The engine is burning over 5 quarts of oil between 600 and 1000 miles. The engine is the 2.4 litre and it is doing the same as the 2014 and previous model. It is also known that the 2016 has the same issue. Hyundai refuses to replace the motor or cover any cost. They are saying that the car is out of warranty when it has been in the shop for oil consumption pre-mileage but they said it was normal to be a quart or 2 low. Now the motor will be empty by 600 to 1000 miles. The dealers wants to put chemicals in the motor at a cost of 200 plus with now promise of resolving the issue. In addition it has been proven that these quick fixes are catastrophic and will cost more than an engine maybe a life in traffic.

Car fire. Car was brought in for service on a Saturday. Car started smoking on drive home. Called Hyundai and they said it was okay. Monday car was booked to be brought back to Hyundai because smoking wouldn’t stop and car caught fire. Incident 1/17/22. No inspection to date, no warning lights went off. Just smoke started and then flames.

215/55 R 17 My right rear tire has been losing air for at least 6 months. My tire pressure light is constantly on. I had my tire inspected and was told all 4 tires are compromised. The mechanic told me that my tires were wavy??? and that the tread inside my tires were damaged and I needed to replace all 4 tires. He also said my car would not pass inspection because of this defect in the tires. I feel my safety is at risk because of the inconsistent pressure that the tires may blow at any time.

During weekend road trip, on the way back, engine has developed knocking noise, unusual vibrations, and loss of power. Car was able to make it home at low speeds with minimal acceleration. Oil check revealed that all of oil was burned up over a few days, as the oil check before the weekend trip showed full levels. Dealer would not even accept looking at the car for over a month, before their first available appointment. Independent mechanic confirmed engine knocking, burned up oil. They recommended engine replacement, but were not able to complete the job as the company would not make replacement parts available to them. Dealer has finally accepted car, also confirmed knocking noise and burned up oil. It would take another month for dealer to produce a repair quote -- $14,000 for engine replacement and additional 2 months of wait time for some parts to arrive -- much higher than what I understand it typically costs for a full engine replacement, but the dealer is left as the only option to charge however much they want, as independent services are blocked from acquiring needed parts. 87,000 mi in just over 6 years of use. No warning lights on the dash. No OBD status codes. All together this would add up to at least 5 months of inoperable car, and what looks to be a very inflated repair bill. Dealer is recommending a purchase of a new car from them instead.

Hyundai reprogramed their Theta engines to prevent an ongoing problem related to Theta engines not receiving oil to the crankshaft and connecting rod bearings. The software modification was done by an unknown software house. When I got the first notice, I asked both the local dealer, and the official Hyundai site if this software would cut power, potentially at the wrong time, like going up an entrance ramp. I got no response and I found out why. I tried entering a highway where traffic was at 75 mph. When I got onto the ramp the car was running fine. Suddenly the power just went away. I had the gas pedal all the way to the floor and watched the tachometer and speedometer go down rather than up. I pulled off at the next exit and switched the programming on my transmission to normal from econ mode. Up the ramp I went, and car started slowing down. Tried one more time using the sport mode and the power went away. I'm afraid to try and run on a freeway at rush our because of the lack of power. I think the needs to be a review of the software and see if changes can be made.

Car engine light turns on indicating connecting rod bearing failure. Vehicle has stopped running properly while driving at high speeds & caused safety concerns. Issue has shown to be consistent across many other Hyundai vehicles. Issue has not yet been checked by manufacturer but is available for future inspection.

The Camshaft Seals are defective and cause the engine light to come on and also I experience power loss while driving on the highway.
