| Description of the problem | We bought our sonata in 2017, since then it has gone into "limp mode" (while in motion every time) three times. We took it to the dealership the first time it happened and they claimed it needed a "software update". The update didn't last too long because it went into "limp mode" once again. We took it back to the dealership (as instructed by the dealership) and they refused to provide services until a diagnosis fee was provided; even though they told us to bring it back if it happened again and they would fix the problem at no cost. We refused to pay the fee since they had told us they would fix it for free and the car sat for about a month or two while we used my husbands parents vehicle (since it is our only vehicle). We eventually drove it to a third party mechanic (while being jerked around because the car would lose power and going 20mph in a 35mph zone) and he changed out the knocker rod and head gaskets after stating it was the issue after hooking it up to a diagnostic computer and getting codes to change those specific items. It seemed to work for about five months, until recently when my husband and i were driving on the highway (in traffic) when it went into "limp mode" once more. The dealership decided to take the car in to look at it, provided a rental car and indicated the car needed a new engine before service (because it keeps going into limp mode). They called us yesterday to let us know that it just needed another "software update". I have been told software updates don't resolve the issue, it pushes the problem back and it will reoccur. I have already called and filed a complaint with the dealerships consumer affairs department (that the service manager from the dealership gave us) and am waiting for a call back. This car is not safe. I have a toddler and am pregnant and fear for my families safety while driving this vehicle. |
