2000 BMW 328CI

Subject: Urgent Safety Concern — 2000 BMW 328 Ci — Error Codes P1622, P0304, P0301 — Second Airbag Recall 21V-401 — Request for Engineering Investigation BMW of North America, LLC 300 Chestnut Ridge Road Woodcliff Lake, NJ 07677 May 9, 2026 
RE: 2000 BMW 328 Ci (VIN: [insert VIN]) — Multiple DME Fault Codes — Second Airbag Recall (21V-401) — Suspected Electronic Interference 
To the Office of Customer Relations and Vehicle Safety: I am writing to formally document a serious safety concern regarding my 2000 BMW 328 Ci, which is currently subject to the second airbag recall in this vehicle's history (Takata NADI recall 21V-401). The vehicle is exhibiting diagnostic fault codes in the DME (Digital Motor Electronics) that indicate possible electronic interference with the engine control and safety systems. 
Diagnostic Evidence — May 7, 2026 On May 7, 2026, a professional BMW diagnostic scan (iSCAN S/N 70EB2) revealed the following active fault codes in the DME: 1. P1622 (MAP cooling activation fault) — Present. This code indicates a communication fault between the DME and the EWS (immobilizer) system. In my research, this code is consistent with RF interference on the DME/EWS communication line.
 2. P0304 (misfire cylinder 4) — Present and continuous. The misfire on cylinder 4 is persistent and does not respond to component replacement.
 3. P0301 (misfire cylinder 1) — Present and intermittent. The misfire on cylinder 1 is also persistent but less frequent.
 
Component Swapping Test — Critical Finding The technician performed a component swapping test: * Spark plugs and ignition coils from cylinder 1 were moved to cylinder 3
 * Spark plugs and ignition coils from cylinder 4 were moved to cylinder 6
 * Result: The misfires remained on cylinders 1 and 4. They did not move to cylinders 3 or 6.
 This test conclusively rules out the spark plugs and ignition coils as the cause of the misfires. The cause is upstream — in the DME module itself, or in the wiring/signal path

PLEASE SEE ATTACHED PDF. DOCUMENT FOR A FULL EXPLANATION. THE SUB-FRAME ON MY BMW 3 SERIES (E46) HAS FRACTURED AND BECOME SEPARATED FROM THE CAR. THE DETACHED SUB-FRAME IS NOT CAUSED BY ANYTHING I DID, BUT IS THE RESULT OF AN INHERENT DEFECT INVOLVING THE VEHICLE'S SUB-FRAME, A MAJOR COMPONENT OF THE CAR'S STRUCTURAL SYSTEM THAT SUPPORTS THE POWERTRAIN AND IS WELDED TO THE CHASSIS. I WAS NOT AWARE OF THE DETACHED SUB-FRAME UNTIL I HEARD A METAL ON METAL SQUEAK IN THE REAR OF THE CAR; AS TIME WENT ON, THE DETACHED SUB-FRAME RIPPED THROUGH THE REAR TIN UNDERLAYMENT/SHIELD AND THE TWO ARE NOW RUBBING TOGETHER. THE DEFECTIVE SUB-FRAME IN THE BMW 3 SERIES E46 MODELS POSES A RISK TO MOTOR VEHICLE SAFETY, AS IT IS A 'CRITICAL VEHICLE COMPONENT' OF THE CAR. FURTHER, A QUICK INTERNET SEARCH WILL PROVE THAT THIS DEFECT IS HIGHLY PERSISTENT IN THE E46 BMW 3 SERIES. AND IN ACCORDANCE WITH U. S. CODES FOR MOTOR VEHICLE SAFETY, 'CRITICAL VEHICLE COMPONENTS THAT BREAK, FALL APART, OR SEPARATE FROM THE VEHICLE, CAUSING POTENTIAL LOSS OF VEHICLE CONTROL OR INJURY TO PERSONS INSIDE OR OUTSIDE THE VEHICLE,' A RECALL IS IN ORDER. PLEASE NOTE THAT I DON'T KNOW "WHEN DID THIS HAPPEN?". I JUST PUT THE DATE I HAD MY SUB-FRAME INSPECTED BY A CERTIFIED BMW DEALER (SEE ATTACHMENT FROM COLLISION CENTER OF ORLANDO). I HAD MY SUB-FRAME INSPECTED WHEN I HEARD A LOUD SQUEAKING NOISE. AS I UNDERSTAND IT, OWNERS WERE UN-AWARE THEIR SUB-FRAMES WERE DEFECTIVE; DISCOVERY WAS MADE BY A THOROUGH MECHANIC OR BY CHANCE. MY SUB-FRAME TORE THROUGH THE TIN UNDERLAYMENT/SHEILD, SO THE METAL RUBBING METAL IS WHAT WAS CAUSING THE SQUEAKING NOISE. AND AS I UNDERSTAND IT, THE SUB-FRAME TEARS THROUGH THE TIN UNDERLAYMENT ONLY AFTER BEING UNDETECTED FOR A LONG PERIOD OF TIME. THIS IS SO DANGEROUS NOT ONLY TO ME BUT OTHER DRIVERS. BMW NEEDS TO BE HELD RESPONSIBLE. A RECALL IS IN ORDER.

WHILE DRIVING DOWN THE ROAD, A LOUD METAL TO ROAD NOISE STARTED TO EMANATE FROM THE BOTTOM OF MY VEHICLE. AFTER PULLING OVER AND EXAMINING THE UNDERSIDE OF MY VEHICLE, I COULD SEE THE FUEL TANK STRAP ON THE RIGHT SIDE OF THE VEHICLE DRAGGING AGAINST THE GROUND AND THE FUEL TANK HANGING DOWN FROM ITS NORMAL POSITION. THE STRAP HAD SEPARATED FROM ITS FRONT RETENTION POINT. A THOROUGH INSPECTION REVEALED THAT THE FRONT MOUNTING BRACKET FOR THE FUEL TANK STRAP WAS NO LONGER ON THE VEHICLE. THE BRACKET HAD SEPARATED FROM THE VEHICLE. THIS BRACKET APPEARS TO BE SPOT WELDED TO THE FRAME. IN THIS CASE, METAL WAS MISSING FROM THE FRAME AT THE WELD POINTS AS IF THE WELDS WERE INTACT BUT THE METAL AROUND THE PERIMETER OF THE WELDS HAD YIELDED AND FAILED. THIS APPEARS TO BE A METAL FATIGUE ISSUE OF THE FRAME SURROUNDING THE WELD POINTS OF THE RIGHT SIDE, FUEL TANK STRAP, FRONT MOUNTING BRACKET. THIS VEHICLE HAS BEEN LOCATED IN PHOENIX SINCE NEW AND HAS NO SIGNS OF RUST OR OPERATION INDUCED DAMAGE TO THE FRAME OR STRUCTURE IN THIS AREA. *TR

I AM NOTIFYING THE NHTSA THAT BMW HAS ADVISED ME THAT MY CAR'S PASSENGER AIRBAG NEEDS TO BE RECALLED AND REPLACED UNDER THE 14V-428 RECALL CAMPAIGN. HOWEVER, THEY ARE UNABLE TO PERFORM THIS REPAIR, THEY ESTIMATE, FOR MONTHS. I AM THUS FORCED TO RENT A CAR FOR LONG ROAD TRIPS, SUCH AS FOR THANKSGIVING AND CHRISTMAS, BECAUSE MY FAMILY MEMBER REFUSES TO RIDE IN THE CAR. I HAVE PRESSED BMW TO PROVIDE A REPAIR OR A LOANER OR RE-IMBURSE FOR A RENTAL, AND THEY REFUSED ON ALL THREE OPTIONS. *TR

I OWN A 2000 BMW 328 CI. IT ALSO HAS HAD A REAR END SUB FRAME FAILURE THAT THEY HAVE BEEN FOUND AT FAULT FOR BY THE STATE OF CA IN A LAWSUIT DATED IN 2006. I BROUGHT MY CAR TO THEIR ATTENTION AND THEY ADMITTED THIER FAILED DESIGN, AND BECAUSE SOMEONE HAD TO TRIED TO REPAIR IT BEFORE THEY SOLD IT TO ME, OF COURSE WITHOUT INFORMING ME ABOUT, THEY REFUSED TO DO WARRANTY WORK ON IT, BECAUSE A FEEBLE ATTEMPT AT REINFORCING A FAILED SUB FRAME MOUNT. FAST FORWARD TO NOW, THEY OFFERED ME 2000 DOLLARS ON A 6100 DOLLAR REPAIR BECAUSE THEY HAVE ADMITTED FAULT. NOW THEY RE-NAGGED THEIR OFFER, BECAUSE RATHER THAN DOING IT THEIR WAY, I HAD THE MOUNTS UPGRADED WITH BETTER STEEL AND MOUNTS RATHER THAN USE THEIR FAILED DESIGN. THEY CONTINUE TO TELL ME THEY ARE DOING ME A FAVOR, WHEN IT IS THEIR FAILED DESIGN IN THE FIRST PLACE, WHICH THEY ADMIT TO. WHEN IS IT A FAVOR FOR BUYING A CAR THAT HAS A FAILED FRAME DESIGN, AND HAVING THE COMPANY NOT TAKE RESPONSIBILITY FOR IT WHEN THE FAILURE COULD BE THE REAR END FALLING OUT, AS HAS OCCURRED TO MANY PEOPLE, AND SOMETHING THEY ADMIT TO. THIS IS VERY DANGEROUS, AND ALSO GOES AGAINST EVERY TYPE OF DESIGN ETHICS THOUGHT TO EXIST. WHEN COMPANIES FAIL ON THIS CALIBER, IT HAS THE SAME POTENTIAL TO KILL SOMEONE FOR SOMETHING THEY KNOW NOTHING ABOUT. *TR

The basic conditions for initializing the power windows are not met.

Diagnosis of Compound Brake System Complaints in M Vehicles: 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form.

SERVICE ACTION - HEAD AIR BAG HOLDER RETROFIT: A rattle noise may develop from the head air bag (ITS) gas generator contacting adjacent component. This noise can be heard while driving on an uneven roadway.
