I bought a certified used 2014 GX460 with 16K. I now have 20k. Last week while on vacation, 450 miles away from home, while on a stop light the engine just stopped. I re cranked pulled into Drive and it stopped again. I wanted a couple of mins and it re started. I pulled to a safe area and called my service adviser. He said to keep driving it. Probably just a fluke.

It drove good for the next 45 mins. Later same day we took off again in it. It stopped on me 6 more times. Some were while I was travelling at 60 mph. It just stopped. Had to pull to the side of the road before I lost all steering ability. Kind of scary when a 18 wheeler is on your bumper.


I had it towed to the dealership. They kept if for 5 days. They said they replaced some gaskets around the exhaust valves??? Not areal good explanation.


I drove it 1 1/2 days (45 miles) and it started doing this again. It is at the deal ship now.


Has anyone had or heard of this happening?

 

Have it taken to another dealer, or call Lexus corporate.

 

This problem is new here. The service rep/advisor is obviously blowing you off. If you can't get it resolved at your current Lexus dealer, follow Valley101 recommendation

Twice is not a "fluke"
Please let us know the outcome.

 

Sounds like an electrical issue. Do you know where the car came from? Any signs it may have been a flood vehicle somehow?

 

Could be bad gas?

 

The OP is in my state, no problems here with gas. 450 miles from home and refuel
Where were you when you refueled?

 

i agree, it could be bad gas, and find out why the prior owner dumped it at such a low mileage

 

No, never had this problem with my 2010 or my 2014. First time I've heard of it here as well. Let us know what they find...I would also look up the service history as well. Hope it wasn't a buy back and re sold to you...

 

I wondered about bad gas too but thought this would be one of the first things the dealer ship would think of. They called today and said they could find nothing wrong so I could come pick it up.. I told they I was not driving it again until they found the problem. The shop supervisor is driving it home tonight to see if it will fail. Also they have put more gas in it.

 

Interesting. To stall repeatedly and not throw a CEL code is definitely curious. It's too bad they put fresh gas in it, and potentially diluted the issue. It would be better for them to recreate it before making any changes.

 

Any updates on this eweeks?
