Service Brakes Problems of BMW 330

Federal safety defect crash report & evidence preservation notice associated recall: NHTSA recall 24v-104 (BMW integrated braking system defect) VIN: 3mw69cw02s8f20974 vehicle: 2025 BMW 330i date & time of incident: October 16, 2026, at approximately after 05:00 am incident summary & defect description: on October 16, 2026, at approximately after 5:00 a. M. , I was operating my 2025 BMW 330i (VIN: 3mw69cw02s8f20974). While executing a reverse maneuver, the vehicle experienced a sudden electronic failure of its integrated braking (ib) system. The brake pedal instantly locked up, becoming rock-hard and completely unresponsive to mechanical pedal force. Due to the complete loss of power braking assist, the vehicle could not be slowed or stopped, causing a complete loss of vehicle control. This resulted in a vehicle spin, a structural collision/impact, and full airbag deployment. The vehicle’s onboard diagnostic system caught this internal electronic component failure and transmitted an emergency brake system warning to my mobile app at 05:18 a. M. Correlation to known recall: this failure directly aligns with active NHTSA recall 24v-104 for an internal electronic short-circuit within the integrated braking system module, causing a sudden, total loss of power braking assist. Demand for evidence preservation: I demand that all electronic control units (ecus), event data recorder (edr) "black box" logs, freeze-frame failure data, and the integrated braking system module be safely preserved without modification, overwrite, or code-clearing for forensic data download and investigation.

Before the collision, my 2025 BMW 330i stalled when I tried to accelerate, so I moved into the right slow lane. The vehicle also stalled during the collision. My VIN lookup shows an unrepaired recall involving the starter-generator. I do not know whether the recall issue caused the stalling. My windshield was foggy, limiting my visibility on the left side. I could see to the right and saw another driver trying to go around me. During impact, I tried to regain control, but the steering wheel felt stuck. My vehicle rolled over. I cannot determine whether the visibility or steering conditions contributed to the crash. Dealer refused to let me inspect the vehicle, would not release the footages on BMW drive recorder. Witnesses on chp report stated the rear end collision sent my car up an embankment and flipped 2-3 times in the air before landing on its wheels.

Going into a parking spot. Applied brakes, then the car did not brake, then it accelerated hitting a Jeep and finally stopped when the driver side front hit a parking barrier and then the air bags deployed. Sudden unintended acceleration was the cause of this accident. Car was totaled.

There is a well known issue with the clip on BMW 3 series (mine is a 2017 330i) that holds the parking brake cable assembly to the body if the car above the drive shaft towards the rear of the car. The plastic clips fail frequently, causing the parking brake cable assembly to fall and the brake lines rub against the driveshaft creating a metal-to-metal noise. Over time the friction between the drive shaft and parking brake cable will eventually create failure of the cable in my opinion. I have this issue and I have seen several online videos of others who have the same issue.

While backing out of a short driveway and placed t to drive, the vehicle revved and started speeding out of control with brakes applied. The vehicle sideswiped a neighbors vehicle before crashing head on into a tree causing it to stop. I had jerked up the emergency brake and ripped the key out of the ignition. The replaced airbags did not deploy.

My BMW 330xi 2018 wagon recently passed 40000 miles. My wife heard a rubbing noise when braking a few days ago. We took car into a repair shop and they found the rear brake pads were worn down to the metal. At no time did a brake wear warning light ever alert us to this!.

On or around the first week of Dec. 2020 after filling up with gas, the car just stopped while in motion without any prior dash warning indicators. I placed the car in park and restarted the car on the first try. At that time I thought it may have been bad gas. Fast forward to Jan. 09, 2021 while pulling up to gas station car accelerates while I am applying brakes. Very scary because I could have killed someone. I put the car in park and it revved up as though my foot was on the accelerator. This has started to happen on a regular basis, although. Intermittently. Researching this issue I found this has been discussed in several BMW forums since 2002 and appears to happen in older and newer cars regardless of model types. I have maybe 165,000 miles on my car and the maintenance is very well documented and consistent.

BMW advertises as a safety feature an emergency brake assist system that "warns about the risk of collision and, where appropriate, brings the vehicle to a complete stop before it results in a crash with an obstruction, a person or another vehicle" (https://. . Read more...

Mbw 330ci 2005: on 3/22/10, @ 3pm pacific, my brake response went from "good stop" to "unsafe, bad, "cruise-to-stop". I've had my car into irvine BMW 5 times since then, and "nothing wrong" could be found. I contacted BMW n. A. About ongoing problem, when I read about the "recall" just now reported, on the 5 & 7 series cars. The "problem described" as the reason for that recall, is what I've complained to BMW since 3/30/10! my "complaint' to them, and this week, BMW na, was described to them each time I visited, and on my Bmwna call this week, as the same problem as was the cause of the recall on the 5 & 7 series, and I'd complained of this braking problem since 3/30/10, and that it occurred around 3pm on 3/22/10! two "body shops"---to which I went for a fender repair quote--were aware of my concern, and an employee at the first one checked my brake fluid. It was not low. My 2005, 330ci brakes were trustworthy, and stopped immediately. As of 3/22/10 @ 3pm, I have to depress the brake pedal down 3+ " further, to get stopped, then it's a "cruise to a stop", not a "stop". BMW cannot find anything wrong. I'm concerned about my life, and am afraid to drive on freeways here (the only way to get from a to b). I haven't had to worry about freeways, since my car stays parked, and when I drive it, it's to the dr. And back. I have 17k miles on it, no more. I would like to feel safe in my car, and the brakes work properly, but since 3/22/10, when the "lack of response" occurred, I don't feel safe. Find the problem, and help me get it fixed. Unresponsive brakes there has been no accident re the brake responsiveness on my car yet.

Car pulls severely to the left or right when brakes are applied. I have had the car serviced and asked for an alignment several times because of this issue. I was told that no alignment was needed but no explanation as to why the car pulled was given.

Re defective braking/steering in a 2005 BMW, requesting a defect investigation. The consumer stated the vehicle pulled to the left or right upon stopping. In one case, the vehicle pulled so severely that it came to a rest at an angle on the road. The wheel could not be straightened until the brake had been released.
