Hyundai Elantra Problems 2007+

  • I bought a new '09 Elantra SE. Within a week or so I have started noticing popping sounds from the rear when I make turns over bumps / ramps.
    I took it to the dealer, and they heard the same noise during the test drive and said it is from the rear window. The service center guy explained that the when going over bumps the car twists, and the window makes these kind of noises. He said the problem is normal and that it occurs even in some Toyota cars...
    He basically put some lubricant around the rear window seal, and said that it should gradually go away...

    It has been a couple of days since he put that lubricant, and I still hear the cracking sounds from the rear...

    Has anyone else come across this kind of noise/sound?

    I have driven several Elantras of the current generation, some on long trips, and none have made that kind of sound. I think your dealer is being evasive. It could be that the rear window is not seated properly. That is fixable, but would not be real easy--maybe that's why they don't want to do it. If you have another dealer or more in your area, you might want to take it to them to see what they say. Or call Hyundai Customer Service about it.

    Also, have you returned your survey yet? The dealers treat those very seriously. If you haven't filled it out yet, you might call the sales manager and explain you'd like to give them top marks on the survey, but you can't while this issue is unresolved.

    I rented one last fall and heard a similar noise--but from the sunroof, rather than the rear window area. Could this be the problem?
  • Love my '08 Elantra. BUT, for the last 8 weeks have had a loud "clunking/thunking/banging noise" from the rear undercarriage when going over bumps, turning, accelerating from stop. Noise is not consistant and may be related to the gas tank. Local dealership has been very attentive, but cannot find the source. Just got an answer on another forum that this could be the separator flap in the gas tank that has broken loose from its weld. Makes a lot of sense..., and as I post this the dealership service people are now following that lead. Anyone else had that problem and found a fix? Thanks
  • 2004 Elantra with auto trans will not start once or twice in a 2 week period or sometimes longer. I eventually get it started after trying to start it 3-6 times. I have not checked for spark but I do hear the fuel pump.

    There's a lockout switch inside the A/T shifter. The next time it won't start, try wiggling the shifter and see if you get results. If so, the problem is the neutral safety switch.
  • I have an '09 Elantra SLE that has started the same popping noise from the rear window.

    My issue seems to be worse when it is cool outside. I live on hill so I hear the loud rear window popping every time I go up my driveway.

    Did yours ever get fixed?
  • I also have had this happening in my 09 elantra. We took it to the dealer and they said they have had alot of people calling in about this problem. As soon as I told them the problem they knew exactly what it was. They said they actually have to take the back window out and put some kind of spacers in between the window and where it sits to make it stop doing that. They have the auto glass co. coming tomorrow to do a few of them so, I'm actually taking it tomorrow to have them do mine. We'll see if that solves the problem!
  • Thank you brenderz05. Let me know how it works out for you. I took my 09 Elantra into the dealer today about the window popping. I was explaining the issue to the service manager when one of the mechanics stepped up and said he owns an 09 Elantra with the same problem. He said it was driving him crazy.

    If you don't mind. Do you know if the spacer solution was a "Hyundai solution" or a clever fix by a mechanic and/or the auto glass co.?

    Thanks!
  • Hi everyone.

    We have a 2008 Hyundai Elantra.

    Today while driving at 60Mph with cruise control, stepped on the break to slow down and instead the engine revved up, the car jumped and started speeding up to 65-70Mph. It was a considerable effort to get the car stopped as the breaks did not seem to work. It also resulted in getting chased by a cop...

    After finally stopping, the shift was locked, would go only into neutral, but not into reverse or park.

    The car got towed to the dealer, and they replaced the "break switch" saying that was the reason for all the problems...

    So, can a "break switch" speed the car up, not let the car break, and lock up the shift?

    Or should we be afraid of hitting someone, next time this happens? :(

    Thanks.

  • This is exactly what has been happening to me and even at a red light my car will lurch and rev up and I have had it to the dealer 2 times and each time they tell me there is nothing wrong. I have an appt. on Monday as there has been a grinding noise for over 6 months when I turn my wheel to the right and when I put the car in park on a slight incline from day 1 of owning the car I have had it 4 times to the dealer for it making a chugging noise and the brake not catching. I am glad I am not nuts like the dealer is trying to make me feel. I think I should change to a differnet dealer and change my appt. now after reading your letter as I was told already if it is my brakes or bushings or anything it is under warranty. And at my dealer they keep telling me nothing is wrong. I have even thought my foot caught the gas pedal the same time as the brake to rev it up to lurch forward. Thank you for posting this. I think a report needs to be filed with the Saftey Dept. like when the fuel pump was recalled.
  • I just found this:

    The brake switch operates a few things. It turns the brake lights on; it disengages the cruise control; it also controls the shift lock, traction control and ABS.

    There is an open recall for the brake switch (see here and here) and that would cause your problem. If the dealer replaced the brake switch, your problem should be solved.

    The National Highway Traffic Safety Administration (NHTSA) and Hyundai have initiated recalls on 963,305 vehicles as part of four separate campaigns. The first recall, blanketing over one half million late-model vehicles, is nationwide. The other three recalls, all corrosion-related on older vehicles, are limited to the regions of the country where salt is used to de-ice roads in the winters.

    The most widespread recall, affecting up to 531,894 2005-2008 Accent, Azera, Elantra, Entourage, Santa Fe, Sonata, Tucson, and Veracruz models, is NHTSA Campaign 09V122000. It is focused on a malfunctioning stop lamp switch that may prevent brake lights from illuminating when the pedal is depressed (the same switch may also cause them to stay lit after the brakes are released).

    Manufacturer: HYUNDAI MOTOR COMPANY Mfr's Report Date: APR 14, 2009
    NHTSA CAMPAIGN ID Number: 09V122000
    PE09003

    NHTSA Action Number: PE09003

    Component: SERVICE BRAKES, HYDRAULIC:SWITCHES:BRAKE LIGHT
    Potential Number of Units Affected: 531894

    Summary:
    HYUNDAI IS RECALLING 531,894 MY 2006-2007 ACCENT, ENTOURAGE, SONATA, MY 2007 AZERA, ELANTRA AND SANTA FE, MY 2005-2007 TUCSON AND MY 2007-2008 VERACRUZ VEHICLES. THE STOP LAMP SWITCH IN THE AFFECTED VEHICLES MAY MALFUNCTION. A MALFUNCTIONING STOP LAMP SWITCH MAY CAUSE THE BRAKE LIGHTS TO NOT ILLUMINATE WHEN THE BRAKE PEDAL IS DEPRESSED OR MAY CAUSE THE BRAKE LIGHTS TO REMAIN ILLUMINATED WHEN THE BRAKE PEDAL IS RELEASED. A STOP LAMP SWITCH MALFUNCTION MAY AFFECT THE OPERATION OF THE BRAKE-TRANSMISSION SHIFT INTERLOCK FEATURE SO THE TRANSMISSION SHIFTER WOULD NOT BE ABLE TO BE SHIFTED OUT OF PARK POSITION. IT MAY ALSO CAUSE THE ELECTRONIC STABILITY CONTROL (ESC) MALFUNCTION LIGHT TO ILLUMINATE, AND IT MAY NOT DEACTIVATE THE CRUISE CONTROL WHEN THE BRAKE PEDAL IS DEPRESSED.

    Consequence:
    THESE MALFUNCTIONS MY LEAD TO A CRASH.

    Remedy:
    DEALERS WILL REPLACE THE STOP LAMP SWITCH FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING APRIL 2009. OWNERS MAY CONTACT HYUNDAI CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.

    Notes:
    HYUNDAI RECALL NO. 092. OWNERS MAY ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S VEHICLE SAFETY HOTLINE AT 1-888-327-4236 (TTY 1-800-424-9153), OR GO TO HTTP://WWW.SAFERCAR.GOV .
  • Thank you. I am going to print out the recall and shove it in their face as they have known since 8/2008 how many trips I have made to them over my problem and they keep on telling me there is nothing wrong. I have an appt for Tuesday and this time they had better fix my problem.
  • The manual transmission just went out on my son's 07'. This falls under factory warranty and Hyundai is going to fix. Problem is, this transmission is on "national backorder". On-line research finds problems with automatic transmissions, but not manual. Why such a backorder? Anybody else hearing or experiencing the same trans problems?
    Anybody have knowledge, that if we make a big enough stink we can get a loaner car? (son needs to return to college 1 week)

    I just experienced the same thing the other day.I was on a highway and it was real windy, and every few minutes i would hear this beep. I have no idea where it was coming from
  • backybacky Twin CitiesPosts: 18,732
    I can only guess the backorder is because there aren't many 2007 Elantras in the US with a stick shift, so supply of complete manual transmissions is low. Also, sticks are pretty reliable, so HMA probably doesn't keep many in stock.

    If I were you, I would press (politely) for a loaner car while you are waiting for the transmission. Mention your hardship (son needs to return to college) that was caused by Hyundai's inability to fix the car promptly. If your dealer is at all interested in maintaining customer loyalty and satisfaction, they'll provide a loaner or pay for a rental.
  • Thanks for the suggestion. We have contacted the dealer, they refuse to provide a rental car. All good though, the replacement transmission is due early next week. Bad Hyundai Fresno California Do not buy your Hyundai from them!

    My 2007 Hyundai Elantra speedometer reads 10% higher than the actual speed. I have tested this using a stationary radar speed display and by using friends in other vehicles. Do you know the fix?
  • mcphunkmcphunk Posts: 1
    This happens to my 2009 Hyundai Elantra too.
    It's driving me nuts, how do I make it stop?
    Is there a recall or something?
    Everytime I go over a bump or turn into my driveway it pops from the rear window area.
  • yol101yol101 Posts: 1
    my 2007 elantra has strong vibration under the hood when I accelerate slowly to 35-40 miles/hour. I took it to the dealer 2 times and they say they can't find the problem.
    It only happens when I put the gear to "D", I tried to put the gear to "3" or other settings and no vibration at 35-40mph.
    Does any experience this vibration?

    I went to the dealer a few times on that; and they finally figured that it is coming from the rear window... They applied some kind of a lubricant between the window sealing. It still persisted after that.
    I took it back to them, and they convinced me that it would go away after sometime; and re-applied the lubricant.
    At that time they also said that if it still doesn't go away; the next time I come they would call the 'Glass repair' folks and have the rear window removed and resealed.

    Anyways, long story short, the noise went away after a couple of days just with the lubricant...didn't have to go back for the glass work. It has been 4-5 months now, and I don't get that noise anymore.

    Unfortunately, changing the break switch didn't help. It fixed the immediate problem with the messed up transmission, after the cop chase, but after several months, we still experience random speed-ups when breaking. After not being able to stop for a few times, and coming away from the dealer ship with "no problems found" and after we couldn't stop at a red light last time for the same reason again, we initiated the lemon law proceedings... It is really scary to drive a car, that we don't know if it would stop or actually speed up when we push the break. We will see where that leads...

    We have had this same problem with our 09 Elantra. It was happening quite frequently when we first bought the car in July 09. As usual when we took it to the dealer it did not happen for them. However, it seemed to go away during the winter months but, has now returned since the weather has warmed up here in Ohio. Any additional help or thoughts on this topic. Seems like the same problem you were having. It seems to happen more frequently when are making sharp turns, turning to and when we start to go up a grade or as of now sometimes when we go over bumps.

    I have the same problem with my Limited Edition 08. I figured out that this noise is coming from trunk. I lubricate the hinges and the rubber buffer and seems like the noise is gone. Looks like over the time hinges got dry and star making cracking sound.

    My 2007 Hyundai Elantra has lost power three times in the past 2 weeks as I have been breaking to come to a stop at a red light. Each time it has happened, the engine has been relatively cool. It has happened within a few blocks of work after the car has been parked all day. After it rolls to a stop, all the dashboard lights flash on and then off. I have been able to restart the car each time after turning off the ignition and have then been able to drive it home (about 10 miles) without any further issues.

    I have taken it to two different Hyundai dealerships and neither service department has been able to replicate the problem or find any stored codes that would indicate what the issue is. I am still under warranty, but they tell me they can't do anything for me at this point. The first service rep simply told me to keep the Hyundai Roadside Assistance number handy. The second rep told me to try fueling it with a higher octane grade.

    I am extremely frustrated and I am anxious about driving it. Does anyone have any suggestions???

    1. Have your battery tested. Check the alternator output while you're at it. With the lights flickering I'd suspect the electrical system.
    2. Check/change any filters you can. Air filter, etc. If not electrical, then maybe it isn't getting the air or fuel it needs.
    3. Agree with burning a few tanks of premium. It's possible you got some bad gas.
    4. They shouldn't need changing but check/clean the spark plugs.

    I truly thank you for your reply. I will work down your list.

    Hello Everyone,
    We are looking for people who have the same problem as we do with our 2008 Hyundai Elantra.
    We had several occasions since last summer (2009) where when stepping on the brake instead of slowing down the engine revved up and the car started speeding without touching the gas pedal. We have the cruse control on when driving, however it is not always set. …For instance we were getting chased by an officer as the car would not slow down when stepping on the brake in a limited speed zone…or lurching forward in a parking lot as we wanted to come to the final stop, causing the car running into the 4 lane traffic through the bushes and the side walk. The car has been back to the dealership 5 times and since they cannot duplicate the problem they say there is no problem existing. They are implying that we cannot drive, and that we are maybe lying about it to take advantage of the manufacturer.
    We had arbitration, and since at the time of the arbitration test drive the problem did not occur, they decided that the car is not dangerous to drive, and the problem does not exist. They implied their solution of trading in the car and get a new one. The car is a road hazard it can cause a deadly accident at any time, and since the problem occurs randomly it cannot be avoided really. How could we possibly trade it in and sleep well at night knowing that maybe someone else will be hurt just because we passed over our problem. Just because we would not own the car that does not mean that the problem is solved. We are in shock to see that certain individuals value money more then human life.
    We are going to go further with this issue to another arbitration and trying to find people who have the same problem.
    Online, we have found a lot of complaints about the same type/model of car and same issue; we will pursue to find those people as well. Your help would be greatly appreciated. We have to do something together for public safety before something tragic happens.....
    Thank you very much for your time...We are looking forward hearing from you.
  • I would like to know more information in regards to your post about the elantra
    On monday my car was totalled due the car not stopping when the brake was applied. It felt to that the car sped up when i applied my brake there was no stopping it. At the time i was pulling into a parking spot at the local cvs and hit a structure @ this point there is over $9000.00 in damanages and wait for insurance company to investigate.
    I would really appreciate any info you could forward me and i would gladly help you with any info i receive at this point its trying to prove the defect in the brakes

    Thank you
    Therese

    Make sure you get your car checked by a respectable independent service and get everything documented. Hyundai will deny that anything was wrong with the car, and will blame the accident on you.

    Or at least this is what my lawyer told me, for the next time when the car speeds up again while breaking...

    We got denied on arbitration, and I was told that we will always be, as long as we take our car only to Hyundai's service because they get rid of anything proof even if they find something...

    I'm not saying they would not try to fix the car, but they will do everything in their power to make sure nothing comes out... Imagine a Toyota type bad publicity for them... They don't want that, so they will deny and deny...
