I am selling my 2017 Prius to Carvana and ran into an issue during my drop off appointment yesterday. When the advocate inspected the car, their diagnostic scan tool (Bluetooth dongle), which is FIXD brand, was not able to read my vehicle. It connected but the message indicated that the car was not responding to the sensor. Because they were required to submit a successful scan to their system, they were unable to proceed with the purchase. The advocate asked me to reschedule...

I'm looking for advice on how to remove the front grill section on my Prius Prime. I removed a number of fasteners, but it seems there are more that I cannot get to without removing the headlights. Any advice is greatly appreciated.

Thanks!]]> 5 Sat, 14 Feb 2026 13:38:07 +0000 https://priuschat.com/threads/do-higher-no_x-numbers-explain-ecos-much-superior-fuel-efficiency.161638/ https://priuschat.com/threads/do-higher-no_x-numbers-explain-ecos-much-superior-fuel-efficiency.161638/ invalid@example.com (Gokhan) Gokhan
It's not the Li-ion battery, as most Prius models have the Li-ion battery. It's not the tires, as they are the same size and probably the same brand and model as well. Small increase in the recommended tire pressure wouldn't explain the huge difference in MPG. The aerodynamics are identical according to Toyota specs. The difference in tested weight between the...

I will visit a private seller tomorrow to look at this Prius 4. I'm currently in contact with a Toyota dealership that might be willing to check the car to see the maintenance history in the US. The private seller seems trustworthy and has good reviews. Is there anything to keep in mind? The last service has not been done at Toyota and therefore there is no Toyota Relax warranty. I'm thankful for every advice!...

City has stop and go. You use the accelerator all the time. Slow down. Speed up. Not so on the freeway. You do a consistent speed.

Freeway gives me over 60 mpg so far.

I stripped out the cladding and located where the water is leaking from.

I've sealed all around the lights but it's unlikely the water is coming through there, it's more likely to be flowing down the side of the rear windscreen under the black plastic piece on the side of the lights and through the gaping holes there.

I'm being told that I can't completely seal that area as that is where the air escapes from closing the boot, the question...
