2019 Hyundai Santa Fe problems

Filed Nov 5, 2026 · Engine · WA

The Auto Stop feature will activate at a stop light and stop the engine. Occasionally it will not restart. I have to put the car in park, remove the key, wait a minute, reinsert the key and attempt a restart. It sometimes takes several tries before the engine will restart. I have nearly been hit by other cars multiple times. The dealer, Spokane Hyundai, has not been able to recreate the incident and has no clue as to why this happens. It is VERY dangerous.

While driving on the freeway at approximately 73 mph, I heard a very loud bang that sounded like something had struck my car. I initially thought a rock had hit my windshield, but I couldn't see any damage. Later, I remembered the incident and went to the garage to inspect my car. After checking the windshield and walking around the front and sides without finding any damage, I climbed up to inspect the roof. I noticed something unusual about the smaller fixed glass panel in front of the sunroof, directly behind the windshield. When I ran my finger across it, I heard a slight cracking sound and felt a rough texture. That's when I realized the entire panel had shattered. The shattered glass poses a potential safety risk due to the possibility of glass falling into the vehicle or further breaking while driving at highway speeds, going over bumps, closing the car doors etc. The panel is available for inspection. The vehicle has not yet been inspected by a dealership or manufacturer, and the cause of the failure has not been determined. There were no warning lights or messages before the incident. After researching the issue, I found multiple reports from Hyundai Santa Fe owners describing similar incidents. Relevant the federal safety agency complaints include: Complaint #11502029 (2020 Santa Fe): Front sunroof glass suddenly shattered with no apparent external impact. Complaint #11548273 (2020 Santa Fe): Stationary glass panel in front of the sunroof shattered while parked. Complaint #11253008 (2019 Santa Fe): Panoramic sunroof shattered while driving with no evidence of an external impact. Complaint #11480753 (2019 Santa Fe): Rear panoramic sunroof panel reportedly exploded while driving approximately 70 mph. I believe these reports warrant further investigation into a possible recurring issue with Hyundai Santa Fe sunroof glass or its assembly, particularly given the potential safety risks of unexpected glass failure while driving.

2019 Hyundai Santa Fe, XXX oil light came on but it wasn't time for my next oil change. I stopped by Advanced Auto to get code read, was told Camshaft sensor error. A week later, had my mechanic check code before doing oil change. He got the same code and ordered and replaced camshaft along with doing oil change. Drove two miles away from mechanic, oil and engine light came on. A week later I left my car with mechanic to check and replace oil sensor. The oil light was still on and he told me to take the car to the dealer because the engine is probably bad. Took car to the dealer, told them of all the previous work I just had done and asked them to check for any recalls or campaigns. Two recall/campaigns were updates, 9C2 and P33. Was told I needed Oil Flow Control valve Exh, got that replaced but lights were still on. Next, I was told I needed an Oil Pressure Switch, got that replaced, lights were still on. Dealer wants to do exploratory search to see if they can find out why lights are on but tell me I will have to pay for everything as they replace parts. What? I just paid them $1224.67 and nothing's fixed, lights are still on. Spoke with svc rep, [XXX] over the phone, she told me the engine light is still on and the oil light goes off during acceleration, I picked up my car as I can't keep getting nickeled and dimed after every part is replaced with no correction to the issue I came in for. Now the car runs like shit and burning gas like crazy. Engine is making sounds and acceleration is loud and slow. I believe this engine is going out and needs to be recalled as well. So many Santa Fe's are having this same issue and at 44,000 miles, I shouldn't be having any problems with this car. How is this allowed from the manufacturer? These engines are going to stop working, hopefully not while anyone is driving. Hyundai should be made to fix this asap.

On August 14 2026, I drove my 2019 Hyundai Santa Fe approximately one mile from my residence to work at approximately 5:00 AM. The vehicle was operating normally and I experienced no warning lights, unusual noises, odors, smoke, or other indications of a problem. I parked the vehicle in an outdoor parking lot and the vehicle remained parked and turned off for approximately four hours. At approximately 9am, I was notified that my vehicle was smoking. A person who was walking past the vehicle observed the smoke, obtained a fire extinguisher, and extinguished the fire. The fire department subsequently responded, disconnected the vehicle battery, and opened the rear of the vehicle to ventilate it. The fire and resulting heat damage were concentrated on the driver's side rear of the vehicle, directly behind the driver's-side rear tire and in the area of the rear bumper. The plastic at the base of the bumper melted, and melted bumper material was observed dripping onto the ground. The responding fire marshal inspected the vehicle and indicated that the electrical box located in this area may be associated with the origin of the fire. Wiring from this area runs to a non-original/non-Hyundai-installed trailer/tow attachment. The exact cause and origin of the fire have not yet been conclusively determined. The vehicle had otherwise operated normally during my ownership, with little to no significant problems prior to this incident. The vehicle is currently being preserved for inspection by my insurance company and mechanic. I am reporting this incident to the federal safety agency because the vehicle caught fire while parked and unattended after having been driven only approximately one mile, and because the suspected area of origin includes electrical components and wiring associated with the rear of the vehicle. No collision preceded the fire. There were no injuries. I am requesting that the federal safety agency consider this incident as a potential vehicle/electrical safety issue and investig

On 03/26/2026, my 2019 Hyundai Santa Fe received Hyundai Service Campaign 9C2 (TSB 26-01-013H-1), which included an Engine Control Module (ECM) software update for Theta II emissions improvement. The vehicle did not have the following drivability problem before this software update. Immediately after the 9C2 update, the vehicle began jerking/bucking slightly at low speeds, most noticeably around 10-20 mph when coasting with no accelerator input or when applying very light throttle. Acceleration response also feels slower than before the update, with noticeable hesitation when the accelerator is pressed. The problem is most noticeable during the beginning of a drive when the vehicle is cold. After driving for some time and the vehicle warms up, the symptoms improve, although the change in drivability remains noticeable compared with operation before the update. There have been no warning lights or warning messages associated with the problem. The issue began immediately following the ECM software update. The vehicle has not yet been returned to the dealer for diagnosis or confirmation and is available for inspection. I am concerned about the safety implications of delayed or unpredictable acceleration response, particularly when entering traffic, crossing an intersection, or merging when timely acceleration may be necessary. I am reporting this because the condition began only after Hyundai Service Campaign 9C2 was performed and I believe the federal safety agency should evaluate whether this ECM software update is causing similar drivability and acceleration problems in affected vehicles.

The vehicle experienced a sudden, intermittent engine stall while driving, specifically when slowing down or coasting to a stop in live traffic. When the engine dies, the vehicle immediately loses engine power, power steering, and power braking assist, creating an extreme safety hazard. After stalling, the vehicle refuses to restart for several minutes. An authorized Hyundai dealership previously replaced the high-pressure fuel pump under warranty to address this issue, but the dangerous stalling has persisted over the last 2,000 miles. The vehicle continues to randomly shut off without throwing a permanent check engine light or diagnostic trouble code, and the manufacturer has failed to correct this critical safety defect.

The car started having problems immediately after replacement with a new battery. The issue with the ISG (Idle Stop and GO System) started appearing. When the Auto Stop Indicator turns green, the car stalls which puts my life at risk. I have spoken to a number of mechanics and I am not getting a satisfactory answer on how to fix this problem.. One mechanic told me it was the starter which turned out not to be true. I have also spoken with a number of other mechanics and they are clueless on how this problem can be remedied. And the Hyundai dealter wanted $275 just to look at it but with no guarentee. The whole issue is putting my life and other motorists at risk.

2019 Santa Fe with 80,000 miles showed signs of excessive oil consumption. Service was scheduled with licensed Hyundai franchise service center. Known oil consumption issues on Theta II engines for that year. Testing requires 3 steps. First step is to change the oil and document levels. Engine is tested for 1000 miles then returned to service center. After 1000 miles, service center reports 2.5 qts of oil per 1000 miles. Hyundai corporate was contacted where they approved warranty work for the vehicle. Step two requires Combustion Chamber Cleaning. During this portion of the work, service center calls about fire that took place immediately after a test drive. Dealership states engine and components destroyed.
