ENGINE
Engine lost 4 quarts of oil in a little over 2000 miles after service (2nd event). Engine oil caution light came on with 1 quart of oil left in the engine. Oil dip stick is tarnish brown, evidence of an over heated engine. This car only has 63000 miles on it and I believe it's a danger to drive on any highway. I've visited the dealership which has serviced this car since purchase and they suggest an oil consumption test be performed, which I find unnecessary and to add, the cost of the test could be charge to the customer. I have read of the deadly fires and crashes due to these engines failures due to oil consumptions problems. Recall them all now! There is no room for profit over safety in this situation!!!

Car has been knocking for a couple of months now, check engine started flashing and it lost acceleration. Towed to shop and code for knock sensor was reading bad. Shop replaced knock sensor, I picked car up and drove away and it happened again. Engine light flashing and lost acceleration, took back to shop and the next day which would be today they said take to the dealer cause it's still reading for knock sensor. My 2013 hyundai sonata 2.0 is now at the dealership in line with the rest of the seized engines. So I have spent $800 ($613 for shop and $200 rental car) and my car is still not drivable. Now I'm back in a rental at$300 a week until hyundai diagnose, test, and approve the process of fixing the issue with my 2013 hyundai sonata 2.0, it has a life time warranty! This will be the second 2013 hyundai sonata I have owned with the engine seizing up! Back in Nov. 2021 I went thru this very same thing!

My ITMS has failed. It’s happened 5 times now where My car will say it’s over heating and go into limp mode. Then within seconds it will act like nothing happened and drive normal. My fan runs constantly and my oil temp is always high. The dealer has refused to fix the problem even with multiple repair sheets from other owners who’ve had the same problems

The issue is well known across the DN8 platform, hundreds if not thousands of people have this problem.Car and driver even did an article on a car with this same 2.5L turbo DCT engine having the same problem! The problem is the ITMS or thermostat housing unit. I first experienced this getting on to a highway, I lost all acceleration, the turbo dropped to 0 pSI and I received an engine overheating warning on the dash. After pulling over the car resumed normal driving, but with oil temps running 30-40 degrees higher than normal. Since then, I have had loss of boost and acceleration when passing around cars which has almost caused accidents, oil temps constantly running very high and fans constantly running on full blast even after car is off. I have been to the service center 4 times, and they have failed to "replicate" the issue and stated the fan and oil problem is "normal" which it is not. This problem needs to be addressed before somebody gets seriously hurt due to loss of power unexpectedly while driving. PLEASE help! Thank you for your time.

A week ago (June 5th) car had been running fine, then all of a sudden lost power. Wouldn’t pick up speed, several warning lights came on and then it just died. Did hear a knocking noise right before it died. It is currently at dealership and was given a time frame of approximately 3 weeks to fully diagnose. This is obviously frustrating as I just got this car at end of March and it is being financed, so paying for a broke down car at this point! I hope that Hyundai manufacturer fixes this issue because it seems to be happening to quite a few people upon doing some research!

EXTERIOR LIGHTING
There was no specific "incidence" to report. This is an on-going issue for a long time. Low beam headlights do not illuminate the road sufficiently for safe driving. Have had it to the dealer to insure the lights are adjusted to spec, but it was no better. Asked that they raise the beams; while a little better isibility, oncoming traffic was blinded and flashing me to lower the beams. Had the lights adjusted back to spec. I am now afraid to drive it at night in unlit areas - you just cannot see the road and easily outrun the reach of these poor lights.

Unknown, my vehicle sounds like the valves are knocking. I've had my oil changed on time since I've own the vehicle. While driving, my car shuts off. I pulled over and started it again and 3 mins later it shuts back off. Now I cannot start my vehicle. It literally won't allow me to. And there's metal shavings all throughout my engine.
