When turning left or accelerating from 20 mph there is a really bad hesitation. The car has a hard time accelerating. It didn’t have this problem when we bought it. This poses a safety issue because you really have to give your self a lot of space or you will get hit for not accelerating. Every other time the car is quick and responsive.

I have owned the car for 5 months. But have had the ability to drive it for four and a half of them. This vehicle has put me and my family at serious risk multiple time. The first incident my car would not accelerate when I drove onto the highway and it would constantly stutter when I would attempt to accelerate again causing a truck to almost rear end us. The following day my vehicle had a hot engine temp. I pulled over on the highway to an empty antifreeze tank. Refilled it multiple times to only have it empty out and completely shut off while we were driving! Took it to the dealership where it took them 2 weeks to return it. When I asked what the problem was they said they don't know they just replaced it. 3 weeks later ( 5/28/22) while driving back from an event the car starts making a clunking sound and shuts off on me 3 times on my way home with my 9 and 7 year old in the back. Thank goodness it wasn't on the highway! It's now 6/1/22 and I still haven't heard anything about my vehicle! This death box has put my family at risk 5 times. I would strongly advise against buying it! The manufacturer could care less. Luckily the lemon law protects them against people who's lives are constantly put at risk while driving there vehicle!

I was in a turning lane & a driver swerved in front of me. My car is equipped with auto start stop and it was on. I slammed on my brakes and the engine turned off. When I tried to start restart the car there was a fluttering/grinding noise. Turned off the key and restarted the car. Dangerous in the intersection with a stalled car. At the dealer now but not optimistic. Annoying to have to turn off feature each time.

The car will accelerate, but not beyond a speed of 20 - 30 MPH. The issue is intermittent, one happens in January 2022 and another one happens in Feb 2022. The issue happens after parking overnight, and the issue will go away after restarting the car. No-fault light shows up. The problem has not been reproduced by a dealer since it is intermittent. The issue is reported to the manufacturer, but no actions from the manufacturer have been taken. The issue does pose a safety risk to me and other road traffics since the problem may happen anytime on driving.

At highway speed engine began stumbling and shaking car and stalled the car within 5 seconds bring car to halt. Engine would not restart properly, would not settle at idle rpm with rapidly inconsistent rpm shaking the car and then stall within 5 seconds. Any attempt to place car in drive immediately stalls car. After attempting 50-60 bump starts to get car off road the check engine light and error message about engine control system error eventually showed. Hyundai towing refused to take inoperable car to dealership for warranty repair of 1000mi car, instead left it at our apt parking lot. The engine failure left the driver and other motorists in danger as unable to move stranded car off 50mph busy main road on cold dark snowy evening. Dealer reports they are “swamped” with repairs and cannot see an inoperable car for at least 2-3 weeks and no loaners or rental could be provided. There were no warning lights or warning during initial stall or subsequent restarts. Error message and check engine light did not light until attempting 50-60 bump starts trying to get car off road and a hazard to occupants and other motorists.

Before even reaching 3,000 miles, the engine in this brand new vehicle overheated in very normal driving conditions (under 80 mph on straight, flat interstate in 60-70 degree sunny weather). The dealership technician determined that the engine overheated and the water pump was severely damaged due to the compressor bolts not being tightened correctly during the manufacturing process at the factory.

Dear all, I bought the 2022 Hyundai Tusan SUV on June 16th, 2021. Since then, the car engine has been turn off more than 20 times, causing problems that require restarting. When I stop at the traffic light while driving and start, the car will turn off and I have to take off my car key and wait in 30 seconds and turn on the car again. Nowadays, The brakes were not applied because the engine was turned off while driving. At that time, my driving speed was around 15mph because I exited from a HWY. I think the engine issue is occurred when the engine rpm is low. I took a video of the engine turn off issue. Thank you,
