2015 Dodge Challenger engine problems

The vehicle's engine has suffered a catastrophic internal failure at approximately 56,000 miles. The engine is the 6.4-liter HEMI V8. The issue began with a loud ticking noise from the engine. I brought the vehicle to Stoneridge Chrysler Jeep Dodge of Pleasanton for diagnosis. At that visit, the dealership lubricated an unspecified component and instructed me to continue driving. The ticking noise temporarily subsided. Shortly after, the check engine light illuminated. I returned the vehicle to the same dealership, where the technician retrieved diagnostic trouble code P0303 (cylinder 3 misfire). Upon further inspection, the technician found scoring on the cylinder 3 wall, a persistent loud ticking noise from the engine, and metal contamination in the engine oil sample. The dealership diagnosed the failure as requiring a complete engine long block replacement at a quoted cost exceeding $23,000. The powertrain warranty has expired based on the 3-year time limit; however, the vehicle has fewer than 56,000 miles, which is well below the warranty's mileage threshold and exceptionally low for a vehicle of this age. The vehicle has been properly maintained throughout ownership with regular oil changes and scheduled service intervals. No aftermarket modifications have been made; the engine and all related components remain factory stock. I contacted Stellantis customer care to request assistance. They stated that because the vehicle is no longer under warranty, there is nothing they can do, and that the dealership should have submitted a goodwill assistance request on my behalf. The dealership said they would look into it. A complete engine failure at this mileage on an engine marketed as a high-performance powerplant suggests a manufacturing or material defect rather than normal wear and tear.

My SHIFTER is messing up again recall U4 i believe and my its a recall on my vehicle ive had this vehicle for 2 years they stated the previous owner already had repaired but im imforming them i am still having the issue my car will literally stop going in the middle of the highway. Ive almost been close to getting in a accident and all everyone can say is it has already been repaired but i want them to understand that it may was repaired but it wasnt done correctly because something is wrong with my shifter/trasmission and electrical system. Which are both two valid recalls that i have. My shifter just blinks out of nowhere and just will stop at any moment. If the person behind me wasnt paying attention i couldve died or been harm seriously due to this keep happening while i am driving on the highway.

One day after driving home from work there was a message that says low battery voltage on the instrument panel, then it went away. No other warning lights or problems. Ten more miles down the road the message says battery saver mode, reduced functions and then the car started to smoke, I am freaked out at this point praying to make it home safely. I arrive home and pull into driveway and then turn engine off and let it cool. Lift the hood and coolant has sprayed and spewed all over the engine compartment and is significantly reduced. Now parked, engine off the shift lights are still on and navigation panel and radio won't turn off. I had to unplug the battery completely and manually lock the car. The next day I replace the battery, check coolant, and allow car to warm up. No warning lights or messages. Then I start to drive and less than ten min, battery saver mode again, reduced function and power then engine smoking again, coolant spraying under hood and I have no idea what's wrong. Could it be the alternator, everything is still factory parts. Never happened when I changed the battery in 2022. This is scary.

At less than 70k miles, with full periodic servicing done by Dodge dealer (Moss Bros, San Bernardino, CA) all 12 engine rocker arm mounts failed and had to be replaced at a cost of $1,600. This is a common problem in a 3.6L Pentastar V-6 engine, per internet owner reports on Dodge internet groups. Not caused by normal wear and tear, shouldn't be happening at 60-70k miles.

I purchased a 2015 challenger, upon driving the vehicle home noticed the axles making a noise. A week later the noise becomes worse I alert the dealership and bring the car in. They tell me that it's covered under warranty and they promise that when I finalize financing the will fix it. Upon finalizing financing the car fails inspection and the warranty is removed due to the preexisting issues with the car. Thus resulting repair cost coming out my pocket for a car I hadn't had a week. Next I run into a issue the with engine. I take it to get a diagnostic and the technician shows me the history of the car stating that it had a replacement engine installed in the past. The dealer never mentioned the repairs to me before finalizing the deal once so ever. Now I brought it to their attention and they're telling me that I can trade it in but there's nothing they can do. The dealership is rick hendricks chevrolet in duluth georgia, 3277 satellite blvd. The dealership goes up and beyond to avoid me, even while the car was in their possession for repairs for weeks. They never fixed anything in the car. I have video proof of them messing up the car and just leaving it for me to deal with. I also have voice recorded conversations with sales associate managers at the dealership who lied to me and my father in our faces about certain information regarding the deal.

2 issues here. Recalls are for ub4 evaporative emissions canister and v86 catalytic converter. Been trying to schedule this for 8 months. Fca and dodge have a supply issue. Cannot get parts. Imo this is a massive failure. How are we supposed to comply if the company cannot issue parts? It is beyond ridiculous.

The windows in my 2015 challenger is going up and down by themselves, gets stuck, and then won't go back up. Also the engine coils in my car burnt out and was leaking oil all through my car. When I got it fixed, the old coils were from the manufacture and had a broken seal. Was told that my car should've caught on fire with the amount of oil that was leaking.

Driving home in rain and got off highway service ramp. As soon as I turned right the car died. It said my key fob battery was low and would not restart. My son brought up my other key fob and it still would not start. No warning whatsoever came on stating anything was wrong. Could not get car in neutral even after releasing the shift inner lock. It had to be towed to my house.
