2019 Land Rover Discovery Sport

The ZF 9HP48 9-speed automatic transmission is the Discovery Sport's weakest link. Owners report harsh shifts, jerking during low-speed maneuvers, hesitation when merging onto highways, and confusion in gear selection under varying loads. The transmission may get stuck in a higher gear, leaving the engine lugging, or downshift too aggressively.

A transmission control module (TCM) software update improves shift calibration and adaptation logic. JLR has released multiple TCM updates since launch. A full transmission fluid drain and refill with ZF LifeGuard 9 fluid is also recommended. If internal clutch packs are worn, a transmission rebuild or replacement may be necessary.

The InControl Touch infotainment system freezes, lags, or reboots during use. Navigation freezes mid-route, Bluetooth connectivity drops, and the reversing camera becomes unavailable during screen resets. The system is slow to boot on cold starts and can take 30-60 seconds before becoming usable.

A software update to the latest firmware version is the first step. If the infotainment head unit has a failing internal storage drive, the entire module must be replaced. JLR TSB LTB00638 addresses infotainment stability improvements for the L550 platform.

The panoramic glass roof drain tubes become clogged with debris, causing water to overflow into the headliner and drip onto the front and rear seats. In severe cases, water accumulates in the rear footwells and damages carpet underlayment and electrical connectors beneath the seats. The issue is widespread and affects a large number of Discovery Sports.

Clear the panoramic roof drain tubes using compressed air or a flexible cleaning tool at each corner of the roof. Replace the roof seal if it is cracked or compressed. In severe cases, the headliner must be removed to fully clean the drainage channels. This should be done as preventive maintenance annually.

The electronically controlled rear differential coupling (Haldex-type unit) fails, causing the AWD system to default to front-wheel drive only. A 'Driveline Fault' message appears, and the vehicle loses rear-axle power delivery. The coupling's hydraulic pump and filter can become contaminated if the fluid is not changed at the specified intervals.

Service the Haldex coupling with a fluid and filter change first. If the hydraulic pump has failed, the coupling unit must be replaced. The differential fluid should be changed every 30,000 miles as preventive maintenance. JLR TSB LTB00621 covers Haldex unit diagnosis and service.

The wiring harness that runs through the tailgate hinge area experiences fatigue and breakage from repeated opening and closing. This causes the rear wiper, license plate lights, rear camera, and tailgate release to stop working intermittently. Broken wires in the harness can also trigger body control module fault codes for unrelated systems.

Inspect the tailgate wiring harness at the hinge flex point for broken conductors. Individual wires can be repaired with proper splicing and protection. In severe cases, the entire tailgate harness must be replaced. The harness should be re-routed with additional slack and protection at the flex point.

Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2017-2020 Land Rover Discovery vehicles. The UniLatch Keyless Vehicle (KV) entry function may fail to properly latch the rear passenger doors, which can result in the doors opening while driving. In addition, the instrument cluster open-door warning light may fail to alert the driver of this condition.

Rear passenger doors that open while driving can increase the risk of a crash. An instrument cluster warning light that fails to alert the driver about unsecured doors can increase the risk of injury in the event of a crash.

Dealers will disable the UniLatch Keyless Vehicle (KV) entry function, free of charge. Owner notification letters were mailed July 26, 2023. Owners may contact Land Rover customer service at 1-800-637-6837. Land Rover's number for this recall is N798.

Jaguar Land Rover North America, LLC. (Land Rover) is recalling certain 2018-2020 Range Rover, Range Rover Sport, Discovery, and Range Rover Velar vehicles. The Auto High Beam (AHB) system does not indicate through the instrument cluster when the high beams are illuminated automatically. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

The driver may be unaware that the high beams are illuminated, reducing visibility for oncoming traffic, and increasing the risk of a crash.

Land Rover will notify owners, and dealers will update the vehicle software, free of charge. The recall began April 7, 2021. Owners may contact Land Rover customer service at 1-800-637-6837. Land Rover's number for this recall is N556.

Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2019-2020 Discovery vehicles. A loose contact between the battery ground stud and the chassis may result in various electrical faults, possibly causing a loss of electrical power or the vehicle to shut down while driving.

If the vehicle shuts down or loses exterior lighting while driving there could be an increased risk of a crash.

Land Rover will notify owners, and dealers will replace the ground stud, free of charge. The recall began December 17, 2020. Owners may contact Land Rover customer service at 1-800-369-1000. Land Rover's number for this recall is N400.

Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2019 Range Rover, Range Rover Sport, Range Rover Velar and Discovery vehicles. The affected vehicles are equipped with V6 or V8 engines whose crankshaft pulley retaining bolt may fracture possibly resulting in engine failure.

Engine failure can increase the risk of crash.

Land Rover has notified owners, and dealers will replace the crankshaft pulley center retaining bolt, free of charge. The recall began February 12, 2019. Owners may contact Land Rover customer service at 1-800-637-6837. Land Rover's number for this recall is N276.
