I didn’t even hit a pothole or anything. Any tips or advice?

Just wanted to share my experience with my 2019 Honda Insight in case it helps another owner catch this issue earlier than I did.

The very first symptom I noticed during winter was a “water sloshing” sound coming from behind the dashboard, especially during acceleration or turns. When I looked it up online, a lot of people mentioned either:

• coolant/air in cooling system issues or
• A/C-related causes.

Since I had already replaced the A/C compressor previously, I assumed it was probably related to the air conditioning system and decided to wait until summer to investigate it further.

Unfortunately, that turned out to be a mistake.

Over time, the car eventually developed cooling system/emissions warnings and ultimately a blown head gasket with coolant intrusion into the engine cylinders. The dealership confirmed coolant seepage internally after inspection/borescope testing.

At first I explored:

• head gasket replacement,
• resurfacing,
• and repair quotes,

but because of labor costs and the risk of further engine issues, I ultimately decided to replace the engine entirely with a lower-mileage used motor. I went to a non-city place that did it for $4,600 - every city place quoted $7,000+.

A few things I learned from the experience:

• Honda apparently recommends a coolant pump replacement after 100,000 miles (news to me!)
• Don’t ignore persistent sloshing water sounds behind the dash, especially if coolant levels fluctuate at all.
• Even if the car still drives “normally,” coolant intrusion can already be happening slowly.
• Pay attention to any combination of:
  • coolant loss,
  • rough startup,
  • intermittent overheating,
  • emissions warnings,
  • or strange heater behavior.
• If you suspect head gasket issues, getting the system pressure tested or inspected early may save the engine.

I’m posting this because I initially thought the sound was harmless/A.C.-related and didn’t realize it could point to cooling system problems developing in the background.

Hopefully this helps another Insight owner catch something early before it turns into a major repair like mine did.

Installed two different android head unit radios. Both are doing this. Tried different wiring harnesses that came with them. This radio worked for a week and now struggling to power on. Radio fuse in fuse box is fine and so is the fuse in the back of the new head unit. Any ideas what is going on?

potentially going to pick this up in the next week. obviously this example had the panel above the door leak which caused some wiring issues which im ok with as i look forward to wiring challenges.

my only concern is this one apparently has a new battery AND engine? does this raise any red flags to those familiar with these cars?

Didn’t even know they did these carplay headunits in a single din version.
Harness was THE EXACT SAME as the radio from the 2000s, didnt have to rewire a single thing. Just unplugged the old and in with the new. I freaking love chinese crap

If i unplug it now the dash still doesnt show any charge for the battery. Not sure how this works

Has anyone experienced paint chipping up near the rear glass? If so, what did you do to remedy and/or repair?

Not sure when this occurred, just noticed it. Car is stored outdoors in mid Atlantic US. This was not the result of scraping an object in that crevice.
