2017 BMW 3 Series

Diesel fuel pump failed while driving on the road. I also own a 2014 328d BMW which was recalled earlier where the diesel fuel pump was replaced by the dealership. While driving on the road, the car unexpectedly turned off in traffic. I managed to get the vehicle off the road and called a tow truck. I contacted my local BMW dealer and informed me my 2017 328d is not under a recall like my 2014 328d was. I then instructed the tow truck driver to take the car to an independent mechanic who specializes on BMWs. The diagnosis is a fail fuel pump.

Component: Engine Cooling System: Turbocharger Coolant Return Line/Fitting (Part # 11538854735). Defect Summary: The factory turbocharger coolant return line on the B48 engine uses a plastic quick-disconnect fitting and O-ring mechanism positioned directly under the turbo. Extreme thermal cycling causes this plastic to degrade, become brittle, and fail or separate without warning, resulting in immediate, catastrophic drainage of pressurized engine coolant. Failure of Manufacturer Requirements: This component fails basic durability, material safety, and engineering standards for pressurized cooling systems. The design is so fundamentally flawed that authorized factory-trained technicians cannot permanently remedy it using OEM parts; the connection mechanism fails to maintain a pressurized seal under standard operational heat. Freeway Safety Incident: While traveling at high speeds in high-velocity freeway traffic, the fitting failed catastrophically without warning. The sudden coolant loss forced an immediate engine stall/power failure in active lanes. Navigating the powerless vehicle out of the middle of the freeway while surrounding traffic swerved nearly caused a severe, high-speed multi-vehicle collision. Inadequate Remedy & Recurrence: The vehicle was taken to an authorized dealership (BMW of the Woodlands, TX) for repair. However, within one week of dealership service, the new OEM line/O-ring completely disconnected again. This recurring separation completely drains the coolant within days, causing subsequent engine stalls, rendering the car undrivable, and repeatedly placing occupants in extreme danger. Thermal & Fire Hazard: Each failure sprays pressurized coolant onto a hot turbocharger and exhaust manifold, creating immediate risks of blinding smoke, vision obscuration, and engine bay ignition, compounded by thermal risks to the 330e hybrid powertrain battery electronics.

Hybrid battery has a failed cell. It was confirmed by BMW diagnostics but BMW refused to repair/replace failed cell even though it was under full 8yr/80k mile warranty. BMW claimed it as wear and tear, even though 1 out of 5 cells completely failed. The failure caused the car to run at reduced speeds causing others cars around me on the freeway to be in danger as all of sudden I am unable to reach freeway speeds due to part failure. There was an error stored in the car per BMW diagnostics that called for failed Cell to be replaced per notes of the technician who ran the diagnostics. The vehicle was inspected and confirmed by BMW. Yes, there was an error on the infotainment of the car. I advised of the error to BMW.

Unsure of the exact cause, appears to be the high voltage battery/electric drive function that is faulty. It is creating a hazardous condition causing the vehicle to propel itself forward while driving in traffic and almost hitting other vehicles on the roadway when the electric drive fails or it switches between battery and the engine. If it’s not propelling itself forward, it’s unexpectedly decreasing power and preventing the vehicle from driving after stopping for traffic, traffic signals and traffic signs. Increasing the risk for a rear-end collision. The electric drive is failing & rapidly switching between battery & engine multiple times in a short period. Likely increasing risk for a fire hazard. This is putting the driver & others on the roadway at risk due to increased collision and fire risks. Ferman BMW has recreated the issue. They advised it needed 2 new batteries, standard and the auxiliary battery. Those were replaced and the vehicle still is having issues. Six replaced 3 times. They now blame it on the high voltage batteries & their age. HV batteries are covered under warranty, yet Ferman BMW states they are not because there’s no fault code. Their position is the electric drive malfunction message is a notification & not a fault code. Despite duplicating the issues, having notice of the hazard they refuse to fix it. The message states “ Electric drive is temporarily restricted. You can continue driving. After cooling/heating of high-voltage battery full electric drive power will immediately be available.” A brief search will reveal many others with the same issue and some were successful in getting it handled under warranty. The car has been inspected by Ferman BMW 6 times. This is an ongoing issue with this model and a hazard to the driver, passengers and others on the roadways.

The contact owns a 2017 BMW 330I. The contact stated that the rear driver’s side taillight cover loosened and detached but was able to be put back in place. 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.

My BMW has had multiple repairs (3 incidents - 2 times repaired by BMW and 1 time repaired by a national mechanic garage) to the coolant system since I purchased it in 2018. BMW have verified the leaking coolant as well as the independent garage. Currently, the coolant system has another on going issue where it is still leaking and it's still unable to be fixed. This coolant issue has had catastrophic failures at times and more recently it has thrown a major engine overheating warning that has impacted the safety of my wife, kids and I as well as other individuals on the road as I have had to pull over quickly and turn the car off to allow the engine to cool down. I've had to drive the car at a reduce speed and acceleration which has frustrated many drivers causing them to over take me dangerously. Additionally, I've burnt my hand from opening the coolant expansion tank to add coolant on multiple occasions.

The contact owns a 2017 BMW 320i. The contact stated that while his son was driving 35 MPH after an oil change was performed on the vehicle, the message "Engine Temperature High. Drive Moderately to Cool Engine. Consult Service Center" was displayed. The vehicle was towed to the same independent mechanic, where an unknown diagnosis was made. The vehicle was not repaired. The vehicle was towed to the dealer, where it was diagnosed that the water pump electrical connector and wiring were corroded, fractured and needed to be replaced. The vehicle was not repaired. The vehicle was then towed to another dealer, where it was diagnosed that the water pump and the electrical connector needed to be replaced. The contact related the failure to an unknown recall. The manufacturer was notified of the failure. No further information was available. The failure mileage was approximately 94,000.

I noticed coolant leaking from under the vehicle. The message to add coolant was displayed. The vehicle was taken to an independent mechanic where the engine was inspected, and was notified of stains of coolant coming from the head gasket. The contact was informed that the head gasket needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. I believe this is failure is related to NHTSA Campaign Number: Recall 18V755000, October ,24 2018, My car has only 73000 Miles

The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was unknown.

Oil filter housing and or oil cooler failed. Leaking internally and externally. May cause fluid to leak on to hot engine and cause potential fire or short circuit wiring.

UNKNOWN, it has problems with stalling and starting up could be issues with the internal drive system that I’ve seen other types of similar models of bmw having these recall issues as well. When starting up after fueling up it over exerts the engine trying to start up. You kind of have to rev it to start it up. And driving it after that it has trouble keeping a solid drive.
