| Mercedes-Benz E-Class in Texas, United States May 2011 - Jun 2018 | |||
| May 201221300 miUS $495 | I felt alignment out of spec and had the system checked. They replaced 3 bolts and said it's done but I still got the same problem. Figured out that E-Class "drifts" more than normal becuase of light steering. Common occurrence. | ||
| Jun 201222000 mi | Car didn't start in morning. Checked & Battery was good. Took the car to dealer and they checked it out. Said AC system doesn't shutdown properly and needed a software update.

| Apr 201898000 miUS $950 | Front tires needed replacement after getting worn out from the inside edges due to bad alignment. It is a repeat "feature" - the car seems to eat either the front set of tires or the rear one. Driven 8 miles daily. No harsh turns or breaks whatsoever. But the issue keeps on coming up in 8-10K miles. And its either the front set or the rear. Car is always dealer maintained and all reports show alignment as correct and other components working as required. IF anything is off, i get it replaced immediately. This is my wife's daily driver and I don't like her or kids stranded on road side so I maintain it religiously. | ||
