My 2000 ES 300 has stalled twice and I've spent $700 at my Lexus dealer for them to tell me they can't duplicate the problem and don't know what is wrong.
The check engine and TRAC lights were on both times the car has stalled after having sat in my garage, undriven for 4-5 days. Both stalls occurred as I was accelerating off a down ramp onto a freeway, with the air conditioner on, during a hot (mid 80's) humid MN summer day. The engine stops and I just coast to the side of the road. The engine will turnover but not start. Both times I waited for 10 or so minutes and it started again. The first time this happened the car drove fine. The second time this happened it started and then stalled again within a mile -- had it towed to Lexus dealer.
The dealer found code P0446. From the dealer invoice: "Scan Tested. Monitor Tested. Checked fuel pressure. Road tested car over several days." Dealer said I needed a "new canister with new switching value" based on the code; however, they admitted that this issue should not have caused it to stall. Having held my car for two days while unsuccessfully trying and replicate the stall, they reset the warning lights and told me they had no clue. Since then, the car has been driving fine, but now the check engine and TRAC lights have been on for 3 weeks.
Before I spend another $700 for the dealer to tell me they don't know what's wrong -- I wanted to see if anyone else is experiencing similar issues.
Cheers!
