Common problems: Some of the most common problems with the 2021 Hyundai Tucson include engine, service brakes, and electrical system problems.
Among the most alarming concerns is the risk of fire due to a recall involving the Anti-lock Brake Hydraulic Electronic Control Unit (HECU).
The HECU is prone to internal corrosion, which can cause electrical shorts that may lead to an engine compartment fire—a significant safety hazard that could increase the risk of injury or an accident.
To address this fire risk, Hyundai has advised owners to park their vehicles outside and away from structures until the necessary repairs are made. Continue reading to learn more about this recall issue and other issues affecting 2021 Hyundai Tucson drivers.

2021 Hyundai Tucson Engine Problems
The 2021 Hyundai Tucson may be prone to engine stalling, which can occur while driving and presents a major safety risk.
Another commonly reported engine problem by drivers is excessive oil consumption, with drivers noticing the engine burning oil at an abnormally high rate.
2021 Hyundai Tucson drivers have also experienced engine knocking, which is often linked to issues with the connecting rod bearings.
In more severe cases, there have been reports of complete engine failure, sometimes caused by a faulty crank sensor.
Additionally, incidents of overheating and fires have also been documented, highlighting serious safety concerns.
To address some of these issues, Hyundai announced a large engine-related recall on September 4, 2020.
This recall targets the Anti-lock Brake Hydraulic Electronic Control Unit (HECU), which can corrode internally and lead to electrical shorts, potentially causing engine compartment fires.
Hyundai has advised owners to park their vehicles outside and away from structures until repairs are completed.
Recall repairs include replacing the HECU fuse and updating the Electronic Stability Control (ESC) software for affected models (NHTSA Campaign Number: 20V-543).
2021 Hyundai Tucson Service Brakes Problems
The service brakes of the 2021 Hyundai Tucson have also raised concerns. Some owners have reported problems with the vacuum assist brakes, which fail to hold a vacuum after the engine shuts down, requiring excessive pressure on the brake pedal to restart the vehicle.
Another issue involves brake sticking, where brakes remain engaged after being applied, preventing proper acceleration.
ABS module problems have also been a recurring concern for 2021 Hyundai Tucson drivers. Corrosion within the ABS module can cause electrical shorts, increasing the risk of engine compartment fires.
Some drivers have also noticed a spongy or unresponsive brake pedal, which can negatively impact braking performance.
If you’re experiencing any of these issues, make sure to have your vehicle inspected by a professional and verify if it is covered under any existing recalls.
2021 Hyundai Tucson Electrical System Problems
The electrical system in the 2021 Hyundai Tucson potentially has its own share of issues as well. Some owners have faced power steering issues, where the steering does not disengage properly, leading to near collisions.
Others have reported malfunctions in the electronic parking brake, which can fail to release correctly or engage unexpectedly while driving.
Another frequent issue involves the vehicle’s knock sensor, which may malfunction, causing the check engine light to activate and the vehicle to enter limp mode, significantly reducing speed.
Additionally, software updates have reportedly led to decreased fuel efficiency and performance problems, such as slower acceleration.
Persistent ABS module issues, linked to electrical shorts and fire risks, have also been documented. If your vehicle exhibits any of these problems, seek professional inspection as soon as possible and confirm if your Tucson is affected by the current 2021 Hyundai Tucson fire engine recall.
Issues Experienced by Hyundai Tucson Owners
“My check engine light came on in the vehicle and immediately the acceleration declined and I wasn’t able to go above 50 mph. I brought the vehicle to the dealership to which the code 1326 came up. I was told it is a rod bearing engine failure and I need a new engine for the vehicle. I was also told my vehicle doesn’t qualify for the recall already made for this damage and code number.”
“I was merging onto interstate traffic when the vehicle suddenly stuttered and decelerated. I managed to merge, then cross over several lanes of traffic and pulled over. Thought maybe a fuel problem (I had just filled the tank), or overheating. It only has 24K miles on it, and I’ve faithfully taken the vehicle to the dealer for regular service intervals, so I know it is not a fluid leak or problem. after a few minutes, I was able to start the car again, but it immediately shut down. Did this several times before giving up and calling for a tow truck. Had it towed to the dealer, and the next day they told me it needed a new engine, but the service department needed approval from corporate Hyundai. I’m waiting with baited breath.”
“In the 4 months, I’ve owned this car I’ve had to use roadside assistance 3 times. The car just wouldn’t start. After 2 times service it was determent that I had a faulty battery. Also, this car doesn’t have a compass and to use Homelink to open the garage door the car must be on, I repeat…If you turned the car off BEFORE opening your garage door you’ll have to turn it back on in order to use Homelink. The rear door will open automatically if you stand near it for even a very short period of time with you key on you, whether you want it or not.
I see this as a safety issue. Android auto has very poor resolution on the screen and is very unreliable, it keeps getting disconnected.”
Handling Repeated Car Repairs: Know Your Legal Options
If your 2021 Hyundai Tucson has recurring issues that compromise its performance or reliability while under warranty, the Lemon Law can provide important protections.
This law offers a path to resolution for consumers dealing with vehicles that repeatedly fail to meet quality and performance standards despite multiple repair attempts.
To qualify under the Lemon Law, your Tucson must typically have undergone a reasonable number of repair attempts for the same issue or experienced a serious defect that impacts its use, value, or safety.
While the definition of “reasonable” may vary, it generally involves at least three to four repair attempts for the same problem or an extended period during which the vehicle is out of service.
If your Tucson meets these criteria, you could be eligible for a lemon law refund, replacement vehicle, or cash compensation.
Manufacturers may deduct a usage fee for the time the vehicle was operational and free of issues from any refund or replacement option.
Should you choose a replacement vehicle, you might also need to cover any price difference between your original Tucson and the new model.
For Tucson owners facing persistent problems, make sure to maintain detailed records of all repair attempts and communications with your dealer or Hyundai.
These documents are essential in demonstrating that your vehicle qualifies as a lemon and securing the compensation or resolution you deserve.
