Vehicle displayed a check engine light due to a non sealing gas cap. This condition also disables the stability control system. Vehicle lost control on wet conditions and was unable to recover due to all traction and stabilization systems being turned off due to a check engine light (faulty gas cap). I have owned the vehicle for 6 years and have put over 80,000 miles on it without incident. Vehicle was in motion traveling the speed limit on a rainy road.

Entire underbody of car is rusting out, tail gate already had 2 body repairs but keeps rusting out. Many parts at just 150K were already replaced due to severe rust- most suspension parts, transmission cooling lines, exhaust, skid plates all failed. Brake calipers failed 4 times in in 6 years.

I have gone through 2 sets of front brake calipers on my 2008 Toyota 4runner. It is a common issue where over time, the calipers will seize up and stick on. The only way to tell that there is an issue is either by touch, smell, or feel. Touch, because the rotors get to be over 250 degrees and they cannot be touched. Smell, because the smell of burning brake pads is present feel, because there is a loss of braking. Other than these indications, there is no notice of seized calipers until it is too late. This is a common issue and has happened with most 4runner owners that I talk to. I'm surprised that this has not become an issue.

When braking, any bump or pothole will cause the system to lose brake power for about one (1) second, causing the vehicle to continue at the same speed for tens of feet further than expected. Hidden potholes by standing water can cause the vehicle to travel into an intersection or other vehicle. This is the third 4-runner that I have experienced with the same problem. Previous vehicles were from 1994 and 1998, and I had three rear-end accidents, which caused major damage to the other vehicles.

During a maintenance visit to East coast Toyota of carlstadt, NJ an "update" to the ECU computer system was performed. After this "update" I noticed the engine stalling, then recovering and auto then surging forward. This was explained by Toyota as "smart technology" to modify eng/ect system. In my opinion this is a dangerous "fix": example --when trying to enter a traffic lane from a dead stop, with foot on break if you attempt to accelerate the engine cuts out- sending you into traffic with a lag instead of a power boost. I attempted to have this modification undone by Toyota but they explained their position as below: We apologize for your concerns with the smart stop technology installed in your 2008 Toyota 4runner. As we previously indicated, in response to customer's concerns with their vehicles, Toyota worked with the National Highway Traffic Safety Administration (NHTSA) to come up with this remedy, which is the installation of the smart stop technology. Because this remedy was mandated by the government (NHTSA), we are unable to remove the smart stop technology. Your email has been documented at our national headquarters. In my opinion this change doesn't fix anything - it is dangerous- you can't accelerate from a "holding" break position (foot on break and gas) as recommended by some defensive driving instructors.. I am requesting that the ntsb looked into this Toyota modification (before update code 33562000, after update 3356200), determine it's efficacy (or lack of ) and devise a better fix than their so called "smart technology".

There is corrosion in the frame and drive-train components. There is pitting, rusting throughout the frame undercarriage and the suspension and differential components. This barely 4yr old vehicle is a southern vehicle. Regardless, this corrosion is a safety issue in any vehicle let alone in a 4runner with a service inception date of 11/30/2008 with 19K miles. This is totally irresponsible of the manufacturer and they claim it is not covered by warranty. Yes, it (should be) covered by warranty and more importantly it is manufacturer's liability to correct safety/quality issue.
