Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

October, 9, 2024 BMW USA Customer Relations, Recall Services Ms. Ikevia, Thank you following up. My 2021 claim regarding the 2011 BMW Z4 Vanos Bolts recall has been pending since April, 2021. My Z4 almost destroyed itself, after having been left off your recall list. December, 2023 BMW USA provided me written notice my VIN had been added to the recall list so I will be reimbursed for the costly repair. I hope you will help your colleagues who are stonewalling to appreciate my patience as well as my willingness to fight for reimbursement for as long as it takes You do have all my information in your Vanos Bolts Recall file, including detailed photos from my Syncro Car Care professionals who did the repair when you declined to help me. My VIN which is: [XXX] - 2011 Z4 3.0 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have written to you previously to advise of repeated engine issues with my vehicle, a 2011 BMW Z4. I also included invoices of work that was done over time to correct a likely Engineering flaw that caused excessive fuel injector failure. In 2021, there was a 10 year extended warranty to replace them. Prior and after the warranty work, there was almost constant engine misfires and engine warning lights resulting in decreased engine performance, and low oil lights that came on every 300+ miles driven. My recent issue with the car involves a starter quitting while driving at 70mph on [XXX]. It was terrifying. It's impossible to put into words that death was imminent. On [XXX], we were traveling to Orangeburg, SC when the car suddenly "died" on the highway. Once we recovered from our shock, we had the vehicle towed to a local shop. The owner advised us that it needed a new starter. Once that was replaced, the car started with a severe screeching noise. After further assessment, it was determined that there was a bent piston rod and that the engine would have rebuilt or replaced. I, a former automotive Engineer, believe that there was an inherent design flaw that caused the car to excessively use oil. Interestingly, I purchased a new BMW and as a condition of sale, was required to sign a document that I would not sue BMW or participate in a class action lawsuit. I was not provided with a copy of the form that was signed, but doubt that it would be upheld in court. BMW needs to be held accountable for their products and their performance.

We received notice of this recall, and while the Manufacturer administratively states there is no remedy, they then list the remedy quite simply which is to replace the Vanos Bolts. I called around to dealers and other Euroshops and every one of them has the parts to remedy the recall. Because of this it is clear that both the remedy and parts required for this recall is in fact available. Given this information this means BMW is either negligently prolonging listing the remedy as available or worse, purposely doing so in order float money that they do not yet want to shell out to dealers to fix these recalls. I have contacted BMW customer relations and while they do not dispute that the parts to remedy this recall are readily available, they refuse to administratively list the recall remedy as available. They refuse to offer to replace or refund the vehicle as well. This is a violation of federal law and our rights as a consumer, whereas the manufactures must proceed in a timely fashion and while they are granted time to develop a remedy and procure the parts needed, there is no part of the law that allows them to unilaterally administratively refuse to list the remedy as available when in fact the remedy is available as are the parts to repair it readily available. Resolutions we will accept on this matter are exactly what is required by the manufacturer by law. Correctly list the recall remedy as available so we can have it remedied at a dealer, and if BMW refuses to do that, they are violating our rights to repair this in a timely fashion and must either replace of refund.  Please assist on this matter thank you so much

In Sept. 2018, the car was serviced but died after leaving the BMW service center. BMW paid for towing after discovering a frayed ribbed v-belt, which they replaced at no cost. In Nov. 2021, the oil gauge was indicating a problem and the car was then serviced at the same BMW service center. The technician was shocked to find broken pieces of an old drive belt stuck in suction tube. They took a video and then replaced the leaking oil pan gasket and gasket rings. Despite the risk of serious bodily harm or death if the engine had suddenly failed on the highway, BMW service center could not explain how pieces of the old drive belt got into the suction tube. They could not tell us that this problem would not happen again. This problem is not limited to BMW; however, at least one other car manufacturer has taken steps to prevent this problem.

MY BMW Z4 2011 STALLED FOR THE THIRD TIME. THIS HAPPENED IN A PARKING LOT AS MY CAR WAS SLOWING DOWN. THE ENGINE SHUT DOWN COMPLETELY AND I HAD NO POWER STEERING. I TOOK MY VEHICLE INTO THE DEALERSHIP THE NEXT DAY FOR SERVICE AND CONTACTED BMW USA. I PURCHASED AND INSTALLED A DASH CAMERA AND CAPTURED THE STALLING ON THE THIRD INCIDENT AND PROVIDED THEM THE FOOTAGE. BMW USA DID A VISUAL INSPECTION AND CLAIMED THAT MY AFTER-MARKET LED LIGHT BULB IN MY DAYTIME RUNNING LIGHTS WAS THE CAUSE OF MY STALLING WITHOUT PROVIDING ANY DOCUMENTATION OR TESTING. BASED ON THEIR CONCLUSIONS, THEY VOIDED MY ELECTRICAL AND POWERTRAIN WARRANTY AND DENIED ANY REPAIRS TO BE MADE BY ANY BMW DEALERSHIP PER BMW USA. THERE IS A DEFINITE ISSUE WITH THIS VEHICLE STALLING THAT BMW CANNOT RESOLVE AND THEY HAVE RESORTED TO BLAMING THE CONSUMER WITHOUT PROPER TESTING OR DOCUMENTATION. *TR

MY CAR STALLED AGAIN ON JULY 26TH. IN THIS INSTANCE, I WAS ON THE FREEWAY DRIVING ON THE ON-RAMP BETWEEN 5-10 MPH. MY CAR STALLED COMPLETELY, HOWEVER, THIS TIME THE ELECTRICAL WAS STILL ON. I PANICKED BECAUSE I WAS STILL MOVING IN TRAFFIC. THANK GOD I WAS ABLE TO BREAK IN TIME AND RESTART MY CAR ON THE FIRST ATTEMPT BECAUSE I COULD'VE GOTTEN INTO AN ACCIDENT VERY EASILY WITH CARS DIRECTLY IN FRONT AND BEHIND ME. I WAS TOLD AT THE LAST SERVICE THAT ALL RECALLS WERE COMPLETED ON THE VEHICLE. SPECIFICALLY THE BATTERY CABLE WHICH CAUSED MANY PREVIOUS Z4 TO STALL RANDOMLY. THE STALLING IS STILL OCCURRING ON THIS VEHICLE AFTER THE RECALL. *TR

THE CAR STALLED FOR THE FIRST TIME. I WAS DRIVING FOR ABOUT 5 MINUTES AT AROUND 25-35 MPH AND MADE A STOP AT A TRAFFIC LIGHT. WHILE AT A COMPLETE STOP, THE CAR ENGINE AND ALL THE ELECTRICAL SHUT OFF COMPLETELY WHILE IN GEAR. I PUT THE CAR INTO 'PARK' THEN TRIED TO RESTART. IT DID NOT START THE ENGINE BUT THE ELECTRICAL CAME BACK ON AND THE YELLOW CHECK ENGINE LIGHT APPEARED. AFTER TWO ATTEMPTS (TAKING KEY OUT, PUTTING KEY IN, AND STARTING THE ENGINE), THE CAR STARTS AGAIN AND EVERYTHING WENT BACK TO NORMAL. *TR
