September 2020 the car would not start after sitting for awhile, I recently had replaced the battery. Once I got the car to start, when. I slowed the car cut off while I was on a busy street, it's not the alternator everything was still on in the car. The check engine light appeared before the car cut off. Got started again, was able to drive. I've replaced fuel pump, cam shaft sensors, new battery. Any time I drive it the car cuts out when I am at a stop light, the car loses power while driving on the highway, and have to change the oil more often than 3000 miles. I find that I have to top my oil monthly. My check engine comes on randomly and goes off randomly. When I took the car to Hyundai regarding the check engine light, they stated it was a sensor issue.
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?.
Was driving down the interstate and went to get off on an exit and pressed the brake to slow down and pressed the clutch in to start gearing down and as soon as I pressed the clutch something broke in the clutch and it would not engage anymore. I coasted over to the side of the off ramp and cut the car off. Roadside assistance came out and towed my car to Hyundai of decatur. My car sat for three days before they would even pull it in. When they finally did, they didn't even get permission from the owner to tear the engine down. All he did was take off the valve cover and automatically tried to blame the engine being locked up on it having low oil which it did not considering it had an oil change on the 20th of June and the car broke down on the 29th. The mechanic did not even look at where the problem originated. Oh, and no check engine light or low oil light came on so that tells me that it has nothing to do with the oil. It tells me that there was faulty parts in the clutch and now they are trying every way they possibly can to get out of repairing my car under the warranty. So if you could please do all you can to get this out there that Hyundai of decatur are hateful and treat their customers like trash and don't abide by their warranties. I advise anyone to never purchase a car from them ever.
