2015-2026 Lexus NX Problems: 18 Known Issues

The airbag pressure sensors and acceleration sensors used to detect a crash event can fail. When they do, the side and curtain shield airbags and/or the front airbags will not deploy in a collision that warrants them. The failure is silent in normal driving — nothing tells the owner that crash protection is gone. NHTSA campaign 18V085000 covers 2015-2016 NX 200t, NX Turbo, and NX 300h alongside 2016 Toyota Prius and Lexus RX 350 and RX 450h variants. The recall was expected to begin March 12, 2018, and Toyota's campaign numbers are JLA and J0F. The remedy is limited by sensor serial number, so the dealer inspects before replacing.

An electrical connection inside the steering column's spiral cable assembly — the coiled ribbon that carries signals to the rotating steering wheel — may be insufficiently welded. The connection can separate in service, which deactivates the driver's frontal airbag and puts the vehicle out of compliance with FMVSS 208, Occupant Crash Protection. Critically, campaign 25V040000 targets vehicles that may have been incorrectly repaired under the earlier recall 23V-480, so a car whose records show that prior repair is not necessarily safe. Owner letters were mailed March 17, 2025; the Lexus campaign number is 25LA02.

On NX vehicles equipped with the Panoramic View Monitor system, a software error can make the rearview camera freeze on a stale image or display a blank screen when the vehicle is shifted into reverse. A frozen image is arguably worse than a blank one, because it shows the driver a plausible but out-of-date view of what is behind the vehicle. Either way the vehicle fails to comply with FMVSS 111, Rear Visibility. NHTSA campaign 25V744000 covers 2022-2026 Toyota, Lexus, and Subaru Solterra vehicles with the PVM system; owner letters were mailed January 2, 2026, and the Lexus campaign number is 25LB06.

The rearview camera image may fail to display when the vehicle is placed in reverse, leaving the driver without the rear view the vehicle is required to provide and putting the car out of compliance with FMVSS 111, Rear Visibility. This is a separate defect from the Panoramic View Monitor software fault covered by campaign 25V744000, and the remedy differs: here the dealer updates the rearview camera software or replaces the camera itself, depending on what the inspection finds. NHTSA campaign 26V162000 covers 2022-2025 NX350 and NX250 along with 2023-2026 RX350 and 2024-2026 TX350. Owner letters were mailed May 15, 2026.

A Skid Control ECU software defect on 2022 Lexus NX vehicles leaves the Vehicle Stability Control system switched off after an ignition cycle if the driver had previously disabled VSC. Normally VSC re-arms automatically at every restart precisely because drivers forget they turned it off. With this defect, if the driver turns VSC off and then switches the ignition off and back on while keeping the brake pedal continuously pressed, the car restarts with stability control still disabled; a warning light does illuminate, but a driver who misses it believes the electronic safety net is active when it is not. The risk is highest in exactly the conditions the NX is bought for - wet or snowy roads - because the failure goes unnoticed unless the driver catches the warning light before the vehicle actually loses traction. This campaign was filed the same day as the spot-weld recall (22V238000) but is a completely separate defect with a separate remedy, and on the NX it covers only the NX 350h hybrid and NX 450h+ plug-in hybrid, not the gasoline NX 250 and NX 350.

On 2022 Lexus NX 250 and NX 350 models, the Skid Control ECU inside the Brake Actuator Assembly can falsely detect an overcurrent condition at the Electronic Parking Brake actuator and drop into a failsafe mode. In that state the EPB will not engage. Because the AZ20 NX has no mechanical handbrake lever - the parking brake is entirely electronic - the driver loses the only parking brake the vehicle has, and a car left on a grade can roll away. This is a software/logic calibration fault in the brake ECU, not a worn caliper motor, so it can strike a low-mileage vehicle without warning. Note this campaign covers the gasoline-only NX 250 and NX 350; it is a distinct campaign from the hybrid-specific brake and stability actions on the same platform, so confirm the VIN rather than assuming it applies to an NX 350h or 450h+.

Approximately 3,000 first-model-year 2015 Lexus NX 200t vehicles built between December 18, 2014 and February 2, 2015 left the plant with an internal component of the ABS actuator damaged during assembly. The damaged actuator may not modulate brake pressure correctly. Under some driving conditions, when ABS actually activates, the malfunctioning actuator can cause a loss of vehicle stability rather than preventing one - the system fails exactly when it is being asked to work. This is a launch-period assembly defect confined to a narrow production window at the very start of AZ10 production; it does not apply to the later 2016-2021 NX 200t/NX 300 or to the NX 300h hybrid, which uses a different brake actuator architecture.

The NX 450h+ plug-in hybrid uses a DC-DC converter to step the high-voltage traction pack down to the 12-volt system. A supplier damaged the electric current rectifying module inside that converter during production, and the damaged module can short circuit. When it does, current from the 12-volt battery keeps flowing through the shorted module and generates enough heat to damage components outside the converter housing and create a fire risk. Toyota's interim guidance was unusually specific: owners were told not to charge the vehicle when ambient temperature was at or expected to fall below 41F (5C). The campaign spans the RAV4 Prime and the NX 450h+ together (43,442 vehicles across both), with the NX share being a small fraction. This is strictly a PHEV issue - the NX 250, NX 350 and NX 350h do not have this converter and are not covered.

Second-generation NX owners across the NX 250, NX 350, NX 350h and NX 450h+ report the 12-volt battery going flat after the vehicle sits for a few days, sometimes on cars only months old. The pattern owners and dealer service writers describe is that the Lexus connected-services app repeatedly polls the vehicle, which wakes the DCM and downstream ECUs while the car is asleep, so the 12-volt battery never fully rests. On the AZ20 the consequence is worse than a normal no-start because the NX uses an electronic door release: with a dead 12-volt battery the car can lock occupants out or in until the mechanical override is used. A second, separate contributor is that the 12-volt battery is not charged in ACC/Aux mode on the hybrids - only in READY - so owners who sit listening to the audio system with the car on but not in READY drain the battery without realizing it. This is an owner-documented pattern with dealer acknowledgement, not an NHTSA recall; no US safety campaign covers it.

The first-generation NX infotainment system with the Remote Touch Interface touchpad suffers from significant lag and poor usability. The touchpad is difficult to control precisely while driving, and the system responds slowly to inputs. Menu navigation and destination entry are frustratingly cumbersome compared to touchscreen competitors.

Certain early-build 2022 Lexus NX vehicles (AZ20, all four powertrains) left the plant with spot-welds omitted between body panels in the front shock absorber mounting area. Toyota's filing states that with welds missing, the remaining welds and surrounding sheet metal can weaken and crack over time, and the front shock absorber can ultimately separate from its mounting point, causing an abrupt loss of vehicle control. Roughly 4,215 units were recalled and Lexus estimated fewer than 1% actually had the defect, but the failure mode is a structural one on a brand-new platform. Lexus also placed a sales hold on affected dealer inventory. This is an assembly-line escape on the very first AZ20 production run, not a wear item, so it will not appear as a gradual complaint pattern - it presents suddenly as a clunk or handling change from the front corner.

The low-pressure fuel pump inside the fuel tank can fail, cutting fuel supply and stalling the engine — potentially at speed and in traffic. This is the same Denso low-density impeller family of failures that ran across a very large number of Toyota and Lexus products, in which the impeller absorbs fuel, swells, and binds in the pump housing. NHTSA campaign 25V028000 covers 2019 Lexus NX300 alongside the 2018 Camry and 2019 RX350L. Owner notification letters were mailed March 12, 2025, and the campaign numbers are 25LA01 for Lexus and 25TA01 for Toyota. The remedy is replacement of the fuel pump assembly.

The sunroof drain tubes that carry water from the sunroof tray down through the A-pillars, and the cowl drains below the windshield, block with debris, and once blocked the water backs up and enters the cabin at the driver's side kick panel. Owners describe finding the driver footwell carpet soaked, often after the leak has been running unnoticed for weeks behind the trim. The cost of ignoring it is disproportionate: carpet and underlay that stay wet grow mildew through the padding, and replacement quotes in the region of $2,600 have been reported once the contamination is established. The water also reaches connectors and modules low in the footwell, so electrical faults often accompany the leak.

The AZ20 NX introduced Lexus's e-Latch system, replacing the mechanical door handle with an electronic button that signals a motor in the latch assembly. Owners of 2022-2025 NX models report the exterior handle button becoming unresponsive, most commonly in freezing weather: water enters the handle assembly, freezes around the internal switch, and physically blocks it, so pressing the button does nothing and the door cannot be opened from outside. Failures also occur intermittently outside of cold weather from switch and wiring faults within the handle. The related occupant-egress concern is that on a vehicle with a flat 12-volt battery the electronic release is dead altogether, and the mechanical backup - pulling the interior handle a second time - is not obvious to most occupants or to a first responder. NHTSA has signaled it will look at rulemaking for electronic door handles and mandatory physical redundancy, but there is no US safety recall for the NX handle.

The second-generation NX 350h with the eCVT hybrid powertrain exhibits a droning noise and rubber band sensation during moderate acceleration. The CVT holds the engine at high RPM while vehicle speed increases gradually, creating a disconnected feeling between throttle input and vehicle response that many owners find unpleasant.

NX 350 owners report a pronounced clunk or harsh driveline engagement immediately after shifting out of Park into Drive or Reverse on the 8-speed automatic paired with the T24A-FTS 2.4 turbo. Some owners also describe having to press the brake pedal unusually hard before the shifter will move out of Park. No Lexus bulletin specifically for harsh engagement was found; the related shift-out-of-Park bulletin, L-SB-0051-23, reprograms the transmission floor shift assembly on 2022-2024 NX 250 and NX 350 that show a warning to apply the brake when shifting out of Park. It is worth separating this from the mechanical clunking some NX 350 owners describe from the brake system, which is a different complaint with a different cause. This applies to the gasoline turbo NX 350 with the geared 8-speed automatic; it does not apply to the NX 350h or NX 450h+, which use an eCVT and have no torque converter shift to be harsh.

The mechanical water pump on the 8AR-FTS 2.0L turbo develops a coolant leak from its shaft seal and weep hole. The early signs are a slow, unexplained drop in the coolant reservoir and a crusty pink or orange residue below the pump on the front of the engine. What makes this more than a routine water pump job on the NX is access: the turbocharger inlet tube runs directly over the pump and must come off first, and its flange nuts are frequently seized after years of heat cycling, which is where an otherwise straightforward repair turns into a broken-stud job. Owners who let the leak run long enough to lose meaningful coolant risk overheating a turbocharged engine, which is considerably less forgiving than a naturally aspirated one.

The 8AR-FTS 2.0 turbo in the NX 200t and NX 300 is a direct-injected engine, and Lexus direct-injection engines have a long-standing record of fouling intake valves with carbon because fuel never washes across the back of the valve. Lexus partially mitigated this on the 8AR-FTS with D-4S dual injection - a secondary set of port injectors that does spray the intake valves - which is why this engine is markedly better than a direct-injection-only design and why deposits show up later rather than early. It is not eliminated, however: an NX owner who posted valve photos at roughly 60,000 miles showed meaningful carbon accumulation on the intake valves, though other owners dispute how widespread this is, and the symptom set is the classic one - rough cold idle, misfires, hesitation and a check engine light. Buyers of higher-mileage AZ10 NX 200t/300 cars should treat this as an inspection item, not an assumption of failure. This is specific to the 8AR-FTS; the NX 300h hybrid's 2AR-FXE and the second-generation engines are not the same case.
