2022 HYUNDAI SONATA Complaints

In November of 2024, I had a Check Engine Light for a Cylinder 2 misfire and a fuel to air mixture ratio. Had it towed to a Hyundai Dealership. Got a call the next day saying it was fixed. Picked the car up and 50 miles later it popped back up. Had it towed back again. They said my fuel injector was cracked. They had to order the fuel injector directly from Korea. Took 5 days to get the part and it installed. Fast forward to September 2025, Cylinder 2 misfire showed up again(same cylinder the fuel injector was replaced) and now the car shakes violently when accelerating and stalled at a stop light. Massive safety concern due to risk of an accident. Car to be towed to another dealership for the same issue less than a year apart.

Vehicle will not start. This is the fourth incident where vehicle will not start. It has had the software update, battery and voltage regulator replaced in the summer of 2025. In Aug of 2025, vehicle will not start with jump or use of 12v battery in vehicle.

Car is a Sonata Hybrid Limited equipped with a solar roof which charges the hybrid battery. Vehicle began to cut off battery power while parked, requiring the use of a factory equipped 12V override switch in March 2025 after approximately 3.5 years of ownership. This occurred multiple times, often when the car was parked in the sun but independent of how long it had been driven prior or how long it had sat without being started. Evaluated by two Hyundai dealers; second dealer found a fault in the "solar DCDC converter" as well as the hybrid battery bulging. Battery module replaced. Unclear if this resolves the issue or it will recur again. Am speaking to Hyundai regarding battery warranty extension as vehicle had 88000 miles on it at the time of the issue starting. Online fora (e.g., Reddit, Facebook) note other customers who have had similar problems with similar fixes. - [XXX] - [XXX] - [XXX] - one individual in this thread had complete power loss while driving down the highway This issue potentially risks stranding customers, and if the hybrid battery continues to bulge increases the risk of fire which could lead to property damage, personal injury, or death.

Fuel Lines and Connections / Fuel Tank Band / Fuel Tank Vapor Vent System Hoses [XXX]: My check engine light illuminated. I immediately returned to Hyundai Riverdale. They advised me it could be the fuel tank and stated they needed to keep the car for 5-7 business days. May 1, 2025: I dropped off my car for inspection, having made arrangements for a personal rental car. May 7, 2025: I received a text message (no phone call) indicating the inspection was complete and was presented with a $3500 bill to replace the entire fuel tank. May 9 or 12, 2025: Marilyn from Hyundai Riverdale called me regarding my vehicle. She explicitly suggested I "contact your insurance company, advise them you hit something on the road, pay the deductible, and they will pay for the repairs." She then stated, "I know you hit something after April 9th because your fuel tank is now damaged." I denied hitting anything. During this call, she mentioned a "RECALL" related to fuel tanks on all Hyundai Sonatas, which I was never previously made aware of. I questioned why I was being charged if there was a recall for the exact issue I was experiencing. She claimed my car was previously checked and the fuel tank was fine, therefore the cost fell to me. May 14, 2025: Merilyn called to inquire if my insurance would cover the repairs. I informed her I was picking up my vehicle as another Hyundai dealership in Newnan was willing to perform the recall repairs for free. Upon arrival at Riverdale, I faced resistance but demanded my car be released. I was then charged a $200 inspection fee, which I refused to pay. Marilyn then provided my keys and, upon learning I planned to drive to Newnan, stated, "I wouldn't feel right letting you drive this car off the lot and something happening to you. Your vehicle at any moment can blow up due to the fuel tank. It's very dangerous to drive and suggest you get a tow truck." April 11-May 1st I drove that vehicle w/no idea it had the potential to blow up. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

Driving on the highway ih35N at 75 mph, my car's engine randomly started violently jerking and then shut off and wouldn't start back up. Had it towed to Hyundai (2022 Hyundai Sonata ~33k miles) took a few days but they repaired it under warranty saying it was bad fuel injectors and they replaced all 4. My car just dying on the highway could of caused a bad accident at that speed. Moving to present day (June 28th, 2025) car is at 56,400 miles and its starting to jerk at low speeds and is getting terrible gas mileage again. I'm taking it back in as I am still under warranty but everything points to fuel injectors again. Only warning lights I get was when the car died on the highway. Just a check engine light.

First owner, sporadic acceleration problems reported from approx 6k miles. Documented with dealership.. “couldn’t reproduce” issue every time I brought it in after an occurrence. Dangerous when entering highway, as I never knew when it would fail/stall. Eventually broke down on busy interstate highway, replaced 1 fuel injector, and guilt tripped me into “needing” to have fuel injector cleaning because the others might fail as well. 27k miles was the first breakdown. 38k was the second breakdown and almost caused a serious accident when I was unable to accelerate. Replacing all 4 fuel injectors but not covering the oil change due to their faulty fuel injectors.

I was driving my yesterday morning like normal, about 15mph getting off of a freeway offramp, when all of the sudden I heard a strange brief noise come from the inside of the car. I couldn't figure it out so I drove home. Went inside for about 20 minutes, went back outside to leave again and I noticed my panoramic sunroof had shattered/exploded from the inside outward. I had it towed to my local dealer in hopes warranty would cove, but I was told it wouldn't. I have to use aftermarket glass with my insurance company to replace it due to Geico not covering OEM glass.

Car keeps jerking also it’s something going on with the fuel injections I’ve had to get them replaced twice. Please help

Purchased vehicle on March 5, 2025 from a dealer. At the time it had approximately 20,000 miles. Within days of purchase, the car would not start even after pushing the battery reset button. Eventually, it would restart, but the time it took was considerable. Took the car to the Hyundai dealer near me and discovered that it had been with them for two months prior to purchase for the same problem. They have replaced the 12 V battery and possibly the hybrid battery, but now after owning it for about six weeks, it is giving me a message that there is a problem with the hybrid system and I should stop driving immediately. It is now back at the dealer. They can’t seem to duplicate the problem and I don’t feel safe driving the car because I don’t know if and when I’m going to get to my destination.
