What owners say about the engine
Verbatim from NHTSA complaints, newest first
“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…”
“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.”
“The contact owns a 2015 Dodge Challenger. The contact stated while driving at an undisclosed speed, the contact heard an abnormal ticking sound coming from the engine compartment. The check engine warning light was illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 120,000.”
“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…”
