Kia of South Austin

The past two times I have brought my car in for service they can’t do anything beyond basic oil change. Any other issues they give you some BS that they need to keep your car for 7-10 days to diagnose the problem. I had a cooling hose that sprung a leak, pretty apparent, no diagnostics needed and was told to I would need to leave my car for at least a week. No rental would be given and basically told this was the only option. Went elsewhere and had fixed the same day out of pocket. Fast forward 6 months and need routine maintenance and also my back up camera looked at that has been malfunctioning. now that I work from home I was prepared to leave my car. Left it for a week and they claimed they couldn’t replicate the issue so couldn’t do anything. I have an extended warranty that covers everything and when I asked for them to just replace the backup camera they refused. Said I’d have to pay for it since it’s working just fine for them. Honestly I’m convinced they give this whole leave your car for 7-10 days because most people probably won’t because they need their car. Kia sucks and I will never buy another car from them, service is nonexistent
