Hyundai Repair

Hyundai has built a reputation for fuel efficiency, smart technology, and reliability. Models like the Elantra, Sonata, Tucson, and Santa Fe are everywhere in San Francisco, Daly City, and South San Francisco, proving their popularity. But even the best vehicles develop problems.

Hyundai models from 2012 to 2024 share common mechanical and electrical failures that can go from minor annoyance to full-blown breakdown if ignored. At Cowden Automotive in San Francisco, we see these issues every day. Here are seven Hyundai problems that can leave you stranded—and how to avoid them.

Catastrophic Engine Failure
If your Sonata, Santa Fe, or Elantra (2011-2023) is making knocking noises, consuming oil at an alarming rate, or stalling, you’re looking at a known engine defect. The Theta II GDI and MPI engines have had issues with premature wear on rod bearings and piston rings, leading to complete failure. Some drivers experience sudden power loss at highway speeds—a dangerous situation. If your oil levels drop between changes or your engine feels rough, don’t wait. A failing engine doesn’t fix itself.

CVT Transmission Hesitation
A reliable transmission should shift smoothly, but Hyundai’s 2015-2024 Tucson, Kona, and Veloster models equipped with Continuously Variable Transmissions (CVTs) have been known to hesitate, jerk violently when shifting, or fail to accelerate after stopping. Some drivers report sudden transmission failure with little warning. What’s the cause? Overheating CVT fluid, failing solenoids, and worn drive belts. If your Hyundai hesitates or shifts erratically, don’t ignore it—CVT failures are expensive.

Power Steering Issues
If you drive a 2011-2018 Hyundai Elantra or Sonata, you may have noticed a clicking noise when turning the wheel. What is the culprit? A failing steering coupler inside the electric power steering system. While it starts as a noise, it leads to loose, unresponsive steering that can make highway driving dangerous. If your steering feels unpredictable, it’s time for an inspection before it compromises your safety.

Weak Alternators
A car that randomly won’t start, struggles with dimming lights, or constantly drains the battery might have more than just a weak battery—it could be an alternator problem. Many 2013-2023 Hyundai Santa Fe, Tucson, and Sonata owners report alternators that fail prematurely, leading to inconsistent voltage output. If your Hyundai’s electronics flicker or your car struggles to start after sitting for a short time, don’t just replace the battery. A failing alternator can leave you stranded without warning.

AC Compressor Failures
San Francisco’s weather can be unpredictable, and when the heat hits, you need a functioning AC. But many 2014-2022 Hyundai Elantra, Sonata, and Santa Fe models have AC compressors that fail unexpectedly. The problem? Internal compressor failure, refrigerant leaks, and failing relays. One day your AC works fine; the next, you’re stuck in traffic with warm air blowing in your face. If your AC isn’t as cold as it used to be or makes loud noises when engaged, the compressor is on its way out.

ABS and Traction Control Malfunctions
A flashing ABS, traction control, or parking brake warning light might not seem urgent—until your braking system doesn’t respond when you need it. Many 2015-2024 Hyundai Tucson, Palisade, and Santa Fe models have reported faulty ABS wheel speed sensors that trigger false warnings, limit traction control, or even reduce braking performance in slippery conditions. If your dashboard is lit up with warnings, get your braking system checked before the problem becomes dangerous.

Sunroof Rattles and Leaks
Hyundai’s panoramic sunroofs are a premium feature—until they start leaking, rattling, or even shattering unexpectedly. Many 2013-2023 Santa Fe, Tucson, and Sonata owners report sunroofs that won’t fully close, produce wind noise, or allow water to seep into the cabin. If you see water stains on your headliner or hear a rattling noise above your head, your sunroof may need realignment or a new seal before it turns into a bigger issue.

Fix Problems Early—Or Pay More Later
Hyundai makes solid vehicles, but every car has weaknesses. If your engine is knocking, your transmission is slipping, or your power steering feels loose, those aren’t quirks—they’re warnings. Ignoring them won’t make them go away. A rough shift today can turn into a blown transmission tomorrow. A weak alternator can drain your battery and leave you stranded. A clicking steering wheel can make high-speed turns unpredictable.
