What owners said

2001 BMW 525I Carrollton, GA

ELECTRICAL SYSTEM

We arrived at church, and I remained behind finishing my makeup. My husband locked the car with the fob out of habit, and my foot was holding the passenger door open. Forgetting the door had been locked with the fob, I accidentally allowed the passenger door to close. I had no keys. Services began, not a soul in site outside. I began to panic when I could not get the door or any other to open. The alarm would not trigger, and the sunroof was cracked accidentally about an inch. It was July. I could not get anyone to hear me, and could not get any door or window ajar. Eventually I was able to get the attention of an elder, who went and retrieved the keys and got me out. I was soaked in sweat, using an inhaler about every 20 minutes, extremely scary. The other time this happened, my son was sitting in the car but the alarm went off and would not let him out until I came with the fob. He was 15, so he was not young. I had no idea he could not exit the vehicle should he choose. I know there is some emergency release in the hatch somehow but could not locate. Air bags were scheduled to be replaced, had rental scheduled with dealership, drove 45 minutes to leave car for repair, but they had no rental as was promised, so I returned home in the vehicle.

2005 BMW 525I Perris, CA

ELECTRICAL SYSTEM

I am encountering persistent issues with my 2005 BMW 525i. Despite having replaced several critical components, including the ignition coils, spark plugs, mass air flow sensor, and throttle body sensors, the vehicle continues to experience performance problems, specifically failing to advance beyond the fourth cylinder when driving uphill. After conducting numerous diagnostic tests, I have concluded that there may be an air leak in the intake manifold. Additionally, after prolonged use under these conditions, the positive battery cable from the trunk has shown signs of overheating, evidenced by smoke, which I suspect is related to repeated uphill driving. While the vehicle performs adequately on flat surfaces, it exhibits hesitation and jerking once it surpasses the fourth cylinder.

1995 BMW 525I West Chester, PA

ELECTRICAL SYSTEM

RECAL 94V219000: Double-lock Feature GCM Revised. "The double-lock feature can engage with occupants and the door/ignition key inside of the vehicle. The occupants of the vehicle would be unable to exit either from the doors or from the windows of the vehicle." NOTE: IF YOUR VEHICLE IS PRESENTED TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND THE REMEDY IS NOT PROVIDED FREE OF CHARGE WITHIN A REASONABLE TIME OR THE REMEDY DOES NOT CORRECT THE DEFECT, CONTACT BMW AND THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE My car locked me in it and I was unable to exit exactly as described in this Recall. Called BMW and they are saying the recall was remedied. Clearly it is not corrected. BMW says they cant do anything. 1995 or not this is a serious safety issue, this car is perfectly safe running and driving vehicle besides this issue.

2007 BMW 525I Charlotte, NC

ELECTRICAL SYSTEM

I purchased said automobile from my neighbor for my son to drive. I figured it was a good car to buy because it was serviced by Hendrick BMW (Charlotte, NC) only and regularly. BMW's also have a reputation for being safe as well as reputable so this also weighed into my decision. Fast forward 18 months. The passenger rear brake bulb went out. We replaced the bulb, it worked for a short time, then went out. We replaced the bulb again. This time it didnt work. About a week later the front passenger side head light went out, then the other side. We took it to Hendrick BMW for repair. Hendrick has told us the car wiring basically needs to be replaced due to the protective coat wearing off and corroding the bare wire underneath. The headlights/ brake light will also need to be replaced due to the corrosion blowing out the bulb. For the front headlight the whole assembly needs to be replaced at a tremendous cost. I performed a google search on this and found many, many instances of the same issue. Ive seen many of these cars while casually driving around town. It would seem to be a MAJOR issue if an active drivers head and tail lights suddenly stopped working on a busy road. Also due to the cost most people probably wouldnt fix the issue on their own and drive the car anyway causing an ever bigger safety issue. I have never had this issue with any other vehicle brand ive owned. Ive looked into this issue with other brands and most tell me they use wiring which will not do this. I am not sure why BMW would not do the same. The car is also up for inspection. The car will not pass inspection unless I pony up over $6k ($2500 NADA value) to fix. My taxes are also due. In NC you cant pay the tax unless the car passes inspection. This is costing me daily penalties in addition to the major safety issue. I believe the NHTSA has a duty to look into this major manufacturing defect and have BMW provide remedy to those other unfortunate folks who are experiencing the same issue.

2003 BMW 525I Sacramento, CA

ELECTRICAL SYSTEM

I was driving and antitheft system went off while driving. Then wiper failed to work. I was told by dealer mechanic that the body control module was failing and advised not to drive the car because the antitheft system may cause the car to stop and the wiper system will stop when raining causing multiple accidents.

2001 BMW 525I at 160,000 miles Galt, CA Fire

ELECTRICAL SYSTEM

I HAD TAKEN A LONGER ROAD TRIP, AND WAS ON MY WAY BACK, ABOUT A QUARTER OF THE WAY WHEN WE STOPPED FOR DINNER. I PARKED, AND EVERYTHING WAS USUAL. A COUPLE MINUTES LATER, I WENT TO MOVE THE CAR, AND WHILE I WAS WAITING IN A DRIVE-THRU LINE, I SEE SMOKE BILLOWING OUT FROM UNDER THE HOOD AND I SMELL A BURNING SMELL. I PARKED THE CAR BACK WHERE IT HAD BEEN, AND, THINKING IT WAS A COOLANT ISSUE, OPENED THE HOOD TO LET THE ENGINE COOL DOWN, AND LEFT MY PASSENGERS WITH THE CAR AND WALKED ACROSS THE STREET TO BUY SOME COOLANT. WHEN I RETURNED, MY PASSENGERS TOLD ME THAT THEY HAD NOTICED A FLAME AT THE EXTREME FRONT OF THE ENGINE AND HAD TO DOUSE IT WITH WATER. I CHECKED, AND I SAW THAT THE WIRES LEADING TO THE AUXILIARY COOLING FAN IN FRONT OF THE RADIATOR HAD MELTED AND CAUGHT ON FIRE AND BURNED THE PLASTIC NEAR THEM (AS SEEN IN THE PICTURE). I THEN FOUND THE CONNECTOR FOR THOSE WIRES AND DISCONNECTED THEM SO THAT THEY COULD NOT RELIGHT. I DID SOME RESEARCH AND FOUND THAT THIS IS A COMMON PROBLEM RESULTING FROM THE WIRES PULLING TOO MUCH POWER AND THUS MELTING THEMSELVES. THE PROBLEM WITH THE WIRES DID NOT SET OFF ANY WARNING OR CHECK ENGINE LIGHTS, AND DID NOT AFFECT THE ENGINE TEMPERATURE, AT LEAST AT FREEWAY SPEEDS. I ALSO FOUND OUT THAT THE BATTERY CAN RUN THIS FAN FOR UP TO 11 MINUTES AFTER THE ENGINE IS TURNED OFF, THUS BEING ABLE TO START A FIRE IN A GARAGE WHEN NO ONE IS AROUND. THIS PROBLEM IS EXTREMELY DANGEROUS AS THE WHOLE CAR COULD GO UP IN FLAMES.

2006 BMW 525I at 180,000 miles Lagrange, GA Fire

ELECTRICAL SYSTEM

I WAS ON MY WAY TO WORK AND HAD DRIVEN ONLY 4 1/2 MILES AT 6:55AM ON THURSDAY, AUGUST 15, 2019. I WAS ABOUT 1/2 FROM WORK ON A CITY STREET WHEN SMOKE BEGAN COMING OUT THE AIR VENTS AND STEERING COLUMN. A SMELL OF PLASTIC, ELECTRICAL FILLED THE CAR AND I PULLED INTO THE NEAREST PLACE WHEN THE SMOKE WAS QUICKLY INCREASING. MY SON AND I JUMPED OUT OF THE CAR AND CALLED 911. THE FIRE DEPARTMENT ARRIVED ALMOST IMMEDIATELY, AND UPON PULLING UP, BEFORE THEY COULD GET OUT OF THE TRUCK, THE DRIVER'S SIDE CURTAIN AIRBAG EXPLODED, THE FIREMEN HEARD THE EXPLOSION. BY THE TIME THEY PULLED THEIR HOSES AND LIFTED THE HOOD, SMOKE WAS HEAVILY COMING FROM THE CAR. WHEN THE AIRBAG EXPLODED, A LARGE PIECE OF PLASTIC SHRAPNEL WAS BLOWN TO THE PASSENGER SIDE OF THE CAR AND STUCK BETWEEN THE WINDSHIELD AND THE WINDOW AND STUCK INTO THE EDGE WINDSHIELD FRAME. THE FIREFIGHTERS TRIED FOR SEVERAL MINUTES TO GET THE SOURCE UNDER CONTROL AND FINALLY WAS ABLE TO WHEN THEY DISCONNECTED THE BATTERY. I HAD MY CAR TOWED TO BMW COLUMBUS, THEY "REPAIRED THE RECALL" AND SAID THAT THE FIRE WAS NOT A RESULT OF THE RECALL. I BELIEVE THAT IF THE FIREFIGHTERS DID NOT RESPOND AS QUICKLY AS THEY DID BECAUSE THEY WERE NEARBY, THEN MY CAR WOULD HAVE GONE UP IN FLAMES.
