severe NHTSA 17V507000 August 16, 2017

BMW of North America, LLC (BMW) is recalling certain 2018 430i, 430i xDrive, 440i, 440i xDrive, and M4 convertible vehicles

If the vehicle has an incompatible vehicle-sensitive locking mechanism, the seat belt may not restrain the seat occupant in the event of a crash, increasing the risk of injury.

Fix: BMW will notify owners, and dealers will inspect and, if necessary replace, the front seat belt assemblies, free of charge. The recall began October 13, 2017. Owners may contact BMW customer service at 1-800-525-7417.

Common questions

Is the 2018 BMW M4 reliable?

Limited NHTSA data. Only 5 owner complaints have been filed for the 2018 BMW M4, which is not enough for a meaningful reliability score. Active recalls (if any) are listed on this page and remain authoritative — those are verified defects regardless of complaint volume. For a confident reliability read we look for at least 10 owner complaints in the federal database.

Should you avoid the 2018 BMW M4?

Only 5 NHTSA complaints on file — too few for a confident call. The 1 active recall above remain authoritative; read those first. We don't issue a buy/avoid verdict on the 2018 BMW M4 without a meaningful complaint sample — doing so off a handful of filings would be guesswork.

What should I check before buying a used 2018 BMW M4?

There isn't enough NHTSA complaint data on the 2018 BMW M4 to flag a standout failure pattern. Run the VIN for open recalls — those are free to fix regardless of warranty — get a standard pre-purchase inspection, and ask the seller for service records.

Is the 2018 BMW M4 a good used car to buy?

Hard to say from federal data alone — only 5 owner complaints have been filed. Lean on the recall list above, a pre-purchase inspection, and a vehicle-history report on the specific VIN. Our data tells you what the model is known for; a history report tells you what that exact car has been through.

What's the most common problem on the 2018 BMW M4?

No problem area has crossed our reporting threshold yet, which is a good sign for this vehicle.

What's the most expensive thing that goes wrong?

Major repair items haven't been flagged often enough on this vehicle to single one out.

How do I check if my BMW M4 has open recalls?

Paste your VIN into the decoder at the top of this page. We pull live from NHTSA, so you'll see exactly which campaigns apply to your vehicle and whether the dealer has logged the fix. Recall repairs are always free regardless of mileage or warranty status.

Is an extended warranty worth it on a 2018 BMW M4?

Hard to say from NHTSA data alone with only 5 complaints on file. A quality service contract runs $1,800–3,500 over 3 years. The decision comes down to your specific situation: vehicle cost, miles on it, how long you plan to keep it, and whether you can absorb a $3K–$8K repair without straining cashflow. With limited public data on this vehicle, lean on the recall list above and check owner forums before committing.
