Chassis, brakes and all under carriage of 2004 Toyota 4 runner is rusted. Soon the car will not pass inspection. I do not live in a salt water zone. My car has never driven through salt water. I have 71,000 miles on the car. The brakes were so rusted that I had to replace them. The car will be too dangerous to drive soon.
Kings Toyota dealership informed me that the frame is rusted so severely that it is unsafe to drive the vehicle. Service technician says rust is so bad they cannot put it on a lift. .
Had a misfire in #6 cylinder at 155k miles. I took it to a dealer and they told me that I had a head gasket starting to go bad that let coolant into that cylinder after I shut the engine off resulting in a rough cold start. The tech specialist gave me some nice information and after research I learned Toyota knew about the faulty head gaskets in their vehicles and came out with a new redesigned one, but they never told consumers and refuse to fo anything about it. Now my car is in the shop and quoted at $3200.
Blown head gasket at 150k miles. Potential to overheat to overheat while in operation leaving the passengers stranded or start an engine fire. Every local mechanic shop I received estimates from in knoxville was very familiar with this issue for this model year and the internet forum searches have hundreds of complaints for this same issue. No recall has been issued for this problem.
Blown head gasket with 130,000 miles. Blown near the number 6 cylinder (like everyone else). Cost $3700 for repairs.

Vehicle engine light and other lights came on, took to dealer and told me code was po306 code was diagnosed stating there is a misfire in cylinder #6 resulting in a head gasket problem of coolant entering the cylinder & it would cost me 3000 to 5000 dollars to fix. Every time I start car in morning the car has a rough shacking start until warmed up, my car has 135000 miles & reviewing online this is a common problem with this engine around or after 120000 miles and that their are hundreds of complaints with the exact same issue I am having. Please can one get help in getting Toyota accountable for a problem they surely know about as well as because I am not the first and probably not the last on complaining about this issue & that this is not a normal problem for this engine it is a manufactures defect.
After reading online there are hundreds of reports of cylinder #6 failing with a head gasket issue which results in a 2500-4000 $$ repair bill. Toyota had a major recall for the 2nd generation 4runner because of head gasket issues. They really need to address this issue b/c there is obviously a major problem with the 2004 4runner v6 engine.
Rotten egg smell from rear of truck. Worse with rear window open.
This incident was 1st noticed 12/9/2009. I started my car in the morning and let it warm up, when I went to get in it a few minutes later, the heater fan would not work. Since then, I find that the heater fan will work off and on, seems to be after vehicle has warmed up a bit -maybe (not sure of the rhythm or reason). I do not feel safe driving this vehicle in cold weather especially since I have small children and fear getting stuck or stranded with no heat! I purchased this vehicle in December of 2008 and drove it all last winter with no problems-therefore I am concerned as to when and where it will malfunction again.
Vibration is felt in steering wheel at highway speeds (55 mph or higher). This is especially present when steering wheel is turned slightly to the right. Have had tires rebalanced with no change in vibration. Problem has been with vehicle since purchase. Tire replacement and rotation does not correct vibration.
Annoying engine or drive train vibration between 1400 and 2000 rpm. More noticeable on upgrades. Releasing accelerator pedal results in eliminating the vibration as the engine speed decreases. The vehicle is a 2004 Toyota 4 runner v8 limited. This issue was initially noticed at about 700 miles on the odometer.
