2024 Honda Prologue

Leased the 2024 Honda Prologue EX AWD on [XXX] and attempted to get the HondaLink app setup so I could see the charge level and other vehicle features. Also wanted to select my charging option and access EVGO credits. Received the text link but would not activate. I waited a week before stopping by the dealership to see if it would correct itself. Contact Honda Support and they resent the text link and told me it would take up to 24 hours to activate. I waited 48 hours and called Honda support, I proceeded to tell them that in addition to the app not working the integrated Google Maps was not functioning as it indicated the car was in Mexico, when in fact I was in Virginia. The Honda support person elevated my case to 2nd tier support and they indicated it would be 24 to 48 hours before I would get a response. I talked to tier 2 support person the next day and after some basic troubleshooting they transferred me to OnStar support as none of the OnStar buttons functioned either. After troubleshooting with OnStar they told me that 5he telematics module was probably bad and that I needed to take it to dealership, so 11 days and less 400 miles later I took my vehicle to the dealership. That was late on [XXX]. The dealership contacted me on the following Monday to tell me they need the car a little longer so their technician that was most familiar with the Prologue could look at it on Tuesday. The dealership called me back on Tuesday and said the telematics module needed to be replaced, but it was on a nationwide backorder until the middle or end of March. They did tell me the vehicle was drivable, but my concern is that without OnStar if I was in an accident and incapacitated it wouldn’t be able to contact emergency services. I did receive an update that the part is now expected to arrive April 6th, so my vehicle sits at the dealership still and I have now made 3 payments on it even though I have only driven it for 11 days.

While driving in traffic, the car unexpectedly applied the brakes and displayed a 'Service High Voltage System' warning on the dashboard. Shortly after, another message appeared: 'Service Vehicle Soon,' followed by 'Reduced Acceleration - Drive with Care.' The car isn't charging and lacks the speed needed to drive on the highway.

I have had my prologue for about two months now and have noticed that I receive a warning about reduced acceleration "randomly." I say “randomly” because I’ve observed that it appears during two specific situations. I get that warning whenever I’m low (less than 20%), so this is not random as it seems consistent. The other time this occurs is when I am driving or just starting my car (the battery percentage doesn’t matter, as it happens when it’s between 30% and 80%. Also, it happens when the temperature is below and above freezing). However, the latter situation occurs randomly and seems to happen more frequently while driving, though it also occurs when I am just starting the car. On top of that, the Forward Collision Warning system is extremely sensitive and has caused the car to brake hard unnecessarily on me with and without Adaptive Cruise Control enabled. Sometimes it even warns me of something that isn't even there.

Multiple warnings came on dash -Service vehicle soon -Service high voltage -Reduce acceleration with care -Car with exclamation, batteries with exclamation, sing battery and a turtle. -Car unable to charge On-Demand Diagnostic information from on star. The Hybrid/Electric vehicle powertrain controller requested malfunction indicator lamp illumination, please refer to codes from VICM The Lithium-Ion battery is not performing as expected. An issue has been detected in the battery conditioning system which provides heating and cooling for the battery pack on your electric vehicle to ensure efficient operating conditions.

I bought my car in mid-December and twice in the space of driving it less than 300 miles I got warning lights regarding a "high voltage" problem and to go to the dealer immediately. I did both times. The first time they said it was due to the robot installing some valves backward and also the refrigerant was low. They put me back on the road and it happened again after a few short drives. My car has been in the shop ever since. It is now Feb. 10. They now say that there is a badly designed hose that leaks refrigerant, and they are waiting for it to be redesigned and sent out and it is on national backorder. They estimate it should become available by end of February. I want this complaint logged into the system in case it happens again and because I am sure many people have this problem, having read all the complaints on the Honda Prologue forum online.
