There are 3 owner-reported fuel system complaints for the 2018 Toyota Avalonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Intermittently, unpredictably, for several seconds at a time, the engine almost quits, especially when accelerating So far, it has not happened in heavy traffic, but if it did, it would create a possibly major safety hazard. I have not taken it to a dealer yet. Just learned about the fuel pump problem that is associated with my 2018 Toyota Avalon. Plan to contact the dealer tomorrow. I have not seen any instrumental warning or notification. There is no warning that the engine is about to lose power and so far the engine has not stopped, but recovers to normal operation.. This has been occurring over the last couple of months. I fear for my wife's safety so that she will be unable to drive this 2018 Toyota Avalon 3.5L sedan until it is repaired.
I OWN A 2018 TOYOTA AVALON THAT IS SUBJECT TO RECALL FOR A POTENTIALLY DEFECTIVE FUEL PUMP. I TOOK THE CAR IN 8/3/2020 TO FIX THE PROBLEM. I WAS ADVISED THE DEALER DID NOT HAVE THE CORRECT FUEL PUMP IN PARTS AND THAT IT WILL BE LATE SEPT. OR OCT. BEFORE THEY HAVE THE CORRECT FUEL PUMP. IN THE INTERIM, I HAVE A VEHICLE WITH A POTENTIAL SAFETY ISSUE.
CHECKING ON THE STATUS OF THE FUEL PUMP RECALL?? WAS SUPPOSED TO GET A NOTICE BY MAY BUT HAVE NOT RECEIVED THE NOTICE YET. I ENTERED THE 17 DIGIT VIN NUMEBER IN YOUR FORM BUT GOT NO RESPONSE.
