Good afternoon, I am contacting the Consumer Affairs department regarding the recall 180 Hyundai is conducting a safety recall in the United States to confirm the high pressure fuel pipe was properly connected by Hyundai dealers to the high-pressure fuel pump outlet when the engine was replaced under recalls 132 and 162. In come cases, during the engine replacements under recall campaigns 132 and 162, the high pressure fuel pipe may have damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak from the pipe. Hyundai will notify owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's recall number for this recall is 180. My Hyundai Sonata limited was involved in an accident after Hyundai had just replaced the motor and on impact the whole car caught on fire, so what I am trying to do is find out do I need to contact NHTSA in regards to this matter but I feel that my life, the person involved in the accident was totally at risk due to this malfunction and I am out of so much and was put in a very hard financial place due to this fire when it could have been prevented. If someone could please contact me at [xxx] thanks, [xxx] VIN #: [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I never received information regarding the recalls on my Hyundai Sonata 2011 vehicle. I was driving my Hyundai Sonata 2011 on 4/11/19, going about 60 miles an hour and the cut shut off. Was in heavy congested traffic and I was almost rear ended with no control of the Hyundai Sonata 2011vehicle. My Hyundai Sonata 2011 was moved to the side of the road where a tow truck was called. Subsequently, Hyundai Sonata 2011was taken to the huntington dealership. Dealer informed me there was 7 recalls of which I not aware of in regards Hyundai Sonata 2011 this could have been a life threaten situation and Hyundai should notified me of all recalls. This is unacceptable and life threating to family friends and community.

My car had a engine recall. However, the recall was only extended to 10 years of the date and to 120,000 miles on the car. I bought the car with 115,000 miles on the car from bayway Lincoln and did not receive any paperwork detailing about the engine recall. I typed in my car in VIN and a recall came up for the past, but my car is not valid anymore. Hyundai says that will not fix the recall because its pass 120,000 miles. If I never received any paperwork in the mail from Hyundai detailing about the recall how would I have known to get it fixed. I was not informed about this recall and two other recalls. Now, I have to either buy a brand-new engine or get a new car because I was not informed of the recall and now Hyundai refuses to hold up their end. I should have been informed of this by Hyundai.

  • 100,000 miles
After I had my engine replaced pursuant to the recall in 2017. Prior to 2017 I never had a problem with my car. Once they put the new engine in my check engine light came on, they replaced 4 different parts at different times and still my check engine light came on. They found that there was a small area in my harness wire that a mouse had damaged. I dropped my car off in October 2018 to have the front and back wire harnesses replaced. Since that time Hyundai cannot get the wire harnesses delivered to fix my car. I have been without my car for five months now and had no idea when they will receive the wire harnesses. I have to drive an elantra without lumbar support for the last five months, which has caused me back pain since I have had 6 back surgeries. Additionally my car has not been able to be registered since 2017 since it will not pass smog with the check engine light on.

All service records indicate that MY2011 Sonata has been well maintained to the extent that I am getting offers from the dealership that it is needed for parts. While on the way home from a purchase offer event on Saturday 3/23/19 after exiting the highway to a major thoroughfare by a busy mall the engine completely shut off. Luckily I had just pulled into a turning lane. Police had to come to stop traffic and push car off the road.

2011 Hyundai Sonata gls automatic transmission. Problem with ignition key. The key will not go past acc to the lock position to allow the key to be removed. Followed directions in manual to push the key in at acc position, but the lock mechanism does not move. Happens every other day. Have restart the car and move it and try the process again to get key to move into its proper position (lock) to remove key. Impossible security situation as cannot leave key in vehicle. Also stability control light comes on every morning., and car stalls every time I make a turn while driving. This is dangerous. Took my vehicle in to the dealership who claimed that all recall and campaign situations had been resolved with my vehicle.

In November 2018, we had a rattling noise during low speeds, which turned out to be a problem with the engine (engine seized up during warm up inspection by mechanic). The engine was replaced for free due to an extended warranty that was part of a recall and settlement agreement with Hyundai. In February 2019, the check engine light came on, which was for a damaged catalytic converter and cost over $2000 to replace. Last month, we received a recall notice from Hyundai stating " Hyundai is conducting a safety recall in the United States to confirm the high pressure fuel pipe was properly connected by Hyundai dealers to the high-pressure fuel pump outlet when the engine was replaced under recalls 132 and 162. " we have an appointment scheduled for this service. There is a new recall for other Kia and Hyundai models that include the catalytic converter, but it has not been included for our model year.

My Hyundai Sonata began increasingly consuming oil rapidly for a couple months until it got to me putting in 1 quart every 200 miles!!! that destroyed the catalytic converter, although the tech at the dealer tried to tell me it was due to fuel. Experts at both the exhaust shop and Ford dealership (where I bought it used), refuted that and told me it was definitely due primarily from the engine consuming way too much oil. Hyundai required me to do 5 oil consumption tests at their delaership before they can verify and document the engine is having problems! but in the meantime my engine could likely blow up/seize up, as the 2011 Hyundai Sonata is notorious for that and they recalled 470,000+ already!! I only have 3 oil consumption tests, and it shows 200 miles per quart!! my cat converter is now clogged and my car lost power. So now in a catch 22 (maybe on purpose?). I can't get 5 tests without replacing my catalytic converter, but since engine is losing 1 quart per 200 miles that oil will soon destroy any new converter I put on within 1 or 2 months, if not less!! so this is ruining the car, and I have started a case number with corporate Hyundai in California. They haven't called me back in several days all the while I don't have a car to use. Engine burning 1 quart per 200 miles or less is terrible....engine is ruined! and it's not safe!! as I have read so many 2011 Sonata owners telling about their car engines seizing up, locking up while driving 65 mph on the highway in the middle lane!! I hope Hyundai takes responsibility as I still owe $9,000 on this car!

The contact owns a 2011 Hyundai Sonata. Within weeks of owning the vehicle, there had been multiple failures. The vehicle had a drastic reduction in speed without warning, there was a strong burning odor, and the vehicle stalled randomly several times. The vehicle had to be towed to patty peck Honda (555 sunnybrook rd, ridgeland, ms 39157, (601) 957-3400) due to it stalling. The dealer recommended that the vehicle be serviced by an authorized dealer. The vehicle was taken to wilson premier Hyundai (450 steed rd, ridgeland, ms 39157, (601) 856-6423) where it was diagnosed that there was a loss of oil that required that the oil constantly be refilled and metal shavings were present in the engine assembly. Also, the catalytic converter needed to be replaced. The catalytic converter was replaced, but the burning odor worsened. The dealer provided a loaner vehicle, but the contact's vehicle was returned under the guidelines that an oil consumption test should be performed every 1,000 miles. The vehicle was not repaired. The contact felt that the manufacturer and the dealer failed to provide a permanent remedy to repair the vehicle. The manufacturer was notified numerous times. The approximate failure mileage was 73,000.
