Prius (Gen 2) :: Rumbling Sound When Starting Car In The Morning Before AM Commute
Jan 22, 2013
I have an 07 with 81.5K miles. Just a few weeks ago I've noticed a "rumbling" sound when starting the car in the morning before my AM commute. To me it sounds like an exhaust issue. This sound is becoming more frequent and now occurs most of the time while I drive. The volume has not increased, only frequency. The engine sounds ok, and no lights or indicators are showing.
MPG performance is down from 45-50MPG to about 40MPG but I think this may be because it's been extremely cold here lately and maybe the gasoline bladder has shrunk? Anyways, what this could be? If it's an exhaust issue could it require replacing the entire exhaust system because it's a hybrid (one mechanic friend I have said this might be the case)? Could it be something as simple as getting a new muffler?

I have a Prius III 2011. I've had it for 10,000 miles and have had no problems at all. Yesterday, when I started the car, it made a loud rumbling and the engine shook, when it transitioned from the electric motor to the gas engine.
It did that several times when I restarted and then went away. The problem happened on the transition each time. Electric motor came on perfectly and then ten seconds later it was like an earth quake under the hood.
My dad watched the engine and said that it shook really hard. At first he thought it might be a fan belt but then he said it seemed more like water or something may have gotten into the gas tank and it was choking...

I have a 2002 Prius that doesn't start properly, It takes about 3-10 tries, put key in , try and start, pull key out, repeat.
Brake pumps are working, 12 volt battery is 6 months old and has voltage. This behavior is only at after sitting all night, not during the day. Car has about 200k miles on it. No codes.

My 2012 Prius v has a moldy smell to the interior upon starting up every morning, now that it is getting warm in FL again. I had this problem last summer, but it went away, while I was on vacation in SC, and the car was parked outside, not in my garage. Any solution for getting rid of the smell? My dealer does not have a solution.

My car alarm goes off, or at least it tries to, when I open the car in the morning. Then every time I try and start the car, it seems to delay starting. IE. I put key in and it struggles to turn on, and lights dim.

For the last several days, every morning when I stepped on the brake the first time in the morning, there was a "ka-luck" sound. Then throughout the day, the brake had no such sound and behaved normally. Is the "ka-luck" sound normal and why it happens? Winter/Rain?

I'm relatively new with my 2011 Prius. I've been averaging about 53.6 mpg, but I feel as if I can do better. I've set 54 mpg as this "magic number" that I'm aspiring to, but if I ever reach that, the number will probably rise to 55 and so on ... (As an aside, if I just set the cruise control while on the commute I'm about to describe, I get the same mileage as I do when I'm working on hypermiling, so I don't know if it's worth the effort with this route).
My daily commute is around 15 miles. About half of this is a hilly and curvy road. The PSL on that portion is 55 mph, and it is a two-lane (one lane in each direction) road. At least one of the hills are so steep that if I DWL, I'll lose between 15 to 20 mph from the bottom to the top; that's with the HSI "pegged" right before the power section of the line. I can maintain speed, or at least lose less, if I go into the power area. Additionally, there are several curves at the bottom of the hills where I must brake down to around 40 mph to safely negotiate the curve.
Finally, it is well-trafficked road as well, so, while observing the speed limit, I may have 10 cars piled up behind me, which makes me nervous.

Wife complained about the noise coming from the front. She said it sounds like an engine noise. I took her car for a few days noticed the noise starting at about 25mph+ (near the driver side). Tried to put the engine in N and rev it, while driving, pretty such it is not the engine.
I do notice the noise is getting a bit louder today compared to last week...Did some google search and "it might" be the bearing. Just wonder what to do next. My wife doesn't want to drive it at this time....so she took my truck today

When I first bought the car I was resetting the trip/mpg every day and getting a daily reading. Then I started to realize that wasn't accurate as a per tank reading. So now I judge my weekly trip/mpg. Currently I am getting 57-59 mpg on the MFD(I do not have a scangauge yet) - so i guess that would equal 54-57 actual.
My commute is 43 miles one way. half of it is mixed city driving a mile of low speed out of my neighborhood to a 55 mph with two 2 mile 35 mph zones and then the second half is interstate.
I have been working on keeping the SOC high for the 55 mph so that i can most of the time slip in and out of high speed "stealth" mode. Usually with the MFD around 69-75? and not drop speed too quickly. maybe a mph per 2 miles depending on the grade.
I try the pulse and glide in the 35 mph zones. coast in, then glide as far as I can and pulse back up. I have been playing with a couple ways,
OPTION 1: use in electric only-takes longer and kills SOC.
OPTION 2: Pulse hard into el+ICE and its crap mpg for a small amount of time. Pulse gently into ICE and decent mpg for a little longer amount of time.

My GA has been sluggishly starting for the last 3 days, usually the first start of the morning then fine the rest of the day. Today is the first day that it has done it during the day. I stopped at Advance Auto on way home and they ran a test on it. I'm attaching the results of it to get your feedback on the possibilities. The battery was replaced in March 2010, the alternator in November 2010.

I have a 2003 Toyota Corolla with 90000 miles, that gets regular maintenance.
I've tried taking it to the dealership, but all they want to do is blindly follow their flowchart, making me spend lots of money in the process. Per their instruction, I've already replaced the battery, I've done a tune up, including spark plug replacement.
I think it's probably some sensor that is busted. The car has 90000 miles now (I bought it 3 years ago with 59000), and it didn't have this problem before. In the past, it wouldn't rev high. But now, the revs wont go back to normal unless you spend a good 10-15 minutes in park until it "warms up", even though this also occurs in the summer.
Generally though the car has run great. It just revs high when starting up in the morning.

Our 1997 Lumina with a 3.1 liter engine and about 190,000KMS is having difficulty starting in the morning.
I have changed the spark plugs, plug wires, checked the connections to the battery and put dielectric grease on them. None of that seemed to make much of a difference. The key has to be held for about 5-7 seconds and it coughs to life and then runs rough for about another 5 seconds and the interior lights are dim during this too. After that it comes to life and runs great.
Is it possible for starters to start to weaken? I have never had a starter do that, they have either worked or not. Besides that, I don't know what else could be the problem.
I have heard that these engines can have condensation issues when the temperature straddles the freezing mark, which it has been the last few weeks. Maybe it just needs to get below zero and stay there?

It seems like the first thing in the morning when I pull out of the driveway my car acts like it not accelerating smoothly. It's kinda jerky and seems like it takes a second to get the gas. I mean I know some cars are a little jerky after not being driven for a day or so but she is brand new, only a few months old.

Sounds like a squirrel knocking on the rear hatch for a few seconds. Is this the fuel pump by any chance??
What i have noticed is that the relay clicking in the CECM is no longer clicking, yet now i hear this knocking in the rear hatch area when i start it up after it sits overnight.

I have a Hyundai-Accent 1.5 GL, Auto, year 2000 car. I bought this 4 months ago and ever since it has been giving the check engine signal. However, running conditions of the car has been normal and therefore, I didn't worry about the check engine signal. Now, the engine is rough idling for few seconds when I start the car in the morning, and then it comes back to normal.

We are going through probably the overall coldest winter I have ever been through. I was wondering is it not out of the question for the cold to impact the power steering on a car. I have a 2002 Kia Sedona mini van and have noticed when starting out in the morning my steering is a bit more sluggish/stiffer and then has the day wears on it is back to it's normal self. It has depending on the temps out said taken a few minutes up to a half hour or so. I have never had this issue before, but again have never had to deal with so many sub zero nights and days in winter....

So for the last week my Civic has been making a low, rumbling sound (almost like an overly powerful bass system) and vibrating whenever the car is idling. The noise is most pronounced when the car is started but continues when I am driving, but only when I take my foot off of the gas. Whenever I accelerate, the noise stops. Also, the noise is very faint from outside of the car, but very pronounced from inside. What could be causing this?

Every morning when I start my LX570 it starts with the idle higher that normal and then after 1 or two minutes is settles.
Along with the higher idle there is a little extra noise from the engine, after 2 minutes the noise goes away and all normal.
Is this the way they start in the morning?
