What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Lexus IS 350, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
TL* THE CONTACT OWNS A 2007 LEXUS IS 350. WHILE DRIVING 35 MPH, THE AIR BAG INDICATOR ILLUMINATED WITHOUT WARNING. SEWELL LEXUS IN FORT WORTH, TEXAS REQUESTED THAT THE VEHICLE BE BROUGHT IN FOR DIAGNOSTIC TESTING. THE VEHICLE WAS DIAGNOSED BY AN INDEPENDENT MECHANIC AS HAVING SQUIB CIRCUIT FAILURE INSIDE OF THE AIR BAG, WHICH CAUSED THE SRS INDICATOR TO ILLUMINATE UNDER CODE: B1861. THE INDEPENDENT MECHANIC STATED THAT IN THE EVENT OF A CRASH, THE SQUIB CIRCUIT FAILURE COULD POTENTIALLY DISABLE THE AIR BAGS. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS 141,896.
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
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
MELTING DASH AND DOOR PANELS. *TR
THIS IS THE FIRST BRAND NEW CAR I'VE EVER PURCHASED AND KEEP IT IN A GARAGE DURING THE DAY SINCE I HAVE TO DRIVE A WORK VEHICLE BETWEEN DAYTIME HOURS. THE GARAGE IS NOT AIR CONDITION BUT DOES NOT GET EXTREMELY HOT. THE SOFT RUBBER INTERIOR HAS DETERIORATED AND GOTTEN VERY STICKY AND BRITTLE. IT CAN BE RUBBED AWAY WITH A QUICK SWIPE OF YOUR FINGER. ITS AFFECTING MY DRIVER SIDE INTERIOR DOOR TRIM PANEL AT THE GRAB HANDLE. ITS CONSTANTLY FALLING APART AND GETTING GUMMY RESIDUE ON MY HANDS. THIS IS THE ONLY ISSUE WITH THIS CAR AND ITS NOT FAIR TO US CUSTOMERS BECAUSE THIS IS A VERY EVIDENT MANUFACTURER DEFECT. I NEVER RECEIVED A NOTICE OR WAS INFORMED OF ANY ACTION THEY WOULD PROVIDE FOR THIS FLAW. *TR
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
VSC LIGHT COMES ON RANDOMLY AND SOMETIMES STAYS ON FOR DAYS. ABS LIGHT COMES ON WITH IT AND CHECK ENGINE LIGHT. VERY UNSAFE WHEN IT HAPPENS I HAVE BEEN TURNING AND THE TRACTION WILL CUT OUT. BECAUSE OF THIS ISSUE WE DO NOT DRIVE THE CAR IN THE RAIN. *TR

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.

THE SPEEDOMETER NEEDLE AND TACHOMETER NEEDLES ARE LED LIGHTS THAT ARE SUPPOSED TO BE ILLUMINATED. IN WARMER CLIMATES THERE IS A VERY HIGH RATE OF FAILURE WELL INSIDE OF THE 100,000 MARK. THE LED LIGHTED NEEDLE FAIL, HENCE YOU CAN NO LONGER NOTE YOUR SPEED. THERE ARE NUMEROUS COMPLAINTS ON LINE AND 3 OR 4 VENDORS THAT SPECIALIZE IN THE REPAIR BECAUSE IT IS SO PREVALENT. NOT BEING ABLE TO SEE YOUR VEHICLE SPEED AT NIGHT IS CERTAINLY A SAFETY ISSUE.
LOW BEAM HEADLIGHTS KEEP GOING OUT. I HAVE DIRECTIONAL HEADLIGHTS THAT WHEN I TURN MY VEHICLE ON, MY LIGHTS WILL TURN ON (IF DARK ENOUGH OUT) AND THEY MOVE POINTING DOWN AND THEN UP. WHILE DRIVING THEY ALSO DO THIS AND GO LEFT TO RIGHT. WELL WHEN I FIRST START MY CAR THEY BOTH WORK. AS SOON AS LOWBEAMS MOVE STRAIGHT TO DOWN AND THEN TO UP, ON UP MOVEMENT MY DRIVER SIDE CUTS OUT. DOES NOT TURN BACK ON. *TR

THE FOOT REST NEXT TO THE BRAKE AND ACCELERATION BROKE-OFF (ITS PLASTIC) AND LODGED BETWEEN THE BRAKE PEDAL AND FLOOR BOARD. LUCKILY I WAS NOT MOVING AT A HIGH SPEED AND WAS ABLE TO COAST TO A STOP.

Transmission
Reports naming the automatic or manual transmission, including shifting behaviour, shudder, slipping and transmission control modules.
From owner reports, verbatim
THE COLD IDLE SPEED ON MY CAR IS BETWEEN 1000 AND 1500 RPMS. AT CERTAIN SPEEDS, THIS CAUSES THE CAR TO SLOWLY ACCELERATE WITH THE FOOT OFF THE ACCELERATOR. EVERY OTHER CAR I'VE DRIVEN WILL DECELERATE WITH THE FOOT OFF THE ACCELERATOR. THIS CAUSES ME TO RIDE THE BRAKE AT CITY SPEEDS TO MAINTAIN A SAFE SPEED, WITH THE BRAKE SIGNALS POTENTIALLY CONFUSING TO OTHER MOTORISTS. ADDITIONALLY, WHEN NAVIGATING SNOWY OR ICY PARKING LOTS & STREETS, HITTING A SLIPPERY PATCH UNDER THE HIGH COLD RPMS WILL CAUSE THE CAR TO TEMPORARILY BREAK FREE OF THE BREAKS, SPIN THE WHEELS, AND LURCH FORWARD. THE CAR IS EQUIPPED WITH WINTER TIRES. THIS IS NOT A SINGLE OCCURRENCE, BUT HAPPENS WHENEVER THE CAR IS DRIVEN WHILE COLD. *TR
