2020 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 2020 Hyundai Ioniq hybrid problems
The Hyundai Ioniq Hybrid 2020 has been praised for its fuel efficiency, low emissions, and smooth ride. However, there have been some reported issues by owners that are worth noting.
- Soy-based wires chewed by rodents: This is a common problem with the 2017 Hyundai Ioniq Hybrid, which also affects the 2020 model. The soy-based wires in the engine bay are particularly attractive to rodents, who can cause extensive damage to the car's electrical system by gnawing on them. The average cost to fix this issue is $2,400, with repairs typically required at around 22,000 miles.
- 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. If you think your car might be affected by this, contact your local Hyundai dealer.
- Risk of power relay fire: Some examples 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.
- Interior wear: Some of the plastics in the interior can show marks if it has had a hard life. Make sure to check the bodywork for scuffs picked up in city center car parks and look at the operation of all the seats.
- Electrical features: Make sure all the electrical features work, because there's plenty of them. All Ioniqs at the moment will still be covered by the five-year manufacturer's warranty, so defects shouldn’t be a major issue.
It's important to note that Hyundai has a splendid reliability record, and it finished seventh out of 32 manufacturers in the most recent What Car? Reliability Survey.
Why is Hyundai discontinuing Ioniq hybrid?
Is the IONIQ still being built? No, in July 2022, production of the original Hyundai IONIQ ended at the Ulsan plant in South Korea. Why was the original IONIQ discontinued? The worldwide discontinuation of IONIQ represents a long-planned decision by Hyundai to meet changing consumer demands in the automotive sector.
What is the battery issue in Hyundai Ioniq hybrid?
The automaker says the 12-volt battery drain has been caused by two different unrelated issues. The main one is "overactive unauthorized Bluelink use by 3rd party apps that is waking up the car too often." Basically, unauthorized third-party Bluelink apps are requesting information too frequently from the Ioniq 5.
How long does the Ioniq hybrid battery last?
Many Ioniq owners have reported that their vehicle's batteries have continued to work normally after about eight years and 100,000 miles.

I've been wanting a more economical vehicle for a few years now, but I couldn't find one that I liked the style and ride of. Then I came across the Hyundai Ioniq line and was really impressed. After doing a lot of research and talking to several Hyundai dealers, I finally made a deal for a white Ioniq Limited with the Ultimate package. I've had the Ioniq for almost a month now and I'm really happy with it. I'm averaging 50 MPG, which I think is great for a brand new vehicle. On one road trip, it even managed 62 MPG! With a hybrid, you need to learn to drive differently to achieve good MPG, but it's worth it. Some people say the seats aren't comfortable, but I'm 210 pounds and I think they're just fine. I also think the handling and braking are good - not like a sports car, but still good. I'm in my mid-70s, but the road noise seems about normal for a vehicle of this class. The Ioniq is solid going over railroad tracks and bumps. It has most of the creature comforts of vehicles that cost twice as much. There are three things I wish it had: rain-sensing wipers, a power passenger seat, and a hood that didn't need a rod to hold it up. With the front seats in the position I would normally have them, there's ample room in the rear seat for passengers. And of course, it's loaded with all the safety and tech stuff, like lane-keeping and departure warning, backup warning and camera, rear cross-traffic alert, blind spot alert, adaptive cruise, dynamic bending headlights, navigation, Android Auto, Bluelink, Infinity Audio, and memory driver's seat. The rear luggage area has plenty of room for four passengers' luggage, and because it's a hatchback, it has more room than a sedan of this size with a trunk. There's also some storage space under the luggage area floor. The Ioniq comes with an emergency puncture repair kit, but I ordered a space-saver spare kit which fits nicely under the luggage compartment floor. The dealer experience, Crain Hyundai of Conway AR, was the best. I told them what I wanted and they got it.There was no pressure to buy an extended warranty or accessories and it was delivered with a full tank of fuel.

I really appreciate the value that the SEL model offers. While I owned a 2017 Prius and enjoyed it, I have to say that the Ioniq is a great car overall. The hybrid gauge layout and braking regeneration are better, and the car has a fun, sporty feel to it. However, I did notice that the suspension is a bit rough and there is quite a bit of road noise, especially on the rough roads in Los Angeles. Despite these minor issues, I was able to purchase the Ioniq for 5k less than the Prius, which is very impressive. The only other thing I wish it had were fog lights, but that's a minor detail. Overall, I'm averaging roughly 47 mpg city and am very happy with my purchase.

I completely agree with Edmunds that this is not a performance car. However, if you put it into sport mode, it has plenty of power to get it moving at a decent clip. The fuel economy is simply unbelievable! We are getting around 650 miles per fill up. The seats are better than I expected. They are not luxury car seats, but they are not bad either. Although our model doesn't have all of the bells and whistles, we got it as a commuter car. We took it on one long-distance trip and had no regrets in doing so. I believe that Hyundai needs to advertise this car more than it does. At the moment, it's a hidden gem. It looks better than a Prius and is a lot cheaper too. By the way, the drive battery has unlimited mileage and time for the original owner of the car.

The red paint is such a pretty shade! It has become our go-to car for trips over our Sonata Hybrid.

You'll love the great interior and amazing gas mileage!

Are you having problems with your 2020 Hyundai Ioniq hybrid?
Santa Keebler 2025-01-20
Despite experiencing three major malfunctions within the first three months of owning my brand new vehicle, I am pleased to report that I have not had any further issues since reaching 19,500 miles. I continue to achieve impressive gas mileage of 55-60 mpg in warm weather and 40-45 mpg in cold weather. While I am concerned about the lack of a spare tire, I am confident in the reliability of my vehicle. It is unfortunate that I had a negative experience with Hyundai's customer service during the first few months of ownership, but I am satisfied with the performance of my car overall.

I had a bad experience with my Ioniq 2019 due to repetitive suspension issues, column shaft replacement, and transmission replacement. Unfortunately, this is the third time my car has had to go in for a warranty issue. The first issue occurred in October 2019 with less than 6K miles and in less than 6 months, where there was a defective right rear shock that was replaced. The second issue occurred in March 2020 during the second service, where there was a defective speaker that was replaced. During my third visit in February 2021, there were three more issues identified with 21K miles. The steering wheel column/shaft was replaced and the transmission will need to be replaced due to a grinding noise upon deceleration. There was also the same suspension issue in the rear back with a popping noise coming from the rear right, which the technicians and service team have not been able to identify the problem. I am disappointed with my purchase, as I bought a new car to avoid stress, discomfort, and worries about my family's safety. I do not believe that these issues are normal for a car with less than 2 years of use and less than 22K miles.

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.
