2018 BMW 430i Problems and Top Complaints – Is Your Car A Lemon?

Electrical system, poor seats and vehicle structure issues among the top complaints received by the NHTSA from vehicle owners

Among the lineup of luxury cars, the 2018 BMW 430i catches a lot of attention. The unique styling is dramatic and it appears to be a high-powered model that draws drivers in. Even the automaker claims that the new models are “styled to thrill,” however the design might be all that makes this vehicle unique. It suffers from electrical malfunctions, unsafe seats and a poorly-built structure.

Problems with the Electrical System

Modern luxury cars are equipped with high-tech features that make driving easier than ever. When these systems begin to fail, the drive can be quite disastrous.

Here is what one Edmunds user said about electrical issues. “Well what a terrible experience!  This cars A/C hasn’t worked in 3 months. The dealer said it could have been possibly caused by a rock so the warranty won’t cover it. Also BMW changed the A/C system in 2018 so it is very difficult to find anyone who can charge the A/C! The water pump had to be replaced already and both tail lights now have to be replaced for condensation.”

The problem highlighted above is related to the electrical components of the air conditioning, but everything runs on the electrical system of today’s vehicles. When there is a glitch, owners can experience significant safety concerns as well as nuisances. One such nuisance that quickly becomes a safety issue is illustrated in Service Bulletin #B840719. BMW acknowledges that the Bluetooth connection can be lost during a phone call. Instead of projecting the call across the system, it will revert back to the phone. As a driver attempts to figure out where the call went, an accident could occur. It seems the 430i has some wires crossed that makes this luxury car a lemon.

Problems with the Seats

Most people don’t give much thought to the seating until a long drive occurs. While the seating is important for comfort, there’s also a safety factor.

Look at the danger this NHTSA complaint points out. “The contact owns a 2018 BMW 430i. The contact stated that while reversing into a parking space, the contact’s foot slipped off the brake and onto the accelerator pedal. The vehicle accelerated in reverse and crashed into a telephone pole. The front driver’s seat collapsed out of place and fell backwards. No airbags deployed. The contact sustained neck injuries and the passenger sustained none. The contact was taken to the hospital where she stayed overnight and they confirmed the contact sustained ligament damage. A police report was made. The vehicle was towed by the police to a collision center. The dealer and the manufacturer were not made aware of the failure. The failure mileage was approximately 24,000.”

Sadly, this isn’t the only safety-related issue to be concerned about. Recall Number 17V507000 points out that the Emergency Locking Retractors (ELR) on the front seat assemblies might not have the compatible locking mechanism housings included. This defect prevents the seat belt from restraining occupants during a crash. Not only can the seat collapse on an occupant, but the seat belt could fail as well. This is a “thrill” that most owners aren’t signing up for when they purchase the 430i.

Problems with the Vehicle Structure

It’s become evident that BMW engineers haven’t done a good job of constructing this luxury model, but if further proof is needed, just take a look at the defective structure.

An NHTSA statement says “I pulled in my driveway and turned off the engine. I used the internal button to open the trunk then opened my door and got out of the car. The key was in my purse on my shoulder. I was reaching into the trunk to gather my belonging, and the car made a steady alarm sound I have never heard before and the trunk closed on my arm. I was able to pull my arm out while it was pinned in the trunk, but I have two painful subdermal hematomas on my right arm.”

BMW acknowledges that there is an issue with the tailgate. Service Bulletin #B513016 shows that the tailgate can unintentionally open, even if the vehicle is locked. Among other structural issues, we see Service Bulletin #B513316, which states that owners experience sloshing noises and water located in the rear passenger compartment. Does this sound like problems that a “styled to thrill” vehicle should be producing? Unless the thrill means putting life and limb at risk, then it’s best to avoid this poorly constructed luxury car. Even the budget-friendly cheap cars don’t suffer from destructive malfunctions such as these.
