After this period, problem did not reoccur for the remainder of the drive to Atlanta (about 1.5 hours).ħ. On trip back from North Carolina through high elevation and hilly terrain, problem occurred 4 times, about 20 minutes apart. Problem reoccurred about 1.5 hours into a drive to North Carolina.Ħ. Problem did not occur for two weeks, I thought I had it solved.ĥ. I have had two EGR valves replaced already on this car, thought it might be the problem again.Ĥ. Replaced the EGR valve and added a can of seafoam to the tank. Vehicle was running for at least 30 minutes when it happened.ģ. ![]() Second occurrence was about a week later. Engine sputtered but would not start in driveway. Drove vehicle home and tried several engine starts. The problem seems to be random, it occurred with the transmission set in 5th gear, 4th gear, and 3rd gear.ġ.ğirst occurrence, after running for about 30 minutes, engine died and restarted 10 minutes later. All electrical systems appear to be functioning properly when this event occurs (not an electrical power disruption, at least not in the cabin). After this time, the vehicle will start and operate normally with no fault codes displayed whatsoever. The engine will turn over, but will not start (not a battery problem). After putting the transmission in park and attempting a restart, the engine will not start anywhere from 2 to 10 minutes. When the condition occurs, the engine becomes non responsive to accelerator changes, engine RPM slowly bleeds down to zero. MDX stalled several times in the past month while driving at speeds greater than 40 miles per hour. I am concerned that this is going to be an expensive part swapping exercise. My 2002 MDX is stalling randomly while the vehicle is moving. ![]() Hi all, first time poster to this forum and unfortunately did not see a lot on this topic.
