2017 BMW 330I Problems

The cooling system is continually failing prematurely. Parts that should be lifetime are needing to be repaired below 100K miles. I have had to repair the following cooling system related items that should be under recall and are not Oil filter housing Thermostat housing Turbo coolant lines Water neck the cost of repairs is significant and BMW is denying responsibility for the premature failures.

The Oil Filter Housing (OFH), the Coolant/Water Pump, and other plastic lines for the cooling systems are well known to fail with this engine early in their lifetime. My service advisor at BMW said, "these are very common issues for a B46 engine.". The Motor Mounts also are extremely prone to failure due to the use of the Auto Start/Stop feature. This has also been noted by my service advisor at BMW. They commented, "these cars come in often before ever hitting 20k miles and needing replacement. I recommend never using the Auto Start/Stop feature ever again.'

During normal street and highway driving operation, the whole console and digital warning systems shutdown causing safety issues while driving.

When I was driving on suburban roads with speed limit of 45 mph, I received a waring from my vehicle saying "engine high temperature, drive moderately". After sometime, it said "engine overheated stop carefully". During the first warning, I felt loss of acceleration power and during the second warning I felt completely no power in acceleration that too when I was yielding for a left turn which was life threatening, luckily the oncoming traffic slowed down. Otherwise I would have ended up in life threatening crash. During both warnings, I checked the engine temperature gauge in the instrument cluster and the engine temperature was not even 50% of the maximum temperature in the gauge. After the warning, I slowly made it to a nearby parking lot and opened the hood and did not physically feel any excessive heat for an engine not to function. I regularly service my vehicle and my vehicle is not due for any kind of service for the next 2000 mile as per the onboard vehicle status. The next day I started the vehicle to help it to climb the tow truck ramp and at that time, for the very first time I received a warning saying engine coolant is very low. I have never received this warning since I have owned the car until then. I have two concerns, 1. The temperature gauge did not show a high temperature, only 24 hours after the electronic engine high heat notification, the low coolant warning came in which is weird and my vehicle isn't due for any service. 2. None of the above should result in a sudden loss of acceleration power which could have resulted in a fatal crash in my case. I'm a mechanical engineer with a strong background in automotive occupant safety (airbags/seatbelts) and that's why I see this a very serious incident that needs to be looked into so that it doesn't occur for anyone else in the future.

I received a warning on the dashboard that the tires needed inflating and that I should not drive the car over 80 miles per hour. When this happened the communication system on the car failed. I could not use the telephone or the direction feature. I do not know if other parts of the car also failed. When the tires were re inflated, these other features returned. This has happened twice. (In addition the tires needed reinflating on one or two other times.) BMW offers a courtesy service to reinflate the tires so that they don't maintain a record of the problem and they are unable to add a note to their service record to document the problem.

Passenger restraint system malfunction just came out of the blue. In the morning it was fine, in the afternoon when I went out to my car it threw this error. Other cars in the 5 and X series with the sport seats I have were also recalled for this same issue, but there is no recall for my car. Please help!

After day to day use the seat belt stopped functioning. The mechanism to lock the seat belt is stuck and will not unlock to latch the seat belt properly. Ultimately the driver and passengers are unable to latch the seat belts at anytime.

We had a 2017 bmw 330i x-drive. It had approximately 67000 miles. The car stalled while driving about 6 times. The first time was in 3/2021. The diagnostics were for a faulty high pressure fuel pump. We replaced the HPFP. It stalled again while driving. The diagnostics were for a faulty low pressure fuel pump. We replaced this. The car then stalled while driving 2 more times. The car stalled again in 10/2021, and we towed it to the dealer, who diagnosed a problem with the electric fuel pump control unit., which the dealer replaced. We brought the car home for one day, and we had the same problem again. We brought the car back to the BMW dealer, who diagnosed a problem with the VANOS system. The BMW Peabody dealer directed us to BMW corporate for evaluation of available warranties and rebates given the nature of the problem (VANOS) being warranted under the California SULEV emissions standards and the fact that they dealer had diagnosed a separate problem the day before. We sent the diagnostics and the SULEV warranty info to Sean, as everyone at BMW seemed unaware of its existence and who was responsible for following it. He took weeks “looking into it,” and the dealer repaired the VANOS during this time without a final answer from corporate. A car stopping while driving is clearly dangerous to the occupants and surrounding vehicles. BMW did not honor the SULEV warranty, which clearly covers the VANOS and the fuel pumps until 70000 miles. The car was traded to BMW Peabody, as we no longer felt safe driving it. We do not know if the replacement of the VANOS fixed the problem.

Water pump keeps going bad 2nd time replacing in 2 years rough idle and failed part problems that BMW service team does not understand. Vehicle has stalled at 0 rpm I'm thinking there is an issue with the engine also reported by previous owner and I also have the same complaints, as well the foot release which I was was told was an option never worked. Please search vin [XXX] for all incident reports with this vehicle. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

DRIVING AT 40MPH AN ALERT ERROR FOR STEERING AND BRAKING WARNING CAME UP AND STALLED THE CAR TO ZERO MPH. A REVIEW OF OTHER INTERNET COMPLAINTS ON BMW OWNERS WAS SIMILAR. WHY IS THIS NOT A RECALL?

I WAS DRIVING BETWEEN 55-65 MPH ON A TWO LANE HIGHWAY WHEN THE PANORAMIC SUNROOF SPONTANEOUSLY EXPLODED. THE MAJORITY OF GLASS BLEW UP AND OUT OF THE CAR, BUT SMALL PIECES WERE FALLING BACK INTO THE CAR. THE TEMPERATURE OUTSIDE WAS APPROXIMATELY 66 DEGREES. TRAFFIC WAS MOVING WELL, BUT HEAVY.

There is a well known issue with the clip on BMW 3 series (mine is a 2017 330i) that holds the parking brake cable assembly to the body if the car above the drive shaft towards the rear of the car. The plastic clips fail frequently, causing the parking brake cable assembly to fall and the brake lines rub against the driveshaft creating a metal-to-metal noise. Over time the friction between the drive shaft and parking brake cable will eventually create failure of the cable in my opinion. I have this issue and I have seen several online videos of others who have the same issue.

Upon investigation, the contact discovered NHTSA Campaign Number: 19V074000 (Exterior Lighting); which the contact linked to the failure. The dealer was notified of the failure and the contact was informed that there were no recalls on the VIN related to the failure. The vehicle was not repaired. The dealer referred to the contact to the NHTSA Hotline to report the failure. The manufacturer was not notified of the failure. The failure mileage was unknown.
