy road in Portland when my engine suffered catastrophic failure and seized the engine. This was due to a defect in the crankshaft. My family and I are lucky this didn’t happen at speed on a highway. Land Rover has failed to acknowledge a problem despite thousands of people experiencing the same. This resulted in a 26k bill. I just found out I could report my experience so I am now. Research has uncovered this is a common problem and a safety concern for many others as well. https://www.thepetitionsite.com/535/903/886/land-rover-sdv6-amp-tdv6-crank-failure/ https://www.lrukforums.com/threads/crank-shaft-snapping.263315/ There are countless other websites detailing people’s experiences.

was driving on Wa-18 highway going to Snowqualmie Falls with my family. Suddenly I heard a snap from the front and at the same moment the car start shaking from the front so I slowed down trying to go to the right lane so I could stop when i see a chance because I was in an area where there is no emergency curve. The car died couple of seconds after the snap and because the cars were going too fast on the right lane i ended up in the left lane then I saw car Fumes coming from the engine area but I couldn’t exit the car for safety and made sure that I turned off the ignition and was hoping that the car will not go up in flames while im on a freeway and have my wife and my 3 kids in the car with me. A lot of traffic buildup behind me and minutes later the state patrol pushed me to the next exit. I called AAA and towed the car to Land Rover Of Tacoma for an inspection. After they inspected the car, they said that the timing chain was loose and the car need a new engine. At six years old only a car with 65,000 miles not supposed to have a problem with the timing chain. The dealership failed to tell me what’s the reason that the time in chain is loose because this time in chain supposed to last for a longer than 65,000 miles with no problems. I read all over the Internet and everyone is complaining about the Land Rover timing chain brake or get loose with low mileage and many of these people say the car went off on the freeway and put them on a dangerous situation just like what happened with me and my family.
