We’ve taken the vehicle to two different Infiniti dealerships (Sewell and Crest) multiple times due to engine rattling, vibration noises, and propulsion issues. Unfortunately, we haven’t received any resolution or fix for these problems. We tried to upload a video with sound as reference but the platform doesn’t allow us to. We experienced similar issue that resulted in total engine failure on the highway with our children in the car in our Yukon Denali. We are fearful that something similar will occur. Please Help!!!
I have received email from my car dealer Grubbs Infiniti in Grapevine, TX. The email was regarding a recall for potential engine issues. I called my dealer and scheduled an inspection. When I sent my vehicle for inspection the dealer replaced my engine with a new engine without my consent. After the engine replacement I’ve received my vehicle back and I’ve been having issues where my vehicle suddenly got jammed while I was driving in my community. I called my dealer again and they took the car, fixed it and sent it back. Now after receiving the car my car is not starting and I did a jump start, eventually my car got started but I got an emission control system malfunction error and my car is not starting anymore. With all this I lost the confidence on my car and I need some kind of justice here. Thank you!!
