2016 Hyundai Santa FeRecalls, problems, MPG & safety

“1. Component/System Failure & Availability: The failed component is the engine's internal Camshaft Variable Valve Timing (CVVT) phaser backing bolt within the 3.3L V6 engine assembly. An internal factory bolt unthreaded, backed out, and physically pierced directly through the upper valve cover. The vehicle and intact failed engine are currently located at an authorized Hyundai dealership service center in [XXX], and remain fully available for immediate physical inspection by federal investigators upon request. 2. Safety Risk: An internal engine bolt unthreading and puncturing through the valve cover creates an extreme safety hazard. A high-velocity metal bolt piercing the engine casing causes immediate engine seizure, sudden loss of motive power at highway speeds, loss of power steering/braking assistance, and massive pressurized oil discharge directly onto red-hot exhaust manifolds, posing a severe risk of sudden catastrophic vehicle fire and multi-vehicle highway collisions. 3. Dealer/Independent Confirmation: Yes. The failure was formally inspected, reproduced, and confirmed by an authorized Hyundai dealership service department. Dealership technicians…”

“Hard Shift occurs between gear 1 and gear 2. The hard shift lurches the entire car. It occurs on both upshift and downshift. The hard shift occurs on cold starts. The problem goes away when you turn the vehicle off and then back on. There are no check engine lights. The dealer can't replicate the problem.”

“Abs system is randomly locking up calipers causing a dangerous speed wobble. Dealership can't re create so won't diagnose. Have had to replace all brake calipers and components were near new but ruined because of abs applying brakes when unnecessary. Vehicle is very unsafe to drive, pulled hard to left at one point veering me into oncoming traffic. Independent mechanic has made caliper release by manually releasing abs system. Same results were not found by releasing pressure at master cylinder making abs the obvious culprit. No warning lights but I just replaced two cracked rotors on rear at 130k miles. That should not happen. Has caused hub readings of 270 on three different tires at 3 different times. Santa fe has recall on this system for every year but mine, very curious as to why not. If this was not a dealership only part , it might not be such a big issue, but being it is main source of stopping a 4000 lb vehicle, I have concerns. Hyundai dealership was very condescending and of little to no help. I have an Independent are certified mechanic who is happy to talk with you if needed. Please help, as of right now am.making payments on an unsafe vehicle…”
