"I am reporting a failed safety remedy by BMW of Macon regarding Recall 13V‑044 (Battery Cable Connector). Following the recall service, the vehicle suffered a systemic digital failure and a legal odometer discrepancy of approximately 20,000 miles 73,547 to around 53,000k (The 53k miles was seen on the dash after the service, but the exact number wasn’t documented by me, but was reported to my service advisor at BMW of Macon) Specifically: 1. Module De-Sync: The recall was allegedly performed without proper voltage stabilization, causing a communication failure ('brownout') between the CAS and Instrument Clustermodules. 2. Vehicle Immobilization: The resulting digital handshake failure has triggered a security lockout, rendering the car unable to crank and locking the transmission in Park (No Neutral). 3. Misdiagnosis: The dealership is refusing to reconcile the software corruption they caused, instead attempting to charge for a mechanical starter motor that was fully operational (CAS 1/1) prior to their intervention. This vehicle entered the dealership for a safety recall and was returned in a digitally compromised, legally unmarketable, and non-operational state. I request a federal investigation into the dealership's failure to provide a safe and effective remedy."

As of recently I've been smelling a gas smell after driving my vehicle. No matter the distance or time I smelled the odor of gas. I am a certified automotive technician, so I decided to diagnose the problem myself. I put my vehicle in the air and spotted a wet spot of gas on the bottom left side of my fuel tank. To continue my diagnosis process I googled to see if anyone dealt with a similar issue. Seen a decent amount of people confirming the problem. A leak from the D/S fuel sending unit. So I take off my rear seats, and takeoff the fuel sending unit cover. Once the cover was off seen multiple cracks along side top of the unit. No warning lights was present, however did notice MPG was getting worse and worse. the little cracks makes my vehicle a fire hazard. I was able to have the replacement part ordered for about $140.

The engine and all electrical components including power steering spontaneously cutout while driving, usually while engine isnt being stressed at all, sometimes while idling. If the car is rolling, i have to restart the engine while driving and using manual power to steer. Obviously, this is a huge safety problem. I've just had the alternator and battery replaced, and they test fine. This has happened at least 50 times and I've reduced time driving vehicle until I solve the issue, which has persisted at least 6 months. I asked the BMW dealer about the following recall, and they claim they already performed it years ago after I already owned the car, without my recalling being told it was done. However, the symptoms are back, and BMW refuses to do anything about it at this time: Report Receipt Date: FEB 07, 2013 the federal safety agency Campaign Number: 13V044000 Component(s): ELECTRICAL SYSTEM Potential Number of Units Affected: 504,545 All Products Associated with this Recall Details 2 Associated Documents Manufacturer: BMW of North America, LLC SUMMARY: BMW is recalling 2007-2011 3-Series sedans manufactured March 2007 through October 2011. The connector for the positive battery cable connector and the corresponding terminal on the fuse box may degrade over time. Over time, the high current flow and heat from electrical resistance may lead to a breakage of the connection, and a loss of electrical power to the vehicle. CONSEQUENCE: If there is a loss of electrical power to the vehicle, the vehicle may unexpectedly stall, increasing the risk of a crash. REMEDY: BMW will notify owners, and dealers will replace the positive battery cable connector and secure it with an improved method, free of charge. The recall is expected to begin in March 2013.

I am experiencing a know issue others have complained about related to the high pressure fuel injector failure in my vehicle. There have been previous recalls for this and my vehicle should fall within the recall dates and is showing all of the symptoms of this failure yet is it some how not part of the recall. What is happening is on cold starts or even idle the car is shaking and has a very apparent misfire, I have checked the spark plugs and they indeed have fuel on them. The injectors are causing excessive fuel in the cylinder this leads to a host of problems that are potentially, catastrophic like the engine seizing while driving due to oil dilution from the fuel

When I arrived at my destination, I was unable to unlock the front door of my car and exit. I could not unlock it either manually or electronically. The unlocking mechanism failed. I had to roll down my window an reach outside to the door handle. Evidently the manufacturer was aware of this problem because it repaired it by installing an "updated door latch on both front doors." I am gratetfull that I did not have to get out of that car because of an emergency.

I was told by my mechanic my fuel injectors have gone bad and I believe this is from a manufacturer's issue. Please investigate as I know various people that have the same issue with the same engine, year and make. I took it to the shop after I turned it on to drive and the vehicle was shaking a bit more than normal, when I accelerated the car was very vaguely responding to me. This is why my vehicle began to misfire, because of the fuel injectors. I will keep all receipts until further notice of this issue.

01may2020. Brought 2008 bmw 335i to south atlanta bmw dealership to replace rear brake pads (based on inspection report from a jan2020 appt). It was determined that: 1. Oil filter housing gasket: filter housing gaskets & oil cooler o-rings leaking oil 2. Radiator hose replacement. Upper coolant hose turning brown and seeping. 01may2020. Radiator hose was replaced along with conducting brake fluid flush and micro filter. Same day after repairs were complete the car stalls and shuts off and becomes unable to drive. Car is towed back to dealership for further inspection. Upon further inspection the following are identified: 1. Fuel pump replacement: r&r high pressure fuel pump & low pressure sensor per fault code 29f2 2.turbocharger - variable boost control solenoid: both vanos solenoids & oil change per sib. Dealership informs me that the fuel pump's warranty has been extended 10 years/120000 miles due to manufacturing issues with the fuel pump. I have never been made aware of issues with the fuel pump or extended warranties for replacing. I do think I should be responsible for repairs on a malfunctioning fuel pump that was poorly manufactured. Bmw should be responsible for the replacement and repair.

The key fobs in the 2008 bmws are glued and the battery soldered into place, making it difficult for owners to replace the batteries in the key fobs when the battery dies. Once the key fob battery dies, the vehicle is inoperable. Bmw should offer a replacement key fob for all model years where the battery is not able to be changed by the owner.
