Prius (2004-09) :: 2007 - Unusual Rear Tire Inside Wear / Car Is Shaking On Freeway At 75 Mph

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.

Prius (Gen 2) :: Unusual Noise When Put On Emergency Brake

My 2007 Prius has started making an unusual sound. At first I thought it was some kind of pump or something, but now???

When I put on the emergency brake, the brake pedal or when I put the car in park or take it out of park and put it in D, it makes a "chuck chuck chuck" sound, not high pitched, but not a low sound either. It seems to be coming from under the hood on the left side. It sounds something like a belt slipping or a pump with a squeak maybe?

It does not appear to make this noise when simply depressing the brake while driving, so I'm not sure it's the same abs actuator issue.

Prius (2004-09) :: Some Unusual Wear On The Inner And Outer Tire

I decided to get an alignment (for the first time since I took delivery of the car). I noticed some unusual wear on the inner and outer tire. I will post a before and after pic of the alignment. As you can see they were unable to correct everything.

The shop says that the prius does not have any way to correct camber in the front nor was there any way to correct the toe in the rear.

I cannot think of anything that would have messed up the rear left. The shop was saying these repairs will need either a new control arm or strut.

Prius (2010-12) :: Unusual Acceleration When Engine Is Warming Up

Basically, when driving shortly after turning on the car (when the engine is still warming up) I often experience a 'shot' of acceleration despite not further depressing the accelerator. In other words, I'll be driving along smoothly and suddenly the car will speed up slightly by itself without me having done anything. This only occurs when the HSI is past the middle (i.e. when the engine is powering the car) and when the car has recently been switched on. It's almost as if the sensor that detects my acceleration is re-calibrating itself while I'm driving, increasing the input to the engine.

The first time it happened it was a bit of a shock and I was a little scared, however I'm used to it by now and can anticipate it happening (however it doesn't happen 100% of the time). It's nothing too serious - it probably only accelerates a couple of KMs above what I'm actually doing but still is a bit of a worry. I'll be taking it in for a service shortly and seeing what they say about.

Prius (2004-09) :: 2005 - Unusual Tire Wear

I have a 2005 Prius with 128,000 miles. At the last service the mechanic pointed out that the front tires were wearing significantly on the outside. I had them do an alignment but the before numbers were hardly out of spec. Everything was in spec except the front right camber - it was right at the limit (negative). Everything else was perfect. I would have expected only significant positive camber on both sides would cause both front tires to wear on the outside, when everything else was in spec?

Prius (Gen 2) :: Unusual Grinding Noise When Accelerating From Dead Stop

I'm experiencing an unusual grinding noise when accelerating from a dead stop but only in this specific situation.

1. When battery is at a low state of charge and the AC is on, therefore, whenever I slightly step on the gas the engine will immediately start.
2. Only under this condition, when I slightly press on the gas and the engine will start to charge the battery and propel the car at the same, there is a slight grinding noise coming from the front of the car. I don't know what this noise is, it sounds like gears grinding, it's very light though.

I know it's not the brake accumulator noise, because that's a whole different sound, and also this only happens under the condition I described above. When battery is low and ac is on, and the engine will need to start right away even when gas peddle is slightly depressed.

The best way to describe the sound is if you were to take a soda can and cut it in half and rub the two halves together (the edges) it sounds like that.

Also, there are no lights on the dash. It's a 2009 with about 73,400 miles.

The transaxle oil has already been changed maybe 10,000 miles ago.

The noise started recently, at least I only noticed it recently since it's summer and I have the ac on much more. There are no drivability issues, but the thing is, this noise was not there before, I know I'm not hearing things. You know when you drove a car for quite some time you will naturally know what sounds are normal and what sounds are new.

Prius (2004-09) :: 2007 - Unusual Noise When In Stealth Mode?

I have a 2007 Prius with about 77,000 km on it. Lately I've noticed that the car would make an unusual noise sometimes when driving at around 50 - 60 km/hr in stealth mode, with slight accelerator pressure such that the energy monitor shows power flowing from the battery to the motor (ie - not gliding or regen braking).

Golf IV / Jetta IV :: 1999 VR6 Shaking Quite A Bit On Startup And When Turned Off

So my VR6 shakes quite a bit on startup and when I turn it off. I figured it was the dogbone mount. I did the clutch trick, jacked up the front end and engaged the transmission. Of course the engine shook a lot, in a forward to back motion, signalling the dogbone was bad. Shifts into and out of 1st and 2nd were pretty rough and i could feel it in both the driver and passenger seats during idle.

Well I just installed the ECS dogbone and while I can't really feel it much in the seats anymore, it still shakes quite a bit once the transmission is engaged. Low end shifts really haven't gotten much better either.

So I am thinking its either one of the other mounts, or the polyurethane bushing needs to be worked in. I am leading toward the former.

Golf IV / Jetta IV :: 2003 Car Shaking And Had A Ticking Sound At Startup

So I was on my to get some food and when started my car it was shaking really bad and had a ticking sound. I popped the hood and the engine was shaking violently, it drove fine one day to walmart and the next day started doing this. I am thinking it could be the coil pack because it was raining when I went to start it.

Passat (B5) :: V6 Shaking A Lot And Making Small Rumbling Noise On Startup

I own a b5.5 2.8l 30v v6. Today I went to get in the car and on start up for the first time in 3 days it started shaking a lot and making a small rumbling noise, sort of like a cylinder misfire. This isn't the first time its happened. I tried searching this up and everything seems to point toward the fuel injectors. In this past 6 months my average mpg has dropped from about 20 to 16.

I am guessing it is this, but someone also said it might be a cylinder misfire. What exactly is causing this? Also in the 1 year of owning it, it makes sort of a diesel sounding noise in the engine. Some people have told me it might just be the valves that need to be adjusted but I have no clue.

This morning I noticed when I started the truck had a rough idle shaking truck. The truck felt weak. Boost would go up but truck felt like it was in sand. While coasting on the highway at 50-55mph the truck not only lags in power but vibrates viciously until the overdrive kicks in that vibrations in cab and ssteering wheel go away.. What might be going on?

Golf IV R32 :: Unusual Noise After 10 Minutes Of Driving

Ok so this past weekend I finally got my car up and running with kinetics stage 3 kit took it out for a drive plenty of times this weekend everything turned out great. Car pulls really hard. I also installed some new coilovers and spacers. This morning I woke up and drove my car to my local general tire shop to get aligned. When driving It first sounded great but after about 10 min, And yes I punched it a few times, the car started to make a wahh wahh wahh wahh wahh wahh wahh wahh wahh. With the speed of the car. Not from the engine! Now I'm hoping it's a wheel bearing or something because I've never heard one before.

Malibu - Chevrolet :: 2002 3.1L Automatic Unusual Cooling

I have a 2002 Chevy Malibu 3.1L Automatic that I've replaced the head gasket, intake manifold gasket, and exhaust manifold gaskets on three times in 6 years. The most recent time I think was caused by an overheating problem originally. A few weeks ago it overheated one time and boiled the coolant, but I did not let it redline on the temp-gauge. Still, the next day I found distinct evidence of coolant in the oil. After replacing the full gasket set and thermostat for good measure, I'm still getting an overheating problem. My assumption was that the coolant leaked into the oil and then when the car overheated I put only water in it temporarily which boiled somehow and probably caused more damage. This happened the first time I had a gasket problem years ago.

I'm not actually losing antifreeze that I can tell, so I know it's not the common intake manifold problem. I've checked all the hoses to make sure they're all properly secure as well and I can identify no dampness or evidence of pooling. I generally run the heat to identify if my cooling system is working correctly or is at least somewhat functioning. It never does upon start-up, but I've found that if I rev the engine to above 4,000rpms for a sustained period of time (5-10 seconds) I can achieve what seems to be flow and the heater will kick on. The temp gauge will also level out and seem to run properly. This works about 95% of the time, but I've only tested it on short drives to work and back (maybe 15 - 20 miles).

I've primed the hoses and also flushed any air from the system on multiple occasions, so I've tried to cover all my basis. One thing that I have noticed is that after revving it and getting it to function so I can at least get to my destination, the heater will run VERY hot. Like it will burn your hand if you hold it in front of the vent for more than a minute or two. Unfortunately, when it overheated the first time I just immediately replaced the gaskets because this was the solution the past two times, which held for about 2 years each, so I don't know if this new, weird, problem is my doing or is something that caused the original problem.

Saab - 900 :: 1993 - Unusual Vibration When Stopped In Gear

I have problem that I've noticed since I bought my Saab 900 equipped with the automatic transmission and am finally deciding to try to address it. Just to clarify, I've cleaned the filter, changed the fluid multiple times to freshen the ATF in the torque converter and it shifts really nicely, actually. The motor is smooth as silk, too. Here's my problem: with the shifter in "D" at a stop sign or cross walk, and my foot on the brake pedal, the car vibrates strongly. In fact, it's even popped my hood open on a couple occasions. However, if it's idling in "P" there's no vibrations that are out of the ordinary and it holds nicely to 900 RPM either way (I have recently cleaned the IAC valve).

Suspecting my brakes weren't grabbing well, I recently replaced the accumulator on my ABS system and had the fluid flushed and refilled at a trusted independent import shop. It brakes great, so I don't suspect it's the brakes. Since the transmission, motor and brakes are great, I can only suspect the motor or transmission mounts, but that doesn't explain to me why the problem would occur at specific times only.

IS F (2008-2014) :: Unusual Noise Coming From Engine Bay Which Comes And Go

So earlier today i noticed this unusual noise coming from the engine bay. You cannot hear it if your sitting inside the car. Only time you can hear it is if the car is running and you happen to be standing in front of the car.

The noise isn't constant and tends to come and go. After about 6 plus tries trying to film it, I finally got a clip where you can hear it for a bit.
