My engine failed and was repaired under a campaign recall. Tim Short in Pikeville ky kept my vehicle 3 months to install new engine. Check engine light came on on the way home the day I picked it up. Made appointments to go back and have it checked and they said catalytic converter was clogging up but it would be my responsibility to fox it at my cost. Asked If it would be safe to drive oh yes you may lose a little Power over time but should be fine. Left the dealership and didn't make it home the car started vibrating and shit down got it started back and barely made it to a place to pull off. Car had no power, smoke boiling out of engine and exhaust. Dealership and hyundai refused to cover having it towed back. This last engine was the 3rd engine put in this vehicle due to recalls and this one didn't even make it 3 weeks . There is definitely an engine problem with hyuandi.. inhav been left without a vehicle for 3 months and have to have it towed back again at my cost. I wasn't even given a rental while it was being repaired. The car has 121,000 miles but has had 3 failed engines. Something needs to be done.

Was diving the car and experienced system failure, no prior warnings or issues. Had regular oil changes throughout, however, a few days ago in normal driving conditions, the check engine light began flashing and car felt like it was losing power. Had to pull over to the side of the road and shut the car down. Vehicle would not restart and had to have the vehicle towed to the nearest dealer. Dealer informed us that the "engine was locked" and had to be replaced, car only has 62K miles on it. Research online has uncovered others that have had the same experience and issue with the 2015 sonata that has resulted in replacement of the entire engine. Dealer has not confirmed if repairs will be covered, but if we had been in a high traffic area the car losing power suddenly without warning could have resulted in serious injury getting the car out of fast paced traffic. There appears to be an known issue, as when we asked the dealer about others on-line who have had this happen, dealers response was "we have seen this before, yes." But, now we have been close to a week without a car, no loaner from the dealer, and no indication on how this will be fixed.

I was driving on the expressway. After about 18 miles the vehicle slowly decelerated to a stop. I was able to safely exit the expressway to the side street. I turned the car off for a few minutes. It started back up but has not accelerated pass 20/25 miles. There’s also major oil consumption. Camshaft position & ccv issues yearly requiring sensors to be replaced. Increased gas consumption. There’s also been a humming sound coming from the car that’s not been able to be diagnosed by any mechanics.

I have to continue to put oil in my car and get my oil change every 30 days due to oil leak. I have been to the mechanic and had my oil gasket changed, engine clean etc… and I’m still buying if oil and getting oil changes. I would get oil change and as soon as it gets close to 30 days my oil light comes on.

I had closed from work one morning and was headed home. Just a few seconds after taking off, my engine completely shut down. Thank goodness I wasn't in on a highway or at a heavy traffic area. I managed to park my car by the road side & tried to restart my engine, but the car wouldn't start. I towed the car to the nearest mechanic, only to hear that my engine is done & needs replacement. I've constantly kept up with frequent oil changes & always used synthetic oil. Current odometer reading is 153k & I believe the car still has the potential to stay on the road a longer time if the engine is taken care of. I've reported the issue to my nearest Hyundai dealership & they've asked me to tow it to them, but they can't promise that they'll take care of the problem. Worst of all, that's the only car I have & I'm still making payment on the car.

My Sonata is burning excessive oil since January 2022 have to add a quart a week but there is no oil leak.

1/2022. My vehicle start leaking oil. Vehicle was under warranty. Had multiple things replaced. Thought oil leak was fixed. Not even a month later in 2/2022, vehicle was leaking oil again. Brought it back to dealer & they redid gaskets, seals, etc. 4/22/22, have no even put 3000 miles on vehicle since it was at the dealership & there was a knocking noise coming from under my hood. Called the dealership and they said I needed to get it back to them. Oil consumption test was never done because it was assumed that my oil was low because it was leaking. Both times oil was put in my vehicle. On 4/28/22, I was at work and went outside to check my oil and there was little to no oil on the stick. I immediately added 5 quarts of oil which is required for my vehicle. The knocking did not stop. I left work to run a brief Errand on 4/29/22, and had just pulled out of work onto a very busy four-lane highway. All of a sudden I hear this big boom under my hood, my car locks up and my oil light comes on. I immediately took my foot off of the gas and coasted into the next driveway at a business. There was oil all over the road and pouring out from under my car. It happened to be an auto parts store. A mechanic came outside and looked and said a rod went through my engine block & oil was pouring out of my car. I started to have an anxiety attack and went into shock. Luckily I was not on the interstate because it could have been very bad. I am now without a car. None of the rental car Places have any vehicles available and I have a full-time job & single mom with 2 kids. The dealership was nice enough to have my car towed to them 45 minutes away. They Then tell me about an oil consumption problem with Hyundai and there is a big class action lawsuit. This should have never happened. Apparently the oil consumption was never sent out as a recall or anything else so I was unaware of it to even know to check my car other than regular oil changes.

My 2015 Sonata has been going through at least a quart to a quart and a half of oil every thousand miles. I researched this and found out that the 2015 sonatas have a very common problem where the engine needs to be replaced. There was huge class action suit against Hyundai and I'm worried that this is going to lead to bigger problems for me. I have gone to the dealer for 5 times and they keep telling me I'm not burning enough oil to justify the engine replacement but I'm not comfortable with their report.

There's an oil line to the turbocharger; my guess is to cool the turbo and it came off spraying oil all over the engine compartment and when it hits the turbo the heat from the turbo would create smoke that would get into the passenger compartment and billowing out from under the hood. Hyundai had a recall campaign to fix this issue for the same 2.0T engine but only for Sonata models from 2011-2014 and they deny that this recall applies to my car because it's MY2015. Same car, same engine, same turbo oil feed line and they refuse to honor repair costs for recall campaign 16-01-071. I had to go through this risky incident and then have to pay $720 in repairs that was caused by a design flaw.

Was pulling out of a parking lot and the engine stalled. Would not crank over again. Mechanic took the timing cover off to inspect and found timing chains are all in working order. Will all engine belt driven accessories disconnect and timing cover off. Engine cannot be rotated with a breaker bar. Technician says the bearings are seized.

Oil consumption, engine locked

We have had some issues but take very good care of the car maintenance wise. The car went into limp mode and we took it in they ran it and came up as the knock sensor.. I noticed there was a huge recall for these cars. What can I do? It has 140000 miles and again we keep up on the car. Is this something I need to seek counsel for? Thank you for your time. I look forward to hearing from you, Dominique
