2020 Dodge Journey Engine

I am filing this complaint to report a repeated safety-related defect involving the engine thermostat in my 2020 Dodge Journey and to formally request an investigation by the NHTSA Office of Defects Investigation (ODI). The thermostat in this vehicle has failed twice, despite being replaced after the initial failure. The recurrence of the same failure in a critical engine temperature control component indicates a potential design or manufacturing defect, not normal wear or improper maintenance. Each thermostat failure resulted in abnormal engine temperature behavior and warning indicators. Thermostat failure directly compromises the engine cooling system and creates a risk of overheating, sudden engine shutdown, loss of propulsion, and engine damage. These conditions present a clear safety hazard, particularly if failure occurs at highway speeds, in traffic, or during extreme temperatures. A thermostat is a non-consumable, safety-critical component that should not require multiple replacements in a vehicle of this age and mileage. The fact that the failure occurred again after repair suggests that the defect may be systemic and potentially affects other 2020 Dodge Journey vehicles equipped with the same thermostat design or housing. This issue meets NHTSA’s criteria for investigation due to: Repeat failure of the same safety-critical component Risk of loss of power or vehicle disablement Potential for engine overheating and sudden breakdown Evidence suggesting a broader defect pattern I am requesting that NHTSA: Open a defect investigation into thermostat failures in the 2020 Dodge Journey Require corrective action by the manufacturer if a defect trend is identified, including a recall, safety service campaign, or extended warranty This complaint is submitted in the interest of preventing further incidents and protecting vehicle occupants and other roadway users.

The contact owns a 2020 Dodge Journey. The contact stated that while driving at an undisclosed speed, the vehicle hesitated and then lost motive power, with the check engine warning light illuminated after the loss of power. The vehicle was towed to the dealer, where it was not diagnosed; however, the contact was informed that the engine may have failed due to the vehicle having no antifreeze, which caused the engine to overheat. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 57,800.

The contact owns a 2020 Dodge Journey. The contact stated that while driving approximately 70 MPH, the vehicle lost motive power and stalled. The contact stated that the check engine warning light illuminated after the vehicle stalled. The contact pulled over to the side of the road, where the contact attempted to restart the vehicle, but the vehicle failed to restart. The contact raised the hood of the vehicle and observed condensation all over the engine. The vehicle was towed to the contact’s son's residence. The vehicle was then towed to a dealer where it was diagnosed that the engine needed to be replaced due to a faulty radiator hose and cap, which caused the engine to seize. The vehicle was not repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 57,800.

The thermostat and housing failed at 57,000 miles, less than 5 years of owning the vehicle. Not available for inspection as it is being replaced as I'm typing this. The problem was reproduced by the shop who is repairing the thermostat. There were no warnings or messages, the car started overheating severely one day and I brought it to the shop. This all started 3 days ago.

Driving on highway and my car started to lose power. When I pulled over and cut it off it wouldn't come on was making a sound as if it was trying to turn on. The engine light came on and a symbol that looked like a lighting bolt in-between two parentheses came on. I sat for 20 mins after trying numerous of times to turn it on and after calling a tow truck. Eventually it came on and I was able to get home but as I was driving the rmp kept going high and the it was making noises. I got home and looked up the symbol and it said it's the electric throttle. I found it strange for this to be happening when I just purchased it last year and I only had 33120 miles on it. I called the dodge dealership and got the run around and bringing it in to be fixed. Eventually I was able to find another dodge dealership and they kept my vehicle for a week straight. Then they said it was the crankshaft sensor and connector that needed to be replaced I also had them do a oil change as well. Just got my truck back today 10/12/2021. whenever I go over 70 my rmp still goes up and it has a noise as if its having issues picking up speed and have a slight vibration with it. I'm extremely nervous about driving it now. Asked the dealership is this normal and he told me basically all the new vehicles goes thru this because of the plastic parts that is used at manufacturers he also said that it could happen again who knows. That made me really uncomfortable. I don't know what to do and the dodge dealership is not much help.
