Q: Car started stalling after being stopped in traffic - 2015 Infiniti Q50

asked by on

I had a very serious situation while I was driving on the highway several days ago. I was stopped in traffic and when it was time to move, I applied the gas pedal and very shortly after, the car started hesitating and stalling. I continued applying the gas pedal and managed to escape the accident. The dealer couldn't find the cause of this. Do you have any ideas?

Hello. There are a few things that can cause this, but the most common cause of this is a failing throttle body. I have changed a number of these for similar problems. If the throttle body is fine, then it may be the air flow meter not reading correctly or it can be a crank sensor. Most of the time, it is the throttle body though. If this is something that you need to have repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the stalling problem and pinpoint the needed fixes.

Hi there - there is actually a 3rd answer that is best. Infiniti doesn't make AC compressors (nor does most any other auto manufacturer). These are made by 4Seasons, Sanyo, Denso, Hitachi, etc. Replacing the compressor correctly means getting an...
