2021 Ram 1500 Engine Problems

The EGR cooler bypass control broke on my pickup. The dealership stated that this is an ongoing issue with these pickups and that the 2019-2020 pickups had a recall on this. This pickup has 77,000 miles on it. This should not be failing.

The oil pan on my 2021 Ram1500 has premature severe corrosion. When the oil pan fails, oil will drain to the roadway causing hazard to other vehicles and cause catastrophic engine damage disabling the vehicle. I tried to contact Ram about the issue to raise concern about this material failure and they would not take my concern/complaint. A quick search reveals this problem is extremely common. The repair quote is slightly over 1500 to replace the oil pan. Something needs to be done. A recall needs issued and a fix provided for all affected vehicles.

MGU unit failure. Truck is less than 5 years old and just hit 60k miles. Noise came on very abruptly and was lucky enough to get it to a dealer nearby where I was traveling. Still was stranded 4 hours from home and needed a rental to get home. I got a battery warning light and auto start/stop malfunction light and 20 minutes later the truck was dead. I have a family of 5 and need a vehicle for work and to transport kids to school/daycare. Technician said it could take upwards of 8 months to get the replacement part. This is absolutely ludacris for something like this to happen and potentially causing financial damages to people. Dealer offered $10k less than the truck is worth because of the issue so I can’t even get a fair trade in value if I wanted to trade it in. Ridiculous!

Engine malfunction cause low oil pressure and cause a catastrophic failure and lock brakes up multiple people i know have had same issue as me and it due to a manufacturer error on oil gallery bolts backing out and causes rockers not to get proper oil and chews cams up

Exhaust manifold on passenger side has cracked leading to exhaust fumes in cabin, causing dizziness and headaches due to carbon monoxide ram has acknowledged this issue with a TSB but the fact that exhaust fumes come into the cabin on a vehicle that is five years old is concerning and in my opinion, a safety concern.

Oil pans are rusting through . Mine has 45,053 miles. In the 60k mile powertrain warranty. RAM refuses to fix because it is 'corrosion'. They want $1,861.53 to replace. These rusted pans are all over the internet.

Failed Motor Generator @ 74,000 miles while is covered under the Federal emissions warranty. Vehicle has been off road for 30 days with no ETA on replacement parts

I have a 2021 ram 1500 and the belt started to make a lot of noise. I got it to the dealership and they had it a whole month and a half. They said it was the alternator but no it was something called a MGU (motor generator unit). Can't find it no where in the country. Im stuck with a 50k truck that I can drive. Warranty can't fix it and now I can't sleep.

The MPU system was going out caused engine noises, the engine didn't sound like it wanted to change gears i drove very rough to the repair shop, it looks to be like a well known issue on Dodges with Etourqe they are 3 to 6 months behind in parts manufacturing

Bearing bad in mcu e tourqe system no parts and replacements avaliable dealer said been orderd for 6 months and have not received one

There is an exhaust leak at the manifold which lets exhaust gas int the engine compartment and it smells in the passenger compartment. I feel there is a health risk of carbon monoxide poisoning . It seems as though should be a repair made by the manufacturer.

At 45mph the engine cut off. I had to coast to a stop on the side of the road and place the truck into park and then restart the engine. I have already taken the vehicle into the dealership to have recall 37A remediation performed last year.

The Check Engine Light came on and the truck would misfire and stall. We took it to 2 separate mechanics - Mechanic 1 (Certified Sideros Automotive): It was found that the multiple cam shaft lobes were flattened and ground due to a failed lifter, recommendation - replace engine. Mechanic 2 (Stew Hansens Ram): Check Engine Light came on, multiple cylinder miss fire. Using a bore scope inspected cylinder walls, found a very small crak allowing coolant to slowly bleed into the system, recommendation - replace engine We replaced the engine with a rebuilt engine at a cost of $7,677.58. This should not happen to a truck that is only 4 years old. Its a 2021 and the engine was replaced 5/2025. We were not aware of any recalls but we did have the dealership clear all recalls on the new engine such as the engine software update after it was installed.

Cracked passenger side exhaust manifold

Made a turn at 15 mph and the car shut off by itself randomly. This is the fourth time it’s happened since owning the vehicle.

While slowing down to stop at a stop sign the engine shut off on its own. Dash showed message to shift into park once the vehicle stopped. Parking brake also engaged on its own. After shifting into park, restarting the truck, and disengaging the parking brake I shifted back into drive but the vehicle wouldn't move. I shifted into reverse and it would go backwards. Shifted back into drive and it worked properly. It's not safe to have the engine just shut off while you are driving. Also having to put vehicle into reverse before getting it to go into drive is unsafe on a crowded road with vehicles behind you.

Back ordered part: Part # 68623194AB No ETA

The contact owns a 2021 Ram 1500. The contact stated there was rainwater leaking into the rear passenger’s side cabin of the vehicle. The vehicle was taken to the local dealer, who replaced the third brake light and applied sealant; however, the leak persisted. The contact was informed by the dealer that the leak failure may be caused by a faulty frame or window. No further information was available. The contact stated that while operating the vehicle, there was a ticking sound coming from the engine, and while at the dealer the contact was informed that the exhaust manifold was faulty and needed to be replaced. The vehicle was not yet repaired. The contact was informed by an independent mechanic that the bolts inside the exhaust manifold were inadequate and were prone to failure. The manufacturer was not notified of the failure. The failure mileage was 59,700. The VIN was not available.

Was driving at low speed approaching a turn. As soon as I turn the vehicle shut off and I had to restart my truck. It is similar to what happened in this video [XXX] Believe the truck software needs a reflash. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 02/27/2025 my wife drove the 2021 RAM 1500 Limited Diesel truck and the engine certainly stopped running. It happened once around 2:10PM on the freeway I-5 Southbound near exit 189 in WA State. She was on the most inboard lane to prepare to take exit 189 with speed about 45-50 MPH. She was able to pull over to a safe location before the truck had completely stopped. Then she was able to start the engine and go again after 5-10 minutes. She drove for about 4 miles to her work place then the engine certainly stopped running again as soon as she pulled into the clinic parking lot around 2:30PM.
