2020 Hyundai IONIQ PLUG-IN HYBRID: complaints, problems and recalls

In the middle lane of a multiple lane highway, it suddenly gave a very confusing warning on the dashboard. It lost power and slowed down quickly to below 40 mph. It didn't help to press down the gas pedal. I was forced to switch from the middle lane to the passing lane in order to reach the shoulder. The car was side swept by another car in the passing lane because it was at low speed. Once it reached on the shoulder it stopped completely. If it gave a clear warning, for example, "pull out immediately!", and flashed the emergency light automati…

While my wife and I were driving on the interstate, all dashboard warning lights came on at once, and the car began rumbling at regular intervals as it tried and failed to switch from electric vehicle (EV) mode to hybrid EV (HEV) mode, and the engine wouldn't start. At the same time, the power steering stopped working, the car struggled to go more than 40 MPH, and it started accelerating on its own and would not stop until I hit the brake. Each time the engine tried and failed to start, the car started accelerating again. I pulled off at a gas …

When the engine is turned off, and the car is not in park, it rolls. When the engine is turned off the car should automatically switch to P to prevent it from rolling. Our car was left in R with the engine off. And instead of switching to P automatically, it just rolled away and hit the neighbors garage.

The "Auto Hold" feature on my Hyundai Ioniq malfunctioned, displaying a dashboard warning: "AUTO HOLD conditions not met. Press brake pedal." This message randomly appears while driving or stopping, and it deactivates the Auto Hold and Electronic Parking Brake (EPB) functions. In some cases, the car rolls after stopping because the system fails to hold the vehicle. This issue compromises vehicle safety, especially on inclines or during stop-and-go traffic. It puts me, passengers, and other drivers at risk. The problem has occurred multiple tim…

I am writing to dispute the denial of my paint defect warranty claim formally and to demand that Hyundai Motor America reconsider its decision.

Timeline of Events • I first contacted Hyundai Customer Care by phone, and was directed to visit an authorized dealership. • On May 8, 2025, I visited Tustin Hyundai, wh…

APPARENTLY, A FRONT-END COLLISION OCCURRED WHILE THE VEHICLE WAS PARKED AND UNOCCUPIED IN A PARKING LOT RESULTING IN $1232 IN DAMAGE TO BODY PARTS, ANTI-COLLISION RADAR, AND ELECTRONIC CRUISE CONTROL. ASTONISHINGLY, THE BUMPER AND EVEN THE FRONT LICENSE PLATE SUSTAINED ALMOST NO VISIBLE DAMAGE WHATSOEVER. SEE PHOTOS ATTACHED. THE COLLISION MUST HAVE HAPPENED AT EXTREMELY LOW SPEED AND IT IS OBVIOUS THE FRONT BUMPER DID NOTHING TO PROTECT THE REST OF THE CAR--ITS PRIMARY INTENDED FUNCTION. THIS WOULD BE THE EQUIVALENT OF A HOUSE BURNING DOWN…

I leased the vehicle in 03-2021 and within the first year took the car back to the dealer 3 times for complaint on braking system. The brake pedal would loose pressure and stopping distance would extend further than anticipated. the dealer consistently told me that they could not duplicate the problem. now has gotten to the point that EBP light and HOLD light stay on steady and red Brake light flashes, due to this the smart cruise control and crash avoidance system become inoperable. Recently became aware that this issue is known to Hyundai an…

During a highway trip that was bumper to bumper traffic at approximately 15mph, the car suddenly would not accelerate while operating on gasoline (not electric). The engine revs would increase to maximum without movement from the car (as if the car was in neutral). After checking the gear lever to make sure it was still in D, tried to accelerate again and engine rev high without movement. Eventually car came to stop with brakes, and the car could move on electric power (in hybrid mode), pulled over and turned off the car to visually inspect. Af…

Installing a car seat and the belt buckle failed. The plastic part split and no longer holds the belt together. This was under regular pressure with standard leverage that the car seat design calls for. Nothing was ever on top of the buckle and it is not damaged in any other way at all other than the failure. They refused to replace it via warranty.

The engine coolant can leak into the exhaust because air a known design flaw. When the the engine turns on after being in electric mode the coolant pump starts and pushes it out the exhaust causing a sudden over heating of the engine. This causes the car to stall and can be very dangerous at freeway speeds.
