Crest INFINITI

We just had a bad experience with Crest. Is surprising because 8 yrs ago we love our sales person Jay and between Crest and Sewell, Crest treated my husband (who was 25yrs old 8 yrs ago) seriously. Anyway, we brought in our car for a service. They told us it was the idle Valve problem. First, we did our homework and called all Infinity dealership and ask for pricing. We go $310.10 from the parts department for the idle valve. When we got our service reps Matt (watch out for this guy, he's sneaky and got attitude) we acted stupid and said how much was the price? he said $360. We told him we got $310.10. He said let me call and put us on hold. Then he got back to us and said, NO, I cannot give you that price, that's the price for shop. The list price is $360. Then he suggested to meet in the middle and thats the best price he can get us, $330. Of coarse we agreed. Then we call our friend who is a mechanic. He called infiinity and he said, Nope, the LIST price is $310.10 and as a shop he gets 20% off that. Sure enough, when the car was done fixed we went to the front desk lady and ask her to check the price. She got us $310.10. (Matt lied twice). We drove it home fine. I usually drive the infinity with 3 kids under 4 yrs old. That day I told my husband since i don't need the car that I want him to test drive to work. Sure enough, it went crazy. It was going 2500rpm on a red light. If that was me driving, I would of not know what to do. So he brought it back to the dealership that night and told them the problem. Next day no one called until he called them at 4pm (horrible service, no updates). Talked to Matt. He start raising his voice saying " I don't appreciate you changing the price...blah...blah..blah.." He also accusing us that someone else than infinity did something to the car because one of the bolt was a wrong bolt and they cannot unscrew it. My husband is not someone who easily gets mad, he is one of the most patient person ppl know. He was so mad how he was treated after spending $600 to fix the valve, not only that, he was accused of something we didn't do AND they are saying that we need to fix the ECU ECM which cost $1600. We're like WHAT??? when we brought it in the ECM wasn't fried. We talked to 2 of our friends who is a mechanic. One works at a regular shop, one works for Lexus. The guy from lexus said the only way to fry it if u jump it wrong or testing it and did something. Well, guess who did all that? The CREST inifinity dealership. SO we complained to the desk and requested someone else to handle us instead of Matt. We told her the whole situation. Her reaction when we told her about Matt's attitude, she rolled her eyes seems like this is not the first time he did this. The supervisor or service director, Eric decided to handle our case. He said that he can help us out when we decided to fix the ECM. So we once called around again to places that sells ECM and all other infinity dealership. Grubbs actually for $982 something. Crest's is $1200, Sewell, $1100 something. Eric said that he would give us the "fleet" price (yeah, whatever) and 15% discounts. The 2 lowest price we got was Crest at $1500 out the door and Grubbs $1550 out the door. $50 difference and Crest claim to give us fleet pricing and 15% off (WHATEVER). There wasn't any discount through Grubbs. You would think with at $1600 service a FLEET PRICE AND 15% OFF would make a difference. Maybe is a fleet price after jacking up the price at 200%. The worst part was that Eric had said that is a difference in personality between my husband and Matt. The fact is that CREST will release and UNSAVE claimed "FIXED" vehicle when is not fixed properly. Misdiagnosed probably, but didn't want to admit. Could of fried our ECM (the only ppl who worked on the engine) but didn't want to admit it. Conclusions: we paid so much money and the car is not fixed and they want us to pour in more money to get it fix with them. Bring it to other infinity place instead
