    domino 8, mak9m torek,

    Attorney says only way to handle it now (since Lemon Law doesn't apply anymore because of timing) is to get a signed statement by a mechanic who will also testify.

    Can anyone get this? If so, let's do something together. I heard it could cost $6,000 to sue a manufacturer and you may not get results.

    If your car is less than 1 yr. old and have less than 12,000 miles, keep taking it in to dealer to have it repaired, even if it's every day! Then document it and start proceeding under lemon law.

    I'm seriously looking at other cars now. Honda's smell too.

    See you in Sedans.

    I too have a very strong sulphuric smell using BP 87 oct gasoline in the central Ohio area. This is with a 2000 Toyota Echo with around 2000 miles on it. I brought up the subject over in the Echo discussion and they seemded to think I was just driving the car too hard. I'm taking it in to the dealer within days for a possible diagnosis. By the way, I get the smell hot or cold, short trips or 200 mile trips. (2300 miles in three weeks!)

    Keep taking it in and check into the lemon law, and keep pursuing it. You have 12 months, 12, 000 miles and that's it. File it now! Take car in 10 times, every day if you have to. Try to have them make adjustments and change catalytic converter showing there's somehting wrong. I've been through it, but got screwed.

    Good luck.

    Are you sure it's not the new under coating... The coating looks like black gunk it seems like it takes forever to come off new vehicles. It's not winter so it might be hard for your techs. to get it to act up so you probably need to keep taking it back to the dealer. How is your warranty up 99 is a new car unless you bought it used and only have a limited warranty. When your driving your vehicle beware of plastic bags I have seen more plastic on the Cat than I care to say, an it make a horrible smell that lasts for miles... Does it smell when the vehicle is hot or when you first start it up in the mornings. Maybe you should leave your vehicle at the dealer over night because you said it happened in the winter so maybe they could recreate the problem in the early morning when it's a little cooler...

    I always used Amoco gas. I switched to Exxon and the smell did not come back. I went back to Amoco and the smell appeared again.

    Try changing brands of gas.

    Will be interesting to see what happens when I have my 2000 Jetta inspected in October, 2001.

    To be on the safe side I always ask the dealer to check for the smell so if I do need repairs after the 2 year warranty runs out, I'll have the situation documented.

    Catalytic converters are still hot enough to burn dry things on the ground. That is why cars have heat shields on them now.

    Why heat shields are made out of metal so cheap, it rusts through after only a few years, and somehow costs a fortune to replace is beyond me.
  • These postings are old, but if anyone is still pursuing a lawsuit against Nissan, I'm in. My car smells like rotten eggs everyday and they won't even try to fix it. They have standardized statements that they'll read to me, but they won't discuss the topic openly.

    Someone has to do something about this.......
  • I purchased a 2000 Jetta VR6 back in April and from about 5,000km(Oh yeah, I'm Canadian) to present (15,000km) I've experienced the dreaded rotten egg syndrome. I've brought the issue to the dealer's attention a number of times and they continue trying to convince me that it's the brand or octane level of fuel that I'm burning.

    I've noticed that my tailpipe has been building up with black(carbon) soot which pushes me to believe that the engine is not burning efficiently and I am losing improperly burned fuel out of my tailpipe. Ive owned three vehicles before my Jetta and I've never had a problem with odour nor with black at the tailpipe.

    Has anyone else noticed if this symptom accompanies the sulphur smell from their "special" vehicle?
  • guitarzanguitarzan Posts: 638
    I would say that black smoke is an indicator or a rich mixture. However, soot, along with the smell sure looks like the catalytic converter is not working. Have you gotten second opinions?

    It is true that some of the things they do to gas regionally can make cars perform differently. However, if what they told you is true, every single VW that goes to your gas station would have this problem, and possibly others as well. Kinda doubt that.

    Got another dealer that can give a second opinion? You also might try their customer service line.
  • I have a 1989 Buick LeSabre T-Type with a 3.8
    liter V6 FI engine. My problem is that my car
    sometimes gets that rotten egg smell. I had my catalytic converter replaced a while back in order to pass DEQ, but it still smells bad on a
    consistent basis. Also, it runs really, REALLY bad when I do not warm it up for at least 5 minutes. If I just get in the car in the morning and drive, it seems like I have NO power at all. It will take about 10 seconds just to get up to 20 MPH. The funny thing about this is if I get in the car without warming it up, and then floor it, I get a HUGE surge of power which makes the tires peel out. After that though, it goes back to being slow until I drive it for about 10 minutes. I have spoken with a few of my friends that know "something" about cars, and they seems to feel that it's my mass airflow sensor. If you have some advice for me, I would greatly appreciate it.

    HAS ANYONE FOUND A DEALER WHO HAS SOLVED THIS PROBLEM ? I HAVE A BRAND NEW ESTATE VAN THAT I AM READY TO START LEMON LAW PROCEEDINGS. CHANGING BRANDS OF GAS HAS HELPED SOME BUT IT IS STILL NOT ACCEPTABLE. I HAVE DRIVEN 3 OTHER 2000 VILLAGERS AND 2 HAVE THE SAME PROBLEM TO A LESSER DEGREE. THE DEALER HAS A TECH UPDATE THAT SAYS CHANGING THE CATALITIC CONVERTER MAY MAKE IT WORSE. WHY DO THEY KNOW WHAT MAKES IT WORSE BUT CANNOT FIND THE PROBLEM?
  • tscalzitti, I suspect they may be right. From what you describe, it is running very rich. That would explain high power at full throttle. But, you would also probably smell gas at the exhaust if it is running rich. Also, it would be smoking out the exhaust...?

    Rjt3, make sure and check out the new Villager topics for experienced answers. Good luck.
  • rjt3rjt3 Posts: 2
    my villager has gotten much better with exxon gas and about 4000 miles. there is a re-generated formula which has less sulfer in some areas. it is now to a point which is acceptable, but it's hard to believe that more people don't complain about this.
  • I am a previous poster complaining of this smell in my car. It has increased greatly this winter. I am about to try a couple more dealerships to see if anyone will help me, but then I will proceed with lemon law. I have tried all other suggestions - different gases, different driving habits, EVERYTHING!

    I do not see an end to this situation in the near future.
  • Infiniti is now claiming that unless my car will replicate the rotten egg smell right when I drive to the Infiniti dealership, they will not take the car in for repairs.

    Anyone else with this problem, please contact ConsumerAffairs.com. They have taken a great interest in the problem and have an article posted on their site about it.

    http://www.consumeraffairs.com/automotive/manufacturers.htm

    They suggest Lemon Law action immediately if your car qualifies for this.
  • I own a Infinity J30t and I always use Exxon to ail her up. I used Chevron one time and I smelled that egg smell for a week, once I switched back to my old brand , all was fine
  • Someone else suggested Exxon in the past. There are very few Exxons in my area, but I'll hunt them down and give it a try.

    Thanks.

    I purchased a 2001 Nissan Xterra in November and the sulfur smell gets worse and worse. Not only does it smell of sulfur on the outside and inside, when running the heater I also get other smells. They are: electrical burn smell, burnt popcorn, exhaust and strangely enough a saltwater smell(???). The other problems that I have noticed are black soot around the tail pipe, loud popping noises from underneath while sitting in traffic(catalytic converter heating up?) and when putting the truck in drive first thing in the morning I have to sit in a neutral position for a few seconds because if I take off immediately I will peel out. I have an appointment on Friday with the dealer to check it out. Hope it's only the catalytic converter because my last SUV was a lemon. I took my Jeep(junk engineered extremely poor)in about once or twice a month in the year that I owned it for the same problems that they couldn't fix after several attempts including a recall on the fuel tank sending unit(replace two times and still broken).
  • Found a temp. cure for bad smell. Try a product called Seafoam it's been around since 1947. Go to NAPA auto parts store and ask for it.

    jukeboxcarl2: Thanks for the input. The only thing that I could get out of the dealership was to use premium grade fuel, contrary to the owners manual.
  • swschradswschrad Posts: 2,171
    I haven't had any issue in two Fords... 90 ranger 2.3L 4-banger and 00 explorer 5 L v8. I have noticed the cars I hate to follow because of sulfur stink are mostly imports. I have also heard some of the local auto mavens say this is due to rich operation because of a bad oxygen sensor in the exhaust. some sensors are iffy from day one, others get that way... when the sensor in my 4-banger got "lazy" I could start the ranger, but about the time it started to warm up, it went rich and stalled. no fun at 18 below at 2 am to be explaining things in a very loud voice to an engine. anyway, try checking the o2 sensor.
  • I took my 1998 Sentra to the dealer in my area Akron,Ohio. I thought maybe the catalitic converter was bad. I only have 2000 miles to go before the warrenty on it expires. They were of no help, said all Nissans do this and there is no cure. Then they pulled out a paper for me to read. It said gasoline is being produced with too much sulpher in it. There is some truth to this. Using BP or Amoco = Worst smell for me. It try to find gas thats not oxygenated. Any help out there?

    Post #8 (use the jump window up top) has an interesting explanation for you.

  • swschradswschrad Posts: 2,171
    like, duh, Nissan, if all the gas is sulphurated, design for it. or have your car known as a stinker by everybody in the market. I have run Citgo, Amoco, Holiday, SuperAmerica = Ashland midwest, Mobil, Cenex, and several brand-X and no-brand fuels in two Fords and a 1975 Buick with no stink. A little "rich" dusty smell on cold start is as bad as it gets. I know there have been 6 different refineries producing that product, and who knows how many down the Williams pipeline, over the years.

    it's some of the car makers, not the gas producers, who haven't got their act together on H2S.

    Well, it is almost a year since I purchased my Infiniti G20 and the sulfur smell is still existant on a daily basis. I give up!

    I discussed it with Nissan's Corporate office for a while and they refused assistance. They said that I must have bought gas at some point with a really high sulfur content and now I have to wait for it to burn off. They could give no estimate of time for when this might happen. They passed along the same pamplet to me that they give everyone that 'defines sulfur' and explains 'rotten egg odor', etc.

    This is 99% a Nissan problem and if you ever smell this at a stoplight, look around and I guarantee there will be a Nissan or Infiniti in sight.

    There are no more suggestions worth trying. I tried everything and nothing helped! I will NEVER buy a Nissan automobile again and neither will anyone I know.

    it has been suggested that flashing the engine computer will help on other brands. that sorta depends in most instances on newer control code being availiable from the manufacturer, I suspect... my experience in flashing things like half-million dollar data switches in production, all the way down to my homebrew FrankenClone computers in my bedroom, is that real-time processors can confuse their flash code on occasion and thus need a refresh for the jolly Hell of it, but load-at-boot-once machines don't usually have issues. engine computers are a real-time processing application.

    if the module dies in the flash, it was probably really No Freaking Good to begin with... but it is a nasty way to spend 600 or more dollars for a minute's worth of work.
  • Could you please elaborate on this?
    How can it help with stinky smell?
    Who can do it?
    Thanks
  • swschradswschrad Posts: 2,171
    in polite society, especially in the warranty period, a dealer uses a laptop computer to re-program the flash EEPROM memory in the main engine computer... that's "flashing" it. power shops also get into it, but that voids warranty and carries no EPA warranty protection against pollution, engine damage, etc. a really screwed up engine computer can blow the engine up, but usually a hosed box will just be a no-run situation.

    the stink from H2S gas in the exhaust is caused by dumping of excess fuel into the cylinders... it is carried out as unburned hydrocarbons, along with the additives and problems, and those react rather violently with oxygen (mostly) in the catalytic converter. sulfur from gasoline is a problem in this regard, and it catalyzes with hydrogen to make hydrogen sulfide gas. this is a pollutant, in water it's called sulfurous acid H2SO3, and emission is limited by federal law. the tailpipe sniffer should also be seeing excess unburned hydrocarbons, low CO2, and probably higher CO than permitted. eventually this excess hydrocarbon in the engine exhaust will burn up the catalytic converter... the way they make 'em nowadays, the cat "sponge" of ceramic will probably shatter from the excess heat and block the exhaust.

    none of this is good. it is incumbent on franchised dealers to honor their warranties and the 60 or 80 thousand mile EPA warranty and correct these problems. dealers will piss and moan about and try to blame things on sulfur in gasoline... and dangit, that's nonsense, it's been worse in the past, and the system is designed to deal with it, or the car would not be certified for sale in the US.

    if they can't get that together, and frankly all they need to know came in the factory base tuneup training if they bothered to send anybody to it, you may need the state pollution board and/or your lawyer to get involved. they need to sniff the tailpipe, put the car on the box, and check the flash revision on the car, and see if there are updates from the automaker's national service webserver. if so, flash it in.

    if the engine computer is sick, flashing it could kill it. so then they replace a computer under warranty, ain't nothing evil about that, either.

    this is assuming that everything works as the computer tells it to do, which puts the onus for the problem on the computer telling it wrong. any way you put raw gas into the exhaust stream... stuck injector, bad plug, wire, coil, or output transistor from the computer preventing cylinders from firing... also can cause the same result. so that's why you need to wire the car up all the way, run it per the EPA long test, compare the results to the handy-dandy tree of findings in the service manual, and thus determine all the likely faults and fix 'em in order until the problem is gone.

    what has been happening is... it runs, they got things to do, they didn't look at your problem as the factory service books said to, and you are driving an illegal car. they need to deal with it according to the books. maybe they need to finally sit down and read those books, but if you can't get their attention, get an advocate (aka lawyer or pollution bureaucrat) to remind them they are supposed to do more than count the money at the end of the day over there.

    if I seem a little torqued, well, I don't like sitting behind those stinkers, illegally firing up my asthma. I want them all fixed or replaced, now. barring that, I want the guys who DON'T fix them in the can, and the Federal pollution laws allow for that.
  • Thanks a bunch.
    There seem to be a stinking problem with new (2003) Toyota Corolla and other ULEV Toyotas.

    My Cololla stinks only occasionally (heavy accleration) so I am not sure how aggresively to pursue this. The Toyota officially denies the problem and steers people to low sulfur gas (some premiums).
