Among the top choices for a full-size pickup, the 2020 Dodge RAM 1500 continues to be one of the main options. It was even rated as the “Best Truck Brand of 2020” by U.S. News & World Report. However, actual owners have something else to say. In fact, this truck suffers from defective air bags, a faulty electrical system, poor visibility, a malfunctioning engine, and structural issues that cause leaks that damage it’s interior.

Most Common Problems with the 2020 RAM 1500

Problems with the electrical system and engine of the 2020 RAM 1500 top the list of complaints on file with the National Highway Traffic Safety Administration (NHTSA). There are also numerous issues that relate to the structure of the truck, many of which relate to leaking water that wreaks havoc with its interior.

Airbags are also a problem, with three airbag-related recalls proving that the manufacturer is well aware of several issues that increase the risk of injury to drivers and passengers. Ironically, airbags are sometimes a victim of leaking water.

Problems with the Airbags

Air bags have become standard on all automobiles, even the cheapest on the road. By now, the system should be completely perfected, but it is not with the new RAM trucks.

One NHTSA complaint states, “Was traveling about 35 mph on a straight road, was hit by a vehicle who sped out of a side road. I was hit on the driver’s side front fender by the car, then I crashed head on into the fuel tanks of a semi truck. My truck hit the semi so hard it through my truck backwards more than a truck length. No air bags deployed.”

Further proving how defective these systems are, let’s look at two air bag-related recalls. NHTSA Campaign Number 20V374000 states that the trucks have a badly crimped diffuser in the side curtain air bag, which could inhibit inflation. Additionally, NHTSA Campaign Number 19V407000 affects nearly 300,000 vehicles and shows that the Occupant Restraint Controller flash memory might be incorrect, disabling the air bags and seat belt pretensioners. From every angle, this truck is failing occupants and putting them at risk. Yet, somehow it is the “Best Truck Brand?” Who did RAM pay off to get that honor?

Problems with the Electrical System

A faulty electrical system can ruin the drive completely, from a comfort standpoint to everyday capability. That’s precisely what is seen with the electrical system in the RAM.

One Edmunds review states, “I purchased a new Ram and the Navigation system doesn’t work. All the 12″ screen Ram truck navigation systems don’t work, and they don’t inform you before you purchase it, won’t take it back, and cannot fix it. Uconnect who makes the system admits it’s a known defect and there is no fix yet. I’ve been fighting this since July and the dealer, nor Chrysler will buy the truck back. Getting a good lawyer and going after everyone who lied, didn’t divulge the truth and won’t take the truck back.”

There is also an electrical system-related recall. NHTSA Campaign Number 20V191000 says that the rearview camera can have a lingering image that distracts the driver and actually increases the risk of accidents. This recall affects more than 300,000 vehicles. Maybe it should have won the award “Best Truck Brand” that has no ability to go in Reverse safely.

Here are some actual complaints logged with the NHTSA about the 2020 Dodge Ram 1500 Electrical Problems:

THE 2020 RAM 1500 EXPERIENCED WHILE DRIVING A “DATA BUS FAILURE”. THIS FAILURE CAUSED THE VEHICLE TO LOOSE POWER STEERING, BRAKES, RAMDOM INSTRUMENTATION DISPLAYS, WIPERS TO COME ON, HEADLIGHTS TO COME ON AND OFF. INTERMITTENT LOSS OF THROTTLE CONTROL. HAPPENED 4 SEPARATE TIME. HAD SHOP ON 3 OF THE 4 TIMES INDICATE A BAD BATTERY, ASB MODULES AND PCM MODULE. CURRENTLY THEY ARE TRYING TO IDENTIFY A BAD TRANSMISSION CONTROL MODULE AS THE PROBLEM. TOTAL MILE 530 AND ONLY HAD THE VEHICLE FOR 50 DAYS. HAD TO BE TOWED TWICE TO THE SHOP AND THE OTHER TWO TIME IT HAPPENED WITH IN A MILE OF THE DEALER. IT SPEND ABOUT 20 DAYS IN THE SHOP ALREADY.

Problems with the Structure & Water Leaks

Water leaks are nothing new for RAM 1500 trucks. The alarming issue is that they recur with every new model. Our post about the 2019 RAM 1500 and water leaks will give you some background.

The manufacturer’s communications on file with the NHTSA about the 2020 RAM 1500 also speak volumes. There are at least 10 of these, all of which include technical service bulletins (TSBs) instructing RAM/Dodge dealers what to do to inspect, repair, or replace affected components.

It’s important to note that it is mandatory for manufacturers to supply copies of all communications to the NHTSA. So, it’s easy for us to keep track.

The first of these manufacturer’s documents was issued on March 16, 2020, and the most recent, on March 4, 2022, more than two years later. Clearly there is a major problem. Also, the water is going everywhere. The titles of manufacturer’s documents speak for themselves:

  • Water Leak Carpet Wet At Front And Or Rear Seats (twice)
  • Water Leak Rear Of Cab Rear Seat Or Headliner (twice)
  • Water Leaks At Sliding Backlite
  • Water Leak At A Pillar Onto Floor
  • Water Leak On Sliding Rear Window Or Back Of Cab
  • Water Leak At Headliner Near Driver Microphone
  • Water is leaking into cab through the third brake light CHMSL (twice)

Similarly, owners of these trucks report water leaking in from various places and causing widespread damage. So, let’s have a look at a few of the complaints made to the NHTSA.

What NHTSA Complaints Say About Water Leaks

“Potential ‘Black Mold’ health exposure due to faulty construction/design/product allowing water to leak into the cab soaking and staining headliner, seats and rugs. The water is absorbed into the insulation and fabrics. Research has confirmed this issue has been reported for more than 15 years.”

“Rear windshield surround cracked. Water is entering (my) vehicle. Concerned about excessive moisture in and around airbags.”

An owner whose warranty has expired tried to claim insurance. But the insurance company blames the manufacturer. “Rear window crack – leaks water into the floor and damages the auto receiver. The vehicle will not start and keys are not operational. Insurance company will not cover and warranties will not cover damages. Insurance company believes it is a design safety issue and needs to be looked into since there are ample complaints on the internet.”

Problems with Visibility

Where visibility is concerned, drivers need to be able to see from every angle behind the steering wheel. But this is just another source of complaint.

One NHTSA review says, “My brand new 2020 Ram 1500 Laramie Sport is equipped with tilting down driver/passenger side mirrors when in Reverse. The problem is when they tilt down, they tilt down so far that it is out of my view. I utilize this feature for backing into my garage, on side on my boat, where space is very limited. I actually have inches on both sides of the truck. After spending big money on my new Ram 1500 2020 Laramie Sport, I expect all of its features to perform as described, and expected. After talking with the salesman who sold me the truck, he explained this is a known problem in the Ram community on these new 2020 vehicles. Knowing this, it frustrates me even more that I was never informed of this information prior to making the purchase. This problem should be fixed immediately.”

Aside from this concern, there is also trouble with the windshield wipers. NHTSA Campaign Number 20V208000 says that more than 400,000 vehicles could have windshield wiper arms that loosen on their own, causing the equipment to stop working. If this happens when it is raining, drivers are in real trouble. Maybe if owners just don’t back up and don’t travel in inclement weather, this could be the Best Truck Brand after all.

Problems with the Engine

Above all, a high-quality full-size truck needs to have a powerful engine. While one would think that the “Best Truck Brand” would also have an exceptional motor, that simply isn’t the case.

Read this Edmunds review for more information. “There are many things about the RAM 1500 Hemi that I like, however all of that is over shadowed by the fact that this engine has major problems with exhaust manifold bolts breaking. I was told it has to do with towing by the dealer and even RAM. We bought it to tow a small horse trailer and one horse, about half of the weight of the advertised towing capacity. I am now on my 3rd, yes third set of broken exhaust manifold bolts. First 2 were covered under warranty, now I have to pocket. RAM offered to pay half of the cost and told me this is a one time only offer, do not contact them if it happens again. They know there is an issue with these engines. I was told by the dealer the kit to fix it would take care of the problem, well it keeps happening. I would highly advise to look elsewhere or go for the diesel if you plan on hauling anything other than some 2×4’s and mulch in the Hemi.”

Among these concerns, Service Bulletin #08-033-20 also calls out trouble starting the engine. Apparently, the ground wire to the engine block can fail, which can lead to this intermittent problem. What part of this truck actually works the way it was designed? At this point, the Little Tikes truck might deserve better ratings.

Here are some actual complaints logged with the NHTSA about the 2020 Dodge Ram 1500 Engine Problems:

THROTTLE RESPONSE OR ACCELERATION LAG AFTER LETTING OFF THE GAS TO CHANGE LANES OR SLOWING FOR CORNERS ETC. HAS HAPPENED AT END OF EXIT OFF THE INTERSTATE AFTER STOPPING AT STOP SIGN, THEN PROCEEDING TO MAKE A RIGHT TURN INTO THE LANE. UPON PRESSING GAS TRUCK SEEMS TO “COAST” OR WAIT A FEW SECONDS BEFORE REALIZING IT’S GETTING GAS THEN WILL SUDDENLY ACCELERATE. YOU HAVE TO WAIT AND NOT GIVE IT GAS FOR A FEW SECONDS FOR IT TO CATCH UP. THIS CAUSES A PROBLEM WHEN CHANGING LANES IN TOWN IN TRAFFIC. APPEARS TO HAPPEN MAINLY AT SLOWER SPEEDS. SUCH LAG COULD CAUSE YOU TO GET REAR ENDED A LOT CAN HAPPEN IN 3 TO 5 SECONDS. HAVE HAD VEHICLE TO SHOP, INSPECTED AND NO SIGNS OF ANYTHING WRONG UPON TESTING. HAS HAPPENED AGAIN, WILL TAKE TO SHOP AGAIN. THIS HAS HAPPENED 5 OR 6 TIMES NOW IN LESS THAN 30 DAYS OF OWNERSHIP. TRUCK NOW HAS 1078 MILES ON IT. *TR

    I have a 2020 ram 1500 limited, the first of alot of issues is the dash leather bubbling up, the wood on steering wheel turning orange, the wheels corroding, the ramboxes warping and lastly the back window leaking through a Crack, I took my truck in to the dealer, August last year, nothing happened, I took it back February this year, they said they ordered parts, kept the truck for a month, nothing happened, I got the truck back and kept calling, they said parts were on order, well I finally called Ram up and said I want to start a lemon law case, I told them what happened and they called the dealer, they called me back and said non of the parts were on order, well they took care of it and in two weeks the part were there, go figure, I am worried something else will go bad now.

  • Sorry b

    Mines a 2020 limited with all the bells and whistles, currently at 12000 and (knock on wood) so far it’s been a great truck. I’ve read about all the problems people are having with them and so far It’s good, well except for the rear view mirror folding down to much to back up and the annoying lane assist keeps shutting off every 3 minutes. Besides that I love it.

Did 18,000 in damages to front end. Hit every thing at between 60 and 65 mph. Not a peep out of air bags any where. Not happy about useless air bags. .

    Well I bought my ram in January 2021 it was a limited 2018 we were driving home from a short drive loved it to the max it burnt to the ground on Good Friday so now we are trying to get our insurance back it was a 3 litre diesel

  • MikeinSonoma

    In reference to the 2021, I have the V6 semi highbred 1500 Rebel and 1000 miles on the truck, first I’m getting about 13.5 miles to the gallon, driving it carefully 2/3 of that country driving.
    My complaint would be what they call lane keep, coming from my 2017 Ridgeline with lane keep… Ridgeline was a PlayStation, RAM is pong. All the technology is their, cameras, control of the steering wheel, but all it does when it sees the line is turn the vehicle toward the other line and pink pong you back-and-forth until the truck rolls, I assume. It has nothing to do with keeping you in your lane. The four your old technology in the Ridgeline, wiggled the wheel if you started crossing the line otherwise it used a little finesse to keep you centered. This is an expensive option in the RAM that you end up turning off because you feel like you’re fighting it’s over correction all the time.
    My Ridgeline and this RAM,!both were made in America, the problem seems to be with the companies not the workers.

  • Robert B

    Was any of this fixed in the 2021 Ram 1500 Laramie’s? I am looking at the Ram 1500 and the Ford F150. Towing a 4000 lb. Boat and Trailer. I really like the Ram, but not after reading about these issues.
