Jeep - Grandcherokee :: 2006 - Loud Engine At 65 - 70 Mph / No Torque
May 17, 2012
I have an issue with my 2006 Jeep Grand Cherokee v8 Laredo that has been bothering me for a little over a year now. When the temperature gets warm out (over 80) and I am traveling on the interstate up a long hill (65-70 mph, towards the end of my commute so about 30 miles in or about 30 minutes) my engine randomly begins to sound like I am in the wrong gear (RPMs do not change but engine sounds like I just changed to second) and I loose quite a bit of torque. I can maintain my speed but my engine sound horrible. After about 10 minutes of this my engine goes back to normal and I can accelerate without issue. Then randomly it goes back to being loud with low torque. To add to the the fun, if this happens at any time during the day, the next day when I start my Jeep the issue resurfaces and I have no torque for about 10 minutes (5 miles) then all is well for the rest of my commute (40 miles downhill). I had a diagnostic scan done and they found nothing wrong and I also just got both of my exhaust manifolds replaces but the issue continues.

Went over a bump on the highway the other day and heard a loud noice as if I was dragging something under the car. I checked but nothing was there. It reminded me of putting a baseball card in your spokes of your bike when you were a kid. It happened twice and the weird thing is that if I put it into reverse and drive about 10ft The problem went away. But something still seems loose and it sounds like it will happen again. I was googling this and it seems like the noise was around where the center differential or drive shaft?

I own a rear-wheel-drive 1999 Jeep Grand Cherokee. I recently had both rear axle seals and bearings replaced. At the same time I had the mechanic check U-joints, shocks, etc. The noise from the failing bearings is gone, but now I have a loud "howl" that gets louder the more I accelerate. If I take my foot off the accelerator, the sound is gone. As soon as I accelerate, the sound returns. It is barely noticeable at speeds less than 35 mph, but the howl gets increasingly louder as the speed increases.
I returned to the mechanic the same day I picked up the Jeep. We went on a road test and I was given a story about gears in the differential and that despite the noise everything was mechanically sound. Even though the sound was not present before the seals and bearings were replaced, the mechanic assured me that nothing is wrong. This howling is giving me a headache!

I have an '08 Grand Cherokee Laredo, 3.7L V6 with 74,000 miles on it. Recently the exhaust/muffler have been getting loud, and during my state inspection the guy said it would probably need a new muffler/pipe in the next few months. That was about a month ago. Since then there has been an on-and-off horrible plastic/chemical smell in the cabin some of the time. My wife drives it about an hour to work each way, and she says sometimes it gets so bad she has to open the windows (in 20 degree temps....) or she gets a headache. She describes it as a "formaldehyde smell" and says it tastes kind of sweet. To me it's more like a burnt plastic/chemical type odor. I checked all underneath but saw no plastic bags or anything else odd. Nothing unusual under the hood. No visible smoke. I have an appointment in two days to have the exhaust fixed. My question is - is there any way this weird smell could be exhaust related? I am hoping so, because otherwise it's a total mystery. It's definitely not an "exhaust" smell as I know it.

I have a 2006 Grand Cherokee and since I bought the car used the rear right brake has squealed despite having the breaks replaced and serviced twice. I have had the car for less than a year. Recently I have noticed a bit of a shake/thud while I'm driving at speeds lower than 45mph. It almost feels like I have a flat tire, despite all of my tires being properly inflated. I do not have to be pressing the brake to feel the shake, however I do feel the vibrations in the brake pedal. What could be the problem and could it be dangerous?

01 Jeep Grand Cherokee. I just changed the water pump and the thermostat on the Jeep but the last two days when I drove it to work, the heater was blowing cold air and the engine was getting hot, almost to the red. What do you think that I should look into about getting the problem fixed>?

I have a Jeep Grand Cherokee 2001 with about 150,000 miles. About every other day my car will shut off while I'm stopped at a light, stop sign, etc. The strange thing is that the radio and lights (stuff controlled by the battery I assume) does not turn off with the engine. It seems the frequency with which this happens has stayed about the same, and I haven't been too worried until yesterday when I went to start my car and it would not start. It just kept revving and seemed like it was very close to starting.
I opened the hood and saw a lot of corrosion on the battery and luckily I had a coke in the car. After pouring some coke and wiping away the corrosion, the car started up. I have had no problems since I did this yesterday. But like I said, my car engine seems to turn off without warning so it could happen next time I drive. If these two problems could be linked, that is the corrosion on the battery could have caused both the car not starting and the engine shutting off when the car is idling. I took to a mechanic about a month ago and they couldn't find anything wrong with it and, of course, it didn't shut off when they drove it.

I have a 2005 Jeep Grand Cherokee with 120,000 miles. The engine light came on and I took it in for service. The catalytic converter was defective and replaced. After service and 30 miles the light came back on. They erased the memory. After 35 miles the light came back on. So far I have returned 4 times and they cannot find the problem.

I own a Jeep Grand Cherokee 2006 V8 4.7 with 133,000 miles. This week I went to a Quick Service Oil Change , after receiving an oil change they informed me I needed a Differential Fluid Change , that I "should have " had one at my last visit and couldn't wait any longer. After receiving the two , I left and not even fifteen minutes later , I attempted to use my breaks approaching the end of the highway.
Instantly the car started making an extremely long banging / thumping sounds along with the a lot of shaking and the car proceed to dead right there. I got it towed home , the company is supposed to send some one to come do a once over. What it could be? As sad as it sounds, I have a feeling they will do a look over and claim they don't know what is wrong or that it isn't there fault in any way.

My Jeep sounds like it is in low gear and engine sounds like its turning 4000rpm but only when cold. This is so noticeable that dogs stare and pedestrians run for cover. Once the engine and drivetrain warm up a little, all is normal. The reality is that the engine is only turning 2500rpm and it is shifting, but the tranny doesn't feel like its grabbing very well. After just a few minutes driving, all is well and there is plenty of power. Fluids are all topped off and fresh.Is it time to warm this baby up and drive it to the nearest car lot?

I've got a 1998 Jeep Grand Cherokee, 6 cyl. engine, ~145k miles. A few weeks ago, I noticed the engine would occasionally run rough at idle, dropping down to a low rpm (~500 rpm, but erratic) for a few seconds before stalling. This usually happens when in park or stopped at a stoplight, but it's occasionally happened at low speed while coasting to a stop (never while accelerating, or while traveling above 20 mph or so). Generally, the car will restart right away, though sometimes I have wait a few seconds to a minute (I was a real popular guy at that intersection).
At first, no codes came up, so I changed the plugs and wires (I was due anyway). That didn't work. (The plugs, while worn, looked normal to me-no residue). I've since had a P0351 code pop up. Before I throw parts at this code (ignition coil, I believe), is there anything else I should be looking into?

My daughter's Jeep check engine light is on. Trying to get the car inspected so cannot be ignored. I think the code wasP0422, indicating it needed a new gas cap. We bought a new gas cap, cleared the code and it went away for a few days but before she could get it inspected, the light came on again. I saw similar problems suggestions were to get a better gas cap (we got one at autozone), or it could be something like a pump problem. We haven't taken to a dealer - it's a 2001

So this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.

I noticed that my Jeep has been making a distinct clapping noise any time the engine is not up to operating temperature. It sounds worst on cold mornings, but becomes quieter as the engine warms up. The noise is RPM dependent, so I'm assuming it has something to do with the engine. The noise is not audible when the engine is idling in park, but quickly shows up as soon as I put the car in gear and add gas. My father and I think that a slightly loose rocker might be the cause of the noise, but we're not sure. A mechanic friend of his told him that our jeep has self adjusting rockers so it can't really be fixed without replacing it. I've never heard of such a thing so I'm having a hard time believing it. The really confusing part is that it only makes noise when the car is in gear and the engine is under stress, making no noise when it's just idling, even when the engine is revved. Since purchasing it 5 years ago, we have been careful to do regular maintenance on our jeep so I'm somewhat surprised by it.

My 99 jeep grand Cherokee 4.7 v8 4x4 will not start after 2 to 3 short trips. it starts up fine in the morning when the engine is cold but driving for a while while and I stop somewhere and shut the engine down for a few minutes it will not restart.. after I wait 10 to 15 min it start up ok.. Next when I'm driving on the highway, after 10-20 mins of driving, the engine stalls for 5-10 secs. and fires back up..I inspected all connections and the starter which were ok but I did find that the starter is soaked with oil dripping from the valve covers.. Could the oil be the problem..? Even causing the stalling out on the highway..?

2004 Jeep Grand Cherokee V8 4.7 L. Clock from right side of engine immediately after starting engine. Seems to be in rhythm with engine and increases in frequency as I rev. Gradually subsides over first 5 minutes and not audible after that. Recent small leak of transmission fluid, but I'm thinking that has nothing to do with this.
