Owner report 11434449 · 2021-09-27 (September 27, 2021)

While driving on an interstate highway, I received a yellow "48V Battery malfunction" notice. Because this battery had failed before, I had read on internet forums that the car could just stop working, so I took the next exit (about 3-4 miles). At the top of the ramp, I had a red "Battery Malfunction" (red=stop driving); then, within 15 seconds the car had no power and gave me a critical "engine overheated" message. I was able to coast into a parking lot. Had I not exited, the loss of power would have likely resulted in an accident and we …

Owner report 11580697 · 2024-04-02 (April 2, 2024)

My car started shaking and after putting it on the computer it was an electrical wiring harness issue. I was told it will be 6 k to replace both harnesses. It’s been 8 months and they just received the part. The service tech told me that these cars have this issue due to the position of the harnesses being to close to the exhaust. It dries out the wiring. I went to the Mercedes forum and found numerous complaints about this issue. Recently I baited the Mercedes of downtown Los Angeles and was advised they received another cls 450 with the same …

Throughout the course of my ownership the vehicle has had multiple sets of tires replaced due to them either being prematurely bald, developing multiple bubbles, or shredding due to cracked rims. Along with the tires being constantly replaced, I have had to replace 8 rims that have cracked under normal driving conditions.

This led to the loss of air pressure in the tire. The tire pressure sensor did indicate a low pressure condition. Upon inspection of the rim, the only possible solution was to have it welded in order to continue the trip.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
