2024 Lexus RX Reliability Report

Owners of the 2024 Lexus RX report issues with the engine unexpectedly shutting off or revving loudly under certain conditions. Specifically, one complaint describes the engine or turbo turning off during slow acceleration, causing the vehicle to nose dive and then produce a loud sound upon restarting, which has led to near rear-end collisions. Another owner mentions the engine revving loudly when the gas pedal is released, creating a potential risk of the car not stopping properly. These issues reportedly occur at random intervals and have been noted after the vehicle has accumulated several thousand miles. Safety implications include the risk of collisions due to unexpected vehicle behavior.

Owners of the 2024 Lexus RX report issues with the automatic emergency braking system engaging unexpectedly. Complaints frequently mention the system activating violently and suddenly at low speeds, even when no obstacles are present. One owner describes the system engaging six times, including twice in the middle of the street without any apparent obstacles. Another owner reports similar incidents while reversing, where the system activated in a parking lot and during a u-turn in an empty lot, citing minor objects like a leaf or poor visibility conditions as potential triggers. These incidents occur shortly after purchase, suggesting they may arise early in the vehicle's use. The unexpected activation of the braking system poses potential safety risks, particularly in situations where sudden stops could lead to dangerous situations in traffic.

Owners report two distinct structural issues with the 2024 Lexus RX. One complaint describes the moonroof spontaneously shattering while driving on the freeway, which limits the vehicle's speed to less than 20 mph due to continued shattering at higher speeds. Another complaint involves the melting of the plastic trim between the driver's door and the rear passenger's door, suggesting a potential defect in the material's quality. These issues are reported without specific mileage details, and the moonroof incident may have safety implications due to the potential for driver distraction or debris entering the cabin. Buyers considering this model should be aware of these reported structural concerns.

Owners of the 2024 Lexus RX report issues related to the steering system, with two distinct problems noted. One complaint describes a clicking noise from the steering wheel and a shimmying sensation when braking, attributed to a failing tie rod at approximately 20,611 miles, which was resolved under warranty. Another report highlights potential concerns with the proactive driver assist system, which allegedly causes unexpected steering adjustments, leading to a severe crash with two injuries. This incident involved the vehicle swerving on a snow-covered road, raising potential safety implications for the driver assist feature. These reports suggest buyers should be vigilant about steering system performance and the behavior of driver assist technologies, especially in adverse weather conditions.

Owners of the 2024 Lexus RX report issues with the vehicle's visibility and wiper system. Complaints frequently mention the front windshield as being very fragile, with susceptibility to chips and cracks from small rocks, leading to impaired visibility due to glare from the sun. Additionally, one owner describes a failure of the wiper system during a rainstorm, where the wipers became stuck in the middle of the windshield, attributed to a defective motor, which posed a significant safety risk due to reduced visibility. These issues are reported shortly after purchase, suggesting they may occur at low mileage. Buyers should be aware of potential windshield fragility and wiper motor defects when considering this vehicle.

Owners report sudden unintended acceleration while attempting to park the 2024 Lexus RX, with both complaints describing this issue occurring approximately 20 feet behind another vehicle. The typical symptom includes the vehicle unexpectedly accelerating at a high speed, requiring the driver to apply the brake forcefully to prevent a collision. Both incidents did not result in a crash, as the vehicles were successfully stopped in time. The complaints do not specify mileage, suggesting this issue may not be related to vehicle age or wear. These reports highlight potential safety implications due to the unexpected nature of the acceleration and the need for immediate driver intervention to maintain control.
