2013 BMW 328i, N20 engine. Timing chain guide assembly and oil pump drive chain failed catastrophically. Vehicle is available for inspection, however the authorized BMW dealership has already made clear they will accept no responsibility, and I would bear the expense of towing it two hours to their facility. The failure is a known issue with a class action case, but BMW took no responsibility, and falsified information stating the vehicle showed no signs of an issue when I brought my vehicle in for inspection. Eighteen months before failure, steam came from the engine compartment on a humid day, later connected to the water pump electrical connector recall. Following this, the vehicle ran consistently hotter than normal and lost noticeable power. Twelve months before failure, an intermittent oil pressure warning began triggering under load at highway speeds, particularly on inclines above 70mph. I brought the vehicle to Sandia BMW in Albuquerque, NM and reported all symptoms when I was contacted by them for the recall. The service advisor falsely claimed elevated operating temperature was optimal, suspected a faulty sensor, and returned the vehicle without offering further diagnosis or making me aware of the impending issue, all classic signs of the engine faults. Eight weeks later, the oil pressure light activated on a highway, followed immediately by a drivetrain malfunction warning, a violent grinding sound, and complete loss of power. The vehicle was towed and has not restarted since. I contacted BMW of North America's recall line. A case was opened and an advocate stated BMW would accept no responsibility because the class action was closed and I'mpast 70K miles. I raised the dealership's direct culpability. The advocate stated a dealership representative would contact me. No call was ever received. This failure is consistent with BMW Service Bulletin SI B11 03 17. A engine safety recall is warranted regardless of age to protect the public.

INCIDENT SUMMARY: On January 9, 2026, at approximately 1:30 PM, while traveling at 50 MPH in North Carolina, the vehicle experienced a sudden, catastrophic engine seizure without any prior "Limp Mode" warning or Check Engine Light. This resulted in an immediate, total loss of motive power in active traffic. I was forced to navigate a dead multi-ton vehicle across lanes without power steering or vacuum-assisted braking, narrowly avoiding a high-speed collision. TIMELINE & NEGLIGENCE: This vehicle was purchased from an independent retail dealer on December 20, 2025—less than 21 days prior to this life-threatening failure. The vehicle was sold with an "Open" status for Safety Recall 23V-707. The failure occurred exactly as described in the recall’s warning: a catastrophic stall at speed. TECHNICAL EVIDENCE: A non-invasive borescope inspection of the cylinders has confirmed the presence of metallic "silver chunks" (sheared bolt heads) and "half-moon" impact marks on the piston crowns, indicating a total timing failure and internal mechanical collision (piston-to-valve contact). REQUIRED REMEDY: This incident is a direct manifestation of the safety risk documented in Recall 23V-707. Per BMW Service Bulletin SIB 11 09 23, the presence of sheared bolt heads and seized internals constitutes "Catastrophic Consequential Damage." I am filing this report to ensure federal oversight of BMW North America’s obligation to provide a complete engine replacement, as the safety defect was present at the time of sale and resulted in a near-fatal incident within 300 miles of ownership.

Virtually all parking brake cable attachment clips fail on this BMW product years 2012 to 2019. Complaints are easy to find online. Upon failure, the parking brake cable drops down onto the drive shaft creating a safety hazard for the brake system as well as the drive shaft mechanism. The piece that fails (breaks) costs less than $20, but replacement costs $1200 due to labor intensive access. I have repeatedly contacted BMW of North America, but they refuse to own this serious issue. Even the people at the BMW dealership here are surprised that there has been no recall. Please advise.

Engine coolant pump recall (August 2024) with no remedy to this day. Has caused major smoking issues from exhaust and engine. The turbocharger has been affected and deemed inoperable. Fluid leaks from chassis and engine bay. The car is inoperable. Prior to being unable to drive I was experiencing transmission issues, went for a few repairs but would experience the car coming to a complete stop on its own at highway speeds. Experienced this on the bridge, being left stuck and almost causing a wreck. Made the bridge very unsafe for others. I had a “drive train malfunction” warning& check engine light that I thought was fixed with multiple mechanic trips but problems have only gotten worse. No inspections have been done in regards to the recall. The car has sat unable to drive for 2 full months now.

The parking brake cable bracket is a cheap piece of plastic that fails on every single BMW model like mine from this era, which means the parking brake cable comes in contact with the drive shaft. Mine has broken. Dealers charge $1,100 to replace with an equally cheap 30 dollar plastic bracket. Replacement is labor intensive which explains the high fee (I guess). BMW mechanics as well as BMW owner internet forums tell me that this fails on every single car. This is a real hazard, as it can cause parking brake failure and drive shaft damage. Owners are very upset with BMW for not taking care of this obvious design flaw. My car has all of 52,000 miles on the odometer. This needs to be a recall!! BMW refuses to take care of this, just as they have refused to take care of the existing water pump recall. Thanks in advance for taking care of this safety issue.

I recently brought my 2011BMW 328i in for recalls and a shutter noise. My vehicle is equipped with the N51 SULEV motor. I recently was not able to set monitors for smog due to a shutter issue. I was told by a reliable mechanic it was the torque converter, and it is covered under the SULEV warranty. I was shocked when Bob told me that the torque converter was not covered under BMW SULEV warranty. It clearly states that in the SULEV warranty and my car only has 123,000 miles. He proceeded to call my car "a can of worms" and told me the technician simply does not want to work on my car. I know for a fact my Torque Converter and Mechatronik are covered under the SULEV warranty. I was simply kicked to the curb. This is unethical and my car is not passing smog due to this issue which is illegal. Please help resolve my issue.

I was driving and my car began to lose power and Drivetrain Malfunction appeared on the screen. I had to pull over to a side street and turn the car off. I turned it back on but it was very sluggish and moved very slow. Once I parked it I turned it off and tried to start it back up but it wouldn’t turn over. I contacted BMW and they said they couldn’t do anything. I need a new engine and timing chain, fuel pump and oil pan.

Check Engine light is illuminated. VANOS exhaust warning codes are stored. Other vehicles with the same N52 engine are subject to recall 23V707. BMW indicates that this vehicle is not included but could be in the future. In the interim, we are faced with a $3500 - $4500 out-of-pocket expense (which will probably never be reimbursed) or the possibility of the events described in the recall, which include a crash. For the safety of drivers of other vehicles in this same series with this same engine, it is imperative that the recall be extended to all potentially affected automobiles.

I own a 2015 BMW 328i xdrive with 86k miles. While reversing out of my driveway, onto a main road during rush hour, my vehicle unexpectedly stopped working with the message “drivetrain malfunction”. I had the car towed to a BMW dealership and was told there was a fault found in VANOS intake and that my car needed a timing chain replacement. I called BWM NA and was informed that there is a VANOS recall, but not for my car. They did however tell me that BMW would compensation for timing chain repairs for my 2015 328i if the car fell within certain parameters, low miles and within 7 years. While my car has low miles, I was told that my recall for the part had been “cleared” because I’m outside of the 7 year allotment for compensation on timing chain repairs. BMW will not help fix the timing chain nor compensate in anyway. I was informed they sent a letter in 2017, I purchased the car in 2017 and did not receive a letter. My vehicle had been serviced multiple times at BMW dealerships and I was never informed about a timing chain recall, not even in 2018 when my car was serviced at BMW for check engine light on. BWM has purposely avoided fixing a major vehicle flaw that they’ve known about.
