Owner report 11578930 · 2024-03-22 (March 22, 2024)
I started to notice that when in reverse or coming to a brake at low speeds, the brake pedal and car starts to vibrate/stutter. I have driven hybrids for the last 5 years and never had this issue before. It is very strange that the car vibrates when coming to a stop and it is on going. It happens and then it stops, but always starts up again.

Owner report 11629328 · 2024-12-06 (December 6, 2024)
While driving on a local highway recently, my forearm brushed the automatic shift knob while reaching to place my phone on the wireless charging pad. The transmission shifted into neutral, resulting in an unexpected loss of speed. It took me a few seconds to realize what had happened - I shifted back into Drive, and resumed my trip. No accident resulted from this, but it has happened twice in the month that I have owned the car. I reported the issue to the dealership thinking my car had a problem - they said that this is the way the car is de…

Owner report 11636883 · 2025-01-19 (January 19, 2025)
Below is the email that I sent to both the manufacturer and the dealership: I hope your Christmas Eve was better than mine. My son and I were driving up to the Poconos [XXX] to go skiing and I noticed the sonar detection light come on. When we were driving back from the Poconos, the transmission would not catch around the second or third gear. The RPMs would shoot up. The dash / warning lights lit up. I pulled over to the side of the road and I called Lexus dealership, service center, and road side assistance. However, due to the fact that it w…

Owner report 11673022 · 2025-07-12 (July 12, 2025)
I experienced a sudden release of toxic fumes from the vehicle between the steering column and instrument panel area on June 29, 2025, while driving. The fumes struck my face, caused immediate bitter chemical-like taste and made me feel physically ill and extremely concerned for my safety. The fumes were strong enough to leave a lingering taste described as “bitter and green” with initial symptoms of headache, lightheadedness, nausea, vomiting green substances, eye irritations, nose and throat irritations. The local auto dealership inspected th…

Heard clicking noise coming from steering wheel. Car shimmied when breaking off of freeway. Newish car, only 20,611 miles. Took into dealership before anything went awry. Dealership said never heard of the steering problem before. Turned out it was a tie rod going bad and repair was covered by warranty. Break issue was also covered by warranty.
