Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: The 2011 Sonata has a seriously defective engine that seizes without warning. It was awarded the dubious honor of being the first CarTalk / CarComplaints Turd of the Week in late September 2015.

A class action lawsuit was filed in May 2015 against Hyundai that claims the 2.4L Sonata engine is defective. More info here.

Sonata

I have complied with Hyundai in regards to the two recalls on the vehicle. Although, my vehicle has sat at the dealership since November 5th 2015. The dealership has yet to receive a new engine from the manufacturer. Furthermore, I still pay payments on the vehicle and have done so before the recall was released as well as even after it was sent to the dealer, as requested by Hyundai. I spoke to Hyundai today as to an update to when this will be completed and they did not have an answer. I sent them a letter requesting that they buy back the vehicle do to the safety concerns as well as the delay in fixing this matter. They declined and this is why I am filing a complaint. They have not or have they ever taken accountability for these issues from my standpoint and the car has lost substantial value due to these ongoing recalls. I am paying on a vehicle that is no longer worth the payments. I have requested a buy back due to the quality of the product Hyundai made. They falsified their commercials and hyped up the quality of their product and no longer are they standing behind it.

Sonata 4-cyl

  • 94,000 miles
October 3rd 2015, I was driving on highway 78 West. I was in the vehicle with my 3 year old daughter. I was driving in a 2 way lane that was under construction. All off a sudden without any warning my vehicle started to decelerate on the highway. I immediately had no control and my speed was decreasing fast. I was in the left lane and in matter of 4-7 minutes my car engine was shutting down on the highway. I was almost hit by multiple trucks who continued to fly by my vehicle on the highway as I tried to find some where in enough time to bear off. Putting me and my 3 year old daughter in immediate danger. Needless to say I was terrified. I was finally able to pull off into the right lane and pull my vehicle into the shoulder of the highway. Since I was in an area that was under construction on this highway the shoulder space was very limited. I could feel the trucks pass my car and I was scared for my life and my daughter?S life. I had an immediate panic attack and thought my daughter and myself was going to die. This has caused a great deal of hardship on myself and my daughter. We have been without our vehicle since this incident. Hyundai in lebanon, pa has had my vehicle since 10/3/15 and continue to give me the run around. They say they ordered a new engine, but it has not shipped to the dealer yet. This incident has created a tremendous hardship for me and my family. I continue to be at a disadvantage as I am driving a rented vehicle. Meanwhile I continue to pay for a car I have not driven for over 3 months. Your immediate assistance would be appreciated. This issue I am having with my vehicle is due to a recall campaign 132. This recall was due to the engine malfunction that Hyundai is aware of. My vehicle stalled while in motion on the highway, putting my life and my 3 year old daughter's life at risk.

There is a recall on my vehicle engine. I took my car to the dealer and they inspected the engine for the defective part (engine). They said the car doesn't met the requirement for fix or replacement. However, they increased the oil amount from 4.5 quarts to 5.5 and change the oil dip stick without explanation when I asked why. I believe they are attempting to cover up the problem with temporary fix. Can you investigate in to this matter please. I call them several times about the situation with the dealership and the changes made without explanation. After several weeks of waiting for them to respond I call them and the costumer service person on the phone gave me an explanation, again not responded to my question directly but by someone who only answer the phone. Please help or advise!
