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.

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.

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. …

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. …
