Bought my car in 2021 and had actuators for windows replaced, now in 2023 I need passenger actuator replaced again. My heater is stuck on 4 and continuously blows and cant be turned off. The summer was ok but wasted gas because I had to have the air conditioner on or else eventually nothing but heat will blow out and so its not in my face the air has to blown in "feet" only mode and eventually starts to really burn while I'm driving. No coverage cause its considered "cosmetic" even though the whole panel needs to be replaced not just the knob. My car is also apart of the Hyundai recall #251 but when calling my local dealership they told me I had no remedy for any type of recall so that ment I had no recall. I called Hyundai Customer Service and asked about the notice to dealers, the notice lets dealers know that owners of effected vehicles are eligible for substitute transportation if they do not want to continue driving their car. I let him know what my local dealer told me, and how she didn't even let me know about the recall or the alternate transportation choice that's available to me and he just told me that they know about the recall so they should help just ask for a manager next time. I have my check engine light on now after hearing a ticking noise like other complaints, hot air constantly blowing and now I have to worry that whatever is wrong could also effect the problem that is considered to be likely to cause my car to catch fire! Please let dealers know just cause there's no remedy yet for the recall, please at least let people be aware that they are at risk of having their car catch on fire especially when they call and ask specifically for the information!

Engine has been causing a knock of some sort making the check engine light to constantly come on. Engine is the same engine as the Kia soul and those engines have a full recall to be replaced, the recall needs too be extended too the Hyundai accents. The engine began making the issue before 70 thousand miles as all mechanics only saying it's just a sensor when I the driver can hear a klack when driving after a half hour.

Customer states that there is a rattling noise upon start up. It is more noticeable when the engine is cold, upon starting. Customer states that the noise can be heard in speeds lower then 40 MPH. We have not serviced this vehicle in over a year and the vehicle has gone 25,000 miles since that time. Customer states that she recently went to the hyundai dealership complaining about this noise (rattling noise which is louder when starting the engine when cold). The dealership looked it over and said that there is nothing wrong with the engine. She again told them that this noise is noticeable to her. The dealership again told her that they did not find any fault with the engine.when started first thing in the morning has a knocking noise sounds like piston slap. Remove all spark plugs and bore scope cylinders and found that # 3 cylinder walls have heavy cylinder wall scarring and oil is on the top of the piston (see pictures) .engine is damaged and will need to be rebuilt or replaced.oil looks clean.

Spark knock due to timing error in ecu dealership needs to send recall notice to do free update

Knock sensor messed up and is causing the crank sensor to mess up also. My car will die in the middle of the road while drive and it's very dangerous. It will take roughly 15 minutes to start sometimes.

Once I am driving on the highway the car seems to loose power almost like if the car wants to shut off the rmp goes low then the check engine light has turned on. I have taken it for its service on time and no issues but the good year rep told me the error code they received was p0326 which is the knock sensor and now the engine light went away but it has happened twice so far within the last two months.

As I go up a hill or rapidly accelerate on an incline the check engine light will come on. The problem points to the knock sensor (code p0326) being at fault. This does not happen often but when it does it is disconcerting. I replaced the knock sensor with a new oem part, but it too acts the same as the old one. I called the dealer and they want to charge me $90 to diagnose the problem and then any labor/parts needed to repair it. However, I have read several reports online about a software update, flashing the ecu has fixed the problem. If this is so, shouldn't this be a reason for a recall?

I notice my car had a 'knocking'/ 'pinging' sound and took it to the dealer to get serviced about 7 months ago. The dealer claimed they 'couldn't replicate the noise' which is false because I took one of the service representatives for a ride to show him the noise. They decided to clean the intake which helped, but the pre detonations are back again, this time they are more noticeable. I've read several accent owners in forums complaining about pinging, knocking, and pre detonations. Hyundai must act on this issue!
