2007 Lexus RX400H - Ratings, Complaints and Recalls

"toyota and lexus are aware of the fact that what is called break actuator assembly, part number 44050-48191 (for toyota highlander hybrid 2006-2007, and new part number for lexus rx400h 2006-2007) and 44510-48060 (old/original part number for rx400h 2006-2007) are faulty resulting in the break system failing creating an extremely dangerous situation. toyota extended the warranty for the part, but this extended warranty does not cover all vehicles, as it is not a recall. (the extended warranty has a maximum 150k miles or 10years clause but this is beyond the point regardless.) the part and repair costs more then $3000 at a toyota/lexus dealer. toyota/lexus is not offering a recall to avoid paying for the large number of cars out there with this well known issue which essentially renders the cars not drivable, unless the owner pays out of pocket what is close to half the current value of the car, for a defective item that is failing consistently in all these cars. toyota/lexus should recall the part, rather than just offering an extended warranty. this is a very well known problem, for which people have complained (including in nhtsa) for years, which forced toyota/lexus extend the warranty, but this is not enough as it does not cover all vehicles that it should cover."

"brake actuator failure reported by dealer because booster pump is running frequently. no info from toyota and toyota declined repair . dealer indicates my vehicle is not under extended warranty. 117000 miles on my car."

"brake actuator failed at 117000 miles. verified by dealer and suggest replace brake actuator and pump assembly. no notification ever"

"car has been making a clicking noise during stops for a year. i chalked it up to something unimportant. on 2/20/21, the 'check avs,' 'check abs,' and 'check brake system' lights all came on, and car lurched while backing out of my driveway. i was driving my wife and daughter at the time. brought lexus to my local mechanic on 2/22/21. after several days, mechanic returned the car to me, saying he could hear the clicking and, according to his research, it could be the brake actuator given lexus had done a warranty extension on this part in 2016. he told me this repair would cost in the thousands of dollars, and advised me to contact lexus. spoke with lexus brand manager on 2/25 who told me about warranty extension zlg for actuators in 2016, and told me that in order for lexus to ascertain whether or not the car was experiencing an actuator failure, it must be inspected by a lexus service center. because i was told about the specific extension and asked to take it to lexus to diagnose the issue, i assumed lexus would cover the repair cost. i took the car to lexus santa monica on 3/2/21 and was notified that the problem was related to the brake actuator, and that the cost to repair would be $3000 plus tax. i relayed to lexus sm what i was told by lexus corporate, and lexus sm told me they would call lexus corporate and see what they had to say about warranty extension 'zlg.' ultimately, lexus would not cover cost because the part was outside the extended warranty. i spoke with another lexus case manager about why a warranty extension was offered as opposed to a recall, and he said i should lodge a complaint with nhtsa. i also spoke with his supervisor, who said lexus would never pay for a part outside a warranty, even a faulty part given an extended warranty. nobody in the lexus chain of command can tell me if the car is safe to drive. i will support class action suit."

"brake actuator failure has been added to a bulletin for extended warranty and not a recall. this is a costly malfunction that toyota is aware of and they should take care of all vehicles as not to compromise braking and accident avoidance."

"tl* the contact owns a 2007 lexus rx400h. the contact stated that while operating the vehicle, the abs sensor light illuminated and the stopping distance was extended while depressing the brake pedal. additionally, the traction control light was also illuminated and the speed was reduced. the vehicle was taken to the local dealer south bay lexus located at 24777 crenshaw blvd, torrance, ca 90505, who diagnosed that the abs actuator was defective and needed to be replaced. the vehicle was not yet repaired. the manufacturer was notified of the failure but no assistance was offered. the failure mileage was 150,000."

"the lights all came on abs system came on stabilizer air bag took to lexus they diagnosed the problem as the brake actuator i research and found that on lexus club this is a big problem with my year and other years they acknowledge this by giving an extended warranty. but fall short to assist with after. there is many complaints i researched there is also a noise that is related to this problem the noise comes from the actuator, but being unfamiliar with the car normal features i failed to identify the problem i have heard this noise for a very long time i have always felt this pulse but thought it was normal i owned this vehicle now for 5 years. i thought the noise was the hydraulic system lowing the vehicle air down like my navigator did but that was the noise of the actuator going out. the brakes always felt like they had a delay or hit hard like a jerk just thought this was caused by sensitivity. it upsets me that lexus is and has been aware of this problem and never informed me and the problem just got worse the brake system is so vital why would they not after they realized this is a problem i had the warranty provider whom extended this warranty on this part but neither informed me even though both had my current information. its a problem that lexus and its mother toyota know of and failed to make the problem right. if there is a problem and they recognize it why not make it right! is my safety not important to lexus and toyota? #toyota # lexus #actulator #safety"
