Both have serious safety issues, but the Ioniq's lower complaint rate may indicate fewer problems. Source: NHTSA owner complaints.
The picture
Is the Tesla Model 3 or Hyundai Ioniq more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Tesla Model 3
The Tesla Model 3, in ownership terms, is a high-tech electric vehicle that relies heavily on software for its advanced driver assistance features. The complaint pattern reveals a car where software updates and autonomous driving systems frequently malfunction, causing unpredictable braking, loss of speed control, and safety system failures. Owners report repeated service visits and a sense of the car acting on its own, which can be alarming and potentially hazardous.
Hyundai Ioniq
The Hyundai Ioniq, available as hybrid, plug-in hybrid, or EV, is a more conventional electrified vehicle, but its complaints center on electrical gremlins and powertrain issues. Owners report sudden power loss, hesitation when accelerating, and problems with the dual-clutch transmission, which can be dangerous in traffic. While fewer complaints overall, the nature of these issues suggests a car that may unexpectedly lose power or fail to respond, impacting drivability and safety.

The problems owners report
The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

- 01FORWARD COLLISION AVOIDANCE1,728
- 02UNKNOWN OR OTHER687
- 03VEHICLE SPEED CONTROL630
- 04SERVICE BRAKES563
- 05ELECTRICAL SYSTEM553
Owners report the system causing unexpected braking or failing to work correctly, often after software updates. Some describe the car braking for no reason on clear roads, increasing the risk of rear-end collisions.
Complaints include the main control unit going blank, disabling cruise control and speedometer, and software updates that disable legally required functions. This can lead to loss of speed control and driver confusion.
Unexpected braking events on the freeway are reported, with the car applying brakes without warning. Owners also mention regenerative braking and other safety features shutting off, compromising braking performance.
Software updates have caused multiple safety and convenience features to fail simultaneously, including lane departure, autopilot, and stability control. This systemic failure can leave the driver without critical assistance systems.
“SHORTLY AFTER PURCHASING THE CAR IT RECEIVED A SOFTWARE DOWNLOAD CALLED EMERGENCY LANE DEPARTURE AVOIDANCE WHICH IS TESLA'S FANCY NAME FOR A LANE DEPARTURE WARNING SYSTEM. I HAVE TAKEN THE CAR INTO THEIR SERVICE CENTERS 3 TIMES TO HAVE IT REPAIRED BECAUSE IT…”

- 03FUEL/PROPULSION SYSTEM100
- 04ENGINE57
- 05SERVICE BRAKES56
Owners report issues with the 12V auxiliary battery, including unsecured brackets and terminals, leading to potential electrical failures. Also, the regenerative braking system can change levels without input, causing unexpected strong braking.
The car may fail to switch between EV and hybrid modes, causing rumbling and loss of power. The dual-clutch transmission can be unresponsive or sluggish when accelerating from a stop, creating a hazard in traffic.
Sudden deceleration and hesitation when shifting from reverse to drive are reported, which can leave the driver unable to accelerate when needed, such as when pulling out of a driveway.
In hybrid models, the engine can stall or lose power on the highway, with dashboard warnings and smoke in the cabin, indicating a potential fire risk. This is a serious safety concern.
“Following a 12V auxiliary battery replacement at Dick's Hillsboro Hyundai [XXX] , April 3, 2026), the battery hold-down bracket was left completely unsecured. The retaining bolts were absent, (later found loose in the cargo tray area). The battery terminal co…”
