The picture
Is the Hyundai Tucson or Hyundai Ioniq more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Hyundai Tucson
The Hyundai Tucson is a compact SUV with a mixed reliability record. Over 10 years, it has averaged 311 complaints per year, with engine problems dominating.

Owners report stalling while driving, often with a flashing check engine light, and engine knocking that can lead to towed vehicles. This is the most complained-about system, with 1,315 complaints, indicating a pattern of serious engine failures that could strand a buyer.
Complaints include steering column lockup and catalytic converter efficiency failures. These issues can affect control and emissions, and may require expensive repairs.
Owners describe a hissing/buzzing noise and a soft brake pedal at low speeds, which can reduce braking confidence. With 387 complaints, this is a notable safety concern.
AC system failures are reported, with compressors and condensers needing replacement, and sometimes the entire system. Electrical issues can be costly and uncomfortable.

- 04SERVICE BRAKES58
- 05ENGINE57
The most common issue is the auto hold and EPB malfunction, triggering warning lights and deactivating the system. This can lead to confusion and potential rollaway if not addressed.
Reports include unintended acceleration in reverse and loss of power with bucking. These are serious drivability and safety concerns that could lead to crashes.
High-voltage isolation faults (DTC P0AA6) and sudden deceleration are reported. These can indicate battery or hybrid system problems that are expensive to diagnose and repair.
Auto Hold malfunction and continued movement after braking are noted. This suggests brake control issues that could compromise stopping ability.

Buyer analysis
Hyundai Tucson or Hyundai Ioniq: which should you buy?
The Hyundai Ioniq has far fewer complaints per year (94.3 vs. 311.2) and no reported deaths, while the Tucson has 1 death and more crash-related complaints. In practice, the Ioniq may be less likely to leave you stranded, but it has its own electrical quirks. The Tucson's higher complaint rate, especially for engines, suggests higher ownership risk.
Key differences
- The Tucson has 3,112 complaints over 10 years, while the Ioniq has 566 over 6 years—the Tucson averages over three times as many complaints per year.
- Engine problems dominate Tucson complaints (1,315), with reports of stalling and knocking; the Ioniq's top issue is electrical (369), mainly auto hold/EPB malfunctions.
- The Tucson has 147 crash-related complaints and 1 death; the Ioniq has 25 crash-related and 0 deaths.
- The Ioniq has 13 recalls, including for high-voltage battery and inverter issues; the Tucson has 27 recalls, covering steering, brakes, and transmission.
- Check for any signs of engine stalling or knocking, and ask for maintenance records; a flashing check engine light is a red flag.
- Test the brakes for soft pedal or unusual noises at low speeds, as owners report hissing and buzzing.
- Test the auto hold and electronic parking brake functions; warning messages like 'AUTO HOLD conditions not met' indicate a known issue.
- Listen for any unusual noises or warnings related to the high-voltage system, and check for recall completion on the battery and inverter.
Before you buy
- Obtain a full vehicle history report and confirm all recalls have been performed.
- Have a trusted mechanic inspect the engine and transmission for the Tucson, and the electrical and hybrid systems for the Ioniq.
- Test drive both vehicles extensively, including braking, accelerating, and using all electronic features.
- Ask the seller for maintenance records, especially for oil changes and any engine or electrical repairs.
- Check for outstanding recalls by VIN with a Hyundai dealer before purchase.
