2021 Hyundai Ioniq hybrid problems
The Hyundai Ioniq is a compact five-door liftback manufactured and marketed by Hyundai. The nameplate Ioniq is a portmanteau of ion and unique. It is marketed as the first Hyundai automobile to be offered without a standard internal combustion engine, but rather sold in hybrid, plug-in hybrid, and all-electric variants.
The Ioniq Hybrid debuted in South Korea in January 2016, with all three variants debuting at 2016 Geneva and New York auto shows. The hybrid variant launched in its home market in February 2016, followed by the electric model in July 2016. The plug-in hybrid version followed in February 2017.
From its first model year (2017) through the 2019 model year, the Ioniq Electric had been the EPA's most efficient vehicle with a rated fuel economy of 136 miles per gallon gasoline equivalent (24.8 kWh/100 mi; 15.4 kWh/100 km). The Ioniq Blue Hybrid version has been rated at 4.1 L/100 km (58 mpg‑US), making it the most fuel-efficient hybrid vehicle to be mass-produced.
Following its discontinuation in South Korea in 2021, production of the Ioniq ended in July 2022 in favour of battery electric lineup of Ioniq-badged models starting from the Ioniq 5 hatchback and Ioniq 6 sedan with Ioniq 7 to follow.

Common 2021 Hyundai Ioniq hybrid problems
The Hyundai Ioniq Hybrid 2021 is a popular choice among car buyers due to its eco-friendly nature and fuel efficiency. However, like any vehicle, it has its fair share of issues reported by owners. Here are some of the most common problems with the Hyundai Ioniq Hybrid 2021 based on complaints from owners:
- Coolant leak: There has been a recall for early Ioniqs built between 4 October 2016 and 31 March 2017 related to coolant that might leak into the electric power control unit. This can result in engine overheating and potential damage to the electrical system. If you suspect your car might be affected by this recall, contact your local Hyundai dealer for further assistance.
- Risk of power relay fire: Some examples of the Hyundai Ioniq Hybrid 2021 may suffer from a faulty power relay that could, in extreme circumstances, catch fire. Hyundai dealers are to replace the power relay and inspect the power cable and relay assembly for any damage and replace if necessary.
- Intermittent engine problems: Some owners of the Hyundai Ioniq Hybrid 2021 have reported intermittent engine problems, such as the engine orange light coming on without warning and the car lurching as if an invisible force is putting on the brakes gently. These problems can be caused by issues with the hybrid engines not communicating properly with each other, as well as unknown faults (codes 047200 and 047100).
- Speaker problems: On rare occasions, some owners have reported that the speakers in their Hyundai Ioniq Hybrid 2021 will suddenly stop working, with sound from media, radio, and car SatNav not working, although the onscreen system seems fine. This issue can be resolved by leaving the car for a couple of hours and starting it up again.
While these issues can be concerning, it's important to note that the Hyundai Ioniq Hybrid 2021 has a splendid reliability record and finished seventh out of 32 manufacturers in the most recent What Car? Reliability Survey. Additionally, all issues should be covered by the five-year manufacturer's warranty, so defects shouldn't be a major issue for owners.
Is Hyundai Ioniq hybrid a good car?

Basically, unauthorized third-party Bluelink apps are requesting information too frequently from the Ioniq 5.

If you have the opportunity, I highly recommend finding an Ioniq with the Ultimate package. The benefits of this package, which costs $2000, are definitely worth it. While it's important to note that the 55+ mpg advertised may not be entirely realistic, I have found that I average around 48-52 mpg. The Prius may be a more accurate representation of mpg. Overall, the Ioniq is an excellent vehicle that offers a better ride and feel than the Elantra and even the Sonata. Lastly, I wanted to express my gratitude for the research and assistance provided by edmunds.com in helping me find the best price for my car. Thanks to their help, I was able to negotiate the price down below the suggested retail price and even purchase an extended warranty. Thank you again for your assistance!

The car is good, but there are some things about the drive that you have to get used to when switching from a regular car to this hybrid. I have never driven another hybrid car, so I cannot compare it to another hybrid, but there were things that I had to get used to. Other than that, the car is great with great gas mileage. I went on a road trip and was averaging 54 mpg, even on a slight incline with off and on traffic. I was still impressed.

I'm trying my car but so far I'm having lots of fun. I leased because of the warranty, price and the possibility to change to a hybrid, and I'm in love with it. I'm having fun. Super safe car!

I'm so glad to hear that you're enjoying your Ioniq! It sounds like you've had a great experience with both your 2017 SEL and your new 2020 Limited. The upgrades in the 2020 model sound fantastic, and it's great to hear that you're still getting such impressive gas mileage. While it may not be as luxurious as your previous Volvo S60, it sounds like the Ioniq is still a comfortable and reliable option for long road trips. Thanks for sharing your positive experience with us!

Are you having problems with your 2021 Hyundai Ioniq hybrid?

I've been driving my 2020 Ioniq for a year and a half now, and while I've had some issues with the electronics, I still have a soft spot for this car. Unfortunately, my infotainment system and backup camera have each been replaced twice already, and the front proximity sensors also failed. It's been in the shop half a dozen times or so, and I'm currently waiting to hear back from Hyundai about potentially buying it back. Despite these issues, I still think it's a beautiful car that drives well. However, I have noticed that it hasn't quite lived up to the EPA rated 55mpg, hovering around 42mpg instead. This is comparable to what my 2008 Prius was getting when it was 12 years old, which is a bit disappointing. I'm considering a hybrid SUV instead, but I'm hesitant to go with another Hyundai. I've even had trouble finding a dealership willing to take my Ioniq in trade due to its issues. Hopefully, Hyundai will come through and buy it back.

I am 5'5 and unfortunately find the seats uncomfortable as they do not provide adequate support for my back, causing me neck and back pain. Additionally, the back windshield is too small and rounded, creating corner blind spots. When I first got the car, I almost reversed into another car due to these blind spots. It's ironic that my husband initially dismissed my concerns and told me I just needed to get used to the car, but months later he was involved in a collision while reversing due to the same blind spots. I emphasized to him that cameras alone cannot be relied upon and he now agrees with me.

The fuel economy of this car is impressive due to its lightweight construction. However, some of the parts, such as the splash guard, are made of fragile materials and can be expensive to replace. The SEL trim comes with great features like Lane Change Assist, Lane Assist, and a sunroof, which are definitely worth the extra cost. Although the car can be a bit uncomfortable and noisy, there are other options available in the market that are more affordable and still fuel-efficient, such as the Elantra, Toyota Corolla, or Honda Civic. If you're looking for a hybrid, the Ioniq is a good option as long as it's priced at CAD$20K or less.
