    My wife just experienced the same problem this evening. I'm taking it to the dealer tomorrow to have it serviced.

    Check engine light came on - accelerated, however, it only made the vehicle "lug" down and coast home. Took it to dealer and they found 7 error codes - parts ordered and will be here in 4 days! Told it was fine and safe to drive - drove less than 10 minutes and had to be towed to dealership.

    My Veracruz has been demonstrating similar problems.  When at a stop light the idle has irregular RPM's.   Today the check engine light suddenly came on and then the car would not go past 25 MPH.  I had the peddle all of the way down and it had little power.  I barley made it home.


    The car has less then 11 thousand miles and I have only had it for 15 months. This is not normal.

    I have a 2007 Veracruz, for the second time it appears that the module controlling the acceleration of the car has failed. The first time occurred after 10 months of service. It now appears that the same event has occurred after another 10 months os service. Each time instantaneously you loose acceleration. The vehicle continues to run, but there is only enough power to coast at about 20 mph. You have no ability to accelerate. This is a horrible feeling when it occurs, as it has now done twice, in the middle of heavy traffic with cars whipping past you.



    The Veracruz was towed in last night (Saturday), so I won't know for sure the feedback from service until Monday. I could not even reach anyone at Hyundai to complain about this servious safety problem.

    Yes, I had the same problem when my Veracruz was just 10 months old as well. I'm a Realtor and unfortunately had clients in my car when it broker down and had to be towed, leaving them with no ride back home. It was very embarassing and I was furious to have a new car break down on me. They claimed to fix it only for me to drive away and have to turn around, bring it back for the same condition. So far, 8 months later, no more problems but it's nice to finally get a "real explanation" of the "limp mode" and actuator problem.

OK, folks, here's the scoop. The dealer took our Veracruz in for diagnostic testing and determined the cause of the problem was the actuator for the Electronic Transmission Control system (ETC).

Apparently, in later model cars like the Veracruz, a computer controls the transmission as well as the engine for optimum performance.

If the computer detects a severe enough fault in one of the components of the ETC (e.g. bad sensor, bad component, etc), it places the vehicle in limp home mode.

Based on my experiences, when in limp home mode, the transmission is forced to stay in 3rd gear, the engine will not exceed 2000RPM, the accelerator is not responsive past 2000RPM, and the engine runs rough (probably because the mixture is changed to very rich). The philosophy here, as was explained to me by somebody who works for Hyundai, is to allow the vehicle to continue operating long enough so that it can be driven to a safe location or for service.

I asked whether or not this limp home "feature" could be disabled at the dealership, but apparently it cannot.

I have alerted some folks at Hyundai Motor USA to this thread so they can do further research if the problem begins to affect more individuals than just us three.

FYI - I am in no way shape or form a mechanic or mechanically-minded, so if I have explained anything correctly, I will gladly accept further corrections/explanations from an expert or mechanic. :)

    I was advised (by my cousin, an Audi mechanic) to try disconnecting the battery for about a minute, then reconnect. The light was gone, and I've had no issues since. He'd explained to me that it could be just an error on the computer, but if the light comes back, get it checked. I had started my suv without letting it warm up, and that's what had caused the error in my case. Tip: make sure you don't leave your keys in the cab when you do this. They might get locked in there when the battery resets. :)

MY Hyundai Veracruz engine (3.8L) idle too low (600 Rpm) in cold weather (less than 40F), when engine is warm and transmission on drive and vehicule stop. This cause a undesirable vibration. When outside...


It may be no engine thermostat which keeps the engine temperature at a constant 180F usually. Or you have some bad connections to a temperature sensor that sends temperature information to the Ecu (brain) and controls fuel. Corrosion causes
bad connections If you have an auto parts store scan your error codes that will be a better diagnostic. It is possible a problem with transmission fluid level or quality of fluid.

Idle fluctuating rpm check engine light


run the fault codes as the engine idle is being affected by a faulty sensor . The vibrations are probably because the idle rpm's are too low.

Oil light comes on when braking


Your oil pump is failing.... when your engine rpm drops (when stopping) the pump and engine rpm drop to idle..(light comes on). when you accelerate (rpm's increase) the pumps start working harder and the light goes off.... I am TRULY surprised the dealer(who did you see at the dealer???) did not know this,... THIS IS BASIC STUFF!! ... I mean 090 level mechanics...

Get the oil pump replaced immediately!!!!

My 2007 veracruz has a shudder when starting in 1st gear and when shifting into second. Also have a pulsating in 5th and 6th gear at 1400/1500 rpm.Seems like the car is lugging in 5th/6th gear. Could this...


Mine had a *bad*, but intermitent engine shudder (like it was running out of gas) between 30 and 40 mph. After 3 trips to the dealer, it finally did it in front of them. It's quite dramatic, so they admitted that I wasn't just bringing it in for fun and started guessing what was wrong. They found a TSB that recommended starting with one of the O2 sensors, which fixed it perfectly, immediately.

Sounds like yours isn't your engine - but I thought I should say something just in case.

Hesitation on acceleration engine runs fine otherwise


My 99 Audi A4 2.8 Quattro was havinga problem starting at times. It would idle poor upon start and then it would come up in rpm where it should be. I had hesitation from a start and after coasting for more than 5-8 seconds, the car would shake violently upon acceleration at about 1/3 throttle. I cleaned the Mass Air Flow Sensor. This helped but did not solve all my problems. I then replaced the Mass Air Flor Sensor. Little to no change there ($108.00). Lastly, I replaced the spark plugs. I bought Bosch plugs ($4.82 ea.). This got rid of all the symptoms. I had bad lugs and possibily a dirty MAF!
