BMW 3 Series Reliability by YearBest & worst years, problems & recalls — NHTSA data

car had 1,645 miles rear left axle broke. Car would not move. Had this occurred on a highway I easily could have been rear ended. Part must have been defective, Dealer replaced the part left rear CV joint but not the right, nor did the dealer confirm both rear axles were not from the same batch. The failure was catastrophic and sudden with no warnings.

Car just shut off when driving at 65mph and never started back up, took it in and repair was a bad fuel pump and fuel rail line causing metal shards to go through fuel tank and injectors.

Was simply driving my vehicle to work. It started overheating parked it right away before it got worse as the car alerted had it towed to a shop. The shop informed me that the motor was blown in the pistons went through the motor something with the oil the mechanic and I were looking further into this and it looks like my make and model in year had some recalls about the motor overheating in the past so I would really like this looked into as this might be a recall I’m not sure what else this could be or why this would happen with such low miles

My 330i 2018 bmw has a cracked in the oil housing unit. This is due to bmw putting plastic parts instead of aluminum. After researching this I found thousand of people complaining about the sane thing. The car overheats and sometimes the oil gets mixed into the coolsnt system b causes more damage. This seems to happen on cars with mileage between 60-70 on engines B46, B48 n B58z

The contact owns a 2018 BMW 330E. The contact stated that while driving at an undisclosed speed, there was an abnormal squealing sound coming from the engine compartment, with the check engine warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 55,000.

Oil Filter Housing failed and coolant gushes all out which makes the car undrivable and risk of engine overheating and failure.

The contact owns a 2018 BMW 330I. The contact stated that while driving at various speeds, the engine overheating message was displayed on the instrument panel with the temperature gauge rising to hot(H). The vehicle was taken to an independent mechanic where the coolant reservoir was topped off however, the failure persisted. The contact then received notification of NHTSA Campaign Number: 21V907000 (Fuel System, Diesel) which was linked to the failure. The vehicle was taken to the dealer where the recall repair was performed. The contact stated that recently the vehicle began to leak coolant. The vehicle was taken back to the dealer and the contact was informed that the manifold needed to be taken off to perform a diagnostic test. The contact was informed that the oil filter housing unit and the water pump both needed to be replaced. The manufacturer was notified of the failure and transferred the contact to the NHTSA Hotline to report the failure. The vehicle remained in the possession of the dealer unrepaired. The failure mileage was approximately 60,150.

The contact owns a 2018 BMW 328D. The contact stated while driving 50 MPH, the vehicle started shuddering significantly. The contact was able to pull over and the check engine warning light illuminated. The vehicle was towed to the contact's workplace. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and informed the contact that there was no record of a recall on the VIN. However, the contact stated that he received notification of NHTSA Campaign Number: 21V586000 (FUEL SYSTEM, DIESEL). The vehicle remained at the workplace and had not been driven since. The approximate failure mileage was 102,000.

The vehicle gave a warning that the engine coolant was low and to power down before it overheated. Upon taking it to the dealer, it was discovered that the oil housing unit was defective. After doing online research, this is a very common issue with this part. I had a previous vehicle with a similar issue that caused the vehicle to shut down in traffic from overheating.

The contact owns a 2018 BMW 330E. The contact stated while driving at 60 MPH, the vehicle hesitated, stalled, and restarted independently. The vehicle was taken to a dealer where it was diagnosed that the starter needed to be replaced.  The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 24V576000 (ELECTRICAL SYSTEM, ENGINE AND ENGINE COOLING), however the VIN was not included in the recall. The failure mileage was 103,000.

My passenger airbag sensor malfunctioned and the repair is over two thousand dollars. The car is only 6 years old and I believe airbags should last longer than 6 years. BMW has extended warranties for airbags on some models (mine not included) for 15 years without mileage limitation. If a collision occurs, my passenger would be in extreme danger.

On 12/03/2024, while traveling at approximately 35mph, the "top off coolant" light came on. After traveling for approximately 10 more minutes, in route to get coolant, a warning message came on the screen advising to drive cautiously to prevent engine scorching. The vehicle then began to slightly lose power while traveling on a busy road. The vehicle was then shut down and towed to BMW dealership. During the tow, it was discovered that coolant was leaking from the center area of the engine block. The manufacturers dealership service rep advised that the technicians discovered that the oil filter housing needed to be replaced. They also found that the coolant pump also needed to be replaced. The rep advised that the coolant seal on the oil filter housing had worn down and caused the coolant leak. He also advised that the coolant pump needed to be replaced, as it was also leaking. It was later discovered because the valve that the pressure propelled, hot coolant flows through in the oil filter housing is made of plastic, it often wears down and coolant leaks out heavily. The water pump is also effected by the part manufacturing issue. In addition to receiving a $4,270.42 invoice for repairs today, we just recently purchased the $199.00 BMW Vehicle Check Service from the dealership on 9/23/2024. At that time, we were advised there were no issues with the vehicle. We have sense learned that there have been multiple recalls on various BMW models for this exact same issue. However, the VIN on my vehicle has not yet been identified for recall. Had this issue gone on for mere moments more, the engine could have caught fire, and or, a catastrophic crash could have ensued, effecting any driver on the road.
