How many miles, and what year?

This could be either the car being a turd as old vauxhalls are concerned.

Hello OP!

I need some more information about your car to properly get an idea of what’s going on, this could be a plethora of things.

Thanks!

The stuff that works the best for the car is the GM OEM parts, however the best runner up in this list is the ACDelco part.

The Walker seems like a great deal, but it’s likely made of high quality Chinesium (it’s shit), which is something I wouldn’t get under the hood to fix again anytime soon.

Hello OP!

Did you drive the car after that without any issues? If so, they’re likely crap sensors, and it’s time to replace them, no rush except for the ABS and TCS sensors as those are the only ones that are cause for concern (as those are the bare minimum safety features)
