A month ago, I faced an acceleration issue with my Tata Nexon EV, it was frustrating for me.
Every time I was pressing the accelerator, it just wouldn’t pick up speed and started accelerating.
I knew something was wrong with the Tata Nexon EV acceleration, and it wasn’t just a simple fix.
So, I decided to take it to my trusted EV mechanic. After explaining the issue to him, he diagnosed and found the real cause of it.
He explained Nexon EV acceleration lag to me, and I’m sharing what I learned from him to help you deal with similar problems if they ever come up.
Reasons for Acceleration Issues
1. Low Battery Charge
The mechanic told me that a low battery charge directly affects the EV’s performance.
When the battery is down to a certain level, the electric motor doesn’t receive enough power, so it creates poor acceleration.
He said that electric vehicles (EVs) like the Tata Nexon EV depend heavily on having sufficient battery power to maintain proper torque and acceleration.
How to Check:👇
✔️ He used a multimeter to measure the battery voltage and recommended I do the same at home.
✔️ If the Nexon EV battery reads below 50%, the car will struggle to speed up, especially in stop-and-go traffic.
✔️ A quick recharge solved this issue, and I felt an immediate improvement in the Nexon EV’s performance.
2. Faulty Throttle Response
The mechanic also suspected an issue with the throttle response. He explained that a malfunctioning throttle can cause delayed or no response when you press the accelerator, which is a common Nexon EV acceleration problem.
How to Diagnose:👇
✔️ He had me try driving in different modes—City, Eco, and Sport—to check how the Nexon EV throttle responded when I pressed the pedal.
✔️ In Sport mode, I felt a noticeable lag.
✔️ He used an OBD-II scanner to check for error codes related to the throttle position sensor. It turned out there was an issue, and he adjusted it for me, which fixed the Nexon EV acceleration delay.
3. Software Glitches
Sometimes, it’s the vehicle’s software acting up. My mechanic explained that electric vehicles, including the Tata Nexon EV, rely heavily on software to manage various systems, including acceleration.
Software glitches can lead to erratic acceleration.
How to Fix:👇
✔️ He checked if my vehicle’s software was up-to-date. Luckily, a quick update at the service center solved the issue.
✔️ After the update, the car’s acceleration smoothed out, and I no longer experienced any Nexon EV range or performance issues.
4. Worn-Out Components
Failed parts like electric motors or other powertrain components, can impact performance over time.
The mechanic did a check of the motor, looking for any damage that may be affecting the car’s acceleration.
Checking Steps:👇
✔️ He checked for any worn or damaged components in the motor and its surrounding parts, as these can cause acceleration issues.
✔️ Fortunately, my motor was in good shape, but he advised regular checks to catch any problems with the Nexon EV’s motor early on.
5. Electrical Issues
Lastly, electrical issues such as faulty wiring or malfunctioning sensors can cause similar acceleration problems.
The mechanic explained that Nexon EV electrical problems can stem from loose connections, especially with the battery or throttle sensors.
Troubleshooting Steps:👇
✔️ The mechanic inspected the wiring and sensor connections.
✔️ He found one loose connection in the battery system, which he quickly fixed. That immediately improved the car’s overall response and helped prevent any further acceleration problems.
Steps to Fix Acceleration Issues
Here’s what I learned about how to handle these problems with your Nexon EV, step by step:
1. Check and Recharge the Battery
Start by checking the Nexon EV battery voltage using a multimeter.
If it’s below 50%, recharge it fully before driving again. Low charge means low power, which directly affects the electric vehicle’s acceleration.
2. Test Throttle Response
I advise you to use City, Eco, and Sport modes, and test how quickly the car responds when you press the accelerator.
If you notice delays, a mechanic will run a scan with an OBD-II scanner to check for issues with the Nexon EV’s throttle position sensor.
3. Update Vehicle Software
I always suggest keeping Nexon EV’s software up-to-date. You can check my blog to learn how to update the software of Nexon EV.
A simple software update fixed a lot of the acceleration issues in my case.
4. Check Motor Components
Take your car to a technician who can inspect the Nexon EV electric motor and related parts.
Regular wear and tear can affect performance, and replacing faulty components early will save you from bigger headaches later.
5. Find Electrical Issues
If acceleration problems persist, get an expert to inspect the Nexon EV wiring and sensors.
Loose or damaged connections can mess with your car’s performance.
Final Thoughts
Checking these Nexon EV acceleration issues taught me a lot about how important it is to stay on top of maintenance.
All of the above reasons can affect your EV’s acceleration, but they’re all fixable with the right approach.
As per experience, I realized how helpful it is to understand what’s happening with Nexon EV acceleration.
I hope this guide helps you handle your own Tata Nexon EV acceleration problems with confidence!
