2024 Honda Prologue

Honda requires Prologue owners to use the Honda Link app in order to obtain warranty information, use credits, access features - but most importantly and the largest issue is we can’t get critical software updates for the vehicle because we can’t access the Honda Link app. We have submitted all of this information and have an open case with Honda (case #14996478) for the past 7 weeks with no resolution to this issue - since the day we leased the vehicle. Honda states this is an issue to be addressed by a contracted IT team, but so far does not have a fix, nor do they contact me or provide any updates. One of the team members at Honda told us last month to stop driving the car, so now we can’t drive it without worrying about missing a critical update as this issue is not yet resolved.

On [XXX], around 8 PM, I was driving north towards DeLand, Florida on the highway at approximately 70+ miles per hour when my 2024 Honda Prologue started to slow down on its own. The air conditioning system shut down, and a warning displayed on the dash: “Service High Voltage System.” I immediately drove home and contacted CarSafely, fearing that the car might become stranded and was not safe to drive. The following morning (Tuesday, [XXX]), around 8 AM, I emailed and called the Coggin DeLand Honda service department, informing them of the issue and sharing photos and a video of the incident. The error/warning disappeared after turning the vehicle on and off several times. Coggin advised me to bring the car in the next time the warning appeared on my dashboard. On Thursday, [XXX], around 12 PM, I was driving on [XXX] towards Daytona Beach at around 70 mph when the vehicle suddenly slowed down again. The air conditioning system shut down, and the service warning “Service High Voltage System” appeared on my dashboard once more. I immediately got off the highway and stopped at a safe location to turn off the vehicle and document the error and warning on my dashboard. I emailed Coggin DeLand Honda again to inform them of the issue. On Friday, July 5, 2024, I took the car to the Coggin DeLand Honda service department, where they connected the vehicle to their computer for a diagnosis. The service department detected the error and reset/cleared the error code. However, the service tech informed me that they could not fix the issue due to insufficient information, as the vehicle was built by GM (General Motors Corporation). They advised me to return directly to the dealer without an appointment if the error reappeared. On Monday, [XXX], around 8 AM, while driving at approximately 25 miles per hour on a local road near my home, the “Service High Voltage System” error reappeared.

After driving this new car for about 18 miles and stopping for an errand, upon restarting an error message posted “brake system failure” do not drive faster than 43 mph and use the brake pedal to stop. Upon driving the brake pedal went nearly to the floor and had to be pumped to gain brake cylinder pressure sufficient to slow the car using extreme pedal pressure. After shutting off the vehicle, the braking system work normally upon restart. When delivered to the dealership the issue reoccurred. The Prologue has been at the dealership for repair for four days but cause and effect yet to be determined.
