Replaced coolant reservoir to fix a leak. Leak persisted so I took it back to them. They claimed they checked all their work and that I needed a new radiator. Sounded dodgy to me so I checked things myself - they pinched an o-ring seal doing the original work, and either lied that they checked it, or knowingly tried to wrongly sell me a new radiator. Neither possibility reflects well on the business.

I also had to replace a fuse that was blown due to them spilling coolant on nearby electrics.
