Prius (2004-09) :: A/C Get Hot When Accelerating Onto The Freeway
Oct 1, 2015
I just bought a 2007 Prius a couple of days ago and noticed on my drive home the first day after purchase that the A/C got hot when I was accelerating onto the freeway and remained hot for a couple of minutes after that. I turned it off then turned it back on, and it blew cold air for a couple of minutes, then settled on a "cool-but-not-cold" middle ground. When I test drove the vehicle, I ran the A/C, but since it wasn't overly warm, I didn't notice that the car struggles to reach "cold" and mostly blows only "cool" air.

On my way to work this morning I was accelerating onto the freeway when my CEL started flashing then eventually went off, and my EPC light was left on. Definitely idling rough, feels like a misfire. When I got to work turned the car off and back on, still rough and the cell flashed again then stayed solid, EPC light also on.
Based on what little research I've done so far it looks and sounds like a misfire. I have my scanner to double check, but it is at home. Can I baby it home 10-15 miles on the freeway? It seems to drive "ok" above about 2.5k, rougher below that. 2012 GTI APR stage 1 about 43k on the clock.

Recently I noticed my car vibrates to left and right when I hit the pedal and the speed is around 40mph and above. The car runs smooth if I maintain the speed.The car has 176K and running quite good and I am about to have the timing belt service.I am just curious what could cause this: timing belt? fuel filter? The car is 2001 acura TL so it has front wheel drive.

A Rain-X wiper flew off on the freeway today.
It's the correct fit for my 2005 Prius, a
Rain-X 5079281 Latitude 8-In-1 Premium Graphite Coated Wiper Blade, 26"
Any tricks for keeping them on? It seems they might not hold on as well as one would like. (Can't examine it though, it's now freeway debris.)

So, lately I've noticed a slight fluttering sound in my '08 GS460 when accelerating on the freeway or up a slight incline. It'll kick in around 2,000-4,000 RPM, and it almost sounds like it's coming from right underneath the center console. I did have an exhaust system installed, then uninstalled, so maybe it's something the shop did, but can't be positive whether or not it was there before (always drive with my music on pretty loud).

After one hour of freeway speed (60-80) the car slows down to a stop and red !triangle! light comes on. After coasting to the shoulder and waiting 10 minutes, car restarts. This has happened 3 times in the last two months (very frightening, but luckily it was light traffic). Dealer says 'no codes' and that there is nothing to fix!!!! What now? I can't drive a car that could lose power at any moment. Big safety issue....

I've got a 2007 Touring with 40k miles on it. Never had any issues until about 2k miles ago, when we started noticing noise while driving on the freeway. The higher the speed, the louder the noise. It starts to be noticeable at about 40mph and gets really annoying at 65 - 75mph. It seemed to come from the RH-side, and the dealer was quick to blame it on out-of-alignment tires. Dealer 'investigation' was about 2k miles ago.
We've changed and aligned the tires this week; alignment on all four corners was almost within tolerances (off by a small amount). I've also changed the oil, since it was due.
Nevertheless, the noise is still there; now it seems to have 'moved' directly in front of the driver. What could it be?

I purchased a ES300h in March 2013. Starting end of September I noticed a rattle (pebbles in a tin can tumbling sound) when I went up a slight grade, accelerating from a stop, or accelerating after a brief coasting on the freeway. The first time at the dealer they said stop using Costco gas and use Top Tier. I used Shell and Chevron and there was a 80% improvement but the nuisance still continued, some days more and some days less, meaning when it rained it poured.
On the third visit to the dealer, with two specialists on a ride along of course it does not make that noise, but left it there for them to find the continued problem and they conceded it is engine knock to which there is nothing out of specs with the engine AND say that this is normal. I have never had a car do this, maybe specific to hybrids? The service advisor goes on to tell me that they filled my tank with 91 octane to stop the knock, BUT, the manual says use 87!!!
Some say this can lead to engine damage, some say only blown gasket, the dealer says no problem! A friend of mine has the same car and has no issues.

The navigation system always directs me to take every exit off a freeway. Should I delete all my "marks" in the system or is there something more I can do?

My master warnIng lIght came on In my car.I took my car into Hooman Toyota in Long Beach, California. They did a diagnostic test and performed their MPI WORLD CLASS INSPECTION. While I was getting it tested they said the invert water pump was under recall. No biggie. Nothing was found in the diagnostic and the recall was fixed.
Two days later I took my car to Palms Springs. While I was driving out there the master warning light came on. I started to lose power but it seemed like the computer would reset and it would be ok for about 15 minutes. I even lost power in the engine. I finally made it out there and figured it just needed to rest. 6 hours later I took off for home. 10 minutes into it the lights on the dashboard came on. The car lost all power and I was stranded off the freeway. My battery was down to 1 bar. I left it there overnight and had it towed to the nearest Toyota dealer. They said I need a new battery and that theirs bad gas. They wanted to replace the fuel tank. I replaced the battery.
The next day they said that wasn't it and was going to continue searching. I ended up towing it to my mechanic. He said there was no coolant and the headers are blown. He said I was better off getting a new engine. Let me take you back two days when that WORLD CLASS MPI INSPECTION was done. There was an 8 page report specifying what was passed on the inspection. The battery, coolant levels along with other fluids passed. Not to mention hoses and clamps and about 30 other things. I feel something was missed in that WORLD CLASS INSPECTION. I feel they are responsible for the car ending up the way it was.

I was on my way to work this morning when the car just stopped accelerating (or so it felt), all the dash lights came on, I pulled over to the side of the freeway (I was very lucky). Radio and a/c were still working. Powered off, powered on too soon a couple of times - the red triangle and check engine both came on again. Cooled my jets and gave it a few minutes, powered on and the red triangle was gone, but the check engine was still on. Drives perfectly, no problems w/either gas or hybrid engine.

So on my wives Prius which is an 2007 the rear tires are wearing more greatly on the insides that the outsides and they are wearing evenly on both the rear left and rear right inside. So not one is more worn than the other..
The tires are heavily worn, with that said the car rides extremely bumpy to the point the entire car is shaking on the freeway at 75 mph or higher. So much so it induces motion sickness which is odd for me. So also besides the alignment question, what else could be causing the insane amount of bumpiness? I balanced and rotated them yesterday but that didn't solve the issue.

Why I am smelling coolant? I have a 2004 6.0 SD.It generally happens when accelerating up to freeway speeds or passing cars, Medium to hard acceleration and the smell is strong and will go away after a few min. The obvious thing is to check for a leak but I haven’t seen any.

2006 Prius ...
Symptoms: The shudder feels like going over a "washboard" dirt road. It mimics the normal "cough / hesitation" that occasionally happens when the MG2 switches to the ICE while accelerating, or vice versa at a stop light. However, unlike the normal switching, this is continuous. It ONLY happens when accelerating; as soon as I lift my foot from the gas, the shudder quits. Although it is worse in stop-and-go, it is also noticeable on a clear freeway. It is worse with a cold engine, but continues from speeds of 10 mph all the way up to 80 mph (and probably higher.) The shudder is slower at lower speeds, and faster at higher speeds. It is most dramatic when making a left turn from a dead stop - the whole vehicle shakes. Weather conditions vary, but usually it happens on dry, paved roads, anywhere from 30-degrees to 75-degrees (F).
Frequency: first noticed a few months ago, gradually becoming more frequent. Now, it is almost every time the car is started. (Sometimes it accelerates without any problem at all.)
Diagnostics: The "Check Engine" light has been on for about 5 years (dealerships couldn't find anything wrong and it turned out to be the MG1 battery.) But when this new shuddering happens, the "Check Engine" light blinks continuously until the shuddering quits (i.e. let off the gas or brake.) There are no other indicator lights on (no triangle of death). And the diagnostics mode tells me nothing.
Other Info: The MG2 battery has not been replaced in the entire life of the vehicle. The MG1 battery was replaced, however, about 2 years ago. Regular oil changes have been kept up, along with air filter replacements, brake pad replacements, tire rotations, and all the other standard maintenance. It has had one owner, and is at 255,000 miles. MPG is currently at about 44.4 and has not changed since this problem started.

So after doing some troubleshooting and researching in trying to find out on my 87K 2008 Prius Std "Noise in the engine while accelerating", "Approximately 10% reduction in fuel efficiency, due to lack of power from engine" & "Glide seems to be degrading over time", here is what I have observed.
1) When I push the gas when the car is parked the engine does not seem to rev in a stream, it goes up for about 3 seconds then goes down for 1 second, then again goes up and then down and this keeps happening until the gas pedal is kept press. In conventional cars the rev should be streaming continuously and proportionately to the pressure applied on gas pedal. This almost seems like a misfire, but from the drivers seat I do not hear any blasts, I have never tried this before so I don't know if Prius's are suppose to be like this. Also no Alarms on the MFD.
2) After using the 5.25 oz fuel injector cleaner in back to back half tanks I saw the engine regaining power and hence bettering the fuel efficiency. Does that mean I should get a Fuel Injector cleaning done by Toyota?

I have 2008 Prius with 80K and I will try my best to give all the information that I can. The past few days during about 10-15 MPH driving, my car started to shake a little bit when I try to accelerate. It doesn't want to go no more than 5-10 MPH and I feel like I was driving on the small bumps. It went away after 10 seconds. Again, I can't duplicate the issue. It happend only twice.
Could this be related to 12 V battery issue, tires issues, transmission, fuel injection, spark plugs?

My 2006 is having acceleration/power issues. It won't go above 35mph while being very slow accelerating. Toyota diagnosed it as needing a new battery so a new $2K battery (not rebuilt one) was installed. It still has the same problem. It seems like a problem between the electric/gas power transfer.

We have owned our 2008 Prius since new so when it misbehaves we know it.
Starting yesterday, when accelerating from a stop light we would be on electric ONLY. The ICE would not even TRY to start. There were NO fault lights or other indications. Then the ICE would run a bit and stop and sometimes begin to act almost normal. We watched the HV battery charge go from 3/4 to one bar in a matter of minutes.
We limped it back home, the ICE was running so we let it run until the battery got up to three bars and he ICE shut off. Then we got in my 05 Prius and finished the task at hand.

My car has 155k miles and I haven't had any previous issues with it. I noticed probably 30k miles ago the beginning of a whine sound when the car accelerates. The noise has been getting louder (it's really not that loud) but I am wondering what this could be. I want to avoid anything happening to the car and want to find out what the problem is so I can fix it.

I recently bought a 2006 prius used with 100,000 miles and have been hearing a very disconcerning sound coming from underneath the car. It is a screechy noise that is always there, but especially when i accelerate or break going up a hill. I have had it checked out by both a dealership and an independent mechanic neither party has info what it could be, even after hours of troubleshooting, as well as showing then a video in which you can hear this awful sound.
