We expect the 2025 4Runner will be more reliable than the average new car. This prediction is based on the previous generation of the 4Runner and the Toyota brand score.
The Reliability score is based on our latest subscriber survey of 2006 Toyota 4Runner owners. The owner comments describe problems respondents experienced with this vehicle.
Driveshaft or axle, CV joint, differential, transfer case, four-wheel-drive/all-wheel-drive components, driveline vibration, electrical failure, traction control, electronic stability control.
Paint (fading, chalking, peeling, or cracking), loose interior or exterior trim or moldings, rust.
"We bought this used car last year with only 40k miles on it. When it came time for our state I spection renewal we were told that the frame was rusted and had soft spots - wouldn't renew inspection. We were told that we should've known about Toyotas rusting frame problems. This car was pristine - garage kept had all service records and was rarely driven. It belonged to an elderly woman who only used it in the winter. She paid $33K for it in 2006 - brand new. Only put 40K miles on it & the frame is rusted out - unsafe. Unacceptable. Toyota should be ashamed..."

"Brake line broke due to age & wear. Car seemed to be operating fine, it had been inspected only a few weeks prior to the incident and earlier in the day, Id driven down quite a steep hill and stopped at the bottom with no problem. With no previous warning, the brake alarm light on the dash started flashing and making warning tones, and I realized I had virtually no brakes. Luckily I was in a flat parking lot at the time so was able to coast to a spot out of traffic flow & call to have vehicle towed."
