2022 Hyundai Santa Fe

My vehicle has been having intermittent cylinder misfires for about 4-5 months now. Initially, before I knew this was the issue, I didn't think much of it because the shaking that would occur was mild, but as it gradually worsened I knew there was a bigger issue. I will start my car, the check engine light will be on, and the car will shake very hard with acceleration throughout the entire drive. I know that it is a cylinder misfire because I will get an alert on MyHyundai app telling me that a DTC code has been detected, this is the code, "DTC P030100" (the servicing department confirmed this was the misfire code). I have come to learn that the car usually only populates the code when the issue occurs for consecutive trips. As this is an intermittent issue, there are times when I know that the car is misfiring during the drive (it is obvious), but I will not be sent a DTC notification. I have taken my car to the dealership 3 times for this issue with documented DTC codes for each visit. Upon my initial visit to get this seen about, my local Hyundai dealership changed the spark plugs and coil packs in an attempt to fix the issue (although the spark plugs should not usually need replacing at 20,000 miles). It was about 2 days until it started misfiring again. Since then, I have taken it back to the dealership twice because of this unresolved issue, but if the cylinders are not misfiring the day I take it, the issue is dismissed. I truly do not think they know or care to investigate the matter further. I have taken it to the dealership 3 times within the last 3 weeks regarding this issue. I have to imagine this is a safety issue as it can increase the chance of engine failure. Today was the 3rd visit, I picked it up and as I was told, "we saw the DTC code, but the cylinder was not misfiring when we looked at it, so we drove it around a good bit and no issues so the code was cleared".

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The check engine warning light was illuminated. In addition, the blue link feature failed to contact Law Enforcement as needed. The vehicle was towed to the dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 55,777.

On Friday 10/28/2022, I took my vehicle to receive its first oil change at a third party location at 7,042 miles and was told by the mechanic that there was significant metal pieces in the oil filter, which was abnormal for a brand new car but I was told it should be okay so I continued driving the car. My family and I left on a 700 mile road trip the next morning and by that night, the engine began making a knocking noise. On Sunday morning 10/30/2022, the engine would not accelerate anymore. On Tuesday 11/01/2022, I took the vehicle to Sport Durst Hyundai in Durham, NC who informed me the engine has failed but it would not be covered under warranty because they do not deem this to be a manufacturers defect. The car is not drivable and Hyundai is unwilling to replace the engine on a car with less than 8,000 miles on it. There is no reason my engine should have failed on a brand new car.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that on multiple occasions while driving approximately 25-40 MPH, the RPM increased to 5,000 however, the vehicle failed to respond. The contact was turned off and restarted the vehicle. No warning lights were illuminated. The contact called the local dealer and was advised to schedule an appointment to have the vehicle diagnosed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000.

We have had already had two issues with our Hyundai Santa Fe that we purchased new from a dealer on 5/21.The first malfunction happened on 7/23. While driving, we had several messages come across the dashboard warning that some sensors were not working properly. We then had the warning light, front collision light, the traction control light, the abs light, the auto hold and the emergency brake all light on the dash. We also lost the blind spot sensor on the side mirrors. Called the dealer and took the car in. Two days later was told it was a wheel sensor and all should be good. Then on 8/31, while merging onto a highway, I pressed the accelerator and although the engine revved, the car did not increase in speed. Luckily the car behind me was able to swing around me and I put on my hazards and pulled to side of the road. I turned the car off, restarted it and pulled out. Five miles down the road, while in traffic, the same issue occurred, but after about thirty seconds or so, the car jerked and picked up speed, Back to the dealer it goes and they called to tell me that they cannot replicate it and there are no diagnostic codes showing. They are going to keep it for a few more days to do some more diagnostic testing, but don't know what the issue is. This is a brand new car -

We have a 2022 Hyundai Santa Fe with less than 17,000 miles. We pulled into the left turn lane at an intersection. When we stopped for a red light, the vehicle abruptly shut down all power with no warning. We tried to restart the car and nothing would work. We tried the hazard warning flashers and they did not work. Our vehicle was completely dead with no dash lights, no infotainment screen, we could not put the car in park or drive. We could not activate the emergency brake. It was as if the battery was disconnected. We were sitting in the travel lane of a very busy multi-lane roadway with no way to exit the vehicle unless we allowed it to become an errant vehicle. If my husband took his foot off the brake, the vehicle would have rolled backwards down the hill where we were stopped. After several light cycles, we were able to get a break in traffic and he was able to let the vehicle roll backwards and steer the car into a small roadside parking lot. I was able to find someone in an adjacent business who gave us a wooden chock to put under the tire so he could take his foot off the brake and prevent the car from reentering back into traffic. We called Roadside Assistance and tried unsuccessfully to restart the vehicle numerous times over the 2 1/2 hours while we were waiting for the tow truck. The tow truck driver came and was able to jump start the vehicle. This has now happened a total of 4 times in the last 4 months. The dealerships can not recreate the problem and there are no diagnostic codes because the vehicle dies abruptly. Hyundai Customer Service refuses to do anything to help with this issue because there are no codes and the tech can't recreate the issue. We can not drive this vehicle because when it happens it is very sudden and gives no warning. This could be a serious safety issue when the vehicle shuts down in the travel lane and we are unable to get out of the vehicle, activate emergency flashers or even put the car in park.
