The problem is the name of the member variable not the private access modifier. The variable name is supposed to be mBarsCount:

public class GoKart {
  public static final int MAX_BATTERY = 8;

  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public String getColor() {
    return mColor;
  } 
}

Your code is actually fine. The problem is in the details of the challenge. It explicitly asks for a variable named mBarsCount. You've used mBattery. If i change out your mBattery for the correct variable name ... it passes. Here's the code:

public class GoKart {
  private String mColor;
  public static final int MAX_BATTERY = 8;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public String getColor() {
    return mColor;
  } 
}
