Yikes! I'm sorry you'll be without your vehicle for that long, but hey - a new engine for free!Update 3/28/19: On 3/26, I wrote a very detail letter of concern with several probing questions to Hyundai's Consumer Affairs (email). I followed this up with a phonecall as well on 3/27. In that call, they confirmed that the email letter was already in a "file" linked with my VIN - they assigned me a case number and said I should hear back from a case manager within 3 to 5 business days. Have not heard back from them, but I did get a call from the dealership this morning saying they have been instructed to replace my engine. Said that it will probably be 5 or 6 weeks - which apparently, most of this time is for the engine to arrive (they said my car would be ready in about 3 days after it arrived).
I picked my car up today...they only replaced the knock sensor. The tech came and told me that what my test results show do not indicate engine failure at all, so he thinks the new wiring harness and new knock sensor will do the trick. I hope he's right! I've only driven about 15 miles since the new sensor was installed...I won't feel confident for another 900+ miles.
Oh, and I'd like to hear your experience with the Consumer Affairs case. While I do think it sped the process up a bit for me (dealing with the dealership), the case manager did not help with anything else. I had asked for more details on this update and all it's shortcomings and numbers, etc. She said she did not have that information. She was basically there to be a middle-man with my dealership. Um...thanks.
