Always get the message: right break light. I have changed the lightbulb several times and the break light fails to work. Sometimes it works and sometimes it stops working. I believe this is common problem based on you tube videos and postings on the internet. How can it be fixed?

Drivetrain malfunction light came on stating to drive moderately. Maximum drivetrain output not available. Consult service center. The codes was cda904 no message (status trailer 0X2E4) receiver engine ECU transmitter trailer. 130F20 exhaust camshaft offset angel to crankshaft outside tolerance; 120408 boost pressure control, cut off pressure rise block after paying $180 for diagnostic I was told today that I need to replace the timing chain/ guild. Replace oil pump chain module and replace the valve cover. The timing chain guide is broken. This is crazy my car has 88000 miles and is not paid for. The cost to get this repaired is approxmiately $6,000. There is a current class action lawsuit. BMW knows that this is a problem but refuses to do a recall. The plaintiffs take issue with two specific defects in the engine's chains. The first defect affects the primary chain, also known as the timing chain, which coordinates the action of the crankshaft, camshafts, and cylinder valves. According to the plaintiffs, the plastic guide assembly for the primary chain is made of a defective polycarbonate material that becomes brittle and breaks apart, creating debris that lodges in the crankshaft drive sprockets. The debris can cause the primary chain to skip, letting the camshafts and crankshaft fall out of sync and possibly damaging or destroying the engine. The second defect affects the secondary chain, which connects the oil pump and balance shaft assembly to the crankshaft. The materials in this assembly can't stand up to high-resistance wear, the plaintiffs say. This defect causes the chain to elongate prematurely, slip, and damage the chain sprocket.

Purchased the vehicle in late March. We have already had to go to the repair shop more than 3 occasions. I believe they are using faulty pieces in vehicles. We spent 13K and put down 4K. Now working 2 months the repairs are costing close to 5K in 2 months. I understand buying used vehicles as my first car was used. However I have had no issues in 2 years. I believe this piece was broken and they didn't want to repair the issues with the car based on cost.

Door locking mechanism I starting to fail. At times it is impossible to open a door from the inside because of the door lock actuator when the rest of the car is unlocked. Currently, the only method to unlock it would be from the key or the door unlock button in the center of the vehicle. This could be dangerous in situations where one would need to exit the vehicle but they cannot because the door will not open.

The door lock actuators have failed. This makes it so that the doors do not open when you are inside the vehicle attempting to get out by pulling the door handle. This is a safety issue not allowing me to get out of my vehicle. If this issue is not resolved by paying the $1500 to fix the issue the doors will stop opening completely making this even more of a safety issue over time. This issue only gets worse and is directly related to the functionality of the car. This door lock actuator should be recalled on all vehicles BMW makes that are having this same issue. This is a known long-standing issue with these vehicles and has yet to be recalled even though it is absolutely a safety issue. BMW should not be able to profit off of their poor safety manufacturing mistakes.

The vehicle was going down a hill (straight forward) on a ca city street when the driver shifted from auto to manual gear. Instead of working as expected, the car underwent a sudden acceleration and braking proved ineffective. Through a couple seconds of attempted braking with no response, the car kept on accelerating instead. Finally, after making two turns on the hill, the car spun completely out of control and swerved to the other side of the street where it crashed through five trees and eventually stopped. The driver loss of consciousness and delivered to er. The weather condition was good. The failure mileage was 79,541. Policy report filed.

Driver and passenger trapped in car after parking at as gas pump. Doors would unlock but not open resulting in the potential of killing its passengers in a crash. There is a video on youtube of a similar incident.

- Bradford, NH, USA

The driver and passenger doors occasionally do not unlock from inside the vehicle, trapping me inside. Pressing the unlock button in the dashboard works, but pulling the physical handles does not.

The contact owns a 2013 BMW 328I. The contact stated that the coolant warning indicator illuminated. The contact added coolant, but the indicator remained illuminated. The vehicle was taken to an independent mechanic who diagnosed that the electrical sensor failed. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact to take the vehicle to a dealer. The dealer was not contacted. The failure mileage was approximately 125,573.

Rear left brake light and turn signal stopped working. I have checked and found out that the ground wire on the connector has over heated and broken.

When I try to open the drivers side door by pulling the handle it does not unlock automatically. The only way to exit the vehicle is through another door or by using the central lock/unlock button. My fear is that in the case of an emergency or accident if the electrical system is compromised I could possibly be trapped in the vehicle. I attempted to have this repaired at the BMW dealership but they claim that the problem being mechanical is not covered by the warranty. On the BMW internet forums there are multiple posts across vehicle models complaining of the same faulty "door actuator" and BMW's unwillingness to repair it free of charge. I was quoted over $950 to replace the part. This is a serious life safety issue I believe needs to be investigated. Thank you very much!

I have taken my car to the dealership and asked for this lock issue to be repaired at least 6 times during the past five years. Over the past two years the issue happens more frequently. At times I am in the car without it running, then I go to open the door and I am locked inside. The handle acts like it is going to open but the door does not open. The handle lifts but does not move the lock. I have to use a button on the console or the key fob to unlock all the doors electronically. I find this not safe because if the automobile does not have electric supply the drivers door needs to be able to open. This concerns me if there was a accident or urgent need. I had some other suspension issues that I reported. You could hear a loud sound and I was told for a over year it was not a issue. Finally my husband was going to come to the dealership and they said they found the problem did over $6,000 in warranty repair on a faulty boot part before the warranty expired. I had the problem for a long time! BMW diagnostic and service is not what it used to be.

Light cracks, chips, defects inside of headlight housing. Vehicles are not that old and the defect tends to appear on all F30 BMW 3 series models. Could worsen over time and create visibility issues.

While driving down the road, the car's idrive system spontaneously rebooted. The system will often take several minutes to reboot (sometimes the system will reboot again directly after regaining connectivity or while trying to reboot). We had already been driving for about 30 minutes when this happened the first time. It has happened many times since. BMW has tried to fix the issue but has not been able to. They have replaced the head unit, idrive screen, and the combox, all with no resolution. The idrive system is responsible for communication with the driver for the car's status including tire pressure and oil level (there is no manual way to check the oil). In addition, this system controls the low jack communication, road side assistance and all bluetooth capabilities (hands free driving is required in most our state) in the automobile.
