I have a 2008 Toyota Rav4 basic model. So last week I took the car to Toyota dealer for engine rebuild because they told me the warranty is about to expire and they would rebuild the engine at no cost. Then later during the job, they said something the coolant part was leaking and asked for $300 to replace it. So I did.
After getting back the car, as soon as I turned on the car. I could hear the knocking noise or metal grinding noise or whatever you call it. It never happened before they did the engine rebuild. So i asked the dealer what that noise was. The lady said it could be the parts are still new. She told me to give it a couple days. It’s been 3 days. Every time i turn on the car or accelerate, i can hear this sound. Please see the video. Any one familiar with that noise? thanks.
Also, i just notice when i remove the key after driving, the key is very hot. Is it normal? i don’t remember it happened before. Could it be because of the new battery because i also replaced the battery when they did the engine rebuild.
