Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

BMW jointly owned vehicle, was not returned to customers on demand, nor swapped as is customary business practice (I.e. BMW repair/recalled for BMW loaner car), and held for unreasonable amount of time. BMW recalled the vehicle, in part, defective airbags, and was to send a consent form to the customers prior to ordering parts/repairs. The customers never received the consent form as assured and expressed concerns about the BMW who damaged the vehicle in their possession or disabled state. July 15, 2016 BMW flatbed delivered with unidentified chemicals/toxins that resulted in front end physical damages and/or toxins in BMW that resulted in "poison exposure", toxology tests pending. The toxins maybe airbag chemicals, sodium azide, hydrazoic acid, or others, and need BMW tested. Please inform on who specifically performs these tests or Agency that does quickly due to the toxic nature. BMW had a duty to disclose these facts to customers, insurance, government, and others. 49 usc Safety Act 30101. Dot states ¿loaner vehicle¿ is customary practice in airbag recall, an obligation oem dealership, thus request the process in securing the loaner vehicle or reinstatement. BMW by affiliates, unilaterally took BMW loaner without providing a repaired BMW, unfair exchange, and was returned in a disabled status. ¿but for¿ wrecked/recalled defective BMW, a loaner would not have been required, Safety Act, 49 usc 30101. Please respond in writing, the process to (1) secure chemical tests; (2) vehicle safety review or decontamination, and (3) loaner car approval process for insurance. NHTSA Safety Act, 49 usc §30101 delegated by secretary of transportation, 49 cfr §1.95, inspect/investigate §30166(B)(1); civil penalties §30165(B); ensure recalled §30118-119; adequacy of recalls 49 usc §30120(C)(1), accelerate remedy programs 30120(C)(3); and other 49 usc §30166(G): BMW loaner

The vehicle (1.6 turbo) has a hesitancy to engage in acceleration relative to pressing the accelerator pedal. Once engaged, it immediately jumps out to a quick, jolting and what feels like an uncontrollable start. This typically happens at stop/start intersections where the car comes to a full and complete stop. Yesterday, (07.20.16) the vehicle choked and sputtered and almost stalled on a small rise when traffic started moving through a just-turned green light at a very busy intersection during rush hour. The tachometer winds out in a manner disproportionate to the speedometer reading. This does not mimic the effects of a turbo lag. Rather, it feels like the vehicle isn't getting a timely delivery of gas to the engine firing mechanisms (we would liken it to a dirty fuel line or a clogged carburetor on older cars), or the dual clutch system is debating whether or not to get in gear when demanded, or whatever device that interprets driver commands (pedal pushing) to engine performance isn't responding efficiently. The car has had one shop visit for this issue and the dealer (werner Hyundai, tallahassee) stated they 'reset the software." I will be taking the car back to the dealer the week of July 25, 2016. Unfortunately, I anticipate this issue will lead to a wreck, most likely from 1) being hit from behind as the car tries to figure out whether or not to accelerate, or 2) being T-boned at an intersection because the car won't accelerate through a rush-hour yellow light, or 3) being T-boned because my car launched (literally) out into oncoming traffic (that initially was at a safe distance away) once it got past the choke/sputter/stall point....updated 08/01/16

Vehicle defects reported or recalled, BMW, oem, or other, yet with known defects was requested to drive an unsafe vehicle that is 'imminent danger' that can cause serious injury or death: Airbags. BMW replaced driver side airbag in 9/ 2014 then passenger side. Yet in 2015 accident, the airbags failed to detonate, and injury to persons/property occurred. BMW recalled driver's side airbag (2nd repair/3rd airbag) in 2015 and parts are on back order. BMW has the 'defective vehicle' (I.e. other issues engine, seat belts, etc. Remain) and provided a BMW loaner car through their affiliated partner (Toyota's jv alliance) enterprise in good faith pending repair. In June 2016, a 'cease & desist' was placed on the BMW, in part, due to a federal investigation or injury (I.e. defective airbag- explosive device~shooting shrapnel) that leaves 'driver in harm's way'. one could infer 'attempted murder' if the driver is placed behind the wheel of a defective vehicle or airbag: Millions of recalls. I am a material witness and am reporting intimidation, threats, hostility, and bullying over the BMW or defective airbags. This has resulted in professional defamation, personal injury, financial distress, and sabotage in various instances (to be reported in separate package to be sent to investigator due to confidentiality). The most recent occurred around June 23, 2016 when BMW/enterprise rental car stating "grand theft" of the vehicle in their possession or awaiting a swap? simple fact that BMW stated that an 'interim fix' was approved by dots but needed signed consent forms-- was sending them to me. BMW did not follow procedures, 'unauthorized entry, removal, destruction' of airbag with a 'cease & desist¿. on 6/24/16 going to enterprise/alamo-orlando was no issue/no unpaid bill. This did not stop continuation of harassment or retaliation (e.g. asef) unconstitutional or uncivil conduct.

Vehicle leaks large amounts oil from valve gasket cover and oil filter housing compartment. I believe the engine block must have loose bolts which is causing the oil to leak and further cause a hazard in a possible engine fire due to this assembly of the engine. I am assuming BMW is well aware of this issue and believe a recall should be available.

While driving in normal rush hour traffic my wife heard a loud pop from the engine compartment. The car lost power, brakes. She started to coast to the side of the road when other commuters started to yell at here to get out of the vehicle, at that time the cabin started to fill up with smoke. She tried to lower the window but that had lost power also. She was able to drive the car into the snow at the side of the road to stop it and then exited the vehicle. The 325xi started to burn and shortly was a total loss. Thank god she got out ok but was traumatized by the incident. Since this happened we have found many similar fires documented on the web.
