  • Predictable handling and well-tuned suspension

  • Comfortable, well-built cabin

Traits Linked with Unreliable Cars

  • Transmission problems; sluggish steering

  • Poor fuel economy; noisy, bumpy ride

  • Noticeable performance shortcomings


Model Snapshots

2019 Toyota 4Runner

A standout for durability—owners routinely rack up high mileage with minimal major issues. Top reasons buyers choose 2019 models include rugged capability, easy drivability, available 3rd-row seating, and a tough, body-on-frame design.

2020 Toyota 4Runner

Widely regarded as highly reliable. Toyota added standard Toyota Safety Sense P (TSS-P) across the lineup, including adaptive cruise control, lane-departure warning, pre-collision with automatic braking, and automatic high beams. See details at Car and Driver and Consumer Reports.

2021 Toyota 4Runner

  • New limited-production Trail Edition with TRD wheels, black exterior badging, tan-stitched seats, and all-weather floor mats

  • Newly standard LED headlights

  • TRD Pro updates: Lunar Rock color, new TRD wheels with Nitto Terra Grappler tires, retuned dampers for better isolation off-road


Why the 4Runner Scores Well

  • Owner community & documentation: Clear maintenance schedules and huge knowledge base help keep trucks in top shape.

What to Check When Buying Used

  • Complete maintenance history (oil changes, coolant, transmission, diffs/transfer case on 4x4 models)

  • Frame and underbody corrosion, especially on older/high-mileage examples

  • Suspension wear (bushings, shocks) if used off-road or for towing

  • Functionality of 4WD system and safety tech (TSS-P on 2020+)

  • Independent inspection and a vehicle history report (Carfax/AutoCheck)
