Jeep - Cherokee :: Shrill Whistle Emits When Release Brake Pedal
I have always taken car to dealership for service/repairs. Recently left car at dealer service for just the above issue. They said they could not duplicate the sound. Perhaps they didn't drive long enough..it hadn't 'warmed up'? Everyone who rides with me hears it. It is very very annoying. What could this be?
View 6 RepliesJeep - Cherokee :: Whistle Sound On Acceleration And Deceleration When Transmission Is In Gear And Moving
My wife and I just bought a pre-owned 08 Jeep Grand Cherokee with about 60,000 miles that just started to make a whistle sound on initial acceleration and deceleration when the engine is warm and the transmission is in gear and moving. The sound does not happen with a cold engine, when the transmission is in park, or neutral. A local mechanic checked it for vacuum leaks and didn't find any. He thought it may be a dirty throttle body, so I cleaned that out really well, but the whistle didn't go away (it did make the jeep run a lot smoother!). It's difficult to pinpoint the noise since it only happens when the vehicle is actually moving.

2015 Jeep Cherokee 2.4 engine. Engine is very noisy at idle. Not noticeable when driving. It has variable valve timing or valve lift. I also has a big black hat on the engine, I wonder if that is supposed to quiet the engine some, if so it isn't working.

I was driving my 90 Jeep Cherokee (automatic transmission) last night on the freeway when I suddenly lost power. The engine continued to idle (but roughly) but pressing the accelerator did not result in any increase in engine speed or vehicle speed. The car came to a stop on the off-ramp but I was able to restart it and limp along at idle speed for another few blocks until it came to a stop.
I suspected I may have run out of gas, despite the fuel indicator showing a quarter of a tank but after adding 2 gallons of gas to the tank it wouldn't start. It sounded like it wanted to but it wouldn't start.
Jeep - Cherokee :: Air Conditioner Does Not Always Blow Cold
I have a 1999 Jeep Cherokee and the air conditioner is giving me some problems. The issue is that at random times, it stops cooling, and just blows hot air. Sometimes I can drive all day, and it's fine. Other times, it only blows cold for a few minutes, before the air gets warm.
I've started checking under the hood when this happens, and the compressor is not engaged. I noticed a couple of times that the hoses were frosted over (not every time when the compressor was out). I have found that when the air starts blowing cold, I can turn on the heater for a few minutes, and then when I turn the A/C back on, it will blow cold air again. However, often times the cold air will only last around 10 minutes before it blows warm again. Plus, there are a couple of instances where the heater trick didn't really work.
Jeep - Cherokee - Transmissions :: 2000 - Won't Go In Park In Cold?
In the really cold weather after I start my Jeep and it goes in Drive and it's driven for several miles when I go to put it back into Park the shifter gets hung up. It will go into all of the other gears except for Park. If I wait a while it goes back in but it can still feel like it's not smooth.
View 2 RepliesJeep - Cherokee :: Rough Idle Intermittently
I have recently cleaned my throttle body and still have a rough idle. The rough idle is intermittent and especially occurs when I am in park and then hold on the brake and switch to reverse or forward without pressing the accelerator down and let it sit for a second. When it happens, it is usually so rough it wants to just stall out if I don't give it some gas.

Jeep - Cherokee :: 1996 - AC System Only Blowing Cold Air Out Of Defroster Vents
My 1996 Jeep Cherokee A/C system pushes cold air but out of the defroster vents not the A/C vents. Why this is happening? I suspect it is the slide switches for the A/C system but I am not sure and do not want to take the dash apart before I have some confirmation. I have checked the vacuum hoses with the heater/A/C system and they seem fine.

1996 Jeep Grand Cherokee 4L
Problem "Stalls at idle and at hwy speed" sometimes starts right up and sometime will not start. Sometimes it will lose acceleration but engine will still be running and you can punch the gas and it will go again.
It has been in the shop for most of the last 2 months. Driven in 3 times and hauled in twice.
Low mileage 70,000 - has been great until now - serviced regularly.
Did get new fuel pump only about 10,000 miles ago do to starting problem but in that case it just did not start.
Independent shop replaced distributor cap, rotor, coil, fuel filter. No codes and couldn't duplicate problem.
Jeep dealer replaced fuel pump (they said wiring problem), O2 sensor, engine module no help, they asked us to pick up car because it ran fine. It stalled within 2 miles of shop.
We replaced gas cap just in case.
Limped back to shop to replace crank sensor as it was suggested several places. Ran fine for about 45 minutes then back to old tricks. Relays have been checked. Still at shop trying to trace problem. At least nobody is saying they can't duplicate problem as it now stalls all the time.
Jeep - Cherokee :: Low / Fluctuating Oil Pressure Gauge And Spiking Temps At Idle
I have a 1998 Jeep Cherokee L6 4.0 Liter automatic with 223,000 miles.
The oil pressure usually runs around 1/8-1/4 when driving around town and now I am getting temperature spikes. I had the coolant and water pump replaced last fall when I was having similar idling issues then. My coolant isn't a perfect green color--it is a little bit grey, but it is full. I cleaned the entire throttle body last January, cleaned the IAC today, and redid the NSS this week (not that this probably matters, just being thorough in my explanation).
It seems to happen worst on hot days (of course) when idling in traffic for a few minutes and makes the air conditioned air run warmer than it should.
Is this a busted radiator? The mechanic said I did not have a leak when I had him check last week.
Jeep - Cherokee :: 2001 - Very Bumpy Initial Idle / Car Shake Back And Forth
I have a 2001 Jeep Cherokee Sport edition, automatic transmission, about 100k miles. Recently, when I turn on the engine -- sometimes -- it is very loud, and the car really shakes back and forth (in place) with the engine. It almost feels like the car is going to die. It feels like a very bad idle. If I wait, nothing changes. If I turn the car off, wait, and turn it back on, nothing changes. If I hit the gas, it continues, but decreases very quickly and by the time I hit a stop sign or red light (let's say 100 yards away), the car is more or less fine; no more fear that it's going to die, although there's still some noise that seems like it's coming from somewhere between the transmission and engine. I had the starter replaced last June (when it went kaput) and replaced the idle control valve a couple of months ago (the car kept dying when I came to a complete stop). I mainly drive it to/from work, about 50 miles each way, going 45-80 mph on a hilly freeway, and there have been no problems while driving.
View 2 RepliesJeep - Cherokee :: 1998 - Intermittent Cold Starting / Carburetor System With Choke Sticking
I have a 98 Grand Cherokee (V-8) with 127K on it, that sometimes during cold starts acts like an old carburetor system with the choke sticking. It floods, chokes, it sputters, and you have to maintain an RPM of about 2000 to keep it running and get it to snap out of it. A local shop did a tune up on it before this problem started to happen intermittently, aside from this, it seems to run well. I took it back to the shop and they did several diagnostic tests and even got it to do it for them while they had it.
I told them that it seemed like if we released the key from the start position as soon as it began to fire, the problem would happen, if we held it I the start for a bit longer we could usually avoid it. They returned it to me saying that "Yup, if you hold the start position longer it won't happen, and by the way here is a bill for $103." With the recent below zero temps, it's getting worse, almost unavoidable. My wife says it uses a lot of fuel when this is happening but we have not actually tracked the mileage. Other than this it's a great car but I'm ready to drive it off a high mountain cliff.
Jeep - Cherokee :: 2000 - High Pitched Whistling Noise In Cool / Cold Weather
My Jeep makes a whistling noise in cool/cold weather (~60 degrees and below) that no mechanic has been able to diagnose let alone fix the problem. Here are the details...
-high pitched whistling (can be heard inside and outside the car - very loud) only when temps are about 60 degrees and below-after 5 minutes of the car running-only when RPMs are about 2.0 or below.
However, RPMs can be higher when it is colder out and it will still make the noise-as you push on the accelerator, the noise gradually decreases until RPMs are high enough to completely stop the noise.
When temps are around 50-60 degrees, sometimes the whistling will stop after the car has been at a complete stop for about 1-2 minutes-If you turn off the car and let it sit for 1-2 minutes, then turn it back on, usually the whistling will be gone. It will need to sit in the off position for longer the colder the temps are. This problem has been ongoing for about 4 years.
Cherokee :: 2002 Jeep GC Engine Stalling At Speed
My wife's 2002 Jeep GC has just started having the problem of stalling at speed. Happens without warning and will start back up with out any signs of trouble. No CEL. Car has a 6 cylinder with 130k miles and is well maintained. Have been reading around this forum and have seen a few people post similar issues. I will look at the connection at the ECU tomorrow. Is this a common area of trouble?

I own a 2001 Jeep Cherokee with 104,000+ miles. It runs great and doesn't have any issues. However, i started it up this morning and the check engine light came on. Should this be concerning? I haven't done any real maintenance on it since it runs so well. And i guess that's my other question - what should i do to the Jeep to keep it running for another 100,000+ miles? Spark plugs? Timing belt??
