Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

2007 Toyota 4Runner Owner Comments

problem #17

Jul 292014


  • miles


Over the past 9-12 months I have owned the 4runner, I have noticed the floormats slide up behind the brake and acceleration pedal when I am constantly switching between the two (eg. Heavy traffic, long trips, etc.). I usually am able to pull them back down at a stoplight or stop sign; however, on Tuesday, July 29th, I was involved in an auto accident that was not only in heavy traffic, but while on a 200+ mile trip as well. I believe that the floor mat caused my car to have limited braking ability in addition to possible increased acceleration. The NHTSA's findings seem to be consistent with this. Additionally, the complaint with NHTSA id number: 10384563 states that "I pushed on the brake... but the car continued accelerating" and then "Toyota inspected the vehicle... and said they adjusted the mat" is one of many that have findings consistent with the malfunction that caused my wreck.

When the air conditioner is running the vehicle idles at different RPM's causing it to lunge forward when the A/C compressor shuts down, increasing the RPM's. this has almost caused a fender bender several times while at a stop light.

This was the fourth occurrence of unintended acceleration. Each incident occurred upon shifting from park into either reverse or drive. The engine revved up to the red line upon shifting from a stopped position. This occurred with both a cold engine and a warmed up engine. I slammed on the brake and shifted into neutral. The accelerator pedal did not depress. Pressing the accelerator pedal in neutral brought the idle back to a normal levels.

I experienced a sudden acceleration on 10-5-10 in my 2007 Toyota 4runner, 4WD. As I was turning onto a busy street at an intersection with lights, I pushed on the brake at the stop sign as the oncoming traffic approached, but the car continued accelerating into the lane at the intersection, and I pushed as hard as possible on the brake. I pushed the gear lever forward as the oncoming car veered into the next lane to avoid me. Continuing to push on the brake, I shifted into reverse, but the acceleration was still active and my tires squealed in reverse, so I shifted down into neutral and stopped, and the traffic had stopped also. Since the acceleration stopped I was able to drive normally, and there was no collision, thankfully. Toyota inspected the vehicle as usual, finding nothing, and said they adjusted the mat and that was that. I emailed the general manager about my situation and he said he would look at it again. I said I am aware of the intermittent problem with the electrical accelerator and would like to have him buy my 2007 and sell a 2011 4runner with the "smart pedal" technology. He agreed and now I own a new 2011 4runner.

The incident happened at the intersection of harbison and division St. Southbound at harbison St.,while slowing down for a full stop at a red light with my right foot gradually pressing the brake pedal suddenly the engine RPM went up so high without stepping on the accelerator pedal. My immediate reaction was to press harder the brake pedal. The high acceleration lasted about 10 seconds and I was able to bring the vehicle to a full stop at the middle of the intersection which have caused an oncoming vehicle at my leftside to swerve to its left to avoid an impact. This is the second time it occurred. The first time it happened with another driver it was ignored because he thought it was normal. There was no repair done on both times it happened. The owner have not receive any notice of manufacturer notice of defect. The first incident was about 6 months ago and not reported. Also no fire, property damage, crash occurred.

We own a 2007 Toyota 4-runner, bought new in Oct. 08, that has sudden burst accelerator problems. When setting at a traffic light or another stop, truck will suddenly surge forward while foot is on the brake. It happens every time it is driven, at some times stronger that others. Have spoken with the dealership on numerous occasions, to no avail.

We were stopping for a red light in the left turn lane. We started to slow down and then our vehicle just took off and we rear ended a truck. Didn't hurt the other truck but the front end of our vehicle is smashed and our bumper is cracked. The dealer told us to take out our mats so we did. We recently called the Toyota experience line and they gave us a claim number but said sorry we are not on the list of recalled vehicles. We are scared to drive our vehicle.

I bought a 2010 Toyota Camry in Sept. I called my dealership 2 weeks after I bought it noticing that my car revs up for no reason & doesn't shift right. I contacted another Toyota dealership recently about it not shifting right & they said they have had several complaints about the same thing. My mom has a 2007 Toyota 4-runner & the gas pedal stuck 3X on her & my stepdad last summer on the interstate. Not knowing what to do, he turned off the ignition & coasted to the side of the interstate. They contacted marion, il Toyota dealership where they bought it & they gave my parents a hard time & was very hateful. After the 3rd time they finally cleaned the "throttle body" & hasn't done it since yet she hasn't drove it much since she is scared for her life. She has been an avid Toyota owner. She has owned 3 4-runners and is thinking about going to something else mainly also because her dealership is being hateful about all of this. I'm scared for her & of course for myself since the Toyota 4-runners are not on the recall list.

I was waiting in line of traffic to pick up my daughter at school. Car was in drive, my foot was firmly on the brake pedal, when the engine suddenly raced and the car lurched forward about 10 feet. I stomped harder on the brakes and the car did stop, but at no time had my foot ever left the brake pedal, and was not even remotely touching the gas. At first I thought the car had been hit from behind, but when the incident was over, I realized that was not the case. My wife observed the incident from the passenger seat and concurs that my foot was on the brake the whole time. She later checked to make sure that the mat had not shifted to press on the gas, but confirmed that nothing was in contact, or even near the gas pedal. My wife took the car to the dealer the same day to check the computer codes, but nothing was recorded in the history. Dealer was unable to observe the phenomenon. The check engine light did not come on. I purchased the car new in October 2007. Mileage at the time of the incident was 19,912.

Vehicle surges forward when air conditioner on. Hazard at traffic lights. Will drive itself forward up hills and along flat roads without accelerator being touched when ac is on. The higher the ac fan speed the faster the vehicle goes. Dealer does not have "computer program" to fix. This is a safety hazard.
