Problem overview

Some Hyundai Elantra owners report experiencing issues with power steering, power windows, and airbags after replacing the alternator. These problems may arise if the power steering pump is stressed, causing the belt to slip and resulting in dimming lights. Additionally, owners have noted that power windows may stop functioning due to faulty electrical systems, making it essential to check the fuses. Moreover, some drivers have reported airbag warning lights appearing on the dashboard, potentially linked to electrical issues or wiring connections. It is recommended that affected owners check the power steering fluid, inspect the belt, ensure fuses are intact, and examine the wiring connections. If these issues persist, consulting a professional mechanic for further diagnosis and repair is advisable.
