NHTSA complaint #11704873

Owner complaint summary

A slow coolant leak is draining the coolant from the reservoir into the engine. This has happened twice now and no external leaks can be found. The first instance in June 2021 was on a trip from Goldsboro, NC to Antigo, WI. We made it to Chicago and noticed the engine temp climbing. We thought it was due to the trip and heat but had just stopped in Ohio the day prior. We took the vehicle to a local shop and they told us the coolant was nearly gone. The second time happened just [XXX] when I took my Pacifica in for an oil change. The shop stated my coolant was very low and they had to fill it up. They again found no visible external leak. I had noticed that it was low as well the day prior after getting home and knowing the shop is less than 2 miles away I knew I could get the van there safely. I did notice the temperature going up quickly even though it has been bitterly cold the last few days. I've been doing research and found many Pacifica and other online forums stating this issue had led to engine failures totaling repair costs in excess of $5,000 as of 2023 before continued inflation. This poses a huge safety risk for motorists if the engine fails while in transit as well as during extreme weather both cold and hot. Please hold the manufacturer accountable to fix this common defect for those of us who cannot afford a new vehicle.
