2018 BMW 530E

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."

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.

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.

i have read all the forums and there are many complaints on this same safety issue and why hasn't a recall been issued? Passenger restraint system light stay on !

1. Telematics Control Unit (TCU) Internal Emergency (Backup) Battery malfunction. It is available for inspection. It puts passengers at risk because passenger are not able to make emergency calls. Its warning message on dashboard blocks display of car mileage. BMW issued letter in December 2024 admitting to the defect. Our car 2018 BMW has been experiencing the malfunction since 2023.7 or earlier as evidenced by dealer service record. But BMW only in Dec 2024 started offering 6 year extended warranty from car delivery. BMW NA and dealership denied servicing the defect in our car when we requested in Jan 2025. We demand BMW to recall all cars having the defects or cover all extended warranty for 15 years. 2. GPS malfunction. GPS registers the wrong position of the car. It puts passengers at risk by directing them to wrong destinations such as open waters. Issue occurred since Dec. 2024. No warning sign.

The Passenger Restraint System Malfunction warning light comes on randomly. Also the passenger side seat belt light comes on even if I put my wallet or something very light on the seat. I previously replaced the driver side seat sensor because the restraint system error was coming on. It seems odd that this critical component would fail in both seats by year six.

The occupant sensor in the driver seat has failed, triggering an airbag warning. This car is only 6 years old, and the cost of the part/labor to repair it is $2500.

Passenger Restraint System Malfunction keeps coming on. I have not done any modifications to the car, it comes on during the morning when maybe the weather is a little damp. Has happened twice in a month.

It appears that the dealer has disabled my passenger side air bag system. The car is available for inspection. The safety of any front passenger is at risk as the system has been disabled by the dealer after a 'vehicle check' that occurred during routine maintenance. The problem (airbag system disabled) has been confirmed by the same BMW dealer that performed the service. The vehicle has not had additional inspections. Prior to this problem, an alert/message would indicate the passenger would need to buckle up. Never was a passenger in the seat, I would move the groceries, backpack, water bottle, etc to the floor and message would dismiss itself. This message to buckle up has been appearing since the car was purchased as a certified BMW from a BMW dealer. Recently, I took my car into the BMW dealer that I typically go for scheduled, routine maintenance. The maintenance consisted of an oil change, oil filter change, air filter change, and vehicle check. When I started the car after picking it up, a chime sounded and a warning message was displayed that says "Passenger restraint system malfunction: Contact BMW Carefully drive to the closest service center. Passenger restraint system is limited. Increased risk of injury in case of a collision. Continue wearing safety belt." Additionally, a red air bad light is displayed on the dash board instrument cluster. Every time the car is started the chime sounds and these message is displayed. Dealer is requesting 2,000-2,500 to replace a part - meanwhile system was dealer disabled. Please note this issue has occurred in the past with BMW SRS systems, and a recall resolved the issue.

I continually get the message 'passenger restraint system malfunction' Was meant to be repaired under warranty in 2022, it came back, but problem persisted intermittently since.

Digital display cluster suddenly started flickering and had a shifting image moving incorrectly to the left. It made reading the electronic speedometer and other gauges impossible and highly unsafe while driving on highway. There was no way to safely determine speed or vehicle. The display did not recover after parking the car and restarting engine.

The passenger seat is a mess. There are two issues that repeatedly happen on this car. One - there is false passenger seatbelt warning and two their is a passenger restraint system malfunction message. I took this to the BMW dealership and they said it requires a sensor mat replacement that costs over $2000. I looked it up online and found many people have had the exact same issue with this car.

I took my car to pacific bmw in Glendale California on July 21 2023. It was getting a battery replacement under warranty. I recieved my car back November 16 2023. After 4 months of waiting and being Discriminated against, my car only got 3 out of 6 battery modules replaced. It's a safety hazard to mix new and used lithium batteries. Warranty covered me for all 6 modules to be changed but the dealership deliberately only fixed 3. After being advised to change them all.also they charged me for parts covered under warranty. I took my car in because I would get 4-6 miles on a full charge. Pacific gave it back to me with 9 miles on a full charge. It should be at least 18. I do not feel safe in my own car. Yes I have attached proof.

BMW has had known issues with its passenger seat safety sensors failing. These are expensive repairs exceeding $2,000+ and happen frequently with the 2018 - 2020 BMW 5 Series. My 2018 BMW 530e has had this sensor fail with regular usage. There hasn't been an abnormal exposure to moisture (I live in Utah, a very dry climate) and so the vulnerability of this technology and the cost associated with it's upkeep and it's necessity for basic safety, means BMW should own up to ensuring that this has better and more reliable craftsmanship.

I get the message “Passanger Restraint System Failure” at random times.

KLE MODULE FAILURE - Causing short on EV Hard Wires Wall Charger. Module Burned out on vehicle, which could cause fire and electrical problems. This failure also causes problems with emissions issues as this is a Hybrid Vehicle. BMW has has several issues with this and advising that it is not a covered part in the 2018 module, but has been covered and repaired in 2019 + Vehicles.

Passenger seat belt warning light activates even though there is no one or anything in the passenger seat.

MESSAGE OCCURS WITHIN A COUPLE MINUTES OR DRIVING AND WILL SELF-CLEAR AFTER ABOUT A MINUTE. PROBLEM OCCURS SEEMINGLY RANDOMLY AND INTERMITTENTLY.

THIS IS THE SECOND OCCURRENCE OF THE RIGHT FRONT DOOR OPENING WHILE MY CAR WAS IN MOTION. DURING THIS OCCURRENCE, WITHIN A COUPLE MINUTES OF STARTING THE CAR AND DRIVING, FIRST THROUGH A PARKING LOT, AND THEN TURNING RIGHT AND ACCELERATING ON A STREET, AT APPROXIMATELY 15-20 MPH THE RIGHT FRONT DOOR OPENED BY ITSELF. NO ALARMS, TONES OR WARNING LIGHTS WERE PRESENT UNTIL THE DOOR OPENED ON ITS OWN.

RIGHT FRONT DOOR OPENED BY ITSELF WHILE CAR WAS IN MOTION. WHEN DOOR OPENED BY ITSELF, A LIGHT ON THE INSTRUMENT PANEL ILLUMINATED AND A WARNING TONE SOUNDED. PULLED THE CAR OVER TO THE SIDE OF THE ROAD AND SLAMMED DOOR SHUT.

AFTER HAVING MY BMW 530E RUN THROUGH A HAND AND SEMIAUTOMATED CAR WASH, THE CAR WAS DRIED AND DETAILED. WHEN I GOT IN THE CAR AND BEFORE TURNING THE 530E ON, THE IDRIVE SCREEN WAS DISPLAYING A WARNING MESSAGE INDICATING THAT "BATTERY CANNOT BE RECHARGED" AND TO "STOP CAREFULLY: POWER SUPPLY." THE UNDERCARRIAGE WASH WAS NOT DONE ON THIS TRIP TO THE CAR WASH AS IT IS AN ADDED FEATURE. CONTACTED BMW THROUGH THE IDRIVE SYSTEM AND SPOKE TO A MASTER TECHNICIAN WHO ADVISED TO NEVER DO A AN UNDERCARRIAGE WASH. HE ALSO ADVISED TO TURN OFF THE CAR FOR 10 MINUTES. AFTER 10 MINUTES THE MASTER TECH CALLED BACK AND I RESTARTED THE CAR AND ALL WARNINGS WERE GONE AND IDRIVE VEHICLE STATUS WAS "ALL SYSTEMS OK." MY 530E DROVE HOME 10 MILES WITHOUT ANY FURTHER ISSUES.
