Hyundai Santa Fe Engine Problems


Hoping someone may help me with this.

My SUV has had hesitation at about 45mph. Today, @45mph my car starting lurching & check engine light came on. As I slowed down, the lurching stopped and the light went out. I parked my car & will have it towed to the shop in the morning. Any idea, is this something major? It has 104000 miles on it.

Thanks for all your help!

    did it ever shut off on you?
  • No. I was in traffic, going from 60 down to 45. Once it went below 45, I would step on the gas and it felt like it wasn't going to go any faster and it was starting to "shake" I stayed below 40 for about a mile(lots of road construction) before I was able to pull off.

    I'm just hoping it's nothing too major.
  • It is speculated that the Santa Fe base engine will be the 2.4 liter Theta II which has estimated horsepower of 175-180 plus hp

    should the 2.7 liter V6 be replaced by this engine Yes or no?

    The 2.4 in my opinion has great advantages like timing chain, plus better fuel economy, easier to maintain.

    I think Hyundai should.

    Here is what I would like to see:

    Fact: the next coupe will have 2.0L turbo four (rumored around 223hp) and 3.8L V6 (300hp+) (2.7L V6 removed)

    Speculation: the Tuscon redesign should come with 4 cylinder only (2.7L V6 removed)

    Speculation: I know Santa Fe's 2.7L V6 is there mainly to keep the price low but I think Hyundai should offer only the 3.3L V6 on the SF.

    they could go to an 8cyl too! and have a 4x4 optional driveline with the 8...

    300hp is nice on the 6 tho'!

    Not a chance, at least in the crossover lineup. If anything, it would be Veracruz, but the diesel variant is coming over to the North American market in a few years.

    I can see the coupe with V8 but why when the V6 produces upwards in the 300hp range. Hyundai could, however, with 400hp output in the coupe :-)

    The Santa Fe needs a diesel. I understand that the Elantra and Sonata will get a diesel option for '09 or '10. Why not the Santa Fe?
  • the rav4 has a 4 cylinder why can't the santa fe, which are competitors.
  • The shop changed the plugs and filter. So far works great!
  • somedai1somedai1 Posts: 416
    yeah - 4cyl engines really react badly even if only 1 plug goes bad...
  • The Elantra and Sonata are getting diesels in '09/'10? It's expensive to have a diesel engine that passes emissions (around $5000), and both the Elantra and Sonata already get good mileage. EPA rates Sonata as the best mileage Large car and the Elantra gets 25/33 mileage, the best in its class for a non-hybrid. Adding a diesel to a larger SUV makes sense, but for these? Not so much! :D

    In the AM when I start the engine immediately revs to 2000 rpm and stays there for at least 15-20 secs. ( I can just feell the metal on metal inside the motor). It slowly falls back to a fast idle as the motor begins to warm up. My dealer just says "they all do that" and there's no way to adjust so just forget about it. Since a lot of wear can happen during this start up period does anyone have any comments on their experience on start up. (Lucas additive?) Thanks

    it is typical for a car to rev high and then settle to its normal rpm with no action from the driver. whether or not that is too high - i'm not sure... but it seems normal. if it does not settle back to it's normal rpm then there is a problem or if it stays high for an extended period of time. if you actually feel grinding then there is a problem. if you are just concerned for the wear of your engine - i would suggest using synthetic oil all the time - possibly royal purple. Lucas is good but it may not be necessary. Hyundai says not to use additives. oil companies say their oils have all the additives they need already in the oil. if friction concerns you you can try all the different advertised stuff to see what works for you. if you have that ticking noise in your engine CD2 helps but it will not repair any major problem.

    My service dept just told me the clacking sound when accelerating when the engine is cold is likely "piston slap" - very rare but occurs. They said they may need to rebuild the engine or replace the engine. The SF is just under 2 years old and 24k kms. I really don't want a "new" rebuilt vehicle, even the new engine makes me nervous. Any advice or thoughts on how I should be handling this?

    Did this get handled to your satisfaction? I just bought a Limited with the 3.3L

    My 2004 Santa Fe made a noice and then just stopped. I got a 04 Santa Fe with 3.5 L the water pump locked up going down the road. It never overheated. the Auto repair shop also replaced the timing belt. The mechanics told me that the engine would have to be replaced after they started it up. I think that they might have gotten the timing belt off a tooth. Like I said earlier the vehicle never overheated it stayed just around 210 degrees never did smoke. The timing belt wasn't that bad just frayed on the edeges. The engine has only 51k miles & frequent lof's. I am not sure if I trust this mechanics dianosis . He first said the engine seized and then when a mechanic friend talked to him the auto repair mechanic said it started but it made a noise and he shut it off quick. The said this was a common problem with 2004 engines. i been trying to look it up on internet and i do not see that this is a comon problem (I am I wrong). I think something fishy. The story keeps changing and I said i was taking it to another mechanic. They only charge me for the cost of the parts but did not finish the job (did not hook up the altenator or wires) and I afraid to take it out of the shop and blame it on the next shop (who happens to be owned by a friend of a friend). What do you think or know about known problems with 2004 Santa Fe engines or could youmake any suggestion how to handle this problem?
