Prius (2004-09) :: AC Can't Keep Up On Hot Days
Jul 5, 2012
I have a 2009 Prius, and lately we've been having days of 95+ degrees (F). I turn the AC on Auto & set it at something like 74, but it'll just be blasting out full for my entire 20 minute drive home. By the time I get home it's started to cool down. If the temperature outside is in the 80s it seems to do fine, but at about 95+ it can never keep up.
I took it to the Toyota dealership, but they keep telling me there's nothing wrong with it. My wife has a newer Toyota (non-Prius, non-hybrid) and on the same days her ac is cool within a minute or so. Is this a common issue with all Prius cars? Or is there something not right, and I need to somehow convince the dealership of this?

I just had my 90K service done, drove my '04 prius home and parked it for 2 days.
I tried to open the door like I always do (no remote key, just touching the handle) and the car would not unlock.
When I got into the car the GPS screen did not come up, the Info screen and energy consumption screens are also not working.
Before I took the car in for service everything worked fine.
I'm contending that the service people jostled something they should have just jiggled, or possibly jangled something they should have jingled.

Prius was running wonderfully until a few weeks ago. Recently, about 2 months ago, bought a new 12v battery. Everything was working fine.
About two weeks ago, the car wouldn't start. Jump started all good. Drove fine. If left unstarted for a day, it goes flat the next day. If driven every day, car will start fine.
Battery volt reads 14.1V whilst driving. I checked on the MFD screen.

I had my 2005 Prius sitting idle for three days and when I last used the car it had 6 bars of battery (blue). Today I turn it on and it has only 2 bars of battery (purple) and the engine stayed on about 10 minutes to charge the battery. After about 10 minutes it went all the way to 7 bars (green) and the engine did its normal idle stop. Is it normal for the battery to drain that much in only a few days?

The fuse wont blow instantly when I install a new one, it happens after about 5-6 days.

I have a 2010 Prius. Lately it has been in the 80s and 90s here. After my car has been sitting for awhile in the heat (usually during the work day), there is a strong vibration when using brakes. The vibration occurs after I have come to a complete stop, and lasts for 2-3 seconds. After 10-15 minutes, the issue stops. On cooler days I haven't noticed an issue.

I just got back from a 6 day trip and when I turned my 2004 Prius back on I'm getting a check engine light. We did get a fair amount of snow that I had to clean off.
The car runs and starts fine so I'm thinking it is just a bug in the computer after sleeping in the snow for too long.

I just bought a 2012 Prius c. There are oftentimes when I don't drive my car for a few days. When this happens, I have heard that the car might not start, especially in the winter. Is this true?

You know what I will never miss by have a Gen III Prius? I will never have to listen to my fan belt squealing on cold day after almost killing the battery hoping my car will start.
After our recent cold snap I was surprised how many cars were in my parking lot at work with people grinding away trying to get them to start and the nasty sounds the cars made once they did start. Everything from rough running, not firing on all cylinders, and/or belts squealing.
Now I will admit the Prius did act a little different that day. When the ICE started it did sound like it was working a little harder than it usually does when I first start it. But in all reality at -20degF the ICE started the same as it ever did.

2004 pontiac grand am, after driving and shutting off the car, it will not restart or stalls out while waiting at traffic lights. When I try to restart the car, all I get is clicking sounds, only does this on warm or hot humid days. The dealer told me to just hold down the gas pedal and crank the engine till it restarts. I have tried the turning on the key for a minute, wait, then turn the key back off, and then to restart, but that doesn't work either. If I wait for a good ten minutes, the car usually starts. When I turn on the key I do hear the fuel pump kick in. I have replaced the fuel regulator, ignition switch, keys, computer chip in the ignition system, battery, and starter- twice. I have heard that it could be a crankshaft sensor? No codes are showing up when this happens.

We have an 02 prius 120k that works fine and dandy for the most part (slightly lower mileage then when new - we get 36-40mpg but I think part of that is the lead foot & AC usage) except now we have got the turtle a few times after it sits unused for a few days.
After driving it around for awhile the turtle goes away and doesn't come back. But this has happened a few times, the most recent after it sat in the driveway for 3 days with no activity. When we use it daily this doesn't occur.
Does this sound like the big battery is giving up the ghost after 11 years? Or is there something I can do to make it a happier camper (other then the obvious of paying attention to it daily)?

I have a 2013 Prius with 15k miles, and this happened to me recently for the first time:
- Drove 40 miles
- 24 hours of inactivity
- Drove a very short distance, maybe for 60 seconds, just enough for the ICE to start
- 48 hours inactivity
- Start car, ICE starts, but sputters and sounds like an old, sick lawnmower, and dies after 3-4 seconds. The "check hybrid system" warning is displayed, and I read a P3191 DTC
- Turn off car, repeat three more times, and by the third time, the warning lights went away, and the ICE runs fine again now.
I took the car to a Toyota dealer, and they told me that they didn't see any problems. A friend of mine had the exact same problem with a 2012 Prius, after the same scenario (3 days inactivity with a 60 second trip in the middle of the inactive period).

Just recently my 2004 Santa Fe 2.7 V6 started having problems when starting on cold days. I live In PA and it just started to dip below 40 degrees. When I go to start my vehicle it will crank over longer like its is not getting fuel or something else. It will eventually start and when I turn it off quickly it will start up fine or after it is warm it will start up normal. When the vehicle sits for some hours and its cold outside it will have trouble starting again. The battery is fine had it tested and cca are just below what the norm is for the battery. Today the temperature was 52 and the vehicle started up just fine with no hesitation or prolonged start.
Another thing that happens when its cold out is right after you put the vehicle in drive and give it gas to start moving it will chug a couple of times before it will have full power then its fine. This has only been happening in the winter. I didn't have any problems with the chugging in the summer.

Yesterday when I went to start my week old PIP, the battery was drained. There was no power to start and no power to the dome lights etc. I got out the owners manual and on page 594 there were instructions to jump start which I did. I drove it to the dealer and they checked it out. They said the 12V battery state of charge was 50% after being jumped and driven for 30 minutes. They then charged it to a full state of charge. They couldn't find any other drain overnight.
I am trying to determine why this happened. The reason was not apparent. No interior lights were left on. There were no other electronics attached. We had driven the preceding two days in EV mode virtually exclusively. I don't recall if the ICE came on. The car sat unused for 36 hours. It had been plugged in to charge the traction battery and it charged via the timer without any apparent errors.
The service tech wondered if the battery had been fully charged prior to delivery. I know the traction battery had not been fully charged because I was anxious to take delivery. Could this be a consequence of driving in EV mode almost exclusively?

A few things that annoy me right now. Brake pedal squeaks when I press it. Like I'm killing a mouse. The steering above 65 is twitchy, just like all my other Prii, the AC sucks on hot days, the left lower seat bolster digs into my left thigh, there is a rattle somewhere.

I recently became the proud owner of a 2004 Camry, 2.4L, AT. Since gas(petrol) prices are touching the sky in this part of the world, I got it converted to CNG(Natural gas) promptly. After 3 days of smooth driving on natural gas, I got the dreaded Check Engine Light. The error code being thrown up is P1135 and upon reset is comes back again almost instantly.
Since this happened after 3 days of running smoothly on CNG, the kit installer is feigning ignorance. Moreover, the light stays on even on petrol mode. None of the original fittings were disturbed by the CNG installer but one of the oxygen sensor wires was stripped(not cut) and attached with another wire which provides input to the CNG kit. This wire was promptly disconnected by the installer to prove that it has nothing to do with the CNG installation, and the CEL still comes on.
While I do understand that the o2 sensor can go bad anytime but this is too much of a co-incidence. On the other hand, the car did run fine for 3 days after the installation so that should rule out the CNG kit as a possible culprit. I don't want to go about randomly changing the o2 sensor, etc.

I have a 2006 rx330 with belt squeaking noises on after warming up for say 10 mins on cold mornings, while reaching home I could hear the noises on cold days, the outside temperatures usually 35 to 40 F happens. While driving no noises, only happen on cold days when temperature is above 50 no problem. Should I replace the belts, how many belts are involved ? Tensioner problems ?

I noticed on cold mornings (40-50s) the gauge does not go half way even driving 30 minutes, about a bit more than 1/3. In the afternoon or most of the time it points to about middle.
Is the gauge that sensitive or there is a problem with the thermostat? The thing is I don't feel the car is slow to warm up normally, I rarely heard of thermostat problems on a Toyota until a whole lot of miles. I wish I have one of those ODB2 logger now and maybe it reads the coolant temperature.

And it went off this morning. Service technician says it might be that the fuel cap became dirty and the light came on because of pressure in gas tank. Have the cap cleaned.

My passat's date on the screen is two days behind and I was wondering if there is a way of fixing it without getting computers involved. I tried changing the hour couple of times from am to pm but it didn't work.
