Versions

NHTSA's VIN data lists no trims for the 2024 EQB, so these are the versions EPA tested, by its names. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.

Problems owners report

Owners have filed 12 complaints with NHTSA about the 2024 EQB. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

What the columns count

Complaints by model year

Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.

Recalls

NHTSA lists 2 recall campaigns for the 2024 EQB over its history, 1 replaced by a later one. A replaced campaign is listed at the end as history, not as a separate repair. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Repaired under campaign 25V050000? NHTSA's record says it still needs the newer remedy of campaign 26V073000. A repair under the earlier campaign doesn't complete the later one: check the VIN on NHTSA's recall lookup.
