It's also worth mentioning that since month one of ownership, the vehicle has displayed some unnatural characteristics. Under hard throttle the engine created a tone that was very much discomforting and not confidence inspiring. It was abundantly clear the engine struggles to move this heavy AWD vehicle. The vehicle is so aggressive when it comes to shifting up to the next gear, I find myself doing 38-40 mph and the vehicle would be in 8th gear. When I would try to accelerate naturally the vehicle growls and vibrates and makes crunchy sounds as it struggles to accelerate against 8th gear. It's gotten so loud it can be heard over the AC and low volume radio. It's across the board as well, this issue occurs at highway speeds down to neighborhood driving. It will wholistically shift into too high of a gear whenever its possible, and the only way to prevent this experience is to manually shift the vehicle. This demonstrates that the driver is smarter in shifting requirements over the TCU. Furthermore, the gas milage for the first 12-to-15,000 miles failed to meet the specified expectations, additionally, the computer is aggressive in its calculations for the achieved MPG, and hand calculations tend to show they are off by 2 to 3 mpg consistently. I took the opportunity to change the oil in the vehicle early (1,500 miles) knowing that break in periods could have small metal build up as components seat and find their mark etc. To my Suprise, I was met with a substantial (in my opinion) amount of rolled metal material and metallic material in the oil. I took pictures and videos and decided to continue to change the oil every 2,000 miles to document changes. Currently the vehicles last oil change was at 25,000 miles and there is still a concerning amount of metallic material and occasionally rolled pieces of metal during oil changes.","products":[{"type":"Vehicle","productYear":"2022","productMake":"HYUNDAI","productModel":"TUCSON","manufacturer":"Hyundai Motor America"}]}]}
