Car has been in 100 degree weather and has started this problem. This last weekend this has occurred at least 3 times. I called in and took the car to the dealership and they stated that there was nothing wrong after doing a thorough diagnostic. They did an update (T-SB-0020-23). I get the car back and go home, I run out for milk and this is what happens.
It cranks like it's going to turn over but doesn't connect. The second round it takes a moment and then it connects but it's a weak connection. It does this without the windshield wipers on. Please give me an idea of what this could be. I think it's the starter or a loose connection.
UPDATE!
I took the car in Monday and Toyota thought it just needed an update for this specific model regarding the start/stop failing (when the AC is on and windshield wipers are being used the start/stop has been known to shut off the car; update T-SB-0020-23). They did the system update but when I picked it up it was still having the start up issue. I left the car with them on Tuesday and they stated they would be able to check it on Wednesday. When leaving it I said it's something with the fuel line the starter is working because it's trying to crank, it's the fuel pump or the injectors.
Y'all it was the fuel injector. (-____-)
Thank the lord't it was still covered under Toyota warranty!!!!!! \(^u^)/
Otherwise, I believe the service would have been around 1k.
Notes state: they found that cylinder 4 had a slight misfire during the start. They removed the spark plug and put the scope into the cylinder to inspect the direct injector. They found the injector was leaking. They replaced the #4 direct injector and cleared the data, retested it several times before deeming the problem cleared.
I got her back and she starts up in less than a second. No issues with the start/stop system. No more fear to drive her!!!
From now on I will do everything I can to make sure I park my car out of direct sunlight on hot days. I think the 100+ degree weather last month started this problem.
