The engine started knocking while I was driving. The car experienced sluggish performance afterwards, and hesitancy in acceleration. Hyundai has recalled other vehicles for engine knocking, but not the Azera.

The engine failed in this vehicle as I was driving down the road. It immediately started knocking violently without warning. I was left stranded with my 4 children and had to pay for towing. The problem still persists upon starting. The vehicle had been inspected numerous times prior to incident due to a ticking noise upon cranking and I was informed by dealer that this is normal. Upon incident there was no warning lights or inclination that this was going to happen. I have since been told by multiple mechanics that the crank rod is faulty in this 3.3L Hyundai engine and that in order to replace it you must buy a refurbished engine with an aftermarket part due to the faulty manufacturer part.

When starting the car you hear a loud clattering noise. And it doesn't go away. I was told I needed a oil change, oil change was performed. The noise was still happening took it back to the dealer then was told I needed a timing tension belt. Wasted my money because the issue still wasn't fixed. And now when I start my car it a louder noise coming from my engine and whiling driving my car stalls really back and while driving I can still hear the noise.
