2022 HYUNDAI SANTA FE Complaints

3 different times in last 3 weeks the car seems to lose power while I’m driving. It will not go above 35-40mph even though I’m trying to accelerate. No warning messages. I had to go slow with my hazards on until it eventually slowly returns to speed. Very scary on the highway.

ON MULTIPLE OCCASIONS WHILE DRIVING ON THE HIGHWAY USING CRUISE CONTROL, THE AUTOMATIC EMERGENCY BRAKING HAS ENGAGED FOR NO APPARENT REASON. A WARNING FLASHES ON THE DASHBOARD AND THE CAR SLOWS DOWN VERY SUDDENLY. IT HAPPENS FOR ONLY ABOUT 2 SECONDS THEN GOES BACK TO NORMAL. I HAVE OWNED THE CAR FOR ABOUT 2 WEEKS AND IT HAS HAPPENED AT LEAST 3 TIMES.

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.

Loss of power from gas engine at speed car failed over to electric motor at 70 mph on highway unexpectedly and car did not have enough power to maintain speed.

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.

While driving on the freeway, another vehicle passed me in the lane to the right of me. Right before it passed me, my car triggered automatic emergency braking for no reason. It was very terrifying. The other car was in its own lane the entire time. This has happened multiple times.

on 11/20/23, Car refusing to accelerate past 30 and not shifting thru the normal gear sequence Engine revving up to 3000 rpms and hesitating to go past 35 or 40 mph Auto start light is lit the entire time in bright amber on the dash of the car Pressed the auto start button and it would not disengage

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.
