Hyundai Elantra Cooling System Problem

jogo26jogo26 Posts: 1
When My car warms uo to normal running temperature, steam comes out from the top of the radiator housing across from the cap. The steam appears to be comming from around the front of the grill, and out of a space about 3 inches long. The car does not appear to be overheating, and the Guage is reading normal! Any Ideas?

    Bad hose? Bad radiator? This isn't the sort of thing you should put off doing something about.

    i had the same problem, you need to have your thermastat checked. mine broke causing the radiator to crack. broke the water pump and damaged the engine. I was told it will cost me about $3000.00 to cover the repairs. I was thinking could this be a defect in the function of the Gauge reading normal when the engine is really overheating? My car has 84,000 miles, i was told because it is the thermastat that caused the problem, it is not covered under the warranty. If anyone has any information that will help me educate myself, to deal with the dealership in regards to my engine warranty I would greatly appreciate your help. The car is a 2003.

    What good is the Hyundai 7 year/100,000 warranty if you are not covered for this? Have you tried another dealer.
  • nthenthe Posts: 414
    well, the powertrain warranty (10 yr, 100k miles) may not cover the thermostat.
  • mom47mom47 Posts: 2
    if there is a gauge failure, how would you know that your car was overheating? Would the gauge be part of the power train warranty?
  • caazcaaz Posts: 209
    guages are not part of the powertrain......Engine, which is pistons, valves.etc. and transmission are the powertrain. Now, how old is ur hyundai? could still be part of the bumper to bumper warranty.

    p.s. mom47 call a few dealers and of them may say its covered and if so...use them, but get it in writing first.

    Yesterday My Radiator cracked at 61,1416 miles just 1416 miles outside my warranty. I have already replaced my thermostat at approx 54,000 miles and now I will have to do it again since it continues to overheat, I have to take it back tomorrow I barely went 3 miles before it overheated and they swore they took it for a roadtest. I wish there was something we could do as a nation who has this continual problem apparently we are not the only ones who suffer. I dont trust it outside the city limits now cant take it on roadtrips.

    It appears you had the work done by someone else ("took it for a roadtest"). Hyundai dealers (and many other shops) guarantee their work, and there's a 1 year, 12,000 mile warranty on OEM parts they use. So if the part(s) they installed failed right away, take it back and demand they fix it for free.
  • My 2005 Elantra just died! The radiator overheated, broke a hose and blew up the engine! I heard the same thing happened to someone else I know. Both cars had 70k miles on them! Is this a widespread problem? No engine light appeared to alert me to the problem. Just had the oil changed and everything else checked in late July. I'm wondering if this is a defect that hasn't been fully reported.
  • I bought my Elantra brand new back in '03. Regular maintenance has been performed by my own mechanic since the dealer is more expensive. I took the car to the dealer to get the clock fixed and they informed me that I need to replace the thermostat. They asked me for my maintenance records which I handed over no problem. They then told me that due to the fact that I did not have a coolant flush performed at 24,000 miles, the warranty would not cover the repair for the thermostat. I held off on having the thermostat fixed because I did not have the $. Just this past weekend the car broke down had to be towed and the dealer is telling me that I need to replace the head gasket and thermostat. Because I did not have the thermostat replaced originally the warranty will not cover these repairs either. Does this sound right? Also would not having a coolant flush performed at 24K really cause the thermostat to need to be replaced and cause the domino effect where now the head gasket needs to be replaced also? My owner's manual and maintenance log book as well as the maintenance schedule on all say a coolant flush doesn't need to be performed until 30K. Any advice? Also, the dealer is telling me that to replace the 2 items it will cost me $980 but I keep reading that a head gasket normally costs a few thousand dollars! If that is the case why is the dealer only charging me $980. Not complaining about that just curious. Maybe they aren't telling me the truth. Any one with any ideas on how to handle this situation? Right now the car is just sitting at the dealer waiting for me to figure out what to do with it. Money is very tight and even $980 is out of my reach.
  • Hi! My 2005 Elantra was just donated to a charity today! As stated earlier, the car died as a result of a clamp on the radiator hose which failed. The radiator hose caused the radiator to lose all of its coolant and ultimately, the engine died. The repair estimate turned out to be $6400 and the mechanic blamed us for not stopping sooner to check the overheated engine. We did not notice whether or not the car was overheating, it was driving fine and after being parked for a few minutes, it wouldn't turn over. End of story. No smoking engine, no lights went on, nothing. The Hyundai company would not cover any costs because they claim the problem was the clamp, not the motor or the radiator! I have one other person I know who had the exact problem with their car. If I find anyone else, I will contact a lawyer to look into the possibility of filing a class action suit. It's too coincidental that both of these 2005 vehicles had the exact problem and are now worthless. I also plan to file a complaint with the States Attorney office in my state. In addition, I will do everything in my power to tell everyone I know to NEVER BUY A HYUNDAI because their warranty is as worthless as their cars.

    Sorry you had this problem. But the cause of your problem is stated as two different reasons in your posts #10 & #12.

    Belts, hoses and clamps do break, as you painfully found out and can happen with any make of car.

    We did not notice whether or not the car was overheating, it was driving fine and after being parked for a few minutes, it wouldn't turn over.

    The fact that you did not notice that the engine was running higher than normal and becoming dangerously hot, unfortunately, was your fault not the car's. The fact that there was no smoke only means there was no fire. It was super heated metal (cylinders and block) that caused the engine to seize.

    Again, sorry for your misfortune, but there is no easy way to say the problem was of your doing and not a defect of the car.
  • My car is a 2003, but I feel even more horrible for you since yours was newer! My car also had a coolant leak, when you opened the hood you could see the fluid all over. I had the radiator hoses and clamps replaced also. The problem had been going on for some time, judging by the way the fluid had dried all over the place in there. I don't tend to look under the hood often unless I am checking my fluid levels. Hyundai is putting me at fault saying that my current problem is due to a faulty thermostat that they had told me needed to be replaced a few months ago. I admit my part that I should have replaced the thermostat, but who ever heard of a car with less than 40k needing this done? If you ever do file a class action suit let me know on this board. Good luck!

    Umm.... YOU did, when your mechanic TOLD YOU about it. I mean.... DUH! If a thermostat fails, you don't wait MONTHS to fix it!

    And replacing a thermostat at 40k is not unheard of. It doesn't happen a lot, but once it a while it does. If I were the dealer I wouldn't fix your engine under warranty either.

    I know of several people that have had major work done under Hyundai's warranty. The difference between them and you is they took proper care of their cars.
  • Being that I already said in my original post that I admit that I was wrong in not replacing the thermostat, I don't feel it was necessary for you to make a comment like that. You don't know my situation but I wish you did you would take your snobby comment back in a heartbeat. Besides, my previous mechanic (who I now no longer go to because of this) had told me that I did not need a thermostat and therefore would be wasting money that I don't have. I do maintain my car this just had caught me at a bad time. Please don't make comments to a person like that unless you know their whole situation. Like I said I already admit my wrongdoing.

    So what do you want from Hyundai? I mean, you say, "Hyundai is putting me at fault", as if it's not your fault.
  • my question (and purpose for posting in the first place) was is it common for these problems to happen on a car with low mileage, carefully driven and garaged and maintained on a regular basis? Contrary to what you believe, I do maintain the car regularly. I just don't take the car to Hyundai for it. My mechanic at the time advised me that there was nothing wrong with the thermostat and told me to save the money for my son who is very sick. Helpful, maybe even friendly answers are is all I am asking for. Thank you
  • backybacky Twin CitiesPosts: 18,910
    Yes, it is not uncommon for a thermostat to fail at around 40k. That happened most recently for me on the last Honda Civic I owned. It doesn't matter if the car was garaged (as mine are), has low miles (as mine do), are carefully driven (as mine are), and are maintained on a regular basis (as mine are). If a part is going to fail, none of that will matter.

    Since your mechanic advised you that there was nothing wrong with the thermostat after your Hyundai dealer advised you to replace it (I thought that is what you said?), have you asked the mechanic if he/she would be willing to cover the cost of the repair?

    To my knowledge, a thermostat replacement is not an expensive repair. Sometimes it is the best policy to pay a little now vs. (potentially) a lot later. Another example is timing belts. The replacement can be fairly expensive, a few hundred dollars if done at a dealer. But if it breaks, the engine can be ruined. So holding off on replacing it can save money now, and maybe it won't break. But if it does... bad news.

    This may not be the kind of answer you are looking for, but it's the best answer I have based on my 35 years of owning cars.
  • doohickiedoohickie Posts: 949
    So your mechanic basically told you what you wanted to hear instead of what you needed to hear, it sounds like. That kinda sucks.
  • Am I missing something here,? IF there is/was a thermostat problem would it not be advisable to replace it as soon as possible? I don't know the price of such a repair, but certainly it can't be too much. IF the problem is hoses, and or clamps giving away, these too are unpredictable and shouldn't be exorbitant either. Regardless, it is obvious that they need to be repaired so as not to lose the engine or have any major problems. I wouldn't begin to guess about the warranty coverage however. :confuse:
  • doohickiedoohickie Posts: 949
    If a wear item breaks that causes other damage, Hyundai generally won't cover it under warranty, although it's worth it to try several dealers. I base that on brake problems that they try to blame on bad pads or shoes causing the calipers to go bad (when I think sometimes it's the other way around). Is a thermostat a wear item? I'm not sure. But if it was diagnosed as bad, then wasn't replaced and a major engine problem results, you can hardly blame Hyundai for the major engine failure.
  • This is the kind of thing that concerns me. While it's not unheard of for a thermostat to fail to open and overheat an engine at 40k or so miles, it is certainly not common. Most concerning, though, is hearing that lights weren't coming on before the engine internals were damaged. Every time I've had a car overheat, it was obvious on the gauges.

    Frankly, I'd raise holy heck and try to get them to put a crate engine in my car, at least about leaking hoses or faulty clamps. It isn't fair for Hyundai (or any other automaker) to dwell long and loud about their fantastic warranty and then be so brutal in their expectations of average car owners. Their warranty is worthless to me if I have to crawl all around my car and constantly inspect it every time I think about driving it to make sure a hose hasn't failed, all so that my warranty will be honored.

    FWIW, if it overheats severely within the B2B warranty, through no fault of my own, I'm likely to *ensure* that the engine seizes. Just because it will still turn over and run doesn't mean that Hyundai's faulty hose/clamp hasn't galled or scored a main bearing that will now fail prematurely. I paid for this warranty. I'm willing to do my part to realize the full potential for reliability from my Elantra. In return, I want a mechanically flawless car from Hyundai.
  • Thank you for your comments. You're the first person to reply who at least understands my frustration!
  • backybacky Twin CitiesPosts: 18,910
    Every time I've had a car overheat, it was obvious on the gauges.

    Same for me. The Elantra has a temperature gauge. When the engine started to overheat, the needle on the gauge should have moved up close to and then into the red zone before the hose blew. If not, then perhaps the gauge is faulty (was it checked out after the hose blew?) and that could be a good reason to demand that Hyundai cover the engine repair.

    Is there someone besides the dealerships that we can talk to?
  • doohickiedoohickie Posts: 949
    Yes. There are owner-contact numbers to call in your owners manual.

    Aftter running well for a half hour or so the air conditioning runs warm. It will come back on for several minutes and then run warm again. This continues a couple of times more with shorter cooling periods until it runs warm continuously. Can anyone help me with this problem?????? thanks. durantp

    When was the last time you had it recharged?
  • menzy3045menzy3045 Posts: 1
    That happens to me as well. I haven't had it checked but I was assuming it was the coolant.

    Also, this must be a problem with all elantra's but my car just broke down as well without any warning, no engine light or any indication from the temperature guage. Turns out my radiator was cracked and leaking coolant all over the place. This was without warning starting a 90 min car ride. Luckily it was only my radiator and no gaskets were blown.

    My 2003 Elantra has about 90k miles on it and it sounds like this problem is common. No mechanic mentioned my thermometer as the problem. Is this an expensive fix?
  • Does the 2012 Hyundai Elantra use extended life antifreeze?
