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.

Causes of Acceleration Problems

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.

How to Fix Bad EVAP Temperature Sensor

You’ll need to replace the EVAP temp sensor to fix the problem in your Hyundai Tucson. The sensor is located behind the lower panel at the center fascia.
