Common Problems and Reported Issues in the 2021 Ram 1500
Owning a 2021 Ram 1500 comes with the expectation of dependability, but several commonly reported problems have surfaced among owners and industry observers. Understanding these issues by category can help you recognize symptoms early and seek proper repairs.
Engine Problems
- Stalling and Misfires: Some owners have reported intermittent engine stalling and misfires, often traced back to faulty cam sensors or issues within the ignition system (source).
- Excessive Oil Consumption: Higher mileage units have experienced rapid oil consumption, commonly due to a faulty intake manifold plenum gasket. If not addressed, this might lead to knocking and serious engine damage.
- Overheating: Overheating incidents have been connected to coolant leaks and malfunctioning water pumps, posing a risk of severe engine damage if neglected.
Transmission Issues
- Rough Shifting and Hesitation: Multiple reports cite rough transmission shifting, hesitation during acceleration, and—more seriously—episodes of complete transmission failure (source).
- Causes: Problems may stem from defective transmission control modules or worn internal components.
Electrical System Failures
- TIPM Defects: The Totally Integrated Power Module (TIPM) is a known trouble spot. Failures lead to random issues: stalling, power window or door lock malfunctions, and fuel pump problems (source).
- Battery Drain: Some drivers have experienced unexpected battery drain, often related to wiring issues or faults in the power distribution system (source).
Brake and Safety System Malfunctions
- Emergency Brake Engagement: The most widespread and potentially hazardous complaint involves the emergency brake activating while driving, particularly in the first 10,000 miles (16,093 km) (source).
- Brake Pedal Issues: A missing component in some 2021 models resulted in brake pedals detaching from the system, a serious safety issue (source).
Uconnect Infotainment System Problems
- System Crashes and Black Screens: Owners report the Uconnect touchscreen freezing, shutting down, or displaying only a black screen. This locks out radio, navigation, and climate controls (source).
- Other Issues: Backup camera glitches, Bluetooth drop-outs, wireless CarPlay failures, and lost radio presets are frequently mentioned.
Air Suspension Issues
- Leaks and Compressor Failure: Vehicles equipped with air suspension can develop leaks or see compressor failures, affecting ride comfort and handling (source).
Fuel System Problems
- Injector and Pump Failures: Some trucks exhibit rough idling, poor acceleration, and hard starts due to faulty fuel injectors, fuel pumps, or lines (source).
Steering Issues
- Loose Steering: Reports indicate that a loose or excessively worn steering wheel can make maintaining vehicle control difficult, especially at speed (source).
Recent Recalls
- Brake System Software Malfunction: In September 2024, a recall was issued for about 1.23 million 2019–2024 Ram 1500 trucks in the U.S. due to anti-lock brake system software malfunctions, increasing crash risk (source).
These issues highlight the significant value of regular inspections and timely repairs for your 2021 Ram 1500.
