Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My key to my 2004 Lexus 330suv has broken 3 times. Once it broke in the ignition. I have used my key in an ordinary way. Lexus has replaced the keys but at my expense. I believe there is something faulty with the ignition and/or the key itself. Though I have not been injured, it is possible the key could break while driving and cause injury. I replaced the key in 2006, 2008 and most recently in june 2011. I have paid $220 each time in 2006 and 2008. …”

NHTSA complaint #10411605, filed 2011-07, 80,000 miles

“When I slow my Lexus ls-430 down to about 10 - 15 MPH then attempted to accelerate lightly, the car will often not respond to the throttle. I'll depress the accelerator further and eventually the car will respond by down shifting into a lower gear and accelerating very rapidly. I have contacted Lexus and they have stated that this is a result of the fly-by-wire design of the throttle and that I'll eventually learn to compensate. …”

“My electrical wiring has a huge issue. I am confident this has to be a hazard of some kind! A few years ago I started having issues locking/unlocking my car doors with the key fob. Only one or two doors would lock/unlock on command. After research I found this to be a possible actuator problem. Lexus estimated the cost to be $700/actuator (per door). Without having the actuators fixed just yet, a couple of days passed and I noticed my tail light went out. The next day a headlight went out. …”

NHTSA complaint #10627063, filed 2014-08

“The contact owns a 2004 Lexus RX330. The contact stated that while driving approximately 30-40 MPH the vehicle lunged forward violently and it also stalled when trying to accelerating from a stop sign. The vehicle was inspected by a dealer who informed the contact that she needed to reset the computer and that it would take time for the vehicle to learn her driving habits. The computer was reset; however, and the pausing and lunging forward continued to occur. The failure mileage was approximately 42,000.”
