NHTSA Complaint #11442350 — 2018 HYUNDAI TUCSON

Purchased new on 5/30/2018. 3/2021 I noticed shaking, noises, pinging, whining sounds and vibration coming from engine as I turn engine on / off and in drive. 3/24/2021 I brought vehicle for inspection. Service Advisor felt the shaking, vibrations and heard the pinging / noises and whining sounds as I turned the vehicle off. Vehicle went for oil change and inspection, stayed overnight and no fault found, service bay stated they could not reproduce the occurrence. The sensations worsened and I brought vehicle back on 3/30/2021 for inspection as I did not feel safe driving vehicle. 4/02/2021 dealer said the sensations could not be detectable and it was suggested that maybe the Turbo dual clutch engine. 10/15/2021 the air conditioner failed. Brought vehicle in for inspection. Service performed diagnostic testing on vehicle and found internal failure on a/c compressor. New compressor was ordered and replaced. Replacement air conditioner is not as powerful or cold as original part. Vehicle is still making pinging, whining, vibrations. 11/29/2021, engine light came on. I reversed out of a parking spot and it felt different. Put gear in drive and immediately the gas pedal went to half way to floor and the vehicle jerked and then seemed to catch the gear. Then the pedal went to the floor and there was no go, then it kicked in. Repeated multiple times. Tried reverse and there was none. No rpm movement and quickly came a strong burning smell. Had vehicle towed dealer. All vehicle services are current and up to date.
