At 1540 miles 2015 Hyundai Sonata limited engine cam advance sensor failed. This caused engine running rough and limited power with inability to climb hills without constantly downshifting. Highway driving is dangerous due to inability to accelerate and merge and loss of power on hills. Other owners are unable to start their cars altogether. Engine monitor warned of problem and recommended full systems diagnostic which pointed to cam sensor issue. Supply of sensors was backlogged due to multiple failures nationally. This is also evidenced by the number of online owner complaints for the same issue many stating long delays in obtaining the part and multiple part failures. In my case, after 200 miles with the new sensor if failed a second time and I am again waiting for parts. The vehicle now has 1700 miles on it since new. For a new vehicle this is a totally unacceptable level of quality. While I was told the O-ring seal fails causing oil to saturate the sensor I personally believe they do not know the full reason for the failures, I.e. poor sensor manufacturing, materials issue, O-ring issue etc. In speaking with Hyundai corporate personnel it became obvious to me that they are trying to avoid a national recall by understating the scope of this problem nationally and trying to minimalize the extent of the problem in our conversations. I suggest an investigation to determine the extent of the issue and see if it warrants a recall. For other owners or potential buyers, while this failure has been my primary complaint I have noted other issues with the electronic warning sensor inconsistency and cabin electronics systems which have not been resolved. This my first experience with owning a Hyundai and I am terribly disappointed. Next step is lemon law filing.

Brand new car purchased and few issues. 1. gas gauge only goes up to 7/8 even with full tank fill up. 2. gas mileage does not seem to indicate correct mileage. With full tank gas, the indicator shows 450+ miles, but actual mileage is 300~350 miles. 3. error occurs when playing songs from iphone 6 using usb cable.
