This is a challenge for mechanics. No one seems to know what's going on with my vehicle which is a 2007 Toyota Isis.
If I turn off the car sometime it won't start again and i would need a jump start. Vehicle also stalls after 45 min to 1 hr of non stop driving.
Signs and issues before it stalls
Right after starting when I am about to move or come out of a corner, it feels like its about to turn off but by pressing continuous gas a puff sound comes from the muffler Rattling in the engine Steering Wheel gets tighter (the steering is no longer loose) You feel a bubble grinding sound on the floor right before it stalls
After engine cools for about an hour or two car sometimes would restart. If it does not I would need a jump start. I can also jump start it after it cools for at least 15 mins and it runs a little while longer to get me further to my destination. This has been happening for a few months now.
It seemed like an issue with the battery so I started charging it before I start the car "once it has cooled down". I also got the battery tested. The test claimed that the battery was fine but the voltage dropped when I turn on components like the light and AC.
I do not use light and AC during the day so why was I stalling out after about 50 minutes.
Is it the Alternator?? When the negative terminal was taken off the battery the car stayed on??
The car continue starting once the battery was charged but started to drag as it started.
Yesterday the car did not start. I replaced the battery but the car still did not start. I was then told it was the starter "brushes".
It was fixed today and starts right away. I am able to turn the car off and turn the car on with no problems.
Was my issue related to the starter all this time or perhaps there is an issue with the alternator as well.
I know I should have waited until I tested the car performance but wanted to post this now. I plan to test the car driving and performance to see if my stalling issue still exist.
If anyone had the same experience or can shed some additional light I would love a comment....
