Dashboard melting — expired goodwill program
Sticky, visibility-impairing dashboard surface, toxic-fume concerns reported
Check engine light: Off
Lexus ran "Customer Support Program ZLZ" covering sticky/melting dashboards on this generation, but it expired in 2021. Since the coverage window has closed, this is now a genuine out-of-pocket common problem for current owners. NHTSA complaints describe toxic-fume concerns alongside the visibility impairment. A cosmetic/material fault like this doesn't trigger a check-engine light.

Battery / alternator issues
Dead battery, weak cold-crank amperage, poor charging
Check engine light: Off
Battery and alternator failures across a very wide mileage range, including battery drain after roughly 30 minutes of use in some reports. A charging-system fault typically shows as a battery light, not a check-engine light.
$150 – $1,399 (battery); $331 – $1,156 (alternator)15,000 – 184,000 mi

Door lock actuator failure
Door locks failing to function, requiring manual operation
Check engine light: Off
Door lock modules and lock actuators failing, requiring manual door operation. An electrical/body fault like this doesn't trigger a check-engine light.
$370 – $68367,000 – 144,000 mi
↑ Back to the problem table
AC/HVAC problems
AC not working properly, white powder from vents, blower issues
Check engine light: Off
Evaporator coil, blower motor, AC condenser, and compressor wiring issues across a very wide mileage range, including some very early-life reports. An HVAC fault doesn't trigger a check-engine light.
$600 – $1,5001,000 – 100,000+ mi
↑ Back to the problem table
Audio/amplifier issues
Audio system fails intermittently
Check engine light: Off
Amplifier and Mark Levinson premium audio component failures causing intermittent audio dropout. Not a check-engine-light fault.
$400 – $1,70084,000 – 91,360 mi
↑ Back to the problem table
Window regulator failure
Windows inoperative, making noise
Check engine light: Off
Window regulator failures causing inoperative or noisy power windows. Not a check-engine-light fault.
$150 – $45052,500 – 159,000 mi
↑ Back to the problem table
Navigation/climate control system failure
System failure, GPS signal loss
Check engine light: Off
One documented navigation/climate control system failure at $1,250, reported across a mileage range of 6,500-53,280 miles. Not a check-engine-light fault.
$1,000 – $1,3756,500 – 53,280 mi
↑ Back to the problem table
Engine wear (rough running, cold-start knock, valve cover/water pump/timing belt)
Rough running, cold-start knocking, check engine light
Check engine light: On
Rough running and cold-start knock/piston slap associated with spark plugs, ignition coils, and oxygen sensors, plus valve cover, water pump, timing belt, and VVT oil pump wear. The $200 – $7,500+ range is one of the widest — the top end likely reflects a small number of major failures (e.g. full engine/transmission replacement) rather than a typical repair. Sensor/misfire faults like these typically trigger a check-engine light.
$200 – $7,500+4,000 – 201,000 mi
Very wide range — the top end likely reflects a small number of major failures, not a typical repair cost.
↑ Back to the problem table
Suspension and steering wear
Clunking noises, whirring from steering, harsh ride, uneven tire wear
Check engine light: Off
Struts, control arms, tie rods, wheel bearings, steering racks, and CV joints wearing across a wide mileage range. A suspension fault doesn't trigger a check-engine light.
$860 – $4,4006,000 – 184,000 mi
↑ Back to the problem table
Transmission and drivetrain wear
Rough shifting, flaring, slipping, axle boot leaks
Check engine light: On
Transmission slipping/failure, axle boot leaks, and drive belt wear across a wide mileage and cost range. Transmission faults like these typically trigger a check-engine or transmission warning light.
$370 – $6,0001,000 – 178,000 mi
↑ Back to the problem table
Brakes and traction control wear
Pulsing, squeaking, worn pads/rotors, frozen calipers
Check engine light: Off
Brake pad, rotor, caliper, and traction-control actuator wear. Brake/traction faults typically don't trigger a check-engine light.
$370 – $1,39915,000 – 169,000 mi
↑ Back to the problem table
Paint, rust, leaks, rattles, and trim wear
Dashboard rattles, loose heat shields, rusted trim
Check engine light: Off
Heat shields, door handles, window regulators, and trim panel wear/rattles/rust. Cosmetic/trim faults don't trigger a check-engine light.
$150 – $2,667500 – 163,000 mi

Dashboard melting is this vehicle's standout problem. Lexus ran "Customer Support Program ZLZ" covering sticky/melting dashboards, but it expired in 2021. Since that goodwill coverage has lapsed, this is now a genuine out-of-pocket common problem for current owners.
