2023 HYUNDAI SANTA FE Complaints

The car loses power. The battery and key ignition light keep coming on. A message displays auto engine off. Please shift to n or p and start engine manually. After communicating and showing video proof of the incident, the dealership replaced the alternator and battery. The issues started around 5000 miles. The infotainment system lags and the car lags. Sometimes I am left on the road because the case refuses to cut on or off.

When accelerating from a stop, my car will not go over 20 mph. It just revs up like it’s not changing gears . I have to pull over and park it. It runs fine afterwards. This does not happen all the time. Usually it happens once a month. It’s been to the dealership 3 times. They drive it around the block and tell us that they can’t replicate the problem. Therefore, they don’t troubleshoot anything and return the car to me. I’m truly scared to drive it. I wrecked twice at a red light intersection.

My car won’t shift on the highway and all of a sudden I can’t drive more than 40mph. It also has not wanted to let me press on the gas and make it go as I’m driving bc Its jerking 4 or 5 times before it’ll register and go. Also, not too long ago, I was in a parking lot and went to leave and my car never notified me that there was a huge pillar next to me and I crashed into it, it was in my blind spot and couldn’t see it. My car has had many many other issues in which I can’t list, but I truly bought a lemon.

Driving on [XXX] in Victorville; sunroof shattered. Originally thought it was a tire blowout but there were no indications on the dash, no alerts, etc. Pulled over when safe to inspect vehicle and to make sure my kids were safe. Upon pulling over and exiting the vehicle, I started to make my way around the car to check the tires. All 4 tires were completely fine. Made a second round to double check everything, see if something went under the car, there was no sign of any damage. As I was getting into the car I noticed a huge hole in the sunroof, it was completely shattered. Safety of my family was at risk but fortunately it was a chilly morning and the sunroof was closed. Vehicle is available for request if needed but it currently located at the local Hyundai dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The purchase price was $35,800. As of today, I have paid a total of $24,590. The vehicle has a manufacturing defect that has significantly impacted its performance. The engine has been problematic, as it appears to be consuming oil, and it often fails to start on the first attempt, requiring me to press the button multiple times. The most concerning issue is that the car can unexpectedly shut off while I am driving. Additionally, there is an abnormal noise coming from the engine. I consider this situation serious, as it poses a significant risk to my safety. These symptoms appear on January 13/2025. I want to emphasize that I have completed all scheduled maintenance on time. I filled out reports regarding this issue, and I have attached two reports that confirm the vehicle is consuming 2 quarts of oil per 1,000 miles, vehicle is consuming oil due manufacturing defect. These reports were given to me by Safford Hyundai.

I had adaptive cruise control on and debris hit my windshield and I went into the rumble strip and eventually into the guard rail where the car essentially pingponged from there until it eventually stopped when the metal hit the front. It appears the emergency brake did not activate and the lane keep did not activate. My air bags did not deploy.

The car has shut down unexpectedly for at least six times while driving at roads and highways. When this happens, engine stalls and nothing works and all alarms and check lights turn on and activated. Driver has to pull the car to the roadside which cannot be imagined when in a highway with all cars driving at 65-70mpH and the car suddenly slows down to stop. The other problem is that when the car is turned off and on again, all alarm and faults go away, and it can be driven again! It clears all safety and alarm checks and lights and behaves like nothing has happened. Car was bought on June2023. The first incident happened on Aug2023 and the next one on Sep2023. The next incidents on Feb2024, Sep2024, Nov2024 and the most recent on March 2025. The car has taken to the Sport Durst Hyundai dealership (Durham, NC) after incidents, however dealership did not perform any repairs in first four times claiming they could not duplicate the incident! (service reports attached for 3) After the third incident, we opened a case with Hyundai company trying to invoke the Lemon law, but our request did not go through despite all evidence we provided. Shamefully, their final suggestion to us was to sell the car! This was around March/Apr 2024. (Final decision letter attached) On fifth time, the driver did not shut down the car and towed it to the dealership while leaving electrical system on. They checked the car and claimed they found the cause and changed a part from car claiming it has been fixed. This was on Nov.2024. At the time we did not notice but, apparently that was a lie to make us quiet. The last time (sixth time) the same incident happened on [XXX]. The car was towed to dealership and is left there. We do have all screenshots from engine failures, although the dealership tried to wipe the history at some point.

Two issues with powertrain/transmission: 1- The powertrain/transmission fails intermittently- vehicle RPM goes sky high but vehicle receives no power, seems to fail/lose power. Has happened in very dangerous road conditions where unexpectedly was struggling to get the motor to engage/get power to the vehicle. Check engine and check hybrid system lights accompanies the problem. 2- The car should be driveable in electric only mode without use of gasoline. The powertrain/transmission seems to struggle to shift between electric and gas motors. HYUNDAI cannot seem to correctly diagnose or fix the issue. Does not seem they have proper diagnostic process included on the car- despite finding error messages stored in computer, they initially said they could not recreate the problem and therefore could not fix. 3 different trips to Hyundai dealership repair center, in total they have had my car for 10 weeks. They have replaced the transaxle and sent the car home, but that did not cure the issue. They now have my car again. It just does not seem they know how to identify or fix the issue. From online forums, I have learned MANY owners are experiencing the same problem and the same challenge to diagnose.
