2024 Dodge Durango, purchased brand new. AC completely stopped working at 340 miles after buying. Vehicle has had 7+ dealership visits since purchase. Vehicle has been out of service for 40+days total. Currently, vehicle has been at dealer since June 24, 2026 and is still not returned as of July 9, 2026 — 16 days ongoing with no resolution. I request the federal safety agency look into this. Electrical/HVAC: Constant leaking and repeated failures since 340 miles. AC intermittently will not blow air at all, especially when first starting vehicle. System makes loud hissing/whistling sound from dash. Dealer has replaced the A/C condenser, discharge line, compressor, and evaporator core. On one visit, dealer found AC dye present at the HVAC box drain tube indicating evaporator core was leaking. On another visit, dealer noted system was slightly low and stated "not sure if vehicle was charged properly when the condenser was replaced." System still leaks and fails. AC failure in Tennessee summer heat creates risk of heat exhaustion and prevents defroster use. Issue still not repaired. Power Train: Transmission was misfiring and vehicle jolts forward when shifting into drive. Dealer performed transmission reprogramming. Dealer initially claimed they were unable to duplicate the concern and that it "operates as designed." Concern not resolved. Engine: Had to have all spark plugs replaced at approximately 9,000 miles due to misfire issues. Fuel/Propulsion System: Gas/fuel smell reported. Dealer noted system was slightly low. Body/Interior: During repeated dashboard removals for AC repairs, dealer did not properly reassemble vehicle. A screw was left out, causing dash to rattle. Dealer also removed carpet and improperly reinstalled, causing damage. All defects occurred under 10,000 miles. Dealer has performed multiple major component replacements on the AC system. Issue still persists. Vehicle has severe diminished value due to 9+ repair attempts and 40+days out of service. Legal case .

The contact owns a 2012 Dodge Durango. The contact stated that when the vehicle was started, the check engine warning light illuminated. Approximately three weeks later, while stopped at a light, the vehicle accelerated unintendedly. The gear shifter was shifted to park(P) to stop the vehicle. The vehicle was then taken to an independent mechanic, where it was diagnosed and it was determined that the timing chain was blown. The vehicle was repaired, but the failure persisted. The vehicle was subsequently taken to an independent mechanic on several occasions, where it was diagnosed and determined that there were failures with Oxygen sensors, head gaskets, oil pan, oil pump, B2S1 heater, that the intake manifold was cracked, there was cylinder #2 misfire, and the circuit harness needed to be repaired, and DTC: P0300 was retrieved. The vehicle was repaired each time, but the failure persisted. The manufacturer was notified of the failure. The failure mileage was 190,000.

We have researched and noticed there was an open recall in the past with the PCM. We are now experiencing issues such as rough idling, poor fuel economy, stalling and poor acceleration.

Over time, the valvetrain in my engine became gradually louder. Because there were no check engine lights or fault codes, I initially assumed this was a normal characteristic of the engine. That changed on January 2, 2026, when I began to hear a pronounced knocking/loud tapping noise accompanied by a cylinder 8 misfire. At that point, I stopped driving the vehicle and had it towed to a repair shop. Based on the symptoms, we initially believed the issue would be limited to a camshaft and lifter replacement. However, after draining the oil and cutting open the oil filter, a significant amount of metal debris was discovered. Further inspection revealed that one camshaft lobe had been worn down nearly smooth and the corresponding lifter had failed. When the camshaft was removed for full evaluation, all other lobes showed normal, even wear. Only the lobe associated with the failed lifter exhibited catastrophic damage beyond repair. As a result of the metal contamination throughout the engine, a full engine replacement was required rather than a repair of individual components. The basis of my complaint is that this failure appears to be a well-documented and common issue with the 6.4L HEMI engine equipped with MDS. I have since reviewed numerous reports and forum discussions describing nearly identical failures—often beginning with increased valvetrain noise, followed by a single-cylinder misfire and extensive internal damage. This was not the result of neglect or abuse, but rather a known failure mode that ultimately led to the complete loss of the engine.

Under heavy load or high RPM the engine starts shaking badly and the engine loses power and is very unresponsive to throttle. After 30 seconds of light use the problem goes away but comes back immediately upon heavy load or high rpms. There is a technical service bulletin about this, TSB: 09-011-25. The computer indicates a severe misfire on cylinder #1. I first took the Durango to my mechanic since it is out of warranty. The replaced the coil on cylinder #1 and all spark plugs, but the problem continued since the issue is a manufacturer's defect inside the engine. When this occurred the engine light came on the dashboard but nothing prior to the shaking, only after the shaking started.

Last year I notice water in my tail lights. I removed the bolt to help drain the water. Part of my tail lights is now burned out. Now at 77,000+ my start/stop light came on, then the check engine. Scan code was P0304. Misfire on cylinder 4. I changed ignition coil 4, set of spark plugs. It was still misfiring on 4. I had spark plugs on 4 changed. This still did not fix it. The person who changed the spark plugs let me know my lifter/cam was bad. I scheduled with Dodge and they diagnosed it with a blown head gasket. The service rep said the blown head gasket was my fault, however after asking the mechanic said there was no code for over heating or any of that, just the misfire.

While driving on the Thruway, the vehicle tends to misfire which results in lost power to the engine and shaking of the vehicle. The check engine light starts flashing and it becomes unsafe to maintain speeds. The issue was diagnosed as Cylinder 5 Misfire caused by camshaft and lifter failure. This sudden loss of power while driving at highway speeds could cause an accident if it happens during traffic or passing situations. This is a known issue with the 2018 Dodge Durango GT V6 and should be a recall on the vehicle. This is a major engine issue.

My vehicle began to misfire after driving roughly 8 miles, check engine light would flash and ding. After shutting vehicle off for a while and restarting it, problem would be gone until driving approximately 8 miles. Brought to Chrysler service center, where they reproduced the problem and determined it is a camshaft or camshaft related issue. Vehicle is parked at that service center awaiting parts that are backordered until January. Vehicle cannot be driven in this condition. If the camshaft fails catastrophically, it could destroy the entire engine, putting myself and whoever else is in the vehicle in danger.
