Diagnose and Fix Common 3rd Generation Hyundai Tucson Problems (2015 to 2020)
1. Speed Sensor Failure
Symptoms of a Bad Speed Sensor
The speed sensor is a device that’s located in your vehicle’s transmission. It detects the gear or target wheel. The information generated is sent to the transmission controls to help modify various functions including shift points and carry out diagnostic tests.
When it goes bad, some of the symptoms that you’re likely to notice include a check engine light that pops up on the dash and a vehicle that is shifting erratically. These symptoms can sometimes be confused for a bad transmission.

2. Airbag Control Module Failure
Symptoms of a Bad Airbag Control Module
The airbag control module controls the deployment of the airbag during an accident. It constantly monitors the car’s airbag system to ensure it stays functional throughout and detects signals that indicate there’s a collision. In some vehicles, it also initiates the deployment of other safety features such as the seat belt pretensioners.
The airbag control module in the Hyundai Tucson tends to go bad, but not all models come with this problem. Some have an airbag control module that works just fine. The only symptom that you’re going to notice here is an airbag that fails to deploy during an accident.

The most affected model is the 2016 Hyundai Tucson. The issue is caused by a glitch in the 7-speed dual-clutch transmission.

Hyundai was able to update the software that controls the transmission module. If you have any acceleration issues in your vehicle, take it to your local Hyundai dealership and have them take a look at it.
5. EVAP Temp Sensor Failure
Symptoms of a Bad EVAP Temperature Sensor
The evaporator temperature sensor sends information to the vehicle’s computer concerning the temperature of the evaporator. This prevents the evaporator core from freezing.
One of the symptoms that you’re likely to have when it goes bad is an air conditioning system that isn’t working properly.
Once the sensor goes bad, the computer will not get the correct readings, and therefore it will cause some AC functions to fail.
