"Wood trim came unglued"

Anonymous, SC (2012 Mercedes-Benz E-Class E350 3.5-L V6)

"Front passenger airbag sensor visual alarm is always on. Drivers airbag sensor malfunctioned, and was repaired under a recall notice. MERCEDES-BENZ refuses to cover the passenger side malfunction. Since this is such a serious safety issue and clearly a malfunction, I believe MERCEDES-BENZ should pay for this repair. Drivers seat belt no longer retracts, and MERCEDES-BENZ also refuses to pay for this very critical safety issue."

Anonymous A., AZ (2012 Mercedes-Benz E-Class E350 3.5-L V6)

"Starter motor failed."

Anonymous, TX (2012 Mercedes-Benz E-Class E63 AMG 5.5-L V8 turbo)

What Owners Say

Bushings

"Wore out after 12 years."

Anonymous A., NV (2012 Mercedes-Benz E-Class E550 5.5-L V8 turbo)

Electronic or air suspension

"My sport wagon has only been serviced by dealer. Over time, the vehicle stance became lower. Mentioned to dealer, and was told that this is normal because of sport and AMG packages. Then the wagon progressively displayed more messages about waiting for the vehicle to be raised prior to driving. Again, contacted dealer. After all the back-and-forth, by the time of the appointment when the suspension would be finally serviced, the air suspension failed on the interstate about 2 miles from the dealership. The vehicle chassis was nearly touching the ground. The delayed service not only made the repair more expensive (dealer even billed above MSRP for all parts), but also a dealer ignored safety issue."

Other steering/suspension problem

"During routine maintanence the MB dealer advised that the rear suspension subtructure was corroded. MB then sent us a letter advising they were replacing this unit free of charge as a safety advisory. They then replaced the entire section including new springs. It was a full days work and parts by the MB service department. The car ran fine before the problem was noted and it continues to run fine after the repair."

Anonymous A., RI (2012 Mercedes-Benz E-Class E350 BlueTec 3.5-L V6)

Climate System

AC compressor, blower (fan) motor, condenser, evaporator, heater system, automatic climate system, electrical failure, refrigerant leakage.

What Owners Say

Blower (fan) motor

"HVAC issues are known and discussed in previous service campaigns, from which I have yet to receive benefit. Latest issue is that whenever the HVAC is activated, the fan/blower continuously makes a loud and annoying squeaking/chirping sound. Until next service, its a choice between irritating noise or comfortable cabin temperature."

Anonymous, UT (2012 Mercedes-Benz E-Class E350 3.5-L V6)

Drive System

Driveshaft or axle, CV joint, differential, transfer case, four-wheel-drive/all-wheel-drive components, driveline vibration, electrical failure, traction control, electronic stability control.

What Owners Say

"preventative maintenance due to age deterioration; problem resolved on routine maintenance visit"

Anonymous A., GA (2012 Mercedes-Benz E-Class E350 3.5-L V6)

Transmission Major

Transmission rebuild or replacement, torque converter, premature clutch replacement.

What Owners Say

Transmission rebuild or replacement

"Shortly after buying this vehicle pre-owned at 65000 miles, we learned the radiator was leaking coolant into the transmission and that caused the transmission to need replacement. The cover under the bottom of car prevented us from discovering any leaks and we did not have a mechanic check the vehicle before purchase because we bought extended warranty. Very costly mistake."

Anonymous, GA (2012 Mercedes-Benz E-Class E350 3.5-L V6)

"Sometimes it chatters while shifting"

Anonymous, GA (2012 Mercedes-Benz E-Class E350)

Engine Minor

Accessory belts and pulleys, engine computer, engine mounts, engine knock or ping, fuel leaks, oil leaks.

What Owners Say

Oil leaks

"Oil leak was discovered at a maintenance appointment. No sign of oil leaking in my garage because MERCEDES-BENZ has cover under engine that prevents driver from seeing fluids leak on ground. Oil leak from several areas as the integrity of the seals deteriorated before 100,000 miles. This was a major repair that costs about $9000 on a vehicle that was not worth $9000."
