2018 Land Rover Range Rover Sport Engine Problems

Coolant leak due to poorly made plastic part above the supercharger. High risk of fire and overheating due to land rover's poor design. OEM unwilling to help.

The engine coolant pipe cross over on top of the engine and the the one in the rear are made of plastic and is a known failure point. One simple search and it is known that its a super common problem that should be recalled and fixed. This is an engineering oversight and cost the car owner over $3000 in repairs if they are lucky to catch it before it destroys the engine.

Driving on interstate the coolant level low light went off and started blowing hot steam from underneath the hood the hood. Running 70 on the interstate and now couldn’t see due to the steam. I luckily maneuvered out of traffic and limped to exit. Very easily could have been a 10 car pile up. Got the car to a mechanic and it had a plastic quick connect on a hose break. There are no metal clamps as backup and the mechanic said that these run on very high water pressure and those plastic quick connect clamps are huge problems because they can’t hold the pressure with the slightest defect and there are no metal clamps to securely hold. I had the hose replaced. Speak to any Land Rover mechanic and you will immediately learn how many problems people are having with this issue. Seeing how many claims are made around the cooling system, plastic quick connectors, main hose under the supercharger causing so many issues with no warning, I pray someone looks in to this issue and makes Land Rover fix these issues. It is truly a miracle this did not cause a major accident.

Consistent coolant leak

In February 2024, my car overheated. There was a large coolant leak in valley from the water pump and outlet pipes and a secondary leak from rear crossover pipe as well. The water pump, water valve, and cooling hoses were replaced, as well as the failed outlet pip and cooling hoses. Coolant soaked belts were also replaced. In August 2024, my car overheated AGAIN. This time, while I was driving in the middle of the freeway. When I took it back, there was another leak from one of the cooling hoses, so it was replaced again. Just last week, my car overheated AGAIN. Again, it was another leaking component that was fixed under warranty. The auto shop I took it to reached out to the dealer, as it's been an issue well known for failure.

Engine failed at 43k miles. RR would not take apart engine to identify failure. Local RR repair shop (Elite Rovers) claims they see 3-4 dead RR engines per week usually between 60k-80k miles. He thinks it’s a coolant component failure that damages the engine. This many failures per week is not normal. There seems to be a class action lawsuit over engine failure in the UK and Australia—so this is not a small problem. My husband was driving the car when it happened and if on the freeway could have been seriously hurt. No warning, no engine light, no leaks…. Just locked up and died. 6 months later my neighbors RR engine also locked up and died. There are 6 dead engine RR at the dealer right now that people are abandoning because the cost to put a new engine in costs more than the value of the car or there are no engines available. Who can make JLR (manufacturer) take responsibility for this known issue that they are playing as if they dont know?

While driving on the freeway a low coolant notification came on. Minutes later we saw what we believed to be our engine in smoke. We made it to the side of the highway before the car became engulfed in steam. Car was towed to Land Rover Rancho Mirage. It was found that lower front coolant manifold had failed what caused the sudden release of steam. This caused engine to overheat and allow coolant to enter the lubrication jacket causing the oil to become contaminated resulting in full engine damage. The person we spoke with knew pretty quickly what happened. Online research shows this is a known problem with Land Rover Range Rover Sport and it has not been recalled. We were quoted 30K to replace engine. We got it replaced outside of dealership for 20K. This is a serious safety issue. I have videos of damage I can send in an email, it will not let me upload.

My family and I were driving home in my 2018 Range Rover Sport, which I purchased in 2019 from Land Rover of Sudbury (Massachusetts). A brief “coolant level low” warning flashed on the dashboard for less than a minute, then promptly went away and never flashed or displayed again. Minutes later, the car started shaking, forcing us to pull over onto the side of the Massachusetts Turnpike. The engine then immediately began smoking. The temperature gauge never went above the midpoint level, so we were quite confused about what the problem was. We had the car towed directly to Land Rover of Sudbury. They informed me that the engine needed to be replaced. I find it unacceptable, and most importantly, unsafe, that the car would go from a “Coolant Level Low” warning that lasted mere seconds before disappearing, to ZERO coolant and a catastrophic engine failure minutes later while driving on [XXX] This all happened only a few months after the vehicle had ostensibly been deemed to be in suitable repair by Land Rover of Sudbury upon my re-taking possession of it following 6+ months in their service shop. I still have not received any answer whatsoever from the dealership as to what went wrong with my vehicle. I have serious concerns that this could be evidence of a more pervasive issue that could potentially affect other vehicles that are currently on the road. I also question whether the service performed to the vehicle at Land Rover of Sudbury in 2023 was the cause of the issue. I question the sensors in the vehicle, as well as the communication to the dashboard, and I would like this fully investigated. Why would the coolant level low warning have gone off so quickly after it came on if there was NO coolant? Why would the temperature gauge on the dashboard not have elevated if the car was overheating? All of these questions lead me to the belief that something was wrong with the vehicle beyond what has been conveyed to me so far.

The contact owns a 2018 Land Rover Range Rover Sport. The contact stated that while operating the vehicle, the coolant warning light illuminated, and the engine temperature gauge started to fluctuate. The vehicle was taken to the local dealer who diagnosed that the coolant outlet pipe was faulty and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 70,000.

The engine overheating light came on followed by coolant level low. There was a rattling sound coming from underneath, the car slowed down, and smoke came into the air vents in the car and was smoking under the hood when pulled over. I took my vehicle to the closest dealership, Honda, to assess and determine if it needed to be towed to Land Rover or if they could fix it. The day prior the coolant level low light came on, my husband filled the coolant and the light went off. When I was driving my car the next day the light came on along with the engine overheating, something was dripping from underneath when the vehicle was turned off.

The contact owns a 2018 Land Rover Range Rover Sport. The contact stated that while driving approximately 65 MPH, the vehicle started to decelerate unintendedly. Additionally, there was a rattling sound present under the vehicle. The contact stated that the check engine warning light was briefly illuminated. After pulling over to the side roadway and parking the vehicle, the vehicle was towed to the local dealer to be diagnosed. The contact was informed that the engine rod bearing had failed and the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was not yet notified of the failure. The failure mileage was 36,000.

TL* THE CONTACT OWNS A 2018 LAND ROVER RANGE ROVER SPORT. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE SHUT OFF WITHOUT WARNING AND THE CHECK ENGINE INDICATOR ILLUMINATED. THE CONTACT TOOK THE VEHICLE TO LAND ROVER OF CHANTILLY (4120 AUTO PARK CIR, CHANTILLY, VA 20151, 703-679-4000) TO BE DIAGNOSED, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE VEHICLE WAS RETURNED TO THE CONTACT, BUT THE FAILURE PERSISTED. THE VEHICLE WAS TAKEN BACK TO THE DEALER TO BE SERVICED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 14,000.

THE 2018 MODEL HAS A SIGNIFICANT THROTTLE DELAY WHEN ACCELERATING THE CAR FROM A STOP, RESULTING IN DELAY IN MOVEMENT AFTER PRESSING THE ACCELERATOR PEDAL. THIS CAN BE VERY DANGEROUS WHEN TURNING ONTO BUSY ROADS AND WHEN ACCELERATING AT STOP SIGNS, AS IT TAKES 1-2 SECONDS BEFORE THE CAR REGISTERS THAT THE ACCELERATOR PEDAL HAS BEEN DEPRESSED, AND THEN JOLTS FORWARD AT A HIGH SPEED TO "CATCH UP". TWO LAND ROVER DEALERS (WEST CHESTER PA AND WAYNE PA) HAVE CONFIRMED THAT NUMEROUS CUSTOMERS HAVE COMPLAINED ABOUT THIS ISSUE BUT THEY HAVE NOT BEEN ABLE TO FIX IT AND HAVE BEEN RESEARCHING SOLUTIONS FOR MONTHS. THE SERVICE MANAGER IN WEST CHESTER PA CONFIRMED THAT ONE OF THEIR SERVICE TECHNICIANS, WHEN TESTING THIS ISSUE, WAS ALMOST HIT BY A MOVING CAR IN FRONT OF THE DEALERSHIP BECAUSE THE CAR HE WAS DRIVING DID NOT REACT SOON ENOUGH AFTER HE DEPRESSED THE ACCELERATION PEDAL. THE WAYNE PA SERVICE DEPT CONFIRMED THAT THERE IS 0.8 SECOND THROTTLE DELAY WHEN TESTING ANOTHER CAR (NOT MINE). I FORMERLY SUBMITTED A CASE TO LAND ROVER JAGUAR OF NORTH AMERICA BUT THEY HAVE NOT YET RESOLVED THIS ISSUE. THESE CARS SHOULD NOT BE ON THE ROAD WITH THIS ISSUE!
