2022 Hyundai Santa Fe

Ref NHTSA TRACKING # 11557625 Vehicle broke down again within 5K miles and 45 days of prior repair referenced in above case. Similar conditions, highway speed, bucking and vibrating, loss of speed control, no warning. Subsequent repair confirmed same issue (fuel injector) as original breakdown/repair and my initial notification to NHTSA.

Vehicle began to shake, buck and emit a grinding noise while traveling on highway resulting in loss of speed control and associated fear. Check engine light appeared simultaneously. No prior indication of a problem. Managed to limp to next exit via shoulder. Had car towed to dealer as warranty was still in effect. Problem was diagnosed as fuel injector failure and repaired. Learned it is a common, recurring issue with Hyundai 4 cylinder engine. Not unusual to have multiple failures per vehicle. Hyundai is only authorizing repair/replacement upon individual failures, not pre-emptive even though common and recurring. Confirmed this is a common, recurring issue across Hyundai via our local mechanic and internet info. Vehicle has now experienced a second failure and is being towed to dealer.

On 10/31 I loss power while on the freeway for the 2nd time since August. The car was assessed and fixed according to the dealership. My car threw a 2nd code which was cleared and not fixed due to not showing issues according to the dealership. I got my car back in mid November. I immediately complained that I still had a rough idle and was told my car was fine by the manager via service rep. On 11/28 my car loss power on the freeway again for the 3rd time since August. According to the codes, all my cylinders are failing one by one. This is a huge safety concern. The dealership could care less.

The issue with Hyundai 2.5 L turbocharged engines is getting a lot of exposure on-line. My story begins about a year ago with me complaining to the Hyundai service department about my 2022 Santa Fe Limited hesitating, lurching, and stalling (once) following acceleration from a complete stop, all without the Check Engine Light (CEL) illuminating (which the dealership said is needed to initiate troubleshooting). In addition, there is a common thread where dealerships are telling owners that it is "... probably bad gas." On 2 October 2023 the SUV started and was idling very rough, and as I drove off, the CEL illuminated (finally). After turning off the SUV for five minutes, it started fine with no CEL. My OBD-II code reader pulled three codes from the SUV that afternoon: P0300, P0301, and P0302 (Misfire - General, Misfire - Cylinder 1, and Misfire - Cylinder 2). The trouble codes should be sufficient for the service department to locate a problem, and to their credit I was placed in a loaner vehicle when I dropped the SUV off on 7 October 2023. So far (24 October), they have not identified a problem, even though there is a fuel injector Technical Service Bulletin (TSB) for multiple Hyundai vehicles (including my Make/Model/Year) that may or may not apply to my specific vehicle. Bottom line: The vehicle is unsafe to drive (as I told the service manager), has had this problem for approximately one year, and if the vehicle stalls when I am entering traffic it is not going to end well - not for me in a stalled vehicle and not for Hyundai after they had an opportunity to address the problem.

Vehicle check engine light came On while driving and vehicle began misfiring. Vehicle was in the shop and injector was found defective. Vehicle again had same issue but intermittently and wife would have to pull over and shut down the car to be able to drive it safely home. Dealership tried blaming bad gas which was purchased a mile from dealership. Within 50 miles vehicle began acting the exact same way and Hyundai dealership says injector needs replaced but blaming contamination not a known issue Hyundai has with injectors. Found multiple instances of same issue and same made up issue of contaminated gasoline even at the same dealership I went to. Faulty injectors make the vehicle unsafe when traveling at highway speeds on busy highways.

I have experienced a sudden loss of power when accelerating and then sudden vehicle slowdown and engine shutdown. Twice this occured at either hiway speed or accelerating to highway speeds. In both of these cases I easily could have caused or been involved in a serious crash. The third time happened on a city street and was not as egregious. There was no forewarning this might happen...no warning lights on the dash, etc. The vehicle is currently in a dealership service department after the last occurrence , and has been for five days with no knowledge of the current status. The prior times the dealership, Kolar Hyundai in Hermantown, Mn. has only cleared the error codes stored in the computer, but not identified a cause. The three times it was in the dealership were 2/15/22, 6/28/23, and 9/5/23. The second time it had to be towed in. The car currently has 9200 miles on the odometer. I am now afraid to drive it, as I consider the problem to be dangerous to my safety, as well as other vehicles. I have contacted Hyundai Customer Care, but received no response as of today.

I was driving the vehicle my pregnant wife and 1 year old baby were in the car with me. Car started shaking and i was loosing speed right before getting off the freeway. There was a very strong smell of gas as if it was leaking but it was not. I have an appointment to be checked at the dealership Wednesday August 16th. This is the second time something like this happens while driving in the freeway.

I had previously filed a complaint and received an issue number 11494975 I have not been able to retrieve any information related to this number. In any event I am constantly having problems with acceleration, stalling, the car puts itself in Neutral, and on occasion has completely turned itself off at a light or while driving. I do have a video of the acceleration problem and revived an email back from Laura Nelson. This is a very serious safety issue. Hyundai is not responding to following up. I also took it to an outside mechanic to put in the computer and got a general code so there is a problem somewhere. Thank you Susan Piller

I have experienced power loss soon after I bought the car in Dec 2021. While I was driving the car was going in a constant speed of 20 to 30 mph. However hard I pressed the gas, car felt not responsive. Reported this to the service center and was advised that this may be since car is learning my driving habit. Later in december 2022, received a recall 236 letter from hyundai which was mentioning an issue similar to the one I experienced. Took the car for recall and informed me that the software upgrade is done as per manufacturer recommendations. Now on March 28th 2023 while I took the car out in the morning, there was more smoke than usual. And the same issue happened again. The car was not going beyond 20 to 30 mph for around 6 miles. Reported the same to the nearest service center and booked an appointment after 2 weeks . Also sent a complaint to hyundai motors directly
