2021 Lexus Ux Hybrid

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

The contact owned a 2021 Lexus UX 250 Hybrid. The contact stated that while their father was driving approximately at 65 mph when the warning for tire low pressure had illuminated. The driver pulled over to check the tires to the side of the road. After pulling over the driver noticed smoke coming from underneath the hood between the tire on the driver's side. Both parties exited the vehicle when suddenly the vehicle burst in flames. The fire department extinguished the fire and a report was filed. The vehicle was towed and totaled. The dealer was informed about the incident. After investigating they were unable to determine the cause due to the state of the vehicle from the fire. The contact stated that they were no injuries or medical attention needed. The manufacturer was made aware of the issue and opened a case regarding the matter. The approximate failure mileage was 250.

I'VE OWNED SEVERAL LEXUS HYBRID VEHICLES. I HAVE LOVED THEM ALL EXCEPT THE LAST, A 2021 LEXUS UX WHICH, I LATER FOUND, CAME WRAPPED WITH AN UNWELCOME SURPRISE. WITHOUT HAVING TO POUR THROUGH 107 PAGES OF THE FEDERAL REGISTER, I'D LIKE TO KNOW IF ANY OF THE CREATORS OF THE FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 141 HAD ANY IDEA OF THE UNINTENDED CONSEQUENCES THIS RULE WOULD SURELY PRESENT. ITS PURPOSE IS OBVIOUS. BUT THE HEAVY-HANDED WAY IT HAS BEEN THRUST UPON THE CONSUMING PUBLIC IS NOT. I'VE ASKED MY DEALERSHIP IF THEY CAN TONE DOWN THIS, FRANKLY, OBNOXIOUS SOUND THAT'S TRIGGERED. OF COURSE, THE ANSWER WAS NO! BY THE WAY, THIS IS THE SAME DEALERSHIP, ONE WITH WHICH I'VE DEALT FOR YEARS, THAT FAILED TO DISCLOSE THE FACT THAT MY NEWEST VEHICLE, LIKE IT OR NOT, HAD AN ADDED FEATURE. WHILE THE MANDATE WAS NOT CREATED BY THEM, THEY'VE CHOSEN TO HIDE BEHIND IT. AND, AS A RESULT, HAVE LEFT THE CONSUMER TO DEAL WITH THE CONSEQUENCES. THIS ODD TURN OF EVENTS REMINDS ME OF ANOTHER INDUSTRY, ONE THAT IS THE SUBJECT OF CRITIQUE IN A BOOK TO BE RELEASED SOON. SADLY, PUBLIC SAFETY NOTWITHSTANDING, OUR OTHERWISE PERFECT BUT HIGH-DECIBEL-EMITTING UX250H WILL BE A DAILY REMINDER OF IT. THUS, I FEEL PERFECTLY ENTITLED TO MOUNT A SIGN ON THE CAR WARNING OTHERS THAT SAYS, 'THE SOUNDS YOU HEAR FROM THIS CAR WHEN BACKING OR DRIVING AT SLOW SPEEDS ARE COURTESY OF (NAME OF DEALERSHIP) - WHO INSISTED ON IT. HOPE YOU ENJOY!'
