2000 BMW 328I Problems

What owners report

Owners of the 2000 BMW 328i most often report two very different problems: rear subframe and floor-pan cracking around the rear mounts, noticed as a squeak, clunk or pop from the rear, and a sudden loss of reverse gear in automatic cars. Many complaints also concern air bag warnings, unwanted air bag deployments and unfixed Takata recalls. Complaints cluster between roughly 50,000 and 180,000 miles, so condition and service history matter more than age alone.

   Body and structure

   Rear subframe/floor pan cracks at rear mounts

   • 26 complaints (23%)
   • median 119,000 mi at 12.0 yrs old (24 state mileage)
   • filed 2004–2018

   Owners describe a squeak, clunk or popping sound from the rear that gets worse over time, sometimes followed by a loud bang and a jolt while driving or shifting. Shops and dealers reportedly find cracks, torn metal or separation where the rear subframe and differential mounts attach to the floor pan, and owners say the car can become hard to control. Several owners mention hearing about a prior class action and that inspections done earlier found nothing, yet the metal later tore. Mostly reported between about 50,000 and 170,000 miles, often after driving over potholes or during ordinary street driving.

   What to check: Have a shop inspect the rear subframe mounting points and floor pan from underneath with the car on a lift, and listen for rear-end squeaks or clunks on a test drive. Ask whether the car was ever inspected under the earlier BMW program and whether any reinforcement or repair work was done.

   “While driving on the on the freeway I felt and heard a popping or clunck noise while shifting like something was going to fall off and it became hard to control and steer so I took my 2000 328I Bmw into a professional mechanic and he said the problem is the subframe is separating from the body of the car, I was also told this is a manufacturer defect. …”

   NHTSA complaint #11128381, filed 2018-09, 118,000 miles

   “I was driving 20 MPH and accidentally hit a pot hole in the road. After doing so the 2000 Bmw 328I drove normally. However after this incident I began to hear a clunking noise in the rear area of the vehicle every time I put the vehicle in drive. I took it to the repair shop for an analysis and was told there is a tear in the subframe. …”

   Transmission and drivetrain

   No reverse gear (automatic transmission)

   • 23 complaints (21%)
   • median 128,261 mi at 9.5 yrs old (18 state mileage)
   • owner-quoted repair $5,000 (median of 7 quotes)
   • filed 2007–2016

   Owners report that reverse simply stops engaging, sometimes intermittently and sometimes for good, while forward gears continue to work; in one case the car rolled forward instead of backing up. Some describe warning signs such as transmission indicator lights, slipping at highway speed or a need to restart the car. According to complaints, dealers and shops often found nothing wrong or quoted several thousand dollars for a transmission rebuild or replacement. Reported from roughly 50,000 to 190,000 miles, with many around 100,000 to 150,000 miles.

   What to check: On a test drive, shift into reverse from a stop several times, including when the car is cold, and confirm it moves under its own power. Ask whether the transmission was ever rebuilt or replaced and whether any warning lights appear.

   “My 2000 Bmw 328I reverse gear just went out. When I put it in reverse to back up there is no power. I rev the engine and it doesn't move at all. I had to put it in neutral and push it to get out of a parking spot today. I have read thousands of people with the same problem with the same year of Bmw cars. The solution is to replace the transmission which runs 4-7 thousand dollars, ridiculous.”

   NHTSA complaint #10264844, filed 2009-04, 101,901 miles

   “I parked the car and when I got back in to drive away, I couldn't back up after putting it in reverse. Engined revved but would not move. I had to push car out of parking space. Dealer wants $ 5000.00 to fix, what they say is a common problem with 2000 Bmw 328I's.”

   Air bags

   Air bag warning light on / sensor under passenger seat

   • 7 complaints (6%)
   • median 102,500 mi at 13.0 yrs old (6 state mileage, few)
   • filed 2004–2020

   Owners describe the air bag warning light staying on, sometimes repeatedly after repairs, and dealers pointing to a sensor or mat under the passenger seat or to a control module. Some complaints note that the light returned even after a replacement, and owners were quoted several hundred dollars for the repair. Others mention being told the vehicle was not covered by a recall while a recall notice had been received. Reported across a wide range, from about 50,000 to 188,000 miles, often noticed at startup.

   What to check: Turn the ignition on and confirm the air bag light goes out after the bulb check, and scan for stored air bag codes. Check with a dealer whether any Takata inflator recalls were completed on the vehicle.

   “The air bag system on my 2000 Bmw 328I has failed (red warning light on) 3 times. Although the red light has been on, my wife and I always drive with our belts fastened and due to the nature of the problem (two times it has required returning the vehicle a second time due to availability of replacement parts), we have opted to drive with the light on until the next scheduled vehicle service. The last time the air bag failed we were charged approximately $500 for the repair. This repair was october 2004. …”

   NHTSA complaint #10102906, filed 2004-12, 46,000 miles

   “Air bag light stays on. As per the Bmw dealership, sensor under the passenger seat is faulty and it will cost $800/- to fix it. In the event of an accident, air bag will not deploy unless the issue is resolved. This poses a significant safety issue.”

   Air bags

   Air bags deploying without a crash

   • 16 complaints (14%)
   • median 90,000 mi at 15.3 yrs old (10 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2000–2021

   Owners report side curtain, door or frontal air bags deploying without a collision, sometimes after hitting a pothole or while driving at speed. Complaints describe damage to the headliner and trim, and in some cases the engine stalling at the same time. According to the complaints, some cars were not covered by the side air bag recall campaign because the VIN was not included. Reported between roughly 50,000 and 182,000 miles, several times after a pothole or rough road.

   Recall 02V223000

   What to check: Ask whether the car has had any air bag deployments or module replacements, and check for mismatched or replaced interior trim and headliner. Confirm recall status by VIN with a dealer.

   “I was driving the vehicle in the early morning still dark on a state road and raining very hard could not see out the windshield. I believe I hit a pot hole. That's when the side curtain deployed on the right side causing damage to the headliner and a pillar post. Unknown why it went off. I know there's a recall for the front airbags and some forums stated this has happened to them as well. I inspected the vehicle and I could not see any other damage to the vehicle.”

   NHTSA complaint #11403437, filed 2021-03, 96,000 miles

   “2000, 328I Bmw. My driverside airbags deployed with no impact or accident. Bmw has offered to settle if I sign a broad release saying I can't talk to anyone in the media, etc. They insist I hit something in the road which I did not. My son was in the passenger seat next to me when this occurred. I thought that we had been shot, my arm hurt so bad. But my son screamed, mom it is your airbag . We called Bmw roadside assistance and towed it to the Bmw dealership. I thought that we did everything right. But, Bmw is calling me a liar. …”

Buying note. A pre-purchase inspection focused on the rear subframe mounting points and a cold test of reverse gear covers the two most frequently reported problems on this model year. Ask for service records and confirm by VIN that any open air bag recalls have been completed.
