Hyundai Accent hesitation problems

Filed Sep 30, 2026 · Engine, Lights · FL

Transmission began exhibiting hesitation, RPM surge/drop, and a stuck gear at approximately 26,000 miles. Diagnostic trouble code P0741 was confirmed by the dealer, and the transmission assembly was replaced under warranty. This matches a documented defect pattern currently under federal class action litigation involving this manufacturer's IVT/CVT transmissions in this and related models (2020+ model years), specifically sudden loss of power and acceleration failure. Prior to the repair, the issue was reported verbally to a service advisor but not logged on the invoice. Separately, at the same service location, a coolant reservoir was found completely empty within hours of a repair visit where the dealer stated it could not reproduce a related stuttering complaint during a road test, and no diagnostic codes were stored. A rear brake light has also remained inoperative across two dealer visits without being flagged, and was later found by a third party to require dealer-specific tooling to access — confirming it was not a simple user fix. The vehicle remains drivable but the transmission defect poses an ongoing safety risk given its documented tendency toward sudden power loss in this defect pattern.

I've had nothing but trouble since I purchased this vehicle. I bought this car in oct. 2014 and it had over 89,000 miles on it. Two months after receiving this vehicle, I took it to midas to have the oil changed. The mechanic informed me that there was some type of corrosion coming from the oil chamber. He flushed it out and changed the oil. After driving the car for two more months, I noticed some hesitation while excellerating. I had a mechanic look at the car and he told me I needed to change my spark plugs and wires, which I did. Approximately two weeks later, the car started hesitating again. This time it would not go any faster than five MPH. I had to have this car towed home. This vehicle was financed for $10,023 and I'm on a fixed income. I had already made car payments totalling over $3000. I was informed that this car has internal engine damage. Diagnosis: 2 bad cylinders and a melted catalytic converter. Price to repair: $2058. For the second time, I had to have this car towed to my home, and it has been sitting there ever since. I'm contemplating whether I should invest any more money in this car because I'm afraid that I'm going to continue having problems. Besides I don't have $2058 for another engine and converter. I received written notification this november that this particular vehicle per my VIN number is on the recall list. I have no way to take it in because it doesn't run. This has got to be the worse investment I've ever made in my life. I've notified the attorney general's office and the better business bureau of my experience with this car. I believe these cars should be taken off of the road due to the many hazards they pose. I will never buy another korean vehicle. For now on, I will only purchase american made cars if onlyfor safety reasons. Can I get a refund on this piece of junk?

I brought my car into the dealership at 33000 miles when it was bucking and hesitating when I accelerated. The mechanic could not detect a code and told me to drive the vehicle until the part completely broke down and a check engine light came on. The car soon would not accelerate past 25 MPH and was bucking up and down like a ping pong ball. I crawled into the dealership and was told I needed an ignition coil replaced. I was also told the other coils would probably go bad one by one, but I couldn't have them all replaced under the warranty at one time until they malfunctioned. I was very nervous driving the car until in december 2014 another coil started occasionally to act up. On some days the car will buck and hesitate for a few minutes, but the check engine light will not come on, so when I bring the car in to the dealership, they cannot find anything wrong and the problem cannot be duplicated. On other days the problem is very mild and only for a few seconds and still the check engine light does not come on. When I had the problem severely one day, I drove to another mechanic in a chain repair facility and they put the car on a master computer which detected a problem in the #4 ignition coil. They suggested I race over to the dealership to see if they could catch the problem also on their master computer, but they could not detect anything. I want the #4 ignition coil replaced under the warranty because I am a senior citizen and am very nervous driving my car around in this broken condition. The main problem is that the check engine light does not come on and there is no code stored. My daughter has the same problem with her 2011 hyundai accent. I hesitate driving my car the hour to visit my son for fear I will suddenly need a tow in an unfamiliar neighborhood. The number of complaints here for this same problem warrants a recall.
