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.

While driving normally one day, all the brake lights on the dash came on and my stopping power was diminished. I pulled the trouble codes and the only code was C1391 which indicates an "Abnormal Leakage in the Accumulator". This is a major safety concern and a costly repair if left to the customer.

For several years now, I have been experiencing incidents where someone and/or a group is hacking into my radio and/or satellite radio systems and trying to lure me into conversation, make comments, or actually sing to whatever it is I'm listening to. Most incidents have been reported to the NHTSA, which they have been filing. Please know that sometimes the "noise is constant", as well as it appears that someone is actually connecting to my vehicle because I can feel it (also reported). I also hear people speaking from the outside of my vehicle (usually the front end on both sides). It has become a distraction at times, which poses risk to not only myself but other drivers as you can imagine. What can be done to mitigate someone attaching to my vehicle? I am also under the impression that they are recording me or using me as podcast material, which is against the law in various states to varying degrees and without my authority. Please advise, as it has been ongoing for years. Thank you for your assistance. DATES OF INCIDENTS: Ongoing since late 2018, if not earlier.

Please add to previous filings / communications - thank you. PROBLEM PARTS: Satellite Radio and/or AM-FM Radio; Bluetooth; Speaker System; Unknown Device The parts have not malfunctioned however, there appears to be a person and/or group attaching to my vehicle via several conduits related to any radio input and/or speakers. This has been ongoing for years where I have submitted previous reporting based on hearing voices not directly affiliated with the broadcaster(s); being the victim of Havana Syndrome; Radio-Frequency Assaault; Satellite Terrorism, and other unwanted Amateur Radio broadcasters that may or may not be acting with malintent. I am still hearing information in and outside of my vehicle - some of which are directed against my person. Furthermore, someone is now "connecting to my vehicle" (I can feel hits to both the front and back of my vehicle) while I am sitting in parking lots, rest stops, gas stations, etc. This "connecting to my vehicle" via hard hits became obvious since last week ([XXX]) in Warrendale, PA while I was reviewing my travel plans. After the "hits" I began hearing voices in my car, as well as from externally. The voices and/or broadcasts I am hearing are mainly derogatory, pornographic, and/or threatening in nature and, at times, have caused me to get confused that may or may not become problematical when driving. There are also broadcasts that sound as if they are trying to recruit or lure me into sex trafficking, as they state that I have no money, etc. Lastly, I am being told that I am unloved, have no family, and that my family is somewhere else - that I can have a baby, etc., - that "You are one of us." [sic] Since leaving my father's home ([XXX]), there have also been several incidents of Satellite Terrorism and Havana Syndrome associated with various locations: Erie, PA to Texas to North Carolina, etc. - at every hotel, rest stop, while sitting in my car, etc. I believe someone is trying to abduct me.

received CUSTOMER SUPPORT PROGRAM 24LE01 NOTIFICATION for issues related to Brake Booster and Brake Booster Pump Assemblies. Indicator lights, such as Master Warning Light (Yellow) and SLOP Indicator (Yellow) have appeared while reversing out of a parking spot when no water puddles are present and moving foward (clear day/road) where the vehicle doesn't catch the gear to move initially. Once braking, the system seems to reset itself and allows for a "normal drive". The experience is intermittent, and not often- the dashboard warning lights come on infrequently and is not consistent. Lexus Dealer/Service Shop advised a charge of $145 to look for diagnostic codes C1391, C1252, C1256, C1253. If they find these codes, then they will check the extended warranty to determine if they will charge you or not under their customer support program which really doesn't tell the car owner one way or another. The service adviser said only a Lexus authorized dealer can check for the diagnostic codes and can't be obtained from a traditional code reader at retail outlets such as Autozone, or OReilly, etc. The issues with the Brake Booster and Brake Booster Pump Assemblies sounds like a critical issue with deadly affects if not looked into. The method of the dealer seems shady to get this looked at and for a price to be passed on to the car owner.

I noticed that the brakes felt a bit weird when engaged. I felt a touch on the brakes and heard as if the abs pump was pumping. Thinking it was something of a fluke, I didnt pay any further attention to it. After not driving the car for couple of days, when I turned on the car a day ago the warning (!, brake, ABS, and traction control lights) are all lit up on my 2015 Lexus CT200h. After doing some research, I have found an old recall for Lexus CT200 H for (2011-2014) see (L-SB-0009-210) from May 11,2021 letter online. A code scan revealed a C1391 error, indicating an abnormal leak in the accumulator. This ABS module is the same as the recalled Toyota ABS module. Please this could be dangerous to me and my family.

Urgent Safety Complaint Regarding Brake System Failure and Manufacturer's Extended Warranty Acknowledgment To Whom It May Concern, I am writing to formally file a complaint concerning a critical safety issue with my vehicle, which has significantly impacted its braking system. This issue not only presents a severe risk to my safety and that of other road users but has also been acknowledged by the manufacturer through the issuance of an extended warranty for this specific malfunction. Approximately one month prior to the complete failure, my vehicle began emitting an unusual hissing noise from the brake pedal area, leading to a near-total loss of braking functionality. The incident was characterized by the activation of the Anti-lock Braking System (ABS), traction control, and brake warning lights, accompanied by a repetitive buzzing noise every 5-10 seconds related to the brake system's charging mechanism. The brake pedal became exceedingly soft, rendering the vehicle's brakes nearly non-existent. Despite the vehicle being only a year and a half old and previously showing no major issues, this braking system failure occurred suddenly and without warning. However, in light of the manufacturer's recent communication regarding the extended warranty for this specific problem, it is clear that this is a known issue that poses a significant safety risk. Given the manufacturer's acknowledgment of the defect through the extended warranty, I urge the National Highway Traffic Safety Administration to investigate this matter with heightened urgency. The potential for harm not only to myself but to other individuals on the road necessitates prompt and decisive action to ensure the safety and reliability of affected vehicles. I am prepared to provide further information and cooperate fully with any investigations into this critical safety issue. Thank you for your immediate attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. While Lexus paint quality, durability, and resistance to environmental factors is continuously being improved, it remains the responsibility of the dealer to protect and maintain the vehicle’s paint finish from the time of arrival at the dealership until retail delivery to the customer. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
