I was trying to pass a car doing a little over 55 mph and heard a loud bang noise. I pulled over and stop the as as quickly as possible. The oil light came on and there was oil was pouring out from underneath the motor. The oil service was kept up to date and was just changed. The car was towed and the engine had thrown a rod. Motor needed to be replace. (after doing some research this seems to be a problem with 4 runner engines when they reach 75000 mles or more. I am not alone in this problem. ) I was lucky that I didn't get into an accident and that I wasn't on the expressway in chicago. I have emailed Toyota.

Steering has knocking sound while turning left or right, it started at about 62000 miles. Also replaced coil pack #2 and # 4 at 49000 miles had another go out a year later, delership told me to replace the remaining 4 coil packs, by only replacing the corruped one will cause the ohers to fail.

Driving car and heard loud bang noise car immediately starts slowing down and oil light comes on after car stops oil is pouring out from underneath the motor. We send car to the dealership they say the engine has thrown a rod. Motor needs to be replaced the car has 72,000 miles on it . A person in the service dept says they have had a lot of problems with this motor it is very weak. We call other mechanics to get estimates they say they to have seen a lot of problems with this motor. We haven't done anything with the car we are still hoping for some help from Toyota. Also we gave the dealership all of our oil change records that were done on time.
The contact stated the vehicle stalls and the dealer has been unable to resolve. The contact is unsure if this is the engine and the transmission. The vehicle also has a continuous knocking sound, and a intermittent stalling problem. Also the vehicle has a vibration when it is accelerating over 50 miles per hour.
