Water coming from top part of the front windshield. This was previously fixed but after few years problem persists and started causing electrical issues. I already had to replaced computer out of my pocket even it was under warranty cause did not wanted to fix it.
Water leak front windshield passenger side. There has been a windscreen issue for the 2018 discovery faulty install. 2017 is the same vehicle and is having the same issue. This water can leak down into the dash a create electrical issues.
There is a safety recall for the 2019-2020 Land Rover Discovery models. 414-01 SAFETY RECALL: Startup Battery Ground Stud - Insufficient Ground Contact Land Rover Tech bulletin dated 09 DEC 2020 On July 25 my 2017 Land Rover discovery lost power, instrumentation went haywire, and steering limp as I was making a turn onto US-90. On August 5 it would not start. Eventually jump started it, as the battery did not seem to register to the vehicle. On August 6 it again lost power, drive train went limp, all warnings lit up, and steering died as I was getting onto I-95 On August 7 JLR of Jacksonville informed me they found arching burn marks on the battery ground stud. They knew this as a common issue from the previous Tech Bulletin. The 2017&2018 have the same design as the 2019&2020, why are the 2017&2018 not included in the recall?
Vehicle electronics began going crazy. The instrument cluster and gages just started flashing and pulsating. The transmission and mode selection cluster lit up like a Christmas tree. The engine power and steering went limp. The transmission eventually stuck in drive. This occurred twice while driving on the roadway. The second time I had it towed to the dealership. The dealership found the M6 ground stud to be arching. This same issue is a technical bulletin for the 2019-2020 models, but 2017-2018 which are of the same design and build were left off the recall.
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. 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)
