2024 Lexus RX: problems, recalls and reliability

“When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This happened to me once, and I noticed it trying several other times.”Owner report · Lane Departure · Apr 2026

“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.”Owner report · Service Brakes · Mar 2026

“A 2024 Lexus RX 350 H 12 volt battery is discharging leaving owners stranded. AAA must be called to jump the battery. This has happened four times, each when opening car doors to clean the vehicle. From my understanding the battery discharges within 5 minutes leaving the auxiliary system without power and the inability to start the car. Not exactly sure what is causing the battery drain but vehicle becomes unable to move, open doors or move since drive train will not allow any movement. Owners have been stranded four times waiting on help. Dealer unsure of problem but exploring electrical issues, battery issues, software issues or unknown issues.”Owner report · Electrical System · Feb 2026

“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.”Owner report · Service Brakes · Feb 2026

“My 2024 Lexus RX 350h experienced a catastrophic 12V battery collapse (2.00V), disabling the electronic 'e-Latch' door system and rendering interior handles non-functional for standard use. While a manual override exists, it is not intuitive for emergency egress. Additionally, the electronic parking brake and shift-by-wire systems remained physically locked, preventing the vehicle from being moved to a safe location during the power failure. I am reporting this as a failure of primary safety and fail-safe protocols. Dealer did not consider this a a problem because he said I "needed to read the manual before I ever drove the car"”Owner report · Unknown Or Other · Jan 2026

“When coming from a stop, the car will not respond to the gas pedal being engaged OR it will begin to engage and then no response leaving the car rolling for a few seconds until a response is recieved and the car engages again. This has caused us to be put in harms way MANY times with oncoming traffic when making turns or in front of oncoming traffic in intersections. The dealer states this is not a known issue however it is all over the internet that hundreds of reports of this issue have been made. The dealer states no fix since they don't "have a problem". MAJOR safety issue. We have reported this many times to Lexus now with no resolve or help from them.”Owner report · Engine · Jan 2026

“When accelerating at slow speed, the engine or turbo turns off which causes the nose of the car to take a hard nose dive and then turns back on within 1 second but results in a big loud sound coming from engine/transmission. This issue almost caused on accident because it does a hard engine break where I was almost rear ended but from other drivers perspective, it might seem that I'm break checking them. Showed car to Lexus but they said it is normal but it not normal and should be investigated as it can cause harm to everyone involved if accident were to occur. Situation occurred 3 times this week and it is entirely random and can't replicate at will.”Owner report · Engine · Jan 2026
