Land Rover Discovery overheating problems

Filed Mar 26, 2025 · Body, Engine · CO

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While sitting in park at idle RPM I heard a loud thump from the engine compartment which was followed by an electrical system warning and an engine overheat warning. I turned off the vehicle immediately and had vehicle towed to my mechanic. When care arrived at mechanics shop the crankshaft pulley literally fell off the car. Upon inspection the crankshaft pulley experienced a complete failure that resulted in total destruction of the engine. Entire engine needs to be replaced due to extensive valve/engine damage.

1.) water pump failed at 21,000 miles causing coolant to leak into the engine and the engine to overheat. 1 year later cylinder #1 lost compression in the engine making the car inoperable at 58,000 miles. Dealer indicates that the only possible repair option is a new engine at the cost of $21k even though they have no idea what is actually broken in the cylinder. Three independent mechanics have all indicated that the water pump is the most likely cause of the fault in the cylinder as it more than likely cracked a cylinder head when the coolant was leaking. My car failed with no warning while making a left hand turn onto a busy street, making this a very dangerous situation. 2.) the internal computer system failed on the car, which would notify the driver regarding service, engine temperatures along with any failures in the car's systems. Dealership used boilerplate paperwork to cover up that the system was not working twice. On the paperwork it specifically states that the "service interval reminders" were reset. I now know it would have been impossible for them to update this as the june 2017 paperwork shows where land rover implemented a fix for "messages - not appearing in the service cluster." land rover knew this for over a year and didn't notify their customers making it impossible for them to know that service reminders and sensors had failed on the vehicle resulting in missed maintenance because the car's operating system had failed. The end result being land rover is denying all responsibility for any issues that were caused by the computer system malfunction. The technology is over a decade old and is a standard expectation on today's cars. If land rover had notified their customers with a recall notice as soon as they became aware of the system failure, then there would be no fight regarding the coverage for my engine.

As a result of chaffing of a cruise control wire, the steering wheel rotary coupler can overheat and inadvertently deploy the driver's air bag....this has not happened yet to me, but despite my vehicle being a 1996 land rover discovery with only one previous owner, dealer claims my VIN# is not included in recall for substantiated by previous complaints submitted for this issue with my year/make/model, so please re-open investigation of the federal safety agency campaign # 98v040000 to include all 1996 land rover discovery VIN#s so it can be addressed before it deploys improperly. Deployment of the air bag restraint system without warning can cause a driver to lose vehicle control.
