Is the BMW 4-Series more reliable than the Mercedes-Benz E-Class?

No, the two are effectively tied. Both have a good standing and nearly the same recall count. The 4-Series gets more owner complaints per car sold, 15.8 per 10,000 against 7 for the E-Class, but the E-Class has its own severe failures, like dead 48-volt batteries.

Which has more recalls, the 4-Series or the E-Class?

They are almost level. Federal recall records show 182 recalls across 9 model years for the 4-Series and 184 across 8 model years for the E-Class. That gap is too small to separate them, so look at the specific recalls on the exact car you are considering.

Which car has more crash-linked complaints?

The 4-Series. Its air bag complaints include 12 crash-linked reports, and its electrical and brake areas have 8 each. The E-Class has 3 crash-linked electrical complaints and 2 in steering. Its engine, power train and seat belt areas show none.

What goes wrong with the Mercedes-Benz E-Class?

The most common reports involve the electrical system. The 48-volt battery can fail early and leave the car unable to start, sometimes before 1,000 miles. Owners also report cylinder misfires with limp mode, front seat belts that do not retract, and two cases of transmission failure at low mileage.

Mercedes-Benz E-Class

The BMW 4-Series and Mercedes-Benz E-Class are effectively tied on reliability. Recalls are nearly equal, at 182 and 184. The split is in complaints: the 4-Series has more per car sold, with crash-linked air bag, brake and electrical reports, while the E-Class has fewer.

How Do the BMW 4 Series and Mercedes-Benz E-Class Generations Compare?

Shoppers looking at 2018 to 2020 are buying the first-generation 4-Series (F32/F33/F36), which ran in the US from 2014 to 2020. The second generation (G22/G23/G26) began in 2020 and the data lists it through 2023. Model year 2020 spans both designs and is one of the weakest years. For the E-Class, the fifth generation (W213) ran from 2016 to 2023, with a facelift in 2020. The sixth generation (W214) began in 2023. Used buyers of 2018 and 2019 are therefore getting the pre-facelift W213, and both of those years rank among its weakest.

Verdict

The BMW 4 Series and Mercedes-Benz E-Class are evenly matched with a reliability score of 60/100.

Neither car pulls ahead. Both land in good standing, and federal recall records are almost level, at 182 recalls for the 4-Series and 184 for the E-Class. The 4-Series draws more than twice the owner complaints per car sold. Its complaints also touch more safety systems, with air bags, brakes and electrical faults all tied to crashes. The E-Class has fewer complaints but a few severe single failures, like early transmission loss and dead 48-volt batteries. Those offsetting patterns keep the call at effectively tied, so the choice should come down to which risks you can live with.

What Are the Common Problems With the BMW 4 Series and Mercedes-Benz E-Class?

Safety systems dominate the 4-Series complaints. Air bag reports center on "Air Bag Off" warnings, sometimes traced to the seat occupancy sensor, and 12 are crash-linked. Electrical reports include total shutoff while moving, and brake reports describe a sinking pedal. Coolant leaks from water pump seals and plastic hoses also appear. The E-Class profile is lighter but odd. Its 48-volt battery can die before 1,000 miles and strand the car. Misfires put it in limp mode, and two reports describe transmission failure at low mileage. Its crash-linked areas are only electrical and steering. Engine, power train and seat belt complaints have none.

Best years to cross-shop: The 2024 BMW 4 Series scored 66/100 and the 2024 Mercedes-Benz E-Class scored 63/100 — the strongest shared model years that have been on the road for at least two years, where available.

Who Should Buy the BMW 4 Series vs the Mercedes-Benz E-Class?

Pick the E-Class if you want fewer complaints overall and a smaller set of crash-linked problem areas. It suits a shopper who can tolerate an early battery or misfire visit, and who will check that the 48-volt battery has been replaced and the steering recall repair is done. Avoid 2018 and 2019, its weakest years. Pick the 4-Series if you want a coupe and are willing to check the safety systems closely. Make sure no "Air Bag Off" or passenger restraint warning shows, ask for coolant leak repairs on the record, and confirm any brake recall work is finished. Avoid 2018 and 2020, its weakest years. Both cars list 2024 among their strongest years, but newer cars have had less time to collect complaints, so a clean record there is not proof of better quality. A documented service history matters more than the badge.
