Kestrel Take

The first year of the W212 sedan and wagon, and the record points at three things rather than one: a Takata inflator campaign that dozens of owners filed about because parts took years to arrive, a rear subframe that corrodes where the suspension arms bolt into it, and a fuel sending unit that weeps at the back of the car. All three are checkable in an afternoon — a VIN lookup, twenty minutes on a lift, and a sniff around the rear seat after a full tank. Buy one with those three answered and you are getting a lot of car for the money. Buy one with them unanswered and the first repair can cost more than the car.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 257 owner complaints for the 2010 Mercedes-Benz E-Class, and 4 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 39% of them are about one thing — airbags. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

4 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2010 Mercedes-Benz E-Class

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Takata airbag inflator — the largest cluster in the record by a wide marginHigh — wallet impact

A hundred of the 257 complaints on this year are airbags, and reading them, almost all are owners saying they got a recall letter for the Takata inflator and the dealer had no part for months or years. A degraded inflator can rupture and throw metal into the cabin. The replacement is free under the manufacturer campaign. Put the VIN into NHTSA's recall lookup before you hand over money: it will tell you in ten seconds whether the work was ever done on this exact car.

Repair cost: Not yet priced — a safety matter first, a repair bill second

Rear subframe rusts through where the suspension arms bolt inHigh — wallet impact

Owners describe a technician finding the rear subframe rusted out with the lateral strut arm starting to break away, on cars with no other visible rust anywhere. One reports the rear wheels feeling like they were steering themselves under braking. This is structural: if it lets go, the rear suspension geometry goes with it. Get the car on a lift and look at the seams and the boxed sections of the rear crossmember, especially on any car that has lived where roads are salted.

Repair cost (estimate): $2,500–$5,500 — around 69% of what this car is typically worth

Airmatic air suspension leaks down and the car sits on its bump stops overnightMedium

Several owners in the same suspension cluster describe the car dropping to the floor overnight — sometimes the front, sometimes the rear, sometimes all four corners — and a CAR TOO LOW warning on the dash. It is a leaking air strut or a tired compressor. Only some 2010s have Airmatic, so first establish which suspension the car has, then park it level, note the gap between tyre and arch at each corner, and come back in the morning.

Repair cost (estimate): $900–$2,200 per air strut; $600–$1,100 for the compressor — about 28% of what this car is typically worth

Fuel sending unit leaks and the car smells of petrol after a fill-upHigh — wallet impact

The fuel cluster is almost entirely one complaint written twenty-four different ways: a strong gasoline smell at the rear of the car, worst right after filling the tank, strong enough that owners stopped parking in the garage. One lifted the rear seat and found a puddle around the sending unit. Fuel pooling near a hot exhaust is not something to negotiate about. Fill the tank during the test drive, then stand at the left rear wheel and the boot lid and use your nose.

Repair cost (estimate): $400–$1,400 per sending unit; $1,200–$2,400 if both sides need doing — about 30% of what this car is typically worth

Electronic steering lock jams and the car will not crankMedium

The electrical cluster includes reports of the steering wheel staying locked with the car refusing to do anything at all. On these Mercedes it is usually the electronic steering lock module in the column, and when it fails the car is immobile where it stands — a tow, not a roadside fix. On the test drive, shut the car fully down, remove the key, then restart it two or three times and watch that the wheel frees every time.

Repair cost (estimate): $600–$1,600

✗One corner of the car sitting visibly lower in the morning than it did overnight
✗Orange scaling or flaking metal on the rear subframe seams when you look underneath
✗A CAR TOO LOW or Airmatic malfunction message on the dash
✗The key turning but the steering wheel staying locked and the starter silent
