2006 Jeep Wrangler Engine Freeze

I need some information on why my 2006 Jeep Wrangler engine would freeze up. It is in great condition and only has 26,000 miles on it. Friday my gas light was on and my Jeep stalled. Although the light had just come on and I did not think that was the issue… I added gas, it was tough to start but did and then all lights were on – engine and check gauge lights. I filled with gas and drove 1 mile home.
I was taking it in to the shop Saturday and 1 mile from my house it shut down. EVERYTHING. The shop is telling me that the engine is frozen and I need a new one. They are perplexed as to why a Jeep in this good of shape with only 26,000 miles is in this condition. Never been off the pavement, garage kept, kept up with all maintenance.
They only other issue I have had was the gas tank which was replaced and… my gear shift started sticking in park last week. I was going to have them check this as well.

I have not found any recalls but did see the concern about the problem with the oil pump drive was for certain (about 16,000) 2005 model Wranglers with the 4.0-liter. The gear could wear out prematurely and cause engine failure. Could this be an issue with my 2006?

Thank you very much from a newbie.

Pull the spark plugs and remove the belt and try to turn it over by hand at the harmonic balancer. If it turns over, probably ECM or PCM or something electrical. If you saw no codes or lights or oil pressure light it would be rare to see this. You didn't accidentally fill it with diesel I'm not trying to offend you, I have seen that do a motor in. Water in gas too, bottom of the tank. Unlikely, but possible.

no way a normal engine would seize unless you running low oil.
can you crank the engine?

Reason I asked if you had any CELs was due to the fact that 04-06 Wranglers have a known issue with oil dive gears (that recall you mentioned was for Wranglers manufactured Jan and Feb of 05 but 04-06's are having the same issue but were not covered in the recall). I have an 05 that did not fall under the recall but my oil drive gear got so bad that it cracked in 1/2 and fell into the oil pan causing a complete loss of oil pressure. I was able to shut it right down but if this had happen to me while driving at speed the engine could easily have seized. The easiest way to check for this is to pull the cam angle sensor located on the side of the engine and there is a rod that goes into the block which the mentioned gear is attached to. But if you do remove it, you have to make sure it is in sync when you put it back in.

This thread should help if it is the case

I, too, would push the dealer to honor a warranty of some kind. This is one of the stanchions upon which Jeep rebuilt it brand.

I lieu of a warranty resolution, pulling the plugs and checking to see if it turns over manually is a good idea. NO engine should fail at 26K.......even a FORD.....

If your check gauges light was on, did you check the oil pressure gauge? Sounds like the Oil Pump Drive Assembly gear failed and you lost oil pressure.

Thank you all for your quick responses. I now have the jeep at the dealer and they have confirmed that the engine is seized and I will need a new one. They told me that it has been diagnosed as 'oil starvation' . I asked what could have caused this? Maybe a faulty oil pump? Now they have requested all of my oil change records ect. Which does fall under the 3,000 miles. Although last change was last year, I only drive this on the weekends. If you have any information on these faulty oil pumps, please send me to that site. There is no warranty and the cost is not small.

Yes, last year but even though I am over the 6 months, I have only put on 2204 miles since last oil change.

Read your owners manual for the recommended service schedules.

R U saying...if you can't prove (i.e. done by the Dealer) the oil was changed every 3,000/6 month = warranty is VOID?!?

Indeed he is. At least no warranty coverage for the engine replacement. What the dealership is looking for is proof that it was mechanical failure or a defect in workmanship and not the owner's fault.

Not that they're necessarily saying he's at fault, but that they can approve the warranty work with DC.

Massive oil pump drive assembly failure thread, with pics, is at this site:

Chrysler is paying to install a new cam (2005/2006 owners should read this) - JeepForum.com

Essentially the oil pump drive fails, resulting in no oil pressure from the pump. The drive it the part that looks like a distributor on the right side of the block. It is also the cam position sensor.

Already posted that in post #5 but the OP may be SOL due to not keeping up with scheduled maintenance.
