2017 HYUNDAI SONATA Complaints

Sun roof flew off while driving, the metal framing was twisted and dent. Sun Roof was closed at the time. Pictures were sent to insurance company but no one has looked at it yet. No warning. Sun roof was working properly.

I have a 2017 hyundai sonata sport,it started using a lot of oil,one day I was driving and it just lost speed and the car just started jerking. I checked the spark plugs and oil had gotten on them. I changed the spark plugs,drove it for about 2 weeks and it did it again. I was constantly having to put oil it and changing the spark plugs every 2 weeks. The check engine light would come on every time this happened. I took it to a hyundai dealership they first wanted to do a oil test which they realized would not work because it was using to much oil ,second they wanted to do some other test that would cost almost $300 dollars which would still not determine if I would be eligible for the recall. Can i get some help please,please

Here is your updated review with that included: ? I am very disappointed with Hyundai Motor America and the service I received at Hyundai of Renton. I own a 2017 Hyundai Sonata and received a letter about a required software update and ignition cylinder protector due to known theft issues. I went to the Renton dealer for the recall service. They performed the software update and were supposed to install the ignition cylinder protector. Unfortunately, my car was later stolen because of this exact issue. The ignition was damaged during the theft, and I had to replace it myself just so I could drive the car. When I returned to the dealer, they refused to install the ignition cylinder protector, saying the ignition was broken. It was broken because of the theft — which happened due to Hyundai’s known defect. After the recall software update, my key fob also stopped working properly. I went back to the dealership, and they refused to fix or properly reprogram my key fob. On top of that, the service manager, John, was very rude and unprofessional. This has been the worst experience I’ve had with a vehicle and a dealership. Because of this situation. Very disappointed.

While driving around 45 mph, the steering wheel locked up and car came to a hard stop. Luckily cars swerved to avoid me. This was the second time it happened. The first time I was in a parking garage and the steering wheel locked up. After restarting the vehicle, the steering wheel worked again. The dash showed no fault codes or engine light. I found out there is a service bulletin and took it in to the dealer. Once there, the confirmed it was the power steering and is covered by the service bulletin and extended warranty. However, because the bulletin requires the dealer to clear code to try and reproduce it, I have to pick up vehicle because they could not reproduce the fault code. So now I have to drive the vehicle knowing their is a service bulletin for the problem and have it happen again before it is fixed. There is an extremely high likelihood of injury considering you lose all power at wheel and car continues to move.

My 2017 Hyundai Sonata Hybrid has a permanent and recurring DTC P1326 (Knock signal range/performance) from the Knock Sensor Detection System (KSDS), indicating potential connecting rod bearing wear in the Nu 2.0L engine. The vehicle enters limp mode (reduced power, limited acceleration/speed) on the highway under load, with hard engine vibration, tinkling/knocking noise from under hood, and significantly reduced MPG. These symptoms create a serious safety risk: sudden loss of power at highway speeds (e.g., 50+ mph) makes it difficult to maintain speed, merge, or avoid hazards, increasing crash risk or stranding in traffic. In rare cases, bearing wear can lead to engine seizure or failure. The problem first appeared summer 2024 at approximately 115,000 miles. The Check Engine Light illuminates (cristmass tree), and limp mode triggers during highway driving. I have an OBD scan showing confirmed, pending, and permanent P1326, plus related hybrid communication codes (U0293, U1004) likely secondary to the protection mode. The vehicle has been inspected multiple times (four visits) by a Hyundai dealer. Each time they scanned the code, performed basic checks, but stated “engine is working normal, no road vibration, nothing” and did not resolve the issue. The code returns immediately after clearing. I replaced the knock sensor, engine mounts, spark plugs, ignition coils myself—did not fix it. Dealers did not perform the full bearing clearance test or follow TSB 22-01-023H (Service Campaign T6G) procedure as required for this known issue (related to Recall 209 and Campaign 966). The component (engine/connecting rod bearings) is still in the vehicle and available for inspection. No police, insurance, or other parties have inspected it beyond the dealer. This matches a widespread known defect in 2011–2019 Sonata Hybrids (bearing wear triggering P1326/limp mode).

This car is becoming more of a headache than it’s worth. Turned the car on, My car started shaking and my check engine light came on. then I got this message “A possible condition with your engine control system has been detected on a 2017 Hyundai Sonata”

My car stayed with up to date oil changes and everything. One day I noticed it was leaking oil and had to stay on top of adding oil. When took to a mechanic they said my motor was blown and needed a new one. I took very good care of this car and it’s crazy that I need a new motor after babying the car.

Was just driving and lost steering, basically very hard to turn the wheel. Traction control light and a red steering wheel light came on.

My 2017 Hyundai Sonata is exhibiting a severe metallic knocking noise and metal debris in the engine oil—primary indicators of the Theta II engine defect (NHTSA Campaign 17V578). These symptoms indicate imminent engine failure, posing a significant stall and crash risk. On or around 8/20/25, I took the vehicle to Earnhardt Hyundai-San Tan. I informed the technician of the oil burning and metal shavings. They refused to perform the recall repair and charged a $200 diagnostic fee for an inspection related to a federally mandated safety recall. Under federal law (49 U.S.C. Chapter 301), recall remedies must be provided at no cost to the owner. Furthermore, components were not reassembled correctly during the inspection. The vehicle is now leaking oil onto my driveway and has been rendered inoperable. It has not been driven since I picked it up on August 25, 2025. I am requesting that Hyundai be compelled to perform the recall remedy and reimburse the unauthorized diagnostic fee.

The 2017 Hyundai Sonata has had an ongoing engine malfunction defect that is causing engine knocking, stalling, and smell and rapid depletion of oil. The continuous issues are concerning especially when the car is not driven on a regular basis as it is utilized as a second vehicle. This has been a noticeable issue for quite sometime now. I have taken the car to the Hyundai dealership on multiple occassions after notably heavy oil consumption in a short time period in between scheduled oil changes. I am told by the dealership that it is evident that the engine is rapidly processing and burning oil inappropriately from a possible manufacturing defect recall related to connecting-rod bearing failure that was issued by Hyundai for various Hyundai models. The damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of fire.
