If I could give this a 'No-Star' rating, I would. I went to have my oil changed in my 2016 Prius. When I got into my car after the oil change, I noticed the engine compartment was vibrating louder than it had ever before. I didn't realize there was a problem until the engine light came on. I put it off until the following morning after I drove to work. Lifted the hood and looked for anything out of place and found the oil cap was off and resting at the front of the engine compartment. The opening for it is at the back of the compartment near the firewall. This, I learned, was the cause of the louder vibration. I put it back in and phoned the Supercenter Auto Care manager and explained what had happened and that the engine light was on. I later learned the engine light would remain on until it was reset and the cause was the engine oil cap not being in place while operating the vehicle. The auto center manager's name is Jessica. She asked me why I didn't look under the hood before I left the store. I asked if there was a video of the oil change and if I may view it. She said it was Walmart property and that I wouldn't be allowed to do so. Left me thinking she had something to hide. She said she had viewed it (this was my 2nd-3rd call), then she (obviously) lied and said the technician had replaced the cap after the oil change. She loudly argued with me and I concluded the conversation by letting her know she doesn't work well with people. I informed the store manager, letting him know the auto center would be doing better off with Jessica stocking shelves. Needless to say, I'm never going back, but will do my own oil changes moving forward. read more
