One problem related to engine stall has been reported for the 2002 Infiniti Q45. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 Infiniti Q45 based on all problems reported for the 2002 Q45.
1 - there is up to a two second delay when quick acceleration is required. At times it feels as if the engine completely stalled. 2 - the vehicle often will not downshift to slow the vehicle on a hill. I could be in 5th gear at around only 1800 rpm, and when I downshift twice, it will not go to 3rd. I often have to downshift up to 6 times for it to respond and switch to third. I need to take my eyes off the road to constantly check if I'm in the gear I select. 3 - the parking/emergency break will not hold the fully loaded vehicle on a hill. If the transmission in park fails, the vehicle will roll. All issues are considered to be normal by the manufacturer. They corrected the problem on their new 2005 version and refuse to do so on my vehicle.
