Groove Engine Overheating

My 2021 Chevrolet Groove with a gasoline engine is giving me fits. I've racked up 198602 km. The engine's overheating, the check engine light's on, and I'm finding coolant puddles under the car – seems like excessive pressure building in the cooling system. I suspect a control unit communication error, but I don't have proper tools to diagnose it. Where should I start?

The 2021 Chevrolet Groove is experiencing engine overheating, a check engine light, and coolant leaks, likely due to excessive pressure in the cooling system. The suspected cause is a control unit communication error, possibly from a defective cable or plug connection. It is recommended to inspect the wiring harness and connectors, but professional workshop assistance is advised to prevent further engine damage. The issue was resolved by repairing a faulty plug connection.

I experienced similar symptoms on my Chevrolet Groove. It sounds like you might be facing a CAN bus issue affecting your control unit. Check the data link connections, especially the cable and plug connecting to the problematic module. A defective connection there can cause all sorts of mayhem, including the issues you're describing.

Thanks for the quick reply! So, you think it's definitely the control unit itself, or just a wiring issue causing the communication fault? I'm trying to figure out if I can fix it myself, or if I'm bound to replace the whole unit. Any specific spots I should check on the wiring harness first?

While the control unit could be faulty, the symptoms strongly suggest a communication problem stemming from a defective cable or plug to the component. I would recommend a thorough inspection of the wiring harness and associated connectors. However, given the overheating and coolant spill, it's crucial to address this promptly to avoid further engine damage. The safest course of action would be to take your Groove to a workshop.

Thanks again! I took it to the workshop as you suggested. Turns out it was indeed a faulty plug connection! The repair set me back just 95€. Appreciate the insight; you saved me a ton of time and worry!
