2012 EQUUS TRANSMISSION ISSUES

[bglee8]

I just purchased a 2012 used Equus with 53k miles and up to this it’s been a horrible experience. When I purchased it the previous owner had 22” rims on it. It drove fine for about a week but then began to kickback between 20 and 45mph..RPMs revving up to 5 no check engine light. I brought it to the Hyundai Genesis dealership who diagnosed and came back with their assessment that it needed a transmission. After communication back and forth with my extended warranty 9 days later the extended warranty said we are not paying for a new transmission but will pay for one that is used with equal or lesser miles. It was written in the contract. I told Hyundai that I was not willing to pay the 2200 difference and to give me my car back. I asked them if they performed the TSB that Hyundai had issued for this car one stating to not replace the transmission but to change the emodule(it’s a 350 dollar part). They stated it did not code for that TSB so they didn’t do it. While my car was at the dealership I ordered the original stock wheels and mentioned that since they indicated the larger wheels may have compromised the transmission why not put the original stock on and rediagnose. They did not comply. I took my car back put the original stock back on and the car appeared to be driving fine before I sent it back to the original dealer I purchased it from and told them they must use their resources to fix the transmission within the parameters the extended warranty they sold me gave. I was hesitant because the car was driving fine but I was going by the recommendation that Hyundai gave. The transmission was changed out to a USED tranny with 49k miles on it.The mechanic expressed that he did not feel the original had a problem but did not have my number and the original dealership told him to replace it because that is what Hyundai recommended and I wanted which was correct. I picked it up drove it for about 10 miles and noticed again it was not driving right similar kickback as it did with the larger wheels.Right now I’m out $1300 for the original wheels and tires 400 for rental car and 140 for a diagnosis.I called Hyundai corporate filed a complaint and they are suppose to issue a credit for a transmission diagnosis. In the meantime I have returned my car to the mechanic that put in the new used transmission and asked him to put my original back in. Can anyone provide any insight on the state of a 2012 Equus transmission. It’s sensitivities to different wheels different tires etc.

Given that you had the same problem with two different transmissions, I'd conclude it is not the transmission. Originally I'd have thought that but the swap shows different.

I'm thinking there is something in the controls system. Something is telling the tranny to not shift or stay in a neutral position, thus the run up of rpm that is mistake for slipping. You may need to fins someone that understands the entire system as it can be some external modulator, vacuum line, ecu, etc.

Seriously doubt the wheels had anything to do with it. Not sure how any mechanic could come to that conclusion.

Here I go again. The mechanic did a reset to the transmission because he said he could not return it if he could not prove it was malfunctioning well 5 days later it’s malfunctioning. This is stupid now.

It crossed my mind. You are correct, directly, but, give the 22" wheels, how did the previous owner drive the car? I can see how someone can convert a luxury sedan to a Pimpmobile or Drug Express and beat the hell out of it.

There is no way for me to know how the previous owners of both of the transmission drove what I do know is that a car like this with just over 50k miles on both transmissions having transmission problems appears to be a flaw in the 8 speed transmission itself. I thought Hyundai had it’s act together.

So this car ran well for 5 days and then back to the same old irregular shifting and knocking.
