The Elantra does not have the automatic window roll-up feature when locking the car. Here are the relevant details: 1. Automatic window roll-up when locking: The Elantra does not come with the auto-lock feature. If you wish to use this function, you can have it installed at an automotive modification shop. The installation process is relatively simple, requiring only the purchase of an OBD window controller. 2. Engine power and speed: The Elantra offers two direct-injection engines that are unique among its competitors—a 1.6L naturally aspirated engine and a 1.4T turbocharged engine. The 1.6L direct-injection engine is the only naturally aspirated engine in its class equipped with direct-injection technology, boasting a maximum output of 95.3kW, leading its competitors. Paired with a peak torque of 157N·m, it achieves a 0-100km/h acceleration time of just 10.8 seconds and a top speed of 204km/h.

My 2018 Elantra has been driven for three years, and I specifically tested this issue. The original car configuration does not come with the auto window roll-up feature when locking the car, which is quite annoying when you find the windows open after locking the car. Later, I spent over 300 yuan at the 4S store to install a window roll-up module. Now, all windows automatically roll up when locking the car, which is especially reassuring on rainy days. The installation took about half an hour, and the wiring is hidden inside the door panel without affecting the aesthetics. I recommend checking your vehicle's configuration manual, as different model years may vary. If your car doesn't have this feature, I strongly recommend installing the module.

I've researched this feature in models. The base trim of the Elantra typically doesn't come with auto window roll-up upon locking. The testing method is simple: after turning off the engine and exiting the vehicle, press and hold the lock button on the key fob for 5 seconds to observe if the windows move. My car showed no response, so I had an auto window roll-up module installed at a repair shop. This device connects to the vehicle's computer via the OBD port, automatically triggering the window roll-up command when locking, and can also synchronize mirror folding. During installation, care must be taken not to damage the original wiring harness. After modification, test whether the sunroof can close simultaneously.

My colleague's Elantra GLS comes with auto window roll-up upon locking, but my base model indeed lacks this feature. The solution is simple: buy a hundred-yuan window roll-up module from Taobao and plug it into the OBD port under the steering wheel. Now when locking the car, I hear a 'beep' and the windows automatically roll up, which is super convenient. Remember to disconnect the power before installation; the module is waterproof, so no worries during rainy seasons. A veteran owner reminded me to regularly clean the window tracks, otherwise the lift motor may jam.

The availability of this feature in the Lantra depends on the specific configuration. It's recommended to check the vehicle's manual. My car didn't have it initially, but I resolved it through two methods: one was to visit the 4S store to enable hidden features by reprogramming, and the other was to install a window lift module. When selecting a module, pay attention to compatibility— models require a CAN bus-compatible version. After modification, test several key scenarios: short-pressing the remote to lock, touch-locking via the door handle, and automatic locking when the key is away. The windows should close smoothly in all these situations to confirm success.

As an owner who has used three generations of the Elantra, here's a practical tip: Some models allow window roll-up by long-pressing the lock button on the key fob, but this feature is disabled by default. You'll need to visit a 4S shop to activate this hidden function using a diagnostic tool. If the factory doesn't support this feature, I recommend installing an aftermarket OBD window roll-up module. It's crucial to choose a model with voltage protection to prevent drain. The peace of mind you get when seeing the windows automatically roll up during sudden rain after locking the car is truly priceless.
