2023 Hyundai Elantra Service and Repair Manual
Hyundai built the 2023 Elantra with three distinct powertrains spread across sixteen trims, which is exactly why fitment matters: this factory service and repair manual is keyed to this precise year, engine and trim, so the figures and sequences it gives are the ones Hyundai issued for your car rather than values carried over from another Elantra year.

Known issues on the 2023 Elantra. Two recalls are on federal record for this model year. The first concerns the automatic transmission's electric oil pump: the recall covers the electronic controller for the Idle Stop & Go oil pump assembly, and an electric oil pump assembly that overheats increases the risk of a vehicle fire. The second concerns the driver's front air bag, where the emblem on the air bag cover may not have been welded properly; a detached air bag cover emblem may strike a vehicle occupant, which can increase the risk of injury. Owners have filed 146 complaints for the year and Hyundai has issued 49 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.
From tracing an Idle Stop & Go fault to an air bag cover inspection, a turbocharged N Line service or a hybrid system check, it keeps you on the OEM procedure and the correct specification for your specific 2023 Elantra.
Hyundai Motor America (Hyundai) is recalling certain 2022 Elantra N and 2022-2023 Elantra vehicles. The emblem on the cover of the driver's front air bag may not have been welded properly, which can result in the emblem detaching upon deployment.
A detached air bag cover emblem may strike a vehicle occupant, which can increase the risk of injury.
Dealers will replace the air bag, free of charge. Owner notification letters were mailed October 14, 2022. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 234.

I have been encountering a series of troubling and erratic issues with my vehicle. These problems occur under various driving conditions, including acceleration, steady-state driving, and braking. However, the most prevalent and problematic occurrences seem to transpire during acceleration and braking. During acceleration, I've observed inconsistent behavior. Sometimes, the car shifts smoothly, with minimal torque drop between gears. On other occasions, the vehicle accelerates initially but then

On July 28th I had an accident and hurt myself because seatbelt did not work
The car was involved in an accident. It was going 5-10 mph and hit a light post. There was minor body damage and about 10-15 seconds after initial impact the airbags deployed and cracked my windshield. The car was considered a total loss.
The contact owned a 2023 Hyundai Elantra.

The contact owned a 2023 Hyundai Elantra. The contact stated that while driving at 35 MPH, another vehicle failed to stop at a stop sign; as a result, the contact's vehicle was struck by the driver's side door, sending the vehicle careening 50 feet before coming to a complete stop.

A police report was filed, with injuri
Horn has stopped working. A driver was about to change lanes into my vehicle on the highway, and I went to honk my horn to alert them, but it would not work. It is unclear if the issue is with the sensor in the steering wheel, or with the wiring or horn itself. I have continued to test the horn over the next few days and confirmed that the issue is persistent. The lack of a horn meant I was nearly able to avoid an accident by swerving away from the other vehicle. If there had not been a gap in t
While driving at highway speeds the vehicle will suddenly decelerate forcing vehicles behind said vehicle to make defensive maneuvers to avoid hitting our vehicle. We have taken the vehicle to the dealership twice for this condition. This time we were told it was the EGR valve, but it was on backorder. We are now forced to drive this vehicle until it is repaired.
On Saturday December 16th my vehicle was parked as I was shopping. When I returned to the vehicle and started it, lights began to light up on the dashboard. They included the rear collision, front collision, airbag, parking brake, battery, tires, blind spot, and others. I called Hyundai and they said that they did not receive any communication from the vehicle stating that there was a problem. The front and rear cameras stopped working and I could no longer tell if my turning signals were o
Horn is inoperable due to internal fault. Horn receives power when button is depressed, relay actuates, but horn does not sound. There is no warning system in place for this fault.
The horn constantly fails and needs to be replaced. This is not only an issue with the Elantra, as I've seen it as a common issue among a range of Hyundai vehicles. Even my local dealership has many horns on hand, as it is so common for them to be replaced, as they stated. I've gone through 2 horns in less than a year. This is complete negligence on Hyundai's part, as the horn is a critical safety feature of any highway vehicle. They replace it knowing it's going to fail, completely disregarding
