2007 Mazda 3

The 2007 Mazda 3 is a compact car known for its sporty handling, stylish design, and affordability. It was available with two engine options: a 2.0-liter inline-4 producing 148 horsepower and 135 lb-ft of torque, and a 2.3-liter inline-4 generating 156 horsepower and 150 lb-ft of torque. Transmission options included a 5-speed manual and a 4-speed automatic (with the 2.0L engine) or a 5-speed automatic (with the 2.3L engine). Owners often praise the Mazda 3 for its engaging driving dynamics and fuel efficiency. Common complaints include issues with rust, electrical glitches, and some reliability concerns as the vehicle ages.

Engine

2.0L Inline-4

  • Excessive Oil Consumption
    • Description/Symptoms: Some owners report higher-than-normal oil consumption, requiring frequent top-offs between oil changes. Symptoms include low oil level warnings and potentially engine knocking in severe cases.
    • Solution: Check the PCV valve to ensure proper crankcase ventilation. If that does not fix the issue, a mechanic may need to perform an oil consumption test to identify the root cause, potentially involving piston rings or valve seals.
    • Estimated Cost to Fix: $50 (PCV valve replacement) - $1500+ (engine repairs)
    • Recalls: None Found

2.3L Inline-4
