The contact owns a 2015 Lexus Ls460. The contact stated that while turning left the vehicle's accelerator pedal provided no acceleration. The contact had to pump the accelerator pedal several times before the vehicle would speed up. The contact spoke to the dealer Lexus of lexington (1264 e new circle rd, lexington ky 859-600-0293). The contact was informed that the failure was a problem across the board with a lot of Lexus with the transmission hesitating. The transmission provided several modes of the transmission with a knob on the console that allows the driver more options. The dealer suggested to keep it out of the eco mode which caused a lot of hesitation. The vehicle was not repaired. The manufacturer had not been contacted yet. The failure mileage was 26,000.

Purchased a 2007 Lexus Ls460 on March 5th, got a prepurchase inspection and there are multiple things that have gone wrong. The latest repair needed is the fuel pressure sensor, costs approx $1525 at the dealer. I contacted Lexus to see if this would be part of the recall and case manager amanda deantonio stated that based on the miles, age and my service history, loyalty to Lexus, they can not assist me with getting this repair done. I am awaiting a supervisor to call me back regarding the repair that I believe should be covered under the "fuel pressure sensor" leak, elf campaign. On may 15, 2015, the gasket was replaced and the fuel pressure sensor sealing surface was repaired. I am now looking at a safety issue with this vehicle I purchased due the fuel pressure sensor shorting out my ecm, which has caused my car not to start. I am asking Lexus to replace this part at no charge due to the faulty part. Consequently, the fuel pressure sensor is installed where the plating material on the gasket seating surface is.

While coming to stop, car suddenly and violently accelerated. Hard braking held the car and only placing car in park stopped the acceleration,.

This has happened over 5 times since owning the vehicle. After oil changes and off/on throughout owning the car it will have a hesitation on the acceleration. It will have high rpm's, but it is not going anywhere (loud engine noise). This is very dangerous if it decides to do this when passing someone on the highway and this morning it did it while pulling out into traffic and almost got hit as the vehicle did not move.

Took my vehicle in for a routine 60k service. The only service provided was an oil and filter change, tire rotation and maintenance reminder reset. The issue that has occurred since has been hesitation or poor acceleration from a stop and low speeds.

After an oil change at the dealer, the car is unable to accelerate, sluggish, and the powertrain acts lethargic, particularly when trying to enter the freeway or merge into traffic. The dealer has performed a software update, however the problem still persists. This only happened after and oil change. Several other Ls460 owners I know complain about the same phenomenon. Lexus has no answer.

Noise in front end of new 2010 Lexus 460 awd with 250 miles (approx) on clock. Thought initially to be a tire problem. Returned to dealer at 850 miles did another tire check and finally replaced faulty bearings in both front wheel assemblies.

This model hesitates in changing (hunting) gears on hard accelerations. Three times I have been in near accidents on merging into freeways, changing lanes from a straight path or from corner turns. The car responds very slow on hard acceleration. The web is full of similar incidents with this model car. I suspect it has something to do with Lexus' eight speed transmission and how their software is integrated with the powertrain. Lexus had a "fix" for this problem but did not quite fix it completely and they insist the car is working as designed. . Read more...
