What owners report

Owners of this model year report a wide spread of problems, but the dominant theme in sampled complaints is airbag-related: several describe airbags that did not deploy in a collision, and many more describe waiting for parts under a Takata driver-side inflator recall. A second recurring group covers engine driveability — hesitation, misfires, stalling and oil entering the wiring harness — plus transmission behavior, fuel odor near the tank, and electrical drains or fires. Complaints arrive across a wide mileage range, from a few thousand miles to well over 100,000.

  1. Air bags

    Waiting on Takata airbag parts

    • 42 complaints (49%)
    • median 109,000 mi at 13.3 yrs old (9 state mileage, few)
    • 5 mention a crash, fire or injury
    • filed 2006–2024

    A large share of sampled complaints are about the recall process rather than a failure: owners received notice of the driver-side inflator recall but were told the parts were not available, sometimes for a year or more. Several describe the airbag warning light flashing randomly, and some say a dealer quoted a diagnostic fee before ordering parts. None of these owners reported an actual inflator failure. Mostly reported from 2016 through 2019, on cars whose odometers are not stated in most complaints.

    Recall 16V0810002 related service bulletins

    What to check: Ask for written confirmation that the recall remedy was performed, not just that the car was inspected. A randomly flashing airbag light is worth diagnosing.

    2 excerpts from owner complaints in NHTSA records

    “Takata recall. I called mercedes benz of USA on april 24, 2018 to request information as to when the vehicle identified above would be scheduled to have its affected airbags replaced. Their response indicates that I am in for a very long wait. Their priority of replacement focuses on vehicles in humid environments. The vehicle described above was originally purchased in and spent a significant period of time in boston. Ma. I am concerned about possibly being mortally wounded by the current airbag in an otherwise non-fatal accident.”

    NHTSA complaint #11090180, filed 2018-04, 138,000 miles

    “My car is subject to the takata airbag recall and the dealer has not offered me any repairs or any accommodations since march 2016. I purchase the car from euro motors bethesda. Euro motors bethesda refuses to give me a loaner car. Please help me I need a car and I don't feel that my car is safe to drive.”

  2. Air bags

    Airbags did not deploy in a crash

    • 18 complaints (21%)
    • median 83,309 mi at 10.3 yrs old (13 state mileage)
    • 10 mention a crash, fire or injury
    • filed 2005–2024

    Owners describe frontal, side or rollover impacts in which some or all of the airbags failed to inflate, sometimes after the SRS warning light had come on beforehand. Several say a dealer had already serviced the SRS system or replaced a seat belt tensioner under warranty before the collision. Complaints also describe the driver taking the car in for SRS diagnosis and being told that a wiring harness or control unit needed replacement. Reports span roughly 2,000 to 140,000 miles, including cars only a few years old at the time of the crash.

    Recall 16V0810005 related service bulletins

    What to check: Confirm whether the Takata driver-side inflator recall has been completed and ask for the repair paperwork. Have any SRS warning light or stored SRS code diagnosed before purchase.

    2 excerpts from owner complaints in NHTSA records

    “My family and I were hit in a car accident head on by a driver going approx. 60 MPH. Our mercedes benz C230's airbags did not deploy. The car was equipped with 6 air bags and not 1 deployed. We have contacted mercedes but to no avail. We would like some help as what to do to make sure this does not happen to another family and they may not be as lucky as we were.”

    NHTSA complaint #10383162, filed 2011-02, 74,532 miles

    “I was involved in a 1 vehicle accident where the driver, left curtain and left side airbags were deployed. Upon close examination of the failing driver's airbag, I found obvious signs of perforations and burn-through. I was injured on my chin, face and forehead. This airbag was just recently replaced under recall campaign at the end of october this year, part of the takata ordeal.”

    NHTSA complaint #11154382, filed 2018-11, 90,000 miles
  3. Engine

    Oil in the engine wiring harness (camshaft solenoid leak)

    • 8 complaints (9%)
    • median 68,000 mi at 3.7 yrs old (7 state mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2006–2023

    Owners report the check engine light coming on, rough idling, misfires, stalling and multiple stored fault codes, and say a mechanic traced oil that had leaked from the camshaft adjuster solenoids into the wiring harness and control module. Complaints describe the harness or connectors being cleaned or spliced as a workaround. Others report hesitation and loss of power on acceleration that returned after several dealer visits. Reports cluster between about 20,000 and 140,000 miles, with many in the 50,000 to 120,000 mile range.

    1 related service bulletin

    What to check: Look for oil residue at the camshaft solenoid connectors and in the harness, and ask whether the solenoids or harness have been serviced. Have stored engine codes read before buying.

    2 excerpts from owner complaints in NHTSA records

    “I have been notified about the safety air bag recall however, I have just found oil in my wiring harness. My car is idling very rough and stalling, the check engine light is on, I received 8 codes. I have oil in my camshaft wiring harness, my piston 1 fuel inject, spark plugs, and front of the engine where camshaft adjuster magnets are covered in black sludge oil. …”

    NHTSA complaint #11185733, filed 2019-03, 110,000 miles

    “My mercedes benz C230 kompressor started having problems at 4400 miles, it has a hesitation problem. It now has 42,000 miles and still has hesitation. Its been in the shop 7 times for the same situation. They tried to blame it on water in the fuel, but it continues to have the same issue. Over the seven attempts to repair my vehicle, the problems still persists. The hesitation is consisted of stopping and going, jerking the vehicle when transmission from gear to gear. Its a fuel related problem. …”

    NHTSA complaint #10204835, filed 2007-10, 4,405 miles
  4. Transmission and drivetrain

    Transmission slips, surges or will not hold a gear

    • 6 complaints (7%)
    • median 90,271 mi at 7.7 yrs old (6 state mileage, few)
    • filed 2007–2018

    Complaints describe the transmission shifting up and down on its own, dropping into neutral at speed, losing power, or shifting into reverse unexpectedly. Owners also report hesitation and jerking between gears on acceleration and, in some cases, a clunk from the rear when changing direction. Several say a shop diagnosed internal transmission or sensor faults; others describe repeated visits without a lasting fix. Mostly reported between about 60,000 and 100,000 miles, though a few appear much earlier.

    4 related service bulletins

    What to check: Ask whether the transmission has been serviced and whether any fault codes or a pilot bushing repair are documented. Drive the car from a stop and through a firm acceleration to feel for slipping or harsh engagement.

    2 excerpts from owner complaints in NHTSA records

    “Driving in to work on the highway I was doing about 70 MPH and suddenly I felt hard jolt and the car began to slip and swerve. There had been snow storm the night before and the roads were wet. I manage to control the car and pull over to the emergency lane. The transmission had shifted down for some reason, causing the wheels to slip. Shifted the car to p and back to d but the car had no power. Shifted a few more times and finally I was able to drive into work but the transmission continued shifting up and down unexpectedly. …”

    NHTSA complaint #10381936, filed 2011-02, 110,000 miles

    “I pulled up to a stop sign and as I preceded to accelerate it was very shaky and unwilling to accelerate. It would not brake 20 MPH. I then pulled over and shut the car down and waited to restart. After the restart it behave as normal but if I accelerated to much it would begin to shake and would not accelerate anymore. After some research on the forums I discover a mass of similar complaints that match my description to a t and describe issues with a cam bearing, a transmission plate, or both. Thank you for your time and consideration. …”

    NHTSA complaint #10509805, filed 2013-04, 82,543 miles

Buying note. Check the recall status in writing for the driver-side inflator and the sunroof glass panel before purchase, and have any SRS, engine or transmission codes read. A pre-purchase inspection focused on the camshaft solenoid area, the transmission behavior and the fuel tank would be worthwhile on a car of this age.

Example complaints

Air bags: “Takata recall: I had a front end collision and I am concerned that my airbags did not deploy. The impact in my opinion was such that caused me to wonder why they did not inflate. My primary concern is if they work at all. My car was in motion on a wet highway at the time of impact around 2pm. The consumer stated the vehicle should have been included in the sunroof recall. While driving the vehicle at 60mph, the sunroof shattered. The consumer was informed that due to the sunroof exploding, the recall did not apply.”

NHTSA complaint #10854507, filed 2016-04, 109,000 miles

Electrical system: “I purchased the car and about 1 week later the battery had drained. I purchased a new one then about 3 weeks later it drained again and again and again. It keeps draining no matter how many times I replace it. I have only put about 200 miles on the car since I purchased it years ago because of this. I replaced the tires once and the battery numerous times. I paid $6,500.00 for a car I can't even drive.”
