When it fails

Odometer readings owners gave when they filed. About half of all complaints include one.

When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2018 BMW 328D

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

2 investigations are still open.

EA23001 Opened 17 Mar 2023 Still open FUEL SYSTEM, DIESEL:DELIVERY:FUEL PUMP

High pressure fuel pump failure

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a compreh...

EA21002 Opened 17 Sep 2021 Still open AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

Desiccated Air Bag Inflator Rupture

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

POWER TRAIN

While driving down the road my car gave me a notification “DRIVETRAIN MALFUNCTION” said full engine output not available then it just stopped and shut off (limp mode) it has done this multiple times and the shop says that it may be the High Pressure Fuel Pump. This has happened on a busy city road with high traffic and curvy roads where my car would not move and people could not see me when coming over the hill until last minute narrowly missing my car. Luckily there wasn’t oncoming traffic. I had to switch ignition off and on (it then said “transmission not in park”) when it was in park. Finally started back after having to shut ignition off and on twice. Then anytime I got above 40 it went back into limp mode.

FUEL/PROPULSION SYSTEM

In 2021, my vehicle had the high-pressure fuel pump replaced by an authorized BMW dealership under Safety Recall 21V-586 (BMW SIB 13 01 21). At the time of the recall, my vehicle had approximately 43,000 miles, and I was not experiencing any fuel system or drivability issues. The high-pressure fuel pump was replaced solely because BMW determined the original component posed a safety risk. My vehicle now has approximately 128,000 miles. The replacement high-pressure fuel pump installed as part of the recall has failed. Two independent repair facilities have diagnosed the high-pressure fuel pump as the cause of the no-start/fuel delivery issue. When I took the vehicle to a BMW dealership, I was informed that additional diagnostic work was needed to inspect for possible metal contamination from the fuel pump, but I have not yet been provided with a final written diagnosis. I am concerned that the replacement part installed as the recall remedy has failed in the same manner as the original recalled component. If confirmed, this raises concerns about the durability and effectiveness of the recall repair. I respectfully request that NHTSA review whether similar failures have been reported involving replacement high-pressure fuel pumps installed under Recall 21V-586. I am submitting this complaint so the issue can be documented and evaluated as a potential safety concern.
