Business ProfileforSt. Charles Nissan Hyundai

My husband called this dealership early March of 2024, which we have been informed is a recorded line, about fixing a couple of issues with his Nissan truck since it was a Nissan dealership. He spoke with a gentleman named *****. My husband informed *****, to look over the truck and please tell him everything that is wrong and potential pricing. If a loan needed to be done to fix the problem or problems, we can look into that. My husband biggest concern was a check engine light showing a code related to turbo and a def light showing see dealership. After a week of having this vehicle, he was informed by ***** that he could fix this issue, fixing a part of the Turbo. He has worked on multiple vehicles with similar complaints and it fixed the problem. My husband stated if he's positive it will fix it, lets go forward with it. After the part was installed, we got a phone call stating it did not work, *****, now ran the code and called the "Nissan" headquarters and the code is related to turbo and would roughly cost around 6000, but he still does not have an answer as to why the def light was on. I'm frustrated because we paid 2200, including tire rotation and oil change for something that did not fix the problem and we still don't have answers. He also changed a ground cable that we told him not to, The vehicle is still in the drive way and is not able to be driven. It now says it will go in limp mode in 50 miles. I don't agree with attempting to fix a vehicle w/o even running the code, after the fact the part was installed. On 4/16 I called Nissan consumer affairs and due to this dealership being independent, will have to talk to owner. On 4/17 ***** said nothing they can do. I spoke with the manager ********************* on 05/20, he said he will investigate. On 5/30 and 06/06 I have left messages for ** to return my call concerning what he had found and no response. I do not feel like I should pay for something that did not correct the problem. I feel ignored.Pat/******
