1 Warnings problem of the 2020 BMW 330

Failure Date: 09/26/2026

Several months ago, my digital cluster on my 2020 330i blacked out briefly and came back on. The other day, after temporarily disconnecting the batter and correctly reconnecting, the digital cluster and driver assist items all failed. Because of this failure, I no longer have access to my speedometer, engine temperature, or engine lights in the event that something needs immediate attention. Not having the speedometer requires me to check my speed using a gps device would causes me to divert my attention from the road which is a hazard to pedestrians and drivers alike. I also do not have the driver assist items which can result in an accident which would injure both myself and other drivers. The cluster has not returned to being functional, which was confirmed by the dealership after completing a full ista troubleshooting tree. There were no warnings that this would happen, it just immediately died after a power cycle of the battery.

3 Warnings problem of the 2020 BMW 330

Failure Date: 12/04/2025

Within days of purchasing the vehicle, multiple warning lights and safety-related alerts appeared, including repeated check engine warnings, an alert stating “driver assistance support reduced,” and a wrench indicator referencing an auto lighting and wiping system malfunction. While driving, the vehicle felt unstable and would sway side to side, making it difficult to maintain confident control. The vehicle was brought in for service shortly after purchase due to these concerns and was removed from my possession because of the seriousness of the issues. During the service process, I was informed that the vehicle had previously been involved in an accident and that a critical structural safety component (the front crash bar) was damaged. This damage had not been disclosed prior to purchase. The crash bar is a key part of the vehicle’s body structure designed to absorb impact and protect occupants in a collision. Driving a vehicle with damage to this component posed a potential safety risk. The combination of structural damage, reduced driver assistance alerts, visibility system warnings, and unstable handling raised concerns about crash protection, vehicle control, and overall safety. The issues were identified by the selling dealer during inspection after the vehicle was returned for service and are available for further inspection if requested.

5 Warnings problem of the 2021 BMW 330

Failure Date: 05/03/2024

This BMW vehicle's odometer readings are inconsistent and inaccurate resulting in overage of mileage for lessee. This cars BMW tires were not verifiable to be from BMW and tires subsequently failed within 15,000 miles. No entity at BMW, not the dealership, not the sales, not BMW financial services or BMW of north America llc could provide any information regarding the original tires or provide any warranty information regarding the tires - this impact mileage efficiency, miles per gallon and is a way to game the systems. BMW front sensors on act erratically sometimes working and sometimes going off without anything present, during rain/snow sensors would constantly go off for no reason. Issues have been raised through certified mail to BMW and all have been ignored. There is no accountability regarding the tires with no warranty that fail, inaccurate odometer readings, car sensors and we request an investigation into these three matters.
