2022 Hyundai Santa Fe

The contact owns a 2022 Hyundai Santa Fe. The contact stated that on two occasions while driving at approximately 25 MPH, the vehicle lost motive power. On the second occasion, the vehicle was steered to the side of the road and restarted. The vehicle was taken to a dealer where the failure was not able to be replicated. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.

On November 28 2023, I was pulling onto a small highway when an alarm went off, car stopped (engine off) as other cars were coming towards me. The message displayed was "autostop is off. Shift to P or N and start engine manually". Because the alarm was so loud and I was concerned, I snapped a picture which will be attached. I immediately pushed start button and was able to get out of the way. I had not turned the Idle Start Stop (ISS) button to off - so supposedly it was on. (You have to push this button to turn ISS off. This happened twice until I was able to get to service department. After much time (and using a loaner car) Hyundai agreed to provide a new battery because of its health. This happened again. I took the car back and the manager showed me a technical service bulletin - regarding my car - "Rough Shift and Hesitation Improved Logic". This didn't sound like Idle Start Stop bulletin but I was assured it was (attached). Though the stall has not occurred since, the ISS icon at times just isn't there. My dealer is communicating with Hyundai to try to keep my car again and provide a loaner. I am reporting this because many others on Hyundai Forums are describing the same incidents. Yet I haven't seen anyone mention the Technical Service Bulletin, even though many have taken this problem to their dealer. To me this needs to be considered for a recall. I had a daughter and grand daughter in my car and had no idea what to do with cars approaching. Fortunately, just pushing start worked. I have read the manual and know what is required for ISS to work. All requirements were net. It is possible the TSB has fixed stall issue so I am mainly reporting for other drivers.

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.

On Monday nite returning Tuesday Morning I was coming home from work and I noticed my engine light is on and car is not running properly. I had to drive slower than normal at 12:30 AM I can usually drive the expressway but I am glad I didn’t .I live in Detroit Mi My employer which is Amazon is located in Romulus Michigan so I took [XXX] to [XXX] that when I notice my automobile was not driving as usual so I pull over and I notice my check engine light was on so I restarted my car several and it still was on so I Prayed and drove slow all the way home Thank God I made safely my auto have 7100 miles on it I had one oil change the next one is due at 10,000 miles. So the next morning I was at dealership when it opened and met with the manager at Lafountain Hyundai on Telegraph in Dearborn Mi He tried to diagnose my car and showed but it didn’t work so he told me to take it to Lafountain Dealership in Livonia I arrived and they told me their were backed for three weeks And couldn’t get a appt and when I do I will have to leave like everyone else and I saw all those cars mine just sitting so I ask the reception and she had no answer after I explain so I tried Hyundai Corporate office no answer so I been read all the trouble shooting information but that wouldn’t help because is slipping so I came home and back on the internet and began reading other comment.

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.
