| Engine is leaking coolant into the #6 cylinder causing misfire, rough idle, and check engine light to illuminate - apparently a very common problem with this v6, 4.0l engine leaking at the #6 cylinder - obviously a manufacturing defect to have head gaskets failing at the same location. *tr | |||

| 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. *tr | |||

| Excessive sulfur smell when accelerating. occupants of the car can smell the sulfur, and all windows must be rolled up in warmer weather to block out smell. i have taken the vehicle to the toyota dealership, but they will not fix the problem because there is no tsb for the v8 (but there is for the v6) toyota 4runner. *jb | |||

| After 2.5 years and about 25000 miles, my 4 runner sport develops a strong sulfur odor inside the cabin when driving. brought the car to the dealer (caldwell toyota) in west caldwell, nj who informed me the problem was normal and caused by the type of fuel used. caldwell toyota had no answer to my question why the problem suddenly surfaced after 2.5 years nor did they offer to further investigate. the caldwell toyota technician could not explain how the sulfur smell from the exhaust, which should be contained within the engine and should only to be expelled from the car through the muffler entered, the cabin while driving (seems physically impossible). the strong sulfur odor inside the cabin causes nausea, light headiness and general discomfort, which distract me from driving. this problem should be investigated as a potential cause for toyota 4runner accidents. *jb | |||
