As I'm finding out, this is the infamous ticking noise with Check Engine light codes of: P0300 and P0303. These are misfire codes and I have eliminated the sparkplugs, Coil and fuel injectors. Engine idles rough now and don't want to blow the engine so I just have it parked until I can find a resolution. I'm hoping that this lawsuit will help others like me in this situation. The engine is only 114k miles and was running really smooth before this happened. Please keep me informed as the cost to repair or replace the engine is extremely high and I'm retired now and can't afford to pay the cost.

Thanks

This was my first and last Jeep. I have had a few other issues like random codes popping up and that the dealer cleared and couldn't find anything. Anytime going over 70 it sounded like rats fighting and running around in dashboard. The engine made a few noises I was on the highway and had loss of acceleration. Light popped on and off, then stayed on and engine misfire 6 popped up. It's at the mechanic - he said I am gonna need a new engine. I have to see him tomorrow 119k miles 5 years old right after warranty, how perfect could that be. I'm gonna call tomorrow and raise hell.

Had my 2013 GC overland w/ the 5.7L Hemi since the end of 2020 never had any problems with it up until a few months ago. Beginning of May I was on my way into town & heard an unfamiliar chime come from my trucks speakers & checked my gauges & noticed my oil pressure gauge was maxed out @ 96psi gauge only goes to 100.

Since the 1st incident when my oil pressure sensor went out in may 2022, fixed it changed oil & it got the best gas mileage it's ever gotten since I've had it. Then a week later, on my way home @ 3am on a back road, the check engine light comes back in and took it to a shop. They wouldn't mess with it but said it was coming up shift solenoid A, took it to a transmission shop & cost me 1000$ I didn't have.

2013 Jeep Grand Cherokee 4X4 with a 5.7 V8 HEMI. Driving on the hight way pulling our small camper and there was a noise from the engine and then a ticking noice from the drivers side. The Check engine light came on and I lost a ton of power. I had my code reader and it was throwing P303 which is a misfire on cylinder 3. Pulled over and shut the car off.

I was able to drive slowly for a few miles into town where there was a dealership. They inspected the car and informed me that the lifter on 3 stuck and the would most likely need to replace that lifter and the cam shaft. Quote was $5,200. I had he car towed to my mechanic, 120 miles away at an expense of $200 which I was happy with, but still.. Mechanic told me the same thing after inspecting it. I had the repair made and traded it the Jeep in the same day for a GMC Sierra 1500 Duramax 3.0. I read several places where this was an engineering problem from Chrysler where the lifters were not getting enough oil. See this video.

My lifters looked exactly the same. I am so disappointed with Jeep/Chrysler for this. I maintained this engine very well. Never went over on miles between oil changes, followed all recommended maintenance and can only get 120,000 miles out of the car? I will never, ever buy a Chrysler product again and I will do everything in my power to let everyone I know not to as well.
