FAQs—BMW 550i XDrive
I own a BMW 550i XDrive for two months now, and I can't believe that I'm already having a couple of issues with it. The passenger's restraint system failed, and I already called up my dealer to have the wiring harness replaced. I also got worried because there have been airbag warnings every now and then, and I had to bring my vehicle to the dealer for repair. I'm starting to become frustrated with my car when I found out that my sunroof controls were also not working. It only has 5,000 miles on the odometer, but I think I've brought the car to the dealer for more than 20 times now. What should I do?
It seems like your new car is actually a lemon. A lemon is a car that has been found defective only after you've bought it. Lemons are usually brought back to the dealer for full replacement. What you need to do is to bring your vehicle back to the dealer, and have it replaced. When this happens, you may choose not to get the same model, or even the same brand, once the car has been identified as a lemon. If you've spent at least 30 days in the shop, then it's really up for a full replacement.
Since last week, my BMW 550i XDrive has been idling and running roughly. I panicked when the drivetrain malfunction warning flashed. I've already experienced that last year when my car only has 21,000 miles. Back then, I replaced my O2 sensor and all the eight fuel injectors. I don't know what causes this problem. I want to fix it once and for all to keep it from recurring again. What should I do?
Maybe there's something wrong with the new fuel injectors that you replaced. Make sure that they are compatible and that they adhere to the suggested specifications and brands of the manufacturer, as indicated in the owner's manual. You might also need to check if the gaskets and seals fit the injectors perfectly. If not, then it can be causing the problem.
I was driving on my way home, when my vehicle just got a ‘replace battery' warning. My car is only six months old, and this is the first time I've experienced this. I wonder the battery of my car is really up for replacement, or is there just something wrong with the warning mechanism. What's going on?
You may need to bring your vehicle to your trusted mechanic to have the problem diagnosed. It could be due to a problem in the electrical system, wherein your car may be drawing too much power than it should be. Upon diagnosis, your software might need to be upgraded. If you don't usually use your car, you might consider locking it when it is parked at night to keep your battery from getting drained. You may also try getting a trickle charger for your battery. If all else fails, you might need to have your battery replaced.
