Accent MC (2006-11) :: 2008 - Losing Power Uphill And On Flat Surface With Loud Noise
Dec 28, 2015
Accent 2008 (155,000 km) .... Walter pump, all belt, timing belt, pulley where changed @ 120,00Km when i bought the car.
**No code showing in dtc no check engine light**
I've been losing power uphill, RPM at 4,000 and and losing speed. I heard a loud sound coming from the front starting at 2,500 rpm and up (like if the exhaust air is struggling to get out), not sure who to explain that accelerating noise
On Flat surface it's slower accelerating up to 3,000 rpm with that loud sound. It's like the more i pressed on the gas pedal, the less acceleration i get.
**Running idle up to 4,000 rpm in park, no loud noise, engine running normal sound with no lack in acceleration in RPM**
2 weeks before I had 2 ignitions coil going bad at same time, i run it about 2 miles before changing them, and the exhaust/catalytic converter came hot and melted the plastic dust cover under the car near the catalytic converter.. Did I premature burn or plug that catalytic converter?
Would it be catalytic converter? Fuel pump? Fuel Filter..
I thought of buying a catalytic converter cleaner and put in fuel tank and up the intake..

I have a 2008 toyora prius with 75423mi on it, was purchased with 70000mi two or three months ago. I have had no problems with this vehicle until recently. Being a prius newbie, I decided to ask here. When sitting parked on a slight slope earlier with the car running, radio running, and phone plugged in for an extended amount of time, I received an error on my display stating smething along the lines of "there is an abnormality with the p transmission mechanism, please part the car on a flat surface and engage the parking break completely" paired with a red triangle on the dash. I immediately moved the car to flat ground and engaged the parking break. The car turns one, shifts fine, and acts just as normal as prior. Is there anything I should be worried about? The car is still under toyota warrenty and is due an oil change now. Any clue what the cause of this was and if it will be reoccuring?

I have a 2006 GMC 1500 4x4 just under 100,000 miles on a GM crate engine, 266,000 on truck, runs great no loss of power, no drop in MPG. sill get 17-18 around town on 87. If I put 90-91 gas in when pulling a load I get 18 all day long. So were is the problem? I am getting spark knock. I have tried diffrent gas, just put in plugs and wires. Old plugs looked good. No Cel on, No codes. It happens when I am flat roads and going up hills. I did get to go away for 1 tank when I switched gas stations,but now all brands of gas do it. This has been going for 3 mo's. One more thing it all started after I made a 800 mile round trip puling a trailer ( just under 5000 lbs on trailer 2 axle enclosed). On that trip as always do I used 90-91 gas.

Since the OJ flash, my fuel mileage has seemed better. On a recent trip from Columbia back to the low country on I26 I was getting 30.6 MPG on the trip accumulated mpg readout. Not too shabby for a 3600 lb car with 280 hp! This was driving with average speed of around 74 mph with AC on and obviously windows up. When I lived up in New England it would never break 26mpg on highway at any speed. I guess it likes the flat roads (they're as flat as a pancake around Charleston, SC).

"There is a problem with the transmission "P" lock mechanism Park your your car on a flat surface and fully apply the parking brake." with the red triangle
I've done a ton of google searches on this issue with no luck finding a resolution.

We were flagged down on the highway by a very nice fellow motorist because we were gushing coolant. It was gushing. My passenger was a guy friend who used to work as an aircraft mechanic and works on his own vehicles, so I deferred to his supposedly greater automotive knowledge when he said I didn't need to call a tow truck. We got to within 100 feet of my mechanic (about 5 miles away) when my poor Jeep conked out after losing power and making an increasingly loud clunking noise for the last 500 or so feet. We pushed it in to the auto repair bay. The engine was smoking and would not start. The mechanic replaced a worn out radiator hose, which had become disconnected from the radiator (due to swelling, I think he said?), and the truck runs. There isn't a discernible difference in the engine performance after driving it around town for the day. My question is this: is the engine likely to be FUBAR and am I just playing a waiting game until it croaks?

The 2002 Nissan Xterra (4WD), automatic transmission, I drive for work is starting to have trouble traveling up hills. Just the other day I was traveling on a freeway up a fairly steep grade for ~6 miles. It wouldn't down shift and the pedal was to the floor while I watched the speed slowly drop. I started noticing earlier this year that it will disengage the cruise control on this same steep grade, though not every time. This used to be my personal vehicle and I have been driving it since 2002, so I know how it drives. A mechanic test drove it today and chalked it up to age (our admin assistant took it to the mechanic, so I didn't get to talk to him). Its got something like 170k miles. That is a lot of miles and it is 10 years old, but I am really wary of any diagnosis based solely on age.

I have a 1986 27ft Class C RV on a E350 chassis, 460 ci with about 140,000 miles on it. I inherited it when my Dad passed. I live in the southwest and I am have trouble with it, it seems to be a fuel supply problem, I think?
It runs fine on level ground, but we tried to go to the white mountains this weekend and could not do it. On an incline the engine would start to starve for power. At times we could only drive at 25 mph! It kind of seemed like it was running out of gas, if I tried to give it more throttle it would just die or fall on its face, if I let off the pedal and gave it gas again, it would run for a bit and then do the same again. We were lucky to get it back home. I replaced the electric fuel pump (on the side of the road) during the trip, but that made no difference.
The engine ran cool the whole time! it has only one 40 gallon tank. I can find any other fuel pump on it. but don't understand all the lines going to and from the gas tank either?
I noticed there are these silver metal tubes that feed off the exhaust manifold up to a cylinder looking thing on both sides of the block. One of the tubes is broken from the ex manifold and the manifold is plugged. Not sure how this got damaged or what this parts function is but was wondering if this could be a problem ..

I've got a 1994 Mercedes C220 which recently has been losing power going uphill. This is a random occurrence but starting to happen more frequently. When going up a hill the car engine starts to "miss" and the engine sounds like its fluttering. It is definitely losing power.When I get to the top of the hill; if I turn the engine off and restart it all goes back to normal and runs properly.what is it??

I have an 07 Prius that's been going great for me. About two weeks ago I get this strange error message about my P Lock mechanism and how I need to be parked on a flat surface with the parking brake fully engaged. The car wouldn't start, just a bunch of warning lights. Finally I replaced the 12v battery at the dealership.

I was driving down the street earlier today, when I heard (and felt) a loud *clunk* from under the car. At first I thought it was a blown tire from the way the car was handling, but then I heard the grinding/screeching sound. No matter what gear I put the car in (even neutral), it makes the grinding noise and won't move. I've narrowed it to to either a transmission issue or a problem with the drive shaft.

I have a 1998 F-150 V8 4.6L. Currently has about 83000 miles. I have had this problem twice now. When I park on an incline with the front up hill the engine will not start. It will crank like it is trying to start, but it sounds like its not getting enough fuel. Both times my tank has been nearly full or 3/4 full. Just put on a new fuel filter and the old one was still clean. ( I could blow through it with ease). I think it is the fuel pump.

Accent 2006. When I start the car and start to drive, the car rock on the driver's side. I think it's the driver's rear. Then the feeling of a flat tire is felt but the tire seems to be ok. Occasionally hear a loud noise like from the exhaust and when I stop at a stop sign or stop lights and release the brake the car does not move till the accelerator is pressed and it rocks again and moves. It has 99000 km on it.

2010 Hyundai Accent GLS (automatic)
Just noticed the last few days that my car has developed a shake when accelerating, but stops after a certain speed. It isn't bad yet, but when I started going up a hill today it was significantly worse. The entire car started shaking, but stop after the car leveled out.
I just put in a new front left and right axle two weeks ago, would that have caused anything ?

The issue that I'm having is that when going up hills, the car like automatically starts slowing down basically losing power seems like. I have to put it in low gear and even so it sounds like its straining to get up the hill. No more than 20mph and then begins to drop lower. When going up drive way I have to make a complete stop and then proceed else it will stall. Also, when at stand still in traffic car shuts off. Sometimes I can feel it vibrate before it shuts off other times it just shuts off. took to western auto and they don't know whats wrong with any of the issues. They just said there is nothing wrong with my idle and to put a gas cleaner in when i full the tank up, that didn't work.

So I bought a used Accent last July (40k miles), and recently after I started to randomly lose my first gear about a month or so from driving it. Whenever I stop at a light the RPM will hover over one, but not go down. I thought at first it was some weird thing with the sensors as it only happened when I was low on gas, however now it does it every time I drive. I notice a lurch forward right before it does this.

I got a 04 jetta gli that is making a loud blow off noise at around 15 psi. Up until then the the boost holds fine but then at around 15 psi it just starts whistling really loud and loses all boost. I recently replaced the DV and venthose by the camshaft, and made sure that it is tight. I also installed a 42DD 3" exhaust recently. The car has about 96k on it with stock vacuum hoses except for the aforementioned adjustments. I'm pretty sure it's not the hose and DV I replaced because I made sure that they were tight to see if that was the problem, and it did not fix it.

So I have a 2000 Hyundai Accent that has been a relatively good car for the 11 years I've owened it. About 2 months ago I got a flat tire, which I didn't notice until a passenger in another car told this while waiting at a stop light. I was so close to home (within a mile) that i decided to trek it slowly back. Made it back and a friend of mine put a donut on and I had the two front tires replaced the next day.
Within a week of having the tire changed I noticed several issues with the car. First, it was starting to make a very loud, almost grinding sound. Looked into whether or not tires had anything to do with it since I just had them changed. I pretty much now think its a wheel bearing. It seems to be coming from the right front passenger side. It gets louder as I speed up and also especially loud during left curves and turns.
But all that is background for my real problem. In addition to the above the transmission started acting up. At first I though it was the engine because the problem was initially just sputtering whenever I would slow the car down to a stop. I changed the spark plugs and wires but that didn't work. Then it started having problems shifting. Even going to 3rd now it can take a while, staying at a higher than normal rpm. And when it finally shifts it knocks hard. Only thing I did was have the transmission oil changed since it was about 40k miles past where Hyundai says it should have been done. That worked only slightly (maybe not at all). On top of that, there's also has an engine smell (like hot burnt oil) inside the car when I drive it for an extended amount of time. This was happening before and after the transmission oil change.
These are the first major issues I've had with this car. The only exception is that I've had a failed oxygen sensor twice but that was cheap to have repaired and both times the check engine light was on. It has not turned on once since this started happening. I've stopped driving the car long distances and especially over hills. I go 5 miles between home and work with it now. I was starting to think about getting another car before this happened but I'm still not ready to do that now.
