A left front seat belt was built wrong in four new Mercedes-Benz CLA 220 sedans

The recall concerns a left front seat belt, the one worn by the driver. Mercedes-Benz USA reported the problem in a Part 573 safety recall filing dated October 2, 2026. The filing states that “a component of the left front seat belt may be installed incorrectly.” No other seat position and no other model appears in the vehicle list, which reads simply “2027 CLA 220 vehicles.”

What the filing says is wrong with the belt

The defect summary is short, and it names a single part of a single belt. A component of the left front seat belt may have been put in wrongly during assembly, which is a manufacturing error rather than a design problem shared by every CLA. The filing does not describe which component is involved in the text available for this article, and no cause is stated beyond the installation itself. The narrowness matters for how the recall should be read. A defect confined to one component in one seat position, in four cars, points to a problem at the point of assembly, not to a flaw that every buyer of the model should expect.

Why a misplaced component is a restraint problem

The consequence listed in the record is direct. In the filing’s words, “a seat belt with an incorrectly installed component may fail to properly restrain occupants, increasing the risk of injury during a crash.” The wording is conditional: the belt may fail, and the filing does not report any crash or injury linked to these four sedans. Four 2027 Mercedes-Benz CLA 220 sedans are covered by NHTSA recall 26V636000, and the National Highway Traffic Safety Administration’s recall records list the potentially affected count as exactly that: “Potentially affected: 4.”

The conditional wording is standard for this kind of report, but the stake is plain. NHTSA’s own seat belt guidance says front seat belts reduce the risk of fatal injury by 45 percent in passenger cars and cut moderate to critical injury by 50 percent. It also credits belts with saving an estimated 14,955 lives in 2017. Those figures describe belts that work as designed. A belt with a component in the wrong place may not deliver that protection, and the driver’s seat is where the person with the most control over the car sits.

Four vehicles is a very small recall by the standards of the industry, where campaigns often run to tens of thousands of cars. The size changes the logistics, not the seriousness of the defect for the person sitting in one of those four seats.

What owners can expect and when

The filing gives a notification date of November 27, 2026. That is when owner letters are due to go out for 26V636000, which is roughly eight weeks after the October 2 filing. NHTSA says on its recalls page that manufacturers must send notice by mail within 60 days of notifying the agency of a recall decision, and that owners should contact a local dealership to have the recalled part fixed “for free.” The same page explains that a vehicle identification number lookup shows whether a car has an open recall, though it warns that some newly announced recalls may not yet appear because their VINs have not been identified. In its words, “VINs are added continuously so please check regularly.” For a recall this small, the practical path is a dealership visit once a letter arrives or a VIN check on NHTSA’s site before then.

The filing text read for this article does not include the remedy, so the repair itself is not described here. Mercedes-Benz USA’s notification letters will carry that detail, and NHTSA typically posts the manufacturer’s notice alongside the recall once it is available.

Reading the NHTSA dataset behind the recall

The recall appears in a public dataset that NHTSA publishes through the Department of Transportation’s open data portal. The dataset itself can be queried by anyone, and sorting by the date a report was received, as in this five-record query, surfaces the newest filings first. Each record carries the fields quoted above: the count of potentially affected vehicles, the defect summary, the consequence, the model list and the notification date.

The dataset structure explains why a four-car recall can be reported at all. Every Part 573 filing becomes a row, whatever its size, and each row can be checked against a recall number. Here the number is 26V636000, the manufacturer is Mercedes-Benz USA, and the affected population is four 2027 CLA 220 sedans. For anyone shopping for a new CLA, the entry is a reminder to run a VIN check before signing. For the owners of the four cars, the date to watch is November 27, when the letters are due. Until then, the only fact the record establishes is that one belt in each of four sedans was built in a way that could leave a driver less protected than the design intends.
