Example complaints

“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. …”
NHTSA complaint #11715077, filed 2026-02“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.”
NHTSA complaint #11639180, filed 2025-01“Brand new vehicle- 12volt battery failed after 5 weeks. Lexus initially stated battery fine. Then battery failed while in their possession- Lexus replaced battery. Few weeks later battery failed again. Lexus tested & replaced battery for second time - but battery kept draining & they were unable to repair after having vehicle at dealership for 3.5 months”
NHTSA complaint #11671336, filed 2025-07“The contact owns a 2024 Lexus RX 350. The contact stated that while driving in a School Zone, a message warning the contact about entering a school zone would be displayed. The contact stated that this was a distraction while driving instead of a safety feature. The vehicle was not diagnosed or repaired. The manufacturer was notified of the issue but offered no assistance. The failure mileage was approximately 3,000.”
NHTSA complaint #11663115, filed 2025-05, 3,000 miles“The car started showing multiple error messages on the dash and then shut off while in operation, it would not restart without a service call and battery boost. This has happened multiple times. Online research shows this is a common issue with the hybrid models - the 12v battery doesn't get adequately charged, voltage drops and car ceases to work - even while mid drive on the road, this is extremely scary and dangerous.”
