boolean recalled;

((modelYear>=1999 && modelYear=2004 && modelYear<=2007 && modelName=="Guzzler")) ? recalled = true : recalled = false

Explanation:

Using a combination of comparison operators and logical operators, the conditions stated in the question is captured in the code snippet with the boolean variable recalled also declared. Since we are not allowed to use the if statement, we have used the conditional or ternary operator that checks if a condition is true executes the statment that follows the question mark else it executes the statement after the full colon.
