Jeep - Grandcherokee :: High Idle Speed And Trying To Shift While At Highway Speeds
2004 Grand Cherokee. I was pulling a heavy trailer 1000 miles, and while coming down a mountain pass 50 miles from the end of the trip the check engine light came on. All other gauges (oil pressure, temperature, etc.) had not changed while climbing or descending and I was in low gear while descending to save the brakes. I drove the rest of the way to the destination without incident. I tried turning the Jeep off and restarting it several times to see if the check engine light would turn off and it stayed on. The next morning the light was off when I restarted it and has not come on again since. I hooked it up to a scan tool and received 2 codes: P0152 and P0132. 2 days later I noticed that it was revving high while idling and in Park. It would rev between 1500 and 2200 RPM while in Park, and at 900 RPM while in Drive. Also, while travelling at freeway speeds it seems like it's trying to downshift for no apparent reason. I hold the throttle still and have even tried cruise control and it intermittently increases engine speed, without changing ground speed. I assumed that I got the transmission too hot while climbing/descending and that the error codes listed above (related to O2 sensors) were associated with that, but now I'm wondering if something more has happened.

I have a V6 Automatic 2001 Jeep Grand Cherokee with 94k miles on it. For the last two years my transmission has been slipping only when I make left turns. I have tried changing fluid and filters. The problem hasn't gotten worse but it is pretty dangerous as I cannot accelerate when I make a left turn. I was wondering if there is anything that could be causing this problem.

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..?

When I fill my tank with gas I get a very strong odor of gas throughout the vehicle, what do I need to check to fix this?
Also this one is weird, but everytime I make left turns ONLY, my Jeep does a down shift but stays in Neutral longer than it should but then kicks into gear by me taking my foot off the gas pedal and reapplying. What this could be? I have made sure that my Transmission levels were fine but I am baffled what the problem is?
Prius (2001-03) :: Humming Noise From Rear At Highway Speeds
I have a 2001 w/94k. New tires and alignment (3k). Recently I have been hearing a humming noise which can start to be heard around 45mph which gets increasingly loud up to 65mph, and then seems to quiet down if I go above 70mph. From the driver's seat it sounds like it's coming from the driver's side rear of the car and from the passenger seat it sounds like it's coming from the passenger side rear of the car. So it definitely sounds like it's coming from the rear of the car. Bringing my car in to get looked at it is difficult with my work schedule, so I thought I would try here first. Around the city there is no noticeable sound and there has been no loss in MPG that I can tell (44-47).

I have a distinct coolant smell inside my Jeep (2009, 60k miles). I popped the hood and couldn't spot any leaks nor was there any fluid underneath the vehicle. I took it into a mechanic and they smelled the same thing and put the coolant system under pressure (as well as doing a visual inspection), and could not find any leaks nor was there any evidence of fluid by the vents. They also noted that my coolant levels were still full and I had not added anything to the car. The current theory is a pinhole leak in the heater core (the smell is definitely worse after the car has been driven a bit).
I have had one suggestion to add Bar's Stop Leak to the radiator, but the mechanic said this was a Bad Idea (his argument being that since there was no visible leak in the system it would likely just gum things up). Since the vehicle seems to be otherwise operating fine, I'm hesitant to replace the heater core, but there's a good chance it's still under warranty, so I could go that route.
So, could it be something other than the heater core? Should I have that replaced or would the Stop Leak be a good idea?
Jeep - Grandcherokee :: 1998 - Slow Drip At The Rear Main Bearing
My mother's 1998 Jeep Grand Cherokee (60 k miles!) has developed an annoying slow drip at the rear main bearing (6 cyl). Are there any additives that are safe and might slow this? She just had the oil changed, so it's not a good time to be talking about high-mileage oil.

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?

Jeep - Grandcherokee :: One Click Noise When Key Turned But No Start
I have a 2005 Jeep Grand Cherokee Laredo V6. I am ready to sell it but I have a problem and the problem only happens when I'm driving it. Every once in awhile..about 7 times a week, when I turn the key it will make a one click noise but not start. It then starts after the 2nd or 3rd try. I have now taken my Jeep to 3 car repair shops. It has never happened with any of them. They have checked the usual suspects: battery, alternator, and starter (I even had a new starter installed just in case) and everything checks out. My latest car repair guy has had it for 3 days and it starts every time. The last time I brought it home 10 minutes after I had cut my car off and got back in to go somewhere, it did it again. There is no consistency when this happens whatsoever.
View 6 RepliesJeep - Grandcherokee :: 2004 2WD - Vibration And Noise When Braking
2004 GC, 6 cyc, 2wd. Had TERRIBLE noise & vibration when braking but problem was intermittent, no codes generated. Everybody suspected ABS problem. New pads, new rotors, new ABS module no luck. Frequency increased but severity decreased. Technician finally experienced one occurrence, identified & replaced a weak steering stabilizer. Problem has surfaced again but not so severe and appears to be increasing in frequency.
My best description is when braking from 45-50 mph, Vibration & noise begins at about 35 mph, increasing in intensity until about 18-20 mph then stops. Seems to me that the transmission downshifts and the noise stops. AMCO suggested a cracked flywheel or loose bolts on the torch converter. Also the engine idles at 1100-1200 rpm on start-up then goes to 850 rpm - will not go lower. Does this sound like a transmission problem? The transmission was rebuilt/replaced at about 94,000 miles and the problem started at about 111,000 miles.
Jeep - Grandcherokee :: 1999 V8 - Top End Noise And Dead Cylinder
It was running on 7 cylinders and had not been tuned in probably 50,000 miles or more. I recently bought it at auction. Changed spark plugs and 1 coil for the dead cylinder. Rear cylinder on passenger side was not firing. Compression test shows 150 psi that cylinder. Fairly loud mechanical pecking from that area which was isolated with a stethoscope. I suspect a flat cam lobe or broken rocker arm.

I recently began hearing a noise from my car when I change the temperature inside the vehicle. When I adjust my temperature control either direction, hotter or colder, I hear a temporary clicking noise that is pretty loud. It sounds like it is coming from behind the dash. It sounds mechanical and stops after a few seconds. I have a manual temperature dial. This is not a digital display or climate control. This is on a 2005 Jeep Grand Cherokee.
View 6 RepliesJeep - Grandcherokee :: 2008 - Slight Delay And Whirring Noise
For the past day and a half, when i start my car there isn't the usual smooth, quiet sound of the engine starting. There's a slight delay, and a whirring noise. When i put the car into gear and accelerate, the noise increases in volume and pitch. I think it might be something with the power steering pump or a belt issue, but I'm not fluent in Car and Driver speak.
View 1 RepliesJeep - Grandcherokee :: Squealing / Screeching Noise When Turning On Air Conditioner
A little over a month ago my battery died and I ended up having to get the battery installed one day and the alternator installed the very next day. After the alternator was installed, I started my car up and when I eventually turned the Air conditioner on, it started making a screeching/squealing type noise. I was first told it was the belt needed some lubrication but that didn't work.
I was later told the ac compressor was bad so I had it replaced. The mechanic thought he ordered a bad compressor so he ordered a new one and installed it....it was quiet for about 2 days but then it started squealing again. the sound was not as bad as before through but it was slowly getting worst. I took it back and he then told me the alternator was causing the problem on the ac compressor so I again I had the alternator replaced....no change. He also replaced the belt and no change. at this point we don't know what's causing it?
Jeep - Grandcherokee :: 1999 - Knocking Noise On Wheel Area?
I have a 1999 Jeep Grand Cherokee that, upon starting in the morning, has a knocking noise coming from the front passenger-side wheel area. It only knocks when the car starts moving, and stops once I get up to 15-20 miles per hour. It ONLY does this when the car is cold. The noise does not occur throughout the day, only when I start it each morning. Is it something to do with the wheel bearing, but that does not seem to be the case.???
View 2 RepliesJeep - Grandcherokee :: Rumbling Noise From Back End When Start To Accelerate
I have a 2007 Jeep Grand Cherokee that I absolutely love, but lately a I've been noticing a problem with it gradually getting worse. When I am on my way to work in the morning, and I get on the on ramp to the highway, as I start to accelerate the back end of the car starts to make a rumbling noise. When I look at my gauges the rpm's are going up and down kind of like it doesn't want to shift. The only other time I notice this is when I try to climb a hill on the road or highway. There is no check engine light on. I have had this problem for quite sometime, but just recently noticed it because it has gotten worse. My husband has had a few mechanics drive it, and has asked a few others about it. They either don't know or have a very wide range of things it could be. My friend I work with had a Pontiac Grand Prix. She said that her catalitic converter plugged up and caused her transmission to go out.
View 2 RepliesJeep - Grandcherokee :: Distinct Clapping Noise When Engine Is Not Up To Operating Temperature
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.

Jeep - Grandcherokee :: Knocking Noise Coming From The Valve Cover Area
My 1999 jeep grand Cherokee with 170000 miles with a straight line 6 cilinder has a knocking noise coming from the valve cover area. It is only present during a cold start and for about 2 to 3 minutes. Once it starts getting hot it stops. The engine runs fine it has lots of power and I do not have any other issues.
View 5 RepliesJeep - Grandcherokee :: Front Differential Noise - Pitch Increased With Velocity?
Recent noticed a whirling noise coming from the front of the car. Pitch increased with velocity, but not RPMs. A mechanic diagnosed it as a worn front differential. I have a long highway trip coming up and want to know if this will stress it to its breaking point and I'll be stranded. Also, what should it cost to repair. This mechanic said an overall is $1K. 267K miles on a 2001 Jeep Grand Cherokee with the 4.8L V8 engine. Never had a work done on the front differential.
