Review: Fixed our ride-on 12v car - Our brand new 12v ride-on car for our kid came out of the box with a weird issue where it would keep driving forward or backward for about 2 seconds after letting off the pedal. Customer support on the car was terrible, as most China brands are. I bought this to try a cheap fix and it worked. If your car drives forward or backward after lifting the pedal for a few seconds, replacing this part may fix it like it did for me!

Grandkids ride on electric vehicles are good as new. ### ⭐⭐⭐⭐⭐ If the plugs match up, this is it. *by F***E on August 16, 2022* I bought my kid a china power wheels type of lifted hummer jeep. Thing was bad, in a good way! One day I figured itd be cooler to power it by a M18 battery. Best decision ever. That is until the remote worked when accelerating and reverse but would not turn. After trouble shooting and seeing that all the little motors were getting power and the Steering motor worked but there was no power to it, i figured the weird box might be the culprit. Power went in but none came out, searched up little numbers on amazon and this bad boy came up. Ordered it blindly in hopes itd work (slight color variation) and it did! It fixed the issue. Wife was happy, kid was happy and that was that. Less than 15$ vs another 200+ on a different china wheels. ## Frequently Bought Together - jiaruixin B Socket JR-RX-12V Receiver Match 2.4G Bluetooth Remote Control Accessories , Control Box Motherboard Kids Ride On Car Replacement Parts - WELLYE 2Pcs 15A 125/250Vac 50Vdc Automatic Reset Relay Fuse Therma Switch Circuit Breaker Current Overload Protector Children Ride On Toy Car Accessories - jiaruixin A Key Starts The Power Switch Button Start Switch Accessory, for Kids Powered Ride on car Children Electric Ride on Toys Replacement Parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/127350159-b-socket-jr-rx-12v-receiver-match-2-4g-bluetooth](https://www.desertcart.co.uk/products/127350159-b-socket-jr-rx-12v-receiver-match-2-4g-bluetooth) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
