The Toyota 4Runner, a rugged and capable SUV, has earned a reputation for its durability and reliability. As the 2025 model year approaches, potential buyers are eager to understand the engine’s reliability and how it stacks up against its predecessors. While official data won’t be available until after the vehicle’s release, we can delve into the existing information and trends to offer a comprehensive analysis.
A Look Back: The 4Runner’s Engine Legacy
The 4Runner’s engine history is a testament to Toyota’s commitment to robust and dependable powertrains. Throughout its generations, the SUV has been equipped with a variety of engines, each with its own strengths and weaknesses.
-
The V6 Era: The 4Runner’s popularity surged with the introduction of the 4.0L V6 engine in the early 2000s. This engine, known for its smooth performance and durability, became a staple in the 4Runner lineup. It was renowned for its ability to handle off-road adventures while providing comfortable on-road driving. However, some owners reported issues with oil leaks and valve seal failures, particularly in older models.
-
The V8 Interlude: For a brief period, the 4Runner was offered with a 4.7L V8 engine, primarily in the TRD Pro trim. While this engine delivered impressive power and torque, it was known for its higher fuel consumption and maintenance costs. Its reliability was generally good, but some owners experienced issues with fuel injectors and spark plugs.
-
The Modern 4.0L V6: The current 4.0L V6 engine, introduced in 2009, has proven to be a reliable and efficient powertrain. This updated engine addressed many of the concerns associated with its predecessor, boasting improved fuel economy and reduced emissions. It remains a popular choice for its blend of power and efficiency.
