Battery problems, was supposedly recalled for it and now the car is dying and the alarm is going off in my driveway at 10:30pm after being off for hours. The alarm doesn’t turn off with the fob or if key is in ignition, I need to remove the battery panel find a ratchet and remove one of the battery terminals while my alarm is simultaneously going off for long period over and over and over.
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.
My BMW drivers seat get so hot it feels like it's about to catch fire ( I don't have heated seats } sometimes in motion sometime after I shut ti off.
Went to replace my front headlamp bulbs after headlamp failure while operating my vehicle at night, on a winding road, in rural texas. Mechanic pulled the "sealed" housing, and discovered that the majority of the wires in the headlamp assembly had faulty insulation. The insulation had "flaked" off to the point that many of the wires were exposed, causing a short circuit, and failure of the headlamp. Researched the issue on many forums, and it is a common occurrrence. Replacement costs of each headlamp assembly is approx $1500. The use of subpar insulation appears to be the cause of this safety issue.
The wires in the head light assembly are brittle and break upon just touching them. Causing day time running lights to fail as wires are bare and touching each other. This is also a fire hazard.
We would like the NHTSA to be aware that myself and a few colleagues own BMW and have experienced this issue. BMW has purposely built these vehicles to fail after the warranty period when a few months after the 100,000 mile warranty we began having problems specifically with the seals around all all windows including windshield and rear window as well as the seals around the trunk, however at the bottom of the trunk BMW keeps a main component board underneath the spare tire , once the seals begin to fail it causes water and moisture to gain access to this compartment and cause the board to ignite and catch fire and cause car to go crazy with acceleration and deceleration, why place a main component in this location with 10 feet of extra wire and no drain, I would also like to point out all BMW's of the same year experience m melting of the plastic interior parts and the paint to completely break down underneath the clear coat no matter how much ax is applied these are major flaws and BMW is well aware of them, there vehicles and service is terrible they should not be allowed on the road.
The car beeps every few miles and a warning light shows it need an oil change, I had just gotten a change, so they changed it again, the next day the bells started ringing again. Also the gear shifter went out. It is still ringing.
Bought the car in Aug started using the seat warmer about December of 2014. Here and there upon using I'd smell something burning so I would turn it off! but not all the time when using the warmer did I smell burning! late March my husband noticed a burn hole on my driers seat, I instantly remembered the burning smell when sometimes using the seat heater! I'm lucky I was not burned but my driver seat is ruined and I'm now afraid to use the heaters, ever!.
2007 BMW 525xi model not limited to or exclusive of this make/model but has a known issue where a red light indicator appears on the dash signaling an electronic steering column fault has occurred, do not turn the engine off or the car may not be able to be started again, contact your local BMW service department. This has yet to make it on the NHTSA database as an official recall but I have researched and made note of several hundred customers experiencing this same issue on their BMW. This car is out of the 3 year service warranty and this is not a covered or recalled item as of today. I am filing my complaint against BMW since it will be costing me over $1000 to have this addressed/fixed when in fact it is abnormal behavior by BMW engineering/manufacturing and is a defect in their design. It should be recalled and fixed for all BMW customers covering the span of years in which the commonality has occurred 2006-2007 325, 525 models.
