Problems with 2003 Toyota 4Runner ENGINE AND ENGINE COOLING

While driving moderate to heavy acceleration with all windows up and internal air circulation there is a strong rotten egg/sulfur type smell??? this is on a 2003 limited 4-runner bought new in maryland;darcars;this is very irritating and makes my kids 10yrs and 11 yrs. old sick. very confused what is causing this??????? please help..*jb

The exhaust smell from the truck has a horrific and sickening smell. i have not been driving the vehicle due to this issue. it has made me sick to my stomach at times and my wife and kids can not stand the continuous smell either. i am very upset with this and would like a refund of my purchase price. toyota sent out a tsb regarding the smell saying it was the gasoline (poor) that people use. wrong! i use amoco and texaco only. *ak

My 2003 4runner v6 limited generates this unusual engine noise especially when accelerating. my observations include a possible loss in power and affects engine performance, and possibly the longevity of the engine. i took it to a second toyota dealer where it was immediately recognized but a solution is yet to be determined since the v6 4.0 is a new engine. currently, i wait for a toyota technician from the factory to examine the engine. meanwhile, i continue to drive the vehicle and i am afraid that i am doing more harm to it's life expectancy. what steps can i take to accelerate the process since i feel that i am being given the runaround. i have been a faithful toyota customer as this is my 3rd 4runner, and have never experience anything like this. many thanks. *nlm

Toxic sulfur/rotten egg smell in cabin of automobile

The sulpher smell/carbon monoxide that comes into the cab of my '03 4runner v8, is extremely unacceptable. this is my 4th toyota in the past 6 years and i have never been more dissapointed with my vehicle. took it to 4 dealers to all say to me that it's a gas grade issue. i'm tired of toyota not standing behind their product and helping loyal customers out with annoying issues. at the very least, offer an altenative system.

In december of 2002, we purchased a 2003 toyota 4runner sport. almost immediately we noticed a strong sulphur smell leaking into the cabin when the vehicle was in motion. we took it to back to peformance toyota where we purchased it and had it checked out. the maintenance manager said that the vehicle checked out fine, handed us a copy of a service bulletin #eg003-03 and suggested we change gas. we tried every gas at every gas station we could find and it only got worse. my wife had been using the vehicle to car pool our two daughters, along with other children, home from school. one of the children got physically ill (we later found out that he suffers from migrains, and the odor was triggering his attacts), so we had to pull our daughters out of the car pool. in order to limit my daughters' exposure to sulphur dioxide, i agreed to use the toyota and let my wife use my dakota to take the girls to/from school (it doesn't stink). after driving the toyota to work for close to a year now, i have experienced health problems and have recently been diagnosed with asthma by my physician (which i've never had before). my asthma medication costs me $158 per month and i have researched causes of asthma, and have found that this sulphur smell is a possible trigger for it. i have since purchased a used vehicle to drive back and forth to work, and the $37,000 toyota sits in the garage because no one can stand to drive it. help!!!!! *ak

I own a 2003 toyota 4 runner purchased in october of 2002. it emits a horrible rotten egg/sulphur smell into the cabin, windows up or down. has given my passengers headaches and nausea. tried the recommended gas upgrades, nothing works. this is a defect. toyota should be made accountable.*ak

2003 4runner se v8: during accleration, i have exhaust gases entering the passenger compartment. toyota confirmed that the v8 is mostly affected due to the larger displacement engine. also, per toyota, the exhasut gases are entering from a vent located on the left rear of the vehicle. however, toyota insists that this problem is due to the fuel. i have taken this to arbitration and was denied, even thought toyota freely admits to the problem. based on the outcome, i have asked toyota to state that this is a safe condition and was also denied.
