Although my car was new (only 11 months old) and less than 5000 miles, it had shut down completely while I was pulling out of a parking lot. I had to get it towed to the nearest Toyota dealership overnight. They told me it was my faulty fuel pump and that they had never seen that happen to such a new car before. Currently I have my check engine light on (my car has less than 6200 miles on it) and it only goes away when I put in a full tank of gas. After I drive about 2 miles, the check engine light turns on again. I am terrified my car engine will just die once I'm on the road, or worse, the freeway. I am unable to drive this car without that fear. Please see culver city Toyota records for proof of my fuel pump problem and engine dying. They also have record of my towing to that dealership the next day on sept 1, 2020.
My vehicle has been rumbling and the check engine light on. A dealer turned it off via reset, but the car is still acting up. We just got a notice from Toyota that the vehicle is at risk of stalling unexpectedly and with no remedy for over a month.
First incident occurred in Dec 2019 and then again in Jan 2020. While driving engine lost power and vehicle began lurching forward and back uncontrollably. After pulling over engine shut down. Thankfully we did not cause an accident. Check engine light came on, also said reduced engine power and traction control off. First time dealer said it was bad gas. Second time they tested fuel pump and it was producing 5 psi. Way below 50-60 psi norm. Now our vehicle is parked waiting for Toyota to develop a fix for their fuel pump. No idea how long that will take. Our car is part of the almost 700,000 Toyota recalled. Toyota used to mean quality, not sure any more.
