2021 Dodge Durango Problems

What owners report

Owners of the 2021 Durango most often describe exterior lighting failures, especially the driver-side daytime running light inside the sealed LED headlamp assembly, which requires replacing the whole unit. A smaller but steady share of complaints cover electrical and infotainment glitches, coolant leaks and no-start or stall events, air bag warning lights, and the rear spoiler separating from the roof. Many lighting reports come in above 50,000 miles, while electrical and air bag reports cluster in the first few thousand miles.

1. 1
   Exterior lighting

   Driver-side daytime running light / LED headlight failure

   • 75 complaints (37%)
   • median 57,179 mi at 5.2 yrs old (4 state mileage, few)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,300 (median of 23 quotes)
   • filed 2021–2026

   Owners describe the driver-side daytime running light, headlight or turn signal going dark without any warning, sometimes with moisture inside the housing or flickering before it fails. Because the LEDs are sealed into the assembly and the bulbs cannot be replaced separately, dealers and shops quote a full headlamp replacement, and owners say they were told the repair is not covered by warranty. Several also describe water getting into the rear liftgate light bar and causing random flashing or dead segments. Reported from roughly 30,000 to 90,000 miles, often noticed by other drivers or police rather than the owner.

   What to check: Check that both daytime running lights, front turn signals and the rear light bar light evenly, and look for condensation inside the lenses. Ask whether any headlamp assembly has already been replaced and who paid for it.

   “My vehicle is 5 years old with 54,000 miles on its and my driver's side headlight has failed. The headlamps are LED and in order to repair them, the entire housing needs a replacement, not just a bulb. My headlights need to be operational in order to drive safely at night. I have an appointment with the dealership to confirm the issue. There were not any warnings or failure symptoms.”

   NHTSA complaint #11759301, filed 2026-08

   “It’s known that the DRL and race track tail lights go out faster than what they should. Also the tail lights once the lift gate is open on the edges of both sides are very sharp. My DRL on my 21 Durango with only 59k miles just went out. That is way to fast and the price to fix is insane”

   Electrical system

   No-start, stall and loss of power (electrical)

   • 24 complaints (12%)
   • median 38,000 mi at 2.4 yrs old (7 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2021–2026

   Complaints describe the engine cranking without starting, stalling at highway speed with multiple warning lights and loss of power steering or brakes, and a dealer diagnosis of corroded control modules or a frequency module that did not resolve the problem. Others report the shifter sticking in park or the vehicle refusing to move after a loss of power, and some describe smoke or fire from the dash area while parked. Reported from near-new (under 2,000 miles) up to about 84,000 miles, including after the vehicle sat parked for hours.

   Recall 22V284000

   What to check: Ask for the service history on module replacements and software updates, and confirm the EGR valve recall (22V284000) was performed on 3.6L models.

   “The vehicle had been parked and unused for approximately 24 hours. We drove it home after staying elsewhere overnight and arrived home about one hour before the incident. About an hour after parking, I asked my fiancé to retrieve our belongings from inside the vehicle. He immediately noticed smoke filling the interior of the vehicle. I opened the hood to try to determine where the smoke was coming from but did not see any visible fire. As I continued looking for the source of the smoke, the vehicle suddenly caught fire. …”

   NHTSA complaint #11748841, filed 2026-07

   “When attempting to start the engine, there is a continuous crank but engine never starts. I purchased this vehicle brand new with 0 miles. This happens every day. Only way to avoid this is to start it with the remote start.”

   • 1 mention a crash, fire or injury
   • filed 2021–2026

   Owners report the rear roof spoiler coming loose, banging, and in some cases detaching at highway speed and striking the rear glass or landing on the road. Complaints describe dealers ordering a replacement spoiler, with parts unavailable in some cases, and owners noting the vehicle was covered by a spoiler recall. Mostly reported between about 5,000 and 49,000 miles, at highway speeds.

   Air bags

   Air bag warning light and non-deployment in crashes

   • 9 complaints (4%)
   • median 7,700 mi at 2.2 yrs old (5 state mileage, few)
   • 6 mention a crash, fire or injury
   • filed 2021–2026

   Complaints describe the air bag warning light coming on early in ownership and, in several cases, air bags that did not deploy in front-end collisions where occupants were injured. Owners report taking the vehicle in for the warning and being told the system needed service, with some saying the light returned afterward. Mostly reported under 10,000 miles for the warning light; non-deployment reports span several thousand to about 57,000 miles.

   Recall 21V280000

   What to check: Confirm the air bag warning light goes out after the instrument-cluster self-test on start-up, and ask whether the side air bag curtain fastener recall (21V280000) was completed.

   “Your vehicle's air bag warning light recently indicated the air bag system may not be working properly. The air bags in your vehicle might not inflate in a collision, or they could inflate without a collision if you do not get the required service. Have your vehicle checked at your dealership. The sos emergency alert opens up on the screen and states it couldn't connect please have vehicle serviced at dealer. Its distracting and can cause you to have an accident”

   NHTSA complaint #11413898, filed 2021-04, 1,280 miles

   “Your vehicle's air bag warning light recently indicated the air bag system may not be working properly. The air bags in your vehicle might not inflate in a collision, or they could inflate without a collision if you do not get the required service. Have your vehicle checked at your dealership. The sos systems comes on the screen and is very distracting when driving. Then it states it couldn't connect to sos system and contact a dealer. Red light comes on the dash and on the rearview mirror. Almost caused me to wreck.”

Buying note. On a used 2021 Durango, budget for LED lighting repairs since a failed daytime running light means a full headlamp assembly, and verify that the spoiler, air bag fastener and EGR recalls have all been done. A pre-purchase inspection that checks the air bag light, coolant hoses and service history for module or software work is worth the cost.
