Who Should Buy BMW vs Mercedes-Benz?
For a sedan, lean BMW. Target the I4, 3-Series or 5-Series, all in good standing. The I4 is electric, and 2024 is the year the data points to. Watch for propulsion cutting out with a drivetrain malfunction message. Among Mercedes-Benz sedans, only the E-Class stands good. Skip the CLA, and the 2022 above all, since owners report transmissions dropping into Neutral while driving.
For an SUV, lean Mercedes-Benz. The GLB, GLC and GLE all stand good. Buy a 2022 or 2023 GLB, skip the 2020, and read the service history for reports of cylinder head and valve failures. On the BMW side, the X1, X3 and X7 are good, but the X5 and IX are only mixed. If you want the IX anyway, choose the 2024, which had fewer recalls than the 2022 or 2023.
The Bottom Line: BMW or Mercedes-Benz?
Choose BMW for the more reliable bet, especially in a sedan. Choose Mercedes-Benz if you want an SUV and lower running costs. The strongest single model across both lineups is the BMW I4, and the 2024 is the year to target. Mercedes-Benz averages $179 less a year in estimated repair cost, about $895 over five years. Check recall history on any car before you buy.
