This is my second report and no one helped me. I have a safety issue and I am driving an unsafe car Hyundia refuses to help me.
On or about August 13 2022, I notice the oil engine light come for a second, then it went off. After parking vehicle at my home and letting the engine cool off a bit and oil to settle, I checked dipstick only to find out that is was showing DRY no oils whatsoever, I then bought 1 qt of oil and added it to engine still dip stick showed dry and not a drop of oil on it. With still 3,000 miles to go before my next oil change, I decided to take it to PepBoys for a new oil change. After one week dip stick was showing oil on the low side and this time the metal on the stick showed whiteish, like it had been over heated. after this decided to take it to dealership GOSH HYUNDAI In Hemet 92545. I was told it would take 2 days to do some checks and get it ready for an oil consumption test. That is drive vehicle 1000 miles then take it in for another inspection (hopefully 1 day) then getting it back, drive another 1000 miles, then take back for another inspection. Being this my only Vehicle at this time, I am not sure why it takes so long to figure this out. OH did I mention Hyundai headquarters (I'm guessing) has to approve the oil consumption test, otherwise I am out a vehicle and have to pay for repairs. Not too mention the brake fluid reservoir is doing the exact same thing, fluid is being completely replaced every month to month and a half, by replace I mean adding a full reservoir worth of fluid because it seems to be evaporating. I am on the the third time adding fluid to this vehicle after GOSH Hyundai worked on my brakes (10000 miles a go). But this one I will have to pay 165 dollars for them to check it out. Nothing was said about me paying for engine oil issue check, plus they had me sign a affidavit to make sure I was the only owner on vehicle witch I am...So now the waiting game begins and to wait until someone makes a decision about fixing this issues?!!

MY CAR IS A 2017 SONATA SE 2.4L JUST SHY OF 21K MILES. I USE THE PARKING BRAKE ALL THE TIME AND YESTERDAY WHEN I GOT HOME AND DEPRESSED THE PARKING BRAKE PEDAL IT WENT ALL THE WAY TO THE FLOOR - NO MORE WORKING PARKING BRAKE! ON THE FLOOR I FOUND A SMALL LOCKNUT AND A WASHER THAT FELL OFF THE THREADED END OF THE CABLE AT THE PARKING BRAKE PEDAL. I REPAIRED IT MYSELF BY ADDING A SECOND REGULAR M6 NUT (10MM WRENCH) AND LOCKED THE TWO NUTS TOGETHER. ADDING THE SECOND NUT AND LOCKING THEM TOGETHER SHOULD PERMANENTLY FIX THE ISSUE.

THE SENSORS FOR BRAKING DID NOT WORK. I HAD AN ACCIDENT WHERE I REAR ENDED A TRUCK. THE BRAKES DIDN'T WORK, ONLY SLID INTO THE BACK OF THE TRUCK. I WAS ON A BUSY STREET WHEN AN EMERGENCY VEHICLE TURNED ON SIRENS AT THE LAST SECOND. THE TRUCK STOPPED AS IT SHOULD HAVE. I BRAKED AS HARD AS POSSIBLE BUT THE CAR KEPT GOING UNTIL IT COLLIDED INTO THE TRUCK. I HAVE READ REPORTS ON THE 2017 SONATA WHICH STATES THE CAR WILL STOP WHEN IT SENSES IMMINENT DANGER. THIS ONE DIDN'T. MY CONCERN IS- IS THERE MORE CARS LIKE THIS ONE OUT THERE THAT DON'T WORK AS IT SHOULD. I PURCHASED THIS CAR 02/2017. HAD ONLY 23 MILES. I TOOK MY CAR IN FOR SERVICING THE DAY BEFORE AND WAS TOLD THERE WAS A RECALL ON THE CAR. I NEVER RECEIVED A NOTICE OF RECALL AND STILL HAVEN'T. SUPOSSEDLY THAT WAS TAKEN CARE OF. THE INVOICE SHOWS THE RECALL WAS FOR ALTN SCREW. IT SHOWS IT WAS FOR SANTA FE SPT/SONATA.
