| Service Brakes problems |
I was stopped at a red light with brake on, my vehicle leaped forward on its own three times, with the brake on, the force was so strong I thought someone rear-ended me. No warning lights, the acceleration was load.
On Feb. 10th 2026 I was driving north i405 (los angeles). The car suddenly applied emergency breaks in the middle of the freeway, while there was no car in front of me, at least for 100m. I was lucky that the car behind me didn't hit me. It could be a serious multi-car collision.
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.
When I start to coast to come to a stop the engine will rev, even though the energy flow screen shows the gas engine is disengaged and running only on ev. The engine will rev, even with me using the brake. But the ev light is off and the rpms are rising. Eventually the ev light will come on and the gas engine will cut off and the vehicle will switch to ev mode. My mpg has dropped to 36. 2, so something is not right. When I was at the dealer for my 10k service, they told me this was the car "shedding" the extra energy, but the battery was not fully charged, so I'm perplexed and frustrated.
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 christmas eve 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 was christmas eve, the offices were closed. I managed to make it to my parent’s home, but it was a very dangerous ride on rt. 80. The odometer stated that we were going 50 mph, but we were crawling and the rpms were 4000. The rpms at rest were always over 1000. Additionally at times, the gear would not shift into second or third and/or bottom out. Obviously the transmission is beyond malfunctioning. Below are pictures including: 1. ) check your engine: a malfunction in the electric control of the engine, throttle or automatic transmission has been detected. . . 2. ) a malfunction in the intelligent clearance, sonar system has been detected 3. ) traction control turned off 4. ) secondary collision break system malfunction, 5. ) system malfunction 6. ) drive-start control malfunction. The vehicle has just over 3000 miles. I am beyond distraught. My phone number is (908) 625-9277. However, I think it's best if we communicate through email at this point. I planned a family ski trip to killington, vt for the new year. I would like to request a loaner vehicle so I can salvage this holiday. I look forward to hearing from you and your service department.
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.
