Hyundai Sonata

Issue: 
On certain vehicles, the check valve for the purge control system could wear and cause the fuel tank to expand. As a result, the fuel tank could contact hot components and fuel could leak.  
Note: This recall only affects certain vehicles equipped with a 1.6 L turbocharged engine. This safety recall replaces emissions recall no. ECR-H0003-24-005 (Hyundai recall no. C0566). Vehicles that were repaired under that recall also require this repair. 

Safety Risk: 
A fuel leak can create the risk of a fire. 

Corrective Actions: 
Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the check valve and update the electronic control unit (ECU) software. The dealer will also inspect the fuel tank and surrounding components and repair them, as necessary.

Issue: 
On certain vehicles, brake fluid could leak into the control module for the antilock brake system (ABS) and cause it to short circuit. 
Note: This recall replaces recall R0246 (Transport Canada recall number 2023-527). For the Sonata model, only the Sonata Hybrid model is affected by this recall. 

Safety Risk: 
A short circuit could create a fire risk, even while the vehicle is parked and turned off. 

Corrective Actions: 
Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to replace the fuse for the ABS module. Hyundai recommends that you should park your vehicle outdoors and away from other vehicles or structures until the recall repairs have been completed.

Issue: 
Hyundai is conducting a special service campaign to upgrade the safety plug fuse. On certain Sonata Hybrid (HEV) models, the safety plug fuse in the power relay assembly could blow and cause a sudden loss of hybrid system power. 

Safety Risk: 
A loss of hybrid system power may increase the risk of a crash. 
 
Corrective Actions:  
Hyundai will notify owners by mail and instruct you to take your vehicle to a dealership to replace the 125-A safety plug with one that has a 150-A rating.

Issue: 
On certain vehicles, a fault in the transmission oil pump can cause the vehicle to enter "fail-safe mode". When this happens, a programming error can cause a sudden loss of power to the wheels after 20-30 seconds. 
Note: This recall only affects certain vehicles equipped with an 8-speed dual-clutch transmission (DCT).  

Safety Risk: 
A sudden loss of power to the wheels could increase the risk of a crash.  
 
Corrective Actions: 
Hyundai will notify owners by mail and instruct you to take your vehicle to a dealership to inspect and, if necessary, replace the transmission. The dealer will also update the transmission control unit software.

Issue: 
Hyundai Auto Canada is conducting a Product Improvement Campaign that provides an update to the engine control module to detect potential problems before an engine fails. An engine failure would cause a sudden loss of power with an inability to restart. 
Note: This only affects certain vehicles equipped with a 2.0 L Nu GDI engine. For the Sonata model, only the Sonata Hybrid and Plug-In Hybrid (PHEV) models are affected by this campaign. This is an expansion of R0180 (Transport Canada #2021-575). Any vehicle that received a software update under campaign R0180 does not require this update. 

Safety Risk: 
A sudden loss of engine power could increase the risk of an accident. An engine failure could also create the risk of a fire. 

Corrective Actions: 
Hyundai will notify owners by mail and advise you to take your vehicle to a dealer to update the software for the engine control module. 
Note: Hyundai recommends that you should always follow the correct vehicle maintenance schedule, which is printed in the Owner's Manual. If you experience unusual engine noise, reduced power, or a check engine/oil warning light, Hyundai advises you to immediately visit a Hyundai dealership to have your vehicle diagnosed.
