Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2022 BMW M340i sits at the tail end of a clear downward trend in reported issues for this generation. After a spike to 49 complaints and 10 recalls in 2020, the numbers fell sharply to 11 complaints and 6 recalls in 2021, then dropped further to just 6 complaints and a single recall for 2022. Technical Service Bulletins (TSBs) followed the same arc, peaking at 251 in 2020 before declining to 183 in 2021 and 58 in 2022, indicating that many early production concerns were resolved. The 2022 model’s top complaint areas are each represented by only one report, with no single system dominating, and there are zero crash or fire complaints. This year represents the most mature and trouble-free point in the generation’s lifecycle, making it a particularly sound choice for a used purchase.
