6 Engine Exhaust System problem of the 2012 Hyundai Elantra

Failure Date: 09/11/2015

Highly frustrating and potentially life threatening situation Hyundai has put me in. On September 11th my vehicle caught on fire in the rear by the exhaust pipe. Prior to this my vehicle had been at rick case Hyundai 3 times with me complaining the transmission was not working properly the 1st time I was told there are no codes so we have to wait till it breaks, the 2nd time I was told no codes sorry, and the third time they actually replaced a broken part that controls the shift times in the transmission. Could show them my problem. I asked Hyundai corporate to do an investigation into the transmission and the fire and help me resolve this issue. They went through their 6 week process and then denied my claim saying it wasn't found to be a malfunction of any parts that caused the fire. I have video of where the fire started, the transmission not working, and countless pictures that show the fire obviously started at the tailpipe due to an increase in temperature because of the transmission failure. When I ask Hyundai for the information that lead to their conclusion they say it's confidential and proprietary and will not let me see it. When I tell them the transmission is still not working and everytime I drive it there is a burning smell and I'm scared for my safety and life driving this car they just say Hyundais decision is final and they won't honor my warranty on the car. They claim it's perfectly safe to drive and operating as intended and designed. I feel they are covering somethings up or never actually investigated this incident which is why they won't release information. During the fire malfunctions in the head shield and taillight wiring were discovered making for 4 possible life threatening defects my car was parked at work in my parking space when the smoke and fire started.

9 Engine Exhaust System problem of the 2002 Hyundai Elantra

Failure Date: 02/03/2011

I own a 2002 Hyundai Elantra. When I bought it used in 2005 it ran very quiet. A few months ago I noticed it seemed a little louder. Last week the check engine light came on so I took it to my mechanic to have a diagnostic. Found out there is a crack in the manifold. I am aware that many other 2002 Elantras have this problem, and that there was actually a recall on some of them. My car however was not included in this recall. I contacted Hyundai consumer assistance dept. And was sent to their dealership to have the car checked out after which I was told that the crack in my manifold did not match the ones that the recall covered. How ridiculous. Obviously their is a problem with all of the manifolds in these 2002 Elantras other wise they would not all be cracking. The repair is very expensive and I think it is unfair that any vehicle owner should be made to pay for the repair being told the crack is due to wear and tear.

10 Engine Exhaust System problem of the 2005 Hyundai Elantra

Failure Date: 12/10/2009

On 12/10/2009 I had taken my auto in for service at the local Hyundai dealer. I told them we were having a problem with a funny smell coming out of the dash when the car is started and it continues (the odor) while the vehicle is running. The odor is not there while vehicle is not started or running? they performed the new york state safety and emissions inspection and the vehicle passed. They then went on to explain that the odor that is coming out of the vent is a normal condition from converter and fuel winter blend ? I have owned this vehicle since day one and have never had this problem before? this is my fifth winter. I also have 2 other vehicles and we buy our gas at the same station and I am not having this problem with either one. I was told there is a service bulletin on this issue? but when I asked for a copy I was told he couldn't find it ,and when I went online I couldn't either. I don't know if you can help with this issue or not but if there is anything you can do or point me in the right direction I would appreciate it because as far as the dealer is concerned this is normal and I don't see what's normal about it . Thank you for your time.

11 Engine Exhaust System problem of the 2002 Hyundai Elantra

Failure Date: 12/15/2008

Already a recall on 2002 Hyundai Elantra, but the 2002 Elantra that I have is past the recall date of Jan. 31, 2002. My car, # was built in March 2002 so not covered on recall campaign #05-01-001-1. Crack between port #3 and #4 on the manifold. The part has been installed on the car so I expect to be reimbursed cost of part and labor to install.

12 Engine Exhaust System problem of the 2003 Hyundai Elantra

Failure Date: 11/15/2008

I purchased my car about 3 months ago. Not long after purchase, the engine line lit up. I noticed when this happened the rpm's dropped and the car would sputter. I had a mechanic look at it. He checked the car by computer and felt it needed 2 sensors. I let him replace these. 2 days after the repair the same issue began occurring again. This time, when I stopped as for a traffic light, the car would stall, all warning lights would go on, and it would take a couple of tries to start. Also, I purchased this car at arnold Hyundai in roseville, mi. They went out of business not long after I purchased the car. I took the car to another mechanic and they could find nothing wrong. I took the car to a Hyundai dealer. They thought a guide wire had come loose and repaired it. A couple days later the car was having the same problems. I took it to the dealership on December 22. They did a thorough inspection and said there is a leak in the vacuum system? also a problem with the exhaust. I'm wondering has there been a recall on this system or do have some sort of recourse?.

14 Engine Exhaust System problem of the 2003 Hyundai Elantra

Failure Date: 08/12/2005

Ever since I have bought the 2003 Hyundai Elantra new 2 years ago, I had nothing but problems. I have had serious exhaust problems, and have been to the dealer several times about this. I have been really sick, breathing in the fumes from the car. My carbon monoxide level is high, and I have been having trouble breathing for a long time now. The dealer refuses to see a problem with the car. I have had people drive in my car, and smell this exhaust. The exhaust smells like a skunk, and backs up through the front inside vents, it smells behind the car, and I cannot open the windows, because the smell is so strong it comes through the windows when opened to. The dealer keeps saying they don't smell anything. This is a very serious matter, and it amazes me that people care about money, instead of someone's health and safety.

15 Engine Exhaust System problem of the 2002 Hyundai Elantra

Failure Date: 01/01/2005

My 02 Hyundai Elantra has two bad cracks in the exhaust manifold. I know that other 02 Elantra's had a recall, and I think it should be extended to include all the bad manifolds. This is a major safety hazard because it can lead to carbon monoxide poisoning. Within a short period of time when the vehicle is stopped in traffic, or stuck in winter conditions carbon monoxide can build up inside the vehicle leading to death of the driver and passengers.

20 Engine Exhaust System problem of the 1997 Hyundai Elantra

Failure Date: 06/06/1997

Since the purchase of my car new I have had the transmission replaced three times, the pulse generator replaced twice, and the electrical wiring replaced twice because it kept buring out. I would repeatedly take my car into fairfax Hyundai for service due to slipping transmission, car cutting off and steering locking up while driving on the beltway at 65mph smoke coming out of the exhaust etc. Finally on 17 March 1999, approxiamately 4 weeks after paying 350 dollars to have my engine cleaned (recommended by service manager) my engine blew at 15 mph. Oil was spurting out everywhere and the dealership has refused to give the the Hyundai complainant line number. The customer service rep. Stated that I would have to get that number from the service manager at the dealership where I purchased the car. . The service manager tommy has refused to give me the number but states that he is willing to work out a reasonable rate for parts a labor. Granted I have 78,000 miles on a 97' however these are all highway miles 167 miles roundtrip to work. All scheduled maintanence was done. I do not think nor feel that I should have to be saddled with this lemon any longer nor should I have to pay for any repairs since the car has been going back for major engine problems since 6/97 three months after purchase.
