2016 Jeep patriot Sport 2.4L refuses to start up

Vehicle broke down in the middle of the road this past Saturday. Can suddenly stopped responding to acceleration pedal. Pulled up the emergency brake, turned car off and attempted to turn it back on. Nothing worked, car refused to start up again. A small amount of what appeared to be water vapor came out of the front engine compartment (could not identify source of vapor) accompanied by a smell that had notes of burnt metal.

- Crankshaft Position Sensor was replaced
- Vehicle had a blown A/C pump which got replaced (found this out upon lifting the car).
- Checked alternator, battery & Ignition Motor (all 3 appear to be operational)
- Attached a Diagnostic tool to car and it claims that it has code P0688
- Checked the power relays, 2 of them had the starting signs of very minor corrosion (as small as a grain of rice or smaller). Replaced both relays.
- Checked all the fuses and all appear to be working.

Car still refuses to start up. We are currently stumped as to what the issue may be can you all kindly advise as to what steps we should take now?

like every other jeep patriot owner - I got the lighting bolt of death and replaced for a 2nd time the electronic throttle body - however the code still remains

I replaced the PCV value last night and will try the MAP sensor this evening. I also spray brake cleaner around the air intake and could not detect any leaks

any suggestions?

Context: Free car. My dad has a 2014 Jeep Patriot Latitude. It's located in a different state, so all I would pay for is the shipping and title transfer which would come out to about $3,000-3,500 total. I would be using the car as my daily driver, averaging about 200mi a week on it. I'm hoping the car would last me long enough that I can save up to get another vehicle. I'm going around in Ubers now, so even with gas, insurance, and typical maintenance I'd be saving about $200/month. It's between this car or no car, since I can't afford a car payment + insurance + gas.

Patriot Essentials:

1. Transmission: CVT (2014)
2. Rust Check: No rust
3. Leak Check: No leaks on the headliner or dome light.
4. Specs: 4WD, 2.4L, 145,000 miles. Cost: <$3,500.

Mechanical issues:

1. CV joint needs to be fixed.
2. Clanking noise when you accelerate in low gear.
3. Rear differential leaks.

Other details

• The throttle wore out on a road trip, and was completely replaced. This happened at 120,000 miles.
• Transmission has never had a problem. He got the transmission drained and refilled at 130,000 miles.
• He is the third owner, and according to the CARFAX no major accidents reported.
• He doesn't use it as a daily driver, car mostly sits around currently.

Questions:

1. My dad is gonna take it in to a mechanic for a quote on the mechanical issues. What dollar amount would make you say "it's not worth the fix"?
2. Say I got all that fixed, do you think it would last me 2-5 years in its condition?
   • At 200mi/week, that's 10,400mi/year, and at 5 years it would be at 197,000mi

Thanks for your help!

I wanna know if it'd be smart to service the transmission and if so what. It's the 2.4L fwd with 4x4 lock 6 speed automatic transmission. The transmission is at 160kmiles and has most likely never been serviced, I got it from a dealership at 140k. Like many it had oil burn issues and I figured that out but I forgot to top it off and it just blew up. Well my new engine has 80k, should I service the transmission and if I goes out ever should I replace. 3.3k engine, parts, labor. I sourced the engine

Hello everybody I have a 2014 Jeep Patriot 2.0L, hoping to find someone who has come across a similar problem to what I’m experiencing. So my main issue is that the lights on my dashboard where the odometer is starts to spaz out and dimming intermittently when the AC is on. It also affects my headlights as well and sometimes the car has a rough idle and will turn off.

I’ve replaced the throttle body , alternator, brand new battery, new ground clamp, did the ignition coils+spark plugs, got a brand new AC system, a new cat converter, and new oil pressure sensor.

At my wits end trying to figure out what it could be ! Any help Is appreciated !

recently the temp gauge goes slightly passed halfway point while driving roads and highways. obd app is showing up to 225F. it will drop some when the fan kicks it but generally runs around 217F to 221F. it drops significantly to 206F when i turn the heat on with high fan. turned back to cool and it will go up. outside temp is 70F.

I tried burping, massaging both hoses which were hot. did this for about 30 min. highest while parked was 208F. i did notice the reservoir gradually fill up but coolant in radiator did not drop. after all that the temp still went up after driving. oil is at safe level but needs to be changed.

thoughts? TIA.

UPDATE: thermostat is stuck closed. end up having mechanic do and flush coolant. joy....

I know it’s still in the “safe” range but my temp ALWAYS stays slightly below the halfway thermometer line.

I’ve changed the relays, ok

had the fans tested and working as they should (seemingly) ok

Changed the main coolant fill hoses. ok

Tested pressure ok

After idle for over 10-20 mins, the temp starts to creep over the line, almost to the 3/4 mark. For my car, this is not normal.

Happens w AC on and off.

what else could it be?
