The 2018 BMW M4 is hailed as one of the best luxury cars on the market. Even the automaker says the new lineup provides “iconic performance.” Research shows that actual customers feel quite differently. In fact, the electrical glitches, decreased structural integrity, defective powertrain and malfunctioning brakes leave customers wishing for a different vehicle.

NHTSA Complaints for the 2018 BMW M4

Problems with the Electrical System
When it comes to having a luxury car, it’s expected that the electrical system would work seamlessly, without any hiccups, but that’s not the case.
Within this extensive complaint from an Edmunds user, you can see several electrical concerns. “Purchased new, the car does not handle well. The steering resembles a generic lawnmower. The vehicle is not fast and the prepaid maintenance services do not include fluid flushes or alignment. The alarm on the vehicle does not work. The blind spot sensors on the side mirrors also do not function reliably. The car cannot take wide turns without the back tires sliding out of control.”
The automaker has a long list of technical bulletins related to the electrical system. Another instance, Service Bulletin #B840719, illustrates how the Bluetooth connection gets lost in the middle of phone calls. The hands-free system will revert to the phone, leaving drivers in a precarious situation. If “iconic performance” means going old school with the technology, then this model is a winner.
Problems with the Powertrain
As part of the powertrain, the transmission is a major component that must operate correctly for smooth-shifting driving, but it’s not the only part of the system that can fail.
Just look at this comment left on the Bimmerpost Forum. “Drivetrain Malfunction. Drive Moderately. Maximum Drivetrain Output Not Available. It’s a 2018 m4 convertible. It just came up yesterday. Car only has 3400 miles on it. It came on as soon as I slowed down for traffic, I didn’t have to turn the car off or anything went to neutral and then back to gear and the message went away. Took a picture. It’s at the dealer now.”
Sadly, these aren’t the only powertrain-related complaints. Even the automaker acknowledges problems with Service Bulletin #B310318 that discusses a cracking noise coming from the vehicle during parking and braking. It appears that some of the connections were left loose and need to be tightened or lubricated. How does a luxury car costing this much money leave the factory with loose connections? The engineers might have been too busy coming up with that innovative tagline that there wasn’t time to complete the build.
Problems with the Vehicle Structure
Not everyone is thrilled with the quality of manufacturing either. This luxury car leaves a lot to be desired.
Here is one Cars.com review. “Very expensive for quality.Definitely not worth the money.Service at dealer less than acceptable. Wind noise from windows is ‘how this vehicle is made.’ Every time it was the same excuse….. over it. Wish I never bought this BMW. Save your money & try Lexus or Jaguar.”
Even the seat belts weren’t produced properly. Recall Number 17V507000 talks about how the Emergency Locking Retractors (ELR) in the front seat belt assemblies might not have the proper locking mechanism, which leaves the occupants unrestrained during an accident. This vehicle might provide exceptional performance, but there’s nothing stopping the occupants when a crash occurs. Guess that’s what makes it “iconic.”
Problems with the Brakes
With all the other problems this car has, it would be helpful to have a quality set of brakes to slow the vehicle down, but that’s not the case either.
Just look at this comment from the Bimmerpost Forum. “The brakes feel like they are rough like feel like they are grinding but they don’t grind, just feel it through the pedal, is that normal? It only feels like that after a couple of soft presses on the brakes. Is it me or the m4 breaks are rough to begin with?”
What’s interesting about BMW is that the company doesn’t try to hide anything. In fact, the automaker is forthcoming about problems many people might never know about. Service Bulletin #B340615 talks about how pebbles, foreign materials and road matter can easily get caught between the brake protection plate and the disc, leading to a grinding noise. So, while driving a high-end luxury performance car, owners also get to experience grinding brakes, seat belts that don’t work, a faulty powertrain and dropped calls from the Bluetooth. Sounds like it’s time to jump ship and look at one of the other luxury automakers for a car.
