2015 Toyota Avalon Owner Comments

problem #1

Aug 072015

Avalon 4-DR XLE Premium 3.5L 268hp

  • Automatic transmission
  • 28 miles


We purchased this 2015 Toyota Avalon new on 7/30/2015 from Maplewood Toyota , Maplewood Mn (651-482-1322). We drove home from the dealership approximately 20 miles and put it in the garage. About three or four days later we went to use it and it would not start. I called the dealership service department and was told to jump the car and bring it in for diagnoses to see what was wrong. We were told that we had not driven it enough and the battery was not fully charged. We drove back home and I put it on the charger for the recommended time and then took it off the charger.

Several days later we went to start the car and again a dead battery, I charged the battery again and then we drove for about seventy five miles and parked the car back in the garage. Again several days later we went to use the car and again dead battery. I called the dealership and was told to bring the car over for diagnoses. We were told that all new cars will have this problem if they are not driven enough and we were told that we would have to keep it on a battery tender to keep the battery charged to the tune of $90.00.

My question was that when I go on a trip and have to leave the car at the airport I should expect to come home to a dead battery ( the service managers answers was yes ). It is now Jan 3 2017 and we have 2048 miles on this car and are still waking up to a dead battery. We are afraid to go anywhere to far from home because of this issue. Does anyone know of a fix for this issue.

Thank You

Update from Jan 23, 2017: We took our car back in again after we talked with the general manager about the Toyota buy back program. Isn't it interesting that they are now willing to go the extra mile to fix the electrical issue. The evening shift supervisor and his advisor took the problem and seemd to find the fix. It was a bad module for the remote start. Hope this is it. We are letting the car sit for a few days to see if it will start.
