2018 Land Rover Discovery Sport Problems

Ever since I bought the car back in April 2022, it has been in the dealer for intermittent check engine lights due to problems with the engine and transmission. The car would go on a limp mode especially when driving on a highway at steady speed. It would rattle, slow down or will not accelerate even when pressing the gas. This happened to me multiple times and it’s a major safety concern. After multiple attempts at repairing and installing a new engine and transmission, the issue has not been fixed. This is the only car I have and I am not able to drive it reliably and at full capacity due to fear of malfunction again. The incident report date is only the latest date of the repair. The repairs have started back in 2023.

while driving the vehicle goes from drive to neutural or D to N... without me changing it

I continue to have an intermittent issue with my car throwing itself into park. It happened once in 2024, 2025 but now three times in the last two weeks. This is becoming incredibly unsafe as while driving the car puts itself into park while in motion. The insurance company will not repair due to it being intermittent. I do not know what to do but I need this documented for safety reasons

While driving approximately 30 mph in June 2024, my 2018 Land Rover Discovery Sport unexpectedly displayed Gearbox Fault and Brake Fault warnings and shifted itself into Park while the vehicle was moving. The vehicle became immobilized in the roadway and could not be shifted out of Park for an extended period. The identical failure occurred again in July 2025 and July 2026. During the 2025 and 2026 events, the vehicle again became locked in Park and left me stranded. During the 2026 incident, the failure occurred twice within approximately fifteen minutes, and each event required approximately thirty minutes of repeatedly applying the brake pedal and cycling the electronic parking brake before the transmission would release. Land Rover dealerships have recovered transmission diagnostic trouble codes, including P099B-14 (Shift Solenoid G Control Circuit Low), and have repeatedly diagnosed the likely cause as an internal transmission valve body and/or internal transmission wiring harness failure. The Warranty Company - Fidelity Warranty Services (Carmax) has consistently refused to cover the repair of this vehicle stating that it must be replicated in front of the warranty technician. This is an intermittent issue which means it can not be replicated on demand. Instead of working with me, they continue to have me drive a vehicle which can put me and others at risk This failure has now occurred over three consecutive years and creates a significant safety concern because the vehicle can unexpectedly become immobilized and lose propulsion. I am submitting this complaint because I believe this may represent a recurring safety defect.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced repeated electrical, ignition, and safety‑system malfunctions, including failure to start, intermittent power loss, stalling, battery failure, and irregular electronic behavior. Multiple components appeared affected, including the ignition system, battery/charging system, electrical wiring, and onboard diagnostic/electronic control systems. The vehicle is available for inspection upon request, and police reports and repair documentation exist confirming ongoing issues. --- 2. How was your safety or the safety of others put at risk? The vehicle became unreliable and unsafe to operate, with unpredictable starting, stalling, and electrical failures that could occur at any time. These defects created a risk of: • Being stranded in unsafe locations • Sudden loss of power while driving • Inability to start the vehicle during emergencies • Exposure to repeated dangerous situations for both myself and my child The ongoing defects directly compromised the vehicle’s safety and my ability to use it for normal transportation. --- 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issues were repeatedly reported and observed during multiple repair attempts. Despite this, the dealership and service centers failed to correct the defects, and the problems continued after each visit. --- 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Yes. • Police reports were filed documenting incidents related to the vehicle’s malfunctioning. • Insurance representatives were involved following the accidents and repair disputes. • Dealership technicians inspected the vehicle multiple times but did not resolve the underlying defects.

Vehicle was driving down the highway in early April of 2025 when the engine showed a sudden loss of power and diminished performance with misfires and rough running. Thankfully I was able to pull to the side of the highway before automobiles behind me rear-ended the vehicle after such a sudden loss in driving speed. it was later determined that at roughly 56,000 miles, the automobile suffered a cracked intake valve on cylinder 2, which fell into the engine. The recommendation was a complete engine replacement after the diagnosis was done by an authorized Land Rover service center. This occurred roughly 13k miles after the vehicle was serviced for persistent misfires and rough idling. The CVVL unit and PCV Assembly parts were replaced at that time.

My parents are [XXX] . They were coming home from there doctors appointment on [XXX] and traveling about 50 MPH heading home and all the sudden my father tried to press on the brakes to slow down and there was no brakes at all. He could not stop the vehicle and the ONLY thing that saved his and my moms life was the fact that the 2018 Land Rover discovery sport SE came to a hill and immediately as soon as the vehicle came up the hill my father turned the wheel to the right and the vehicle stopped after hitting one of those parking lot cement blocks right in front of a mechanic shop. When my parents got out of the vehicle they were so shook and scared for their life. A mechanic came out to ask if they were ok and they explained to the mechanic what had happened. The mechanic then, pushed the vehicle inside the garage and put it up on a lift and diagnosed it and then told my parents that the brake lines had blown and that it was unusual and that this was a manufacture problem and Land Rover needed to be contacted or for us to go online under this website and file a complaint. We may have to retain an attorney because my parents only bought this vehicle less then a year ago and already almost lost both of their lives due to the brakes going out and brake lines bursting.

I was driving and the vehicle car stalled it said gear box defect and switched from reverse to drive to neutral but would not move. I think this is dangerous since my car was already in drive and suddenly stalling could've caused an accident. Luckily there was no car behind me or it would have rear ended me.
