2003 Toyota 4 runner problems

Common 2003 Toyota 4 runner problems

The Toyota 4Runner, a popular SUV, has had its fair share of problems over the years. The 2003 model year, in particular, has been identified as the worst for body and paint issues.

In addition to rust and corrosion issues, the 4Runner has faced problems with its airbag system. For instance, the 2015 model year has been reported to have issues with airbags failing to deploy in accidents, which can cost an average of $9,000 to fix at an average mileage of 15,000 miles.

The 4Runner's automatic transmission has also been a source of problems, particularly in models produced between 1990 and 2011 and in the 2016 model year. Owners have reported issues such as the SUV reverting to manual shifting, not shifting into overdrive, or not shifting into drive at the initial start-up, leading to a loss of power and rough shifting.

The 4Runner's braking system has also been problematic, particularly in the 2017 model year, where many owners have reported temporary failure and brakes locking up for a short period on one side of the SUV.

The 4Runner's starter solenoid has also been a source of problems, particularly in the 3rd and 4th generations of the SUV. Corroded solenoid contacts can result in the SUV suddenly stopping or refusing to start altogether, with many owners reporting unusual ticking sounds when attempting to start the vehicle

. Most of these issues have been resolved by replacing a faulty starter, with a starter solenoid replacement costing around $50 to $200 plus labor costs

The 4Runner's exhaust manifolds have also been a source of problems, particularly in the 4th generation models produced between 2003 and 2009. The manifolds can rot quickly, leading to expensive repairs, as the front converters are attached to the manifold

. This issue can be particularly problematic in the 2003 model year, where the manifolds are known to crack at the manifold and the little piece that goes into the head, requiring replacement

The 4Runner's frame has also been a source of problems, particularly in the 4th generation models produced between 2003 and 2009. Toyota did not issue a recall for the 4Runner's frame, despite similar recalls for the Tundra and Tacoma models.

In summary, the Toyota 4Runner has had its fair share of problems over the years, particularly in the 2003 model year, which has been identified as the worst for body and paint issues. Rust and corrosion, airbag system failures, automatic transmission issues, braking system problems, starter solenoid issues, exhaust manifold problems, and frame issues have all been reported by owners of the 4Runner. While the 4Runner is generally considered a reliable SUV, it is important for potential buyers to be aware of these common problems and to thoroughly inspect any used 4Runner before purchasing.
