Was driving on the highway while it was in cruise control and on several occasions when trying to accelerate the vehicle would jerk aggressively and struggle to accelerate. It did this about 3 times on my way to my destination. Took it in and they said they couldn-??t find anything wrong with it nor could they replicate the issue. No work was on done on it.

I was driving in the freeway and all of a sudden my engine power became week. I try to step accelerator but it did not cooperate.

- Ewa Beach, HI, USA

Loss of acceleration while driving. This has occurred multiple times (always while moving or actively driving). The first time we were driving up a significant hill and the car slowed, lost power and we had to pull over and coast back down the mountain to a repair center. The second time, I was on the freeway and lost acceleration causing me to pull off the road in median. The third time, I was at a stoplight and when the light turned green, I had almost no movement after edging into the intersection. Eventually, at about 5 mph, the car regained speed. The check light went on in the first event and the car was supposedly repaired at the second dealership by re-tensioning "pins". However, no lights or warnings went on for incident #2 or #3 that occurred after the earlier repair effort. The vehicle is currently at the dealership service center for it's 7th day of "unable to replicate the problem" after incident #3.

The car was idling for about 30 mins as I waited for delivery of groceries at curbside pickup. I put the car in drive but the motor did not kick on. I was able to drive on electrical power until the hybrid battery died. I lost complete power in the middle of the Interstate but I was able to coast to the shoulder. I had a check engine light and other warning lights on the dashboard but they went away when I restarted the car

The car has been taken to the dealer multiple times for not accelerating out of 1st gear when starting up, and also for shuddering at high speeds. We have been stranded, hundreds of miles from home on 2 occasions, first with less than 30,000 miles because the spark plugs needed to be replaced. And the second occasion, also hundreds of miles from home, because the car failed on the highway and limped into a dealership, where one of the fuel injectors was replaced at approx 50,000 miles. The mechanic at this dealership voiced his concerns that these were the original fuel injectors, He said he was aware of the problem, but was only permitted to replace one of the fuel injectors. The car continues to shudder at occasionally, and refuses to shift out of 1st gear at odd times. We have tried to get Hyundai to replace the fuel injectors, but they refuse. I would like this to be serve as a record of our problems so that others can be aware of a problem that exists with these cars. This is a safety issue, as if the car will not accelerate on a highway or crossing a road, it is possible to have an accident. Also, having the car fail on a remote highway is also a safety issue.

While Driving home from work, the 2022 Hyundai Santa Fe Hybrid Vehicle's, Hybrid battery began to discharge rapidly, the Gasoline Engine did not start to charge the system, within 1/4 mile the Hybrid Battery fully discharged, and the Vehicle lost all acceleration, the Dash warning " CHECK HYBRID SYSTEM, STOP SAFELY " came on along with a loud audible warning beeping. I pulled off the road as soon as possiable. The Vehicle would not accelerate, and the gasoline engine part would not start. Several other warning lights illuminated, including the 12V battery low warning. I turned the Santa Fe off, and called Hyundai Roadside Assistance. While on the Phone with the assistant, as it was Night time, I couldn't see to check the VIN number for her I turned on the interior lights, then continued talking to the assistant. I attempted to restart the Vehicle, and it started the Gasoline Engine this time, we talked, and she suggested I see if the Hybrid Battery would now charge it's self, which it very slowly did up to 1/8 full, then I attempted to move the Vehicle to a safer location, a Gas station parking lot. I was able to drive the short 1/4 mile to the parking lot, but the vehicle had very little acceleration. Almost no power! At the parking lot I attempted to rev the engine to get more power to the Hybrid Battery, while waiting for a Tow Truck.

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.

- Columbia, MD, USA

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

2022 Hyundai Santa Fe Hybrid. This incident has occurred twice at the time of this write up. Both incidents have happened on the first start up of the vehicle engine for the day in the early morning (on the way to work). The temperature outside was cool (10-35 degrees, Maine). On at least one occasion it had rained during the night before using the vehicle. It may have been damp on the other occasion as well. After about 3 miles of driving the vehicle it completely loses power. No amount of movement to the accelerator changes the sudden loss of all power. This is a hybrid and the battery gauge below charge/economy/power rpm area of the vehicle starts to completely and instantaneously drain to what would be zero had I not been able to pull the vehicle over and turn the vehicle off. At this point, on both occasions, leaving the vehicle turned off for a minute and then restarting the vehicle seems to alleviate the problem. The incidents have occurred about 2 months apart and since the vehicle turned 20,000 miles. I also feel like it takes more push on the accelerator to get the same response that I got on day 1 when I drove it off of the lot at the dealership. I also notice that the EV indicator light does not come on as frequently as it used to. It would always come on when coasting - and now sometimes it does not.

On Friday the 7th of April while driving about 40 miles/hr my car lost power in traffic. I pushed gas pedal all way to floor to no avail. Then I was able to get it to move at about 20m/hr for short distance and it cut out and engine lite on as well as a horrible smell like something was burning. It had to be towed into dealer.

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
