2022 Hyundai Santa Cruz problems

“Vehicle intermittently drops into a “Limp Mode” while driving. Speed becomes restricted at 20 mph and engine RPM locks at 2000 RPM. Cannot accelerate when pressing on gas pedal. No engine lights come on when this occurs. Turning ignition off and restarting temporarily resets the computer and clears speed cap. Has happened 4 times since purchased. Has strong coolant smell and occasionally rotten egg smell. This is a safety hazard! Dealership has offered no solution other than if it happens again to pull over, call tow truck, leave car running and get it to them. Opened complaint with corporate. No help. I am afraid to drive my car. This could cause a major accident and harm myself or others. Asked dealership if they could contact an engineer and was told no.”

“I have had one Transmission and the tow hitch wiring harness replaced once from recalls. The tow hitch wiring harness is failing and all the warning lights are failing. The transmission is slipping upon takeoff and will rev at elevated RMS on the highway at times. When in reverse it will still move forward at times and on a hill it rolls back. The breaks have slammed on (for no reason) a couple of times while on the highway. It has also lost power. No check engine lights are on at this time. The warning lights for wiring harness are on at all times. I had it looked at last week and I had to pay $400.00 but they never drove it and said the wiring harness is no longer their responsibility.”

“While driving my vehicle on a two-lane highway, I experienced multiple sequential electronic system failures (including the vehicle no longer detecting the smart key), and all electronic systems on the car became inoperative. I lost all instrumentation, including my speedometer and tachometer. At the same time, I also experienced a loss of motive power, and the engine of the vehicle began running extremely erratically before completely cutting off. I attempted to make a safe stop on the side of the road, but after doing so, could not restart the vehicle. The electrical systems of the vehicle continued to behave erratically, and the engine would not restart. I contacted roadside assistance, but they were unable to start the vehicle as well. It was towed to my local Hyundai dealership, but instead of expressing any genuine concern for the significant risk I endured while being placed In harm's way, they refused to fully diagnose the vehicle, and instead accused me of "jumping in reverse," even though I did no such thing (and don't even know what that means). The dealership has no evidence to suggest any such event took place, and simply wants me to pay over…”

“Vehicle in the middle of turning in to a hazardous highway lost power and then began to drive sluggish at 20 miles per hour skipping. It acted like the fuel injectors were not allowing it to get fuel. After having some one check it is exactly what was wrong.. It he vehicle had not caught up I would be dead as an oncoming vehicle did not realize the care was not moving.”

“ALL SAFETY FEATURE WARNING ALERTS (3) OF THEM, SINCE IT WILL NOT ALLOW ME TO CHECK ALL THAT APPLY THEY ARE THE FOLLOWING ADAPTIVE CRUISE CONTROL NOT WORKING, BLIND SPOT WARNING NOT WORKING, FORWARD COLLISON DETECTION NOT WORKING, LANE DEPARTURE WARNING NOT WORKING, LANE KEEPING ASSISTANCE NOT WORKING, PARKING COLLISION WARNING NOT WORKING REAR CROSS TRAFFIC WARNING NOT WORKING.”

“Vehicle is equipped with automatic headlights. They constantly turn on and off during the day as soon as you enter any type of shadow. This causes the headlights to “flash” the driver in front of you. While traveling on the interstate at 75 mph if you go under an overpass they turn on, less than 1 second but take 30-60 seconds to turn off! During that time the dash darkens and you cannot see the speedometer,HVAC controls, etc. Even with the headlight switch turned to OFF the dash continues to dim as if the headlights were on! I have had the dealer (San Tan Hyundai in Gilbert AZ) check them twice. Each time I am told operating as designed. This needs a software update to make the automatic headlight system less sensitive. There is no reason why my dash is dimming while the system is off or why the headlights are coming on during a bright sunny day because I drove through a shadow.”
