I pulled out onto Southside Blvd. My brakes failed, my driver’s front of the car hit a Waste Management garbage truck right back tire and cut the sidewall of the tire. The engine was racing, the truck pulled off the road, and I had sudden unintended acceleration. I immediately turned into a strip center and my car was racing through the strip center, the brakes were not working, the car controls were not working, and I turned the ignition switch off and the car stopped. The car had to be towed. Presently my insurance company has issued an estimate to repair the cosmetic issues, but not the mechanical issues.

In Oct 2022, I was driving normally and suddenly got a message on the dash saying something like "Coolant low, please top up when you have a chance". A minute or so later, I got the red warning "Engine Overheated, turn off engine when safe" and it went into limp mode, and I pulled over immediately and had to flatbed my car to a dealer. Then told me there was a coolant leak (which I was not aware and there was no error message regarding coolant prior to the incident.) And they told me there was a recall on my vehicle coolant vent line. Although I had check NHTSA website frequently and did not see anything being recalled. They replaced the coolant vent line for free. Fast forward 21 months and less than 5000 miles later, I brought the car in for oil change. Upon inspection of my vehicle, the technician noticed some fluid seeping through the turbo coolant feed line and there were buildups. Please see video here. [XXX] . They suggested replacing the turbo coolant feed line and turbo return light for $2,500! I mentioned the incident two years ago due to a coolant leak that was being recalled, if this is related. They told me the recall was only the coolant vent line. The issue now is the turbo coolant feed line and return light. And over time, the coolant just "starts to leak on those lines due to its material". This is a 6 year old mildly driven vehicle with 35K miles. How can the coolant line material so bad that it would start to leak after 5+ years? Found some threads online and there were other people having the same issue. The manufacture should have put in some quality coolant lines. There were other recall in other models (18V755) for regarding a coolant leak that may result in an engine fire, which increases the risk of a crash and injury. If the line material of my coolant feed and return line by nature will start to leak after five years, wouldn't it be the manufacture's responsibility to remedy it before it cause safety issue?

Electrical SystemDec 2023 · ODI 11557903Details +

- My car started having intermittent electrical issues. The first warning something was wrong was always the cars instrument cluster would start flashing, and the audio system would also drop in and out. Then later other malfunctions would start to show up on the center Nav Screen, some of the warnings are listed here : ○ Audio/speakers would cut out randomly while listening to music ○ Air Conditioning instrument cluster display lights would flash going in and out ○ “Parking assistance malfunction” warnings ○ "Increased Steering effort required" warnings (one time the steering locked while driving ~30mph for half a second) ○ Transmission malfunction warning (I have the transmission ‘jerk’ suddenly 1 time when I was slowly backing up in a 3 point turn), ○ Drivetrain malfunction warning. - My safety was put at risk because the power steering locked once, sometimes the steering would become difficult, and the engine jerked while driving - I brought it into a mechanic: they originally thought it was something wrong with my alternator (Invoice 1), but they couldn't really figure out the problem since it was intermittent. The alternator ended up not fixing the problem. I brought it back to them after the alternator was replaced and the same issues were present. They ended up checking the battery and saw that the positive battery cable had come loose (Invoice 2). Once they replaced the positive battery cable the issues went away. - I did research on the NHTSA Safety database and it looks like this has been a problem for ~400,000 BMW vehicles over the last ~15 years. See references: SIB 61 06 17, SIB 61 09 18, SIB 61 11 19, SIB 61 14 12 - The vehicle has not been inspected by the manufacturer, police, insurance representatives. It was brought into an independent service center - There were warning lamps and other symptoms that showed up after the instrument cluster started flickering while driving (that was always the first sign). I attached screenshots of those warnings.

I was driving along the road and my car without warning overheated. I was able to drive to a safe place and park and contacted BMW of Southpoint Durham, NC. I was told that there was a recall on the hose which caused the car to overheat. I was told that they are waiting for BMW to issue the corrected/replacement hose for the car and in the meantime they would put a temporary hose on the car. I was told to pay out of pocket and then be reimbursed when the correct hose is issued by BMW. Many others had this same issue. BMW of Southpoint received the correct hose 2023 and put it on my car but now BMW is saying there was no recall. My safety and others were at risk because the engine could have caught fire, it could've caused me to lose control and crash. I had to sit on the side of the road for hours and could've been hit by another vehicle. Vehicle was inspected by BMW of Southpoint. There were no warning signs. lamps or messages prior to the car overheating. This happened February/March of 2022. Since then I was told letters had been sent out for a service update.

My husband bought a BMW through the military sales program, had it delivered to the United States, and we took it with us to Germany where we currently live. The car is made to U.S. specifications and I had been driving the car weekly in Germany to keep the battery running while he is away on a deployment. On April 11, 2022, as soon as I pressed the ignition button, the dashboard flashed a strange indicator light which I didn't have time to examine because my attention was immediately diverted when a metal bar next to the right rear headrest deployed from inside the seat and punched through the windshield. It sounded like someone threw a brick into the car. The check engine indicator also lit up but deactivated after a few minutes. According to the owner's manual, the metal bar is one of a set of two rollover protection rods which are designed to deploy in the event of a sufficiently serious accident or if the car's longitudinal axis is tilted excessively (i.e. if the car flips over). But there was no accident... All I did was turn the car on. The car remained in park the entire time. We can't find any evidence of this type of misfire occurring with this model car. The car is currently in the shop for repairs after being towed to a local BMW dealership. They investigated the incident, wrote me an email saying they did not notice any technical defects, and refuse to pay for repairs or take responsibility for this incident. Something like this is dangerous and should not happen at all. I think it meets recall criteria, and I definitely think BMW should pay to fix it.

I was rear ended. My airbag did not deploy. I do not think my seatbelt restrained me because I was not sore in that area, but do not remember. My head hit the stearing wheel. I spent 3 months in a neuro-recovery program and still deal with post-concussive syndrome. The car is available for whomever would like to see it. I incurred a closed head injury with significant effects. No one has tried to reproduce the issue, and I'm actually scared that if there is a problem and another accident it's like I don't have airbags. I went to the BMW dealership and they just said that my VIN was not under a recall and I would have to deal with BMW legal for any further information. The car has been repaired from the rear end collision. There were no warning lights or anything. Other than this, I love the car. I want to make sure that if anyone in my family is driving and is hit their head will be protected from the steering wheel. the doctors have told me that if I get another concussion it could be devasting. Please let me know how to proceed. Thank you.

I HAVE DRIVEN THE CAR NOW ABOUT 900 MILES. AT NO TIME HAS THE FRONT END COLLISION/PEDESTRIAN WARNING SYSTEM GIVEN ME ANY WARNING EVEN THOUGH I HAVE NEARLY REAR-ENDED THE CAR AHEAD AND EVEN THOUGH I HAVE IT SET FOR THE EARLIEST WARNING POSSIBLE. BMW N.A. ASSIST CUSTOMER CARE STATES THAT I SHOULD RECEIVE BOTH VISIBLE AND AUDIBLE WARNINGS BUT ALSO STATES I HAVE TO RELY ON WHAT DEALER SAYS. THE DEALER- DREYER & REINBOLD - STATES THE SYSTEM IS WORKING AS IT SHOULD. THIS CANNOT BE TRUE. SINCE MY 2015 BMW 535I HAD A PROPERLY WORKING FRONT END COLLISION WARNING THAT FREQUENTLY APPEARED ON MY INSTRUMENT PANEL AND HEADS-UP DISPLAY, I KNOW HOW THE SYSTEM IS SUPPOSED TO WORK. THE CURRENT CONDITION OF MY VEHICLE CREATES A SERIOUS SAFETY HAZARD AND I DON'T KNOW WHERE ELSE TO TURN. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).' *PM
