2018 BMW 5 Series Complaints

ELECTRICAL SYSTEM,ENGINE — Filed 03/02/2026

My 2018 BMW 530e suddenly shut down while I was driving. I charged it overnight, but the next day it showed a check‑engine light and a drivetrain failure warning. I tried driving it again, and it drove for some distance and shutdown after few minutes. Luckily, i was able to park the car on the side of the road. I brought(towed) it to a mechanic, and he told me the issue was a CCU failure, which would cost about 12,000 to fix. I believe this should be covered by the manufacturer because this isn’t a normal wear‑and‑tear problem, and I can’t absorb such a high repair cost."

Passenger seat occupancy sensor faulty causing restraint system malfunction and seat belt warning

I got a "Drivetrain malfunction" error on my 2018 530e bmw, which is a hybrid plug-in model. I sent the car to the local dealer. They did all the diagnosis and concluded the high voltage battery needed to be replaced. However, they told me that the warranty (80K/8 years) will not cover it although my card is still in the warranty period. The dealer said that the BMW North America made the decision and there was nothing they could do. Without replacing the battery, the car could fail on the highway, which could be a huge safety concern. I called BMW North America and talked to the warranty department, the guy sounded stoned/disillusioned with his job/just woke up and said there’s nothing he can do and the dealership already talked to the warranty department/somebody the public doesn’t have access to and the dealership goes with whatever that department tells them.

I was driving home after picking my son up from school and out of no where the vehicle temperature was in the red and a message popped up stating that vehicle coolant needed to be replenished but that continued driving of the vehicle was ok. It was not ok at all! The car started smoking and we were left stranded on the side of the road. I’ve read numerous blogs showing that the same thing has happened to other people and that there have even been recalls on other bmw’s in regards to the engine coolant system.

SEAT BELTS — Filed 04/08/2025

The seatbelt/passenger seat fails to recognize a passenger is occupying the seat and turns off the airbag. This issue has been reported many times to BMW and on vehicle forums. This is an expensive fix ($2800) that should be issued a recall by the manufacture and not passed onto the owner of the car.
