On the way to work this morning (and yes, getting gas on the way) Black Betty hit 150k miles.

So that means I've got

1) an oil change

2) differential fluid changes

and

3) transfer case fluid change

coming up for me this weekend. Brakes coming soon.

Purchased in Nov 2023 with 92k and it's been my favorite vehicle I've ever owned. I do my own work and it's been great.

Just wanted to share.

I have a older 2010 jeep grand cherokee that has the gutless 3.7l motor with almost 300k on the odometer so my plan is to get a 2009 to 2010 wk or commander and do a 5.7 swap. I have plans to rebuild the motor (part list on my page). it'll be expensive but i think it'll be fun and worth it but the engine build is roughly 7k and im a broke 22 year old but atleast I can do it myself and only half of my tools burnt up in my house!

I'm thinking about buying a 2021 Jeep Grand Cherokee High Altitude, but I'm torn between the V6 and the V8. Is there really that big of a difference in fuel consumption?

I've been trying to connect to the TCM with my scanner to see some live data but theres no reply.

Does the TCM only communicate through PCM or do I have the option to just connect to the TCM.

Im not finding much online about this.

4 wheel drive

Buy or pass?

Any way to get rid of the fake noise? they go through all the effort to make these SUVs quiet, only to pump in fake BS

I’m looking for floor liners for our Grand Cheroke mostly because the second row is already collecting crumbs in spots i cant reach without dragging the vaccum hose acros the whole garage.

The factory mats are fine in the middle but they stop right before those annoying little gaps around the seat rails. I tried a flat rubber set from another SUV for a week and it was honestly worse because the edges lifted and gave dirt even more places to hide.

anyone who has bought liners for a Grand Cheroke, is coverage around the seat rails the main thing to look for or should I be more concerned about the edges curling after a few months??

Hi all, looking for advice here as I am pretty novice to cars and pretty much zero knowledge on cars.

My mom bought a used 2019 Jeep Grand Cherokee 3.6 V6 Limited X with about 110k miles a month ago. However shortly after buying it we noticed it vibrates and has a rough idle after a couple minutes of just warming and there is this rattle noise coming from the engine. I have took it to 4 mechanics now and at a lost on what to do. The car is showing no computer codes or engine lights. However according to a couple of the mechanics they said the computer codes were erased.  Below is what each mechanic has told us.

Mechanic 1: Performed diagnosis and said he believes it is the camshafts and rocker arms. However not entirely sure and would need a $1,000 to perform compression and cylinder leak down test to pinpoint the exact issues and if it is the camshaft and rockers it would be about $2,000 to fix.

Mechanic 2: Said he is unable to work on the car as the problem is coming from inside the engine and whoever had the car before us messed up the engine and computer system too much.

Mechanic 3: Said it is coming from inside the engine as well and is a valve problem. He wouldn’t work on it as it would require taking the whole engine apart. 

Mechanic 4: Performed compression tests and said cylinder 3 and 5 have low pressure about 84 PSI. The other cylinders are working fine. He said he was able to get  the car to run smoother by cleaning up some stuff. He said the car seems to never have been maintained or well kept. He said there are two options either do a full tune up and replace all the spark plugs, two ignition coils, change the cabin filter and some other stuff for $1,200 and hope it takes care of the vibration but not the engine noise or replace the engine for $6,500. He also showed me that the engine vibrates/move a lot itself while parked. 

Would greatly appreciate any thoughts or advice on this matter. I am not sure if the last mechanics recommendation would even tackle the problem. My gut is to go with the first mechanic but the $1,000 price just for the tests is throwing me off.

Hi, I was wondering if anyone could help me figure out what’s going on with my car. Upon start up it sputters while starting up. I’ve taken it to Autozone and they said bad battery but my boyfriend checked it and I had a loose battery sensor. Okay, bought the sensor $193 and changed it myself. Next day sputtering is happening again. I’ve changed the spark plugs but not the coils.

I bought the car three weeks ago. Previous owner did on time oil changes, brakes and rotors, and some other things on the vehicle report. But like I said spark plugs he did not change which I changed myself. And I just recently change my purge valve, coolant thermostat, and esim(evaporator sensor) this past weekend that had a code which didn’t clear until I unplugged my battery. Can anyone tell me what things I can look into for a fix? Google is throwing me all types of diagnostics.

Instrument Cluster flickers from bright to dim.
From your experience how does it affect you? Did it ever give out. Does your car still operate if failure?

Tell me your experiences.

Also, share other experiences with your Summit or Cherokee in general. Just got this one not so long ago and for a higher trim vehicle means more maintenance issues id love to get ahead of

Thanks so much in advance!

A belly pan flew up off the road, my light took most of the impact. It’s going to be about an $8k claim as it hit my pillar and mirror too. it will be a month before I get into the shop though.

After the impact the impacted side didn’t function at all nearly immediately (the led eyebrow part does) but no brights or headlight.

The other one took no impact but would flicker off every once in a while for a couple of weeks, now I have no brights or headlight on either side.

Any ideas on what the issue could be?

Thanks!!

2014 Grand Cherokee Overland, just wanna see if any one else has similar numbers.

Hi fellow Jeep fans! 😊
I’m looking for a little help, coolant looks pretty dark, so it’s probably time for a change. I’d really appreciate any tips or WIS info you can share; I’ll be super grateful!

I checked the radiator for a drain plug but couldn’t spot one. Is it actually there, or should I just pull the hose instead? Thanks so much!

The Jeep dealer recommends 0W-20, which matches the manual guidance I’ve found.

However, multiple local workshops have recommended 5W-30 or 5W-40 because of the desert climate I live in. I also sometimes leave the car parked in direct sunlight for hours.

Is the “hot climate needs thicker oil” advice actually supported for this specific engine, or is it a common misconception?

Does prolonged parking in the sun make any meaningful difference to the recommended viscosity?

I’m leaning towards following Jeep’s recommendation, but would appreciate any guidance or technical evidence explaining otherwise.
