2020 RAM 1500- Shelby Twp., MI
While driving on I 75 steam began coming through our vents while we were 50 miles from home. There was also a very strong smell of coolant, which gave everyone headaches and made them feel nauseous. After taking it to a shop. We found that it was the heater core that had began leaking. after doing some research, I found out that this is a common problem, even with vehicles of low mileage. I understand that mechanical failures happen however with a vehicle that only has 80,000 miles on it. This should not happen. I also believe this is a safety concern due to the fact that it causes the driver to become nauseous and possibly disoriented not to mention if enough coolant leaks, it can cause the vehicle to overheat or catch fire.

Twice in the past two years, the eTorque system had failed will driving on the highest. When the unit fails, you lose all power asks if you're battery is low, you can pose the ability to even steer. The first time, I was on the i87 going north, and barely made it off the road. I was nearly hit by several semi trucks because this was on a blind turn with very little shoulder and I basically had to hide in the woods for safety. Just this past week, less than two years after the replacement, the same issue happened again. This incident was on route 11, which is very busy and I was unable to get my vehicle of the road. An officer came to shield me until the tow truck came, but it was very sketchy. This total cost is over 3000$, and no support from Ram as to why this is happening. This past time the bearings went and there was a lot of smoke coming from the engine area. The smell of burning electronics was choking in the cab; at that point I had to get out of the truck due to the toxic fumes. I did file a complaint with them. With this being such a safety concern, why is there no recall? I can't be the only person having had to deal with this. From what the dealership says, this is happening a lot and there is currently an 8 month wait for the part. Just thought you should be aware of this very serious issue.

The power steering goes out at random times after the steering warning light comes on. This usually happens after the secondary cooling system kicks in. I have had it looked at by one mechanic who thinks it's the rack and pinion portion of the steering, he was unable to find a replacement part. It is a danger when it happens especially on a curve, it will cause the steering to try and go straight which leads to the truck crossing lanes of traffic which could result in an accident. This all began in May of 2026 when the weather started warming up. Did not have this problem the first 6 months of ownership during the cooler weather of winter and spring. This problem happens almost daily especially during the heat of the day.

2020 RAM 1500- Flowery Branch, GA
MGU Failed, 48v code P0DAF had early signs of premature failure. when on the highway, vehicle shut off completely, no power what so ever. Couldn't steer correctly and vehicle was going highway speeds (approximately 70mph) dealer has confirmed the issue being there MGU gone bad, but I have records of water intrusion multiple times on the rear seats, headliner & back glass (XL1) and water intrusion can cause BPCM to go bad along with the MGU to go bad. they first appeared on or around December 2025, most likely way before that but just never noticed it. check engine light came on and showed a code for the BPCM going bad and then I had the CHMSL replaced 3 times under warranty & then the 4th visit they did they urethane warranty superseded the XL1 and even after that fix, there water leak still occurred and dealership wouldn't fix it they stated Stellantis denied the back glass replacement and further repairs because im out of warranty but the warranty expires 8 Years/150,000 miles and my vehicle is only 6 years old and sitting at 118,350 miles. but the entire problem with water intrusion most likely started anywhere from 60-70,000 miles ago. even when I purchased the vehicle at 39,801 miles I noticed the water stains on the headliner but was advised the CHMSL caused that so it was fixed so technically the CHMSL was replaced roughly 4 times along with the original making it a total of 5 CHSML. so my issue is that its highly possible that the water intrusion that was never fixed for thousands of miles and many months leaked into the rear seats near the 48V Battery pack and eventually started shorting and lead to the MGU going bad. so this all could've been avoided if dealership fixed the water leak many many visits ago. along with the MGU could've been replaced under the major emissions comp warranty way. before that ever expired when it showed signs of premature wear like DTC codes popping up at 100,000 miles and even many more visits prior to December.

2020 RAM 1500- Midwest City, OK
The tail lights keep going out on both sides. The tail light harness does not fit the female adapter properly. You have to hold it pushed in to get the light to come on but when you let go it turns back off. I have already replaced the sockets with Mopar OEM parts and am still having the problem. After researching I found that this is a common issue with this vehicle. It is a safety concern because without tail lights keep other drivers may not be able to see my vehicle at night or when I am braking.
