On the 2019-2025 RAM 1500, the 2019+ RAM 1500 equipped with the optional four-corner air suspension system experiences compressor failures, air spring leaks, height sensor malfunctions, and control module issues. The truck may sag on one corner, fail to raise/lower, or display "Service Air Suspension System" warnings. The air compressor (Arnott P-3246) works constantly trying to compensate for leaks, eventually burning out. Cold weather accelerates air spring rubber deterioration. TSB 02-003-21 addresses air suspension height calibration issues. Individual air spring replacement costs $300-600 per corner, compressor replacement is $800-1,500, and a full system overhaul can exceed $3,000.

Common Symptoms

Vehicle sagging on one or more corners
Service Air Suspension System warning
Air compressor running constantly
Truck not raising to proper ride height
Loud compressor noise under vehicle
Uneven ride height side to side
Suspension feels bouncy or unstable

How to Fix

Diagnose with wiTECH to read air suspension fault codes and check height sensor readings. Leak test each air spring with soapy water at all seams and fittings. Check TSB 02-003-21 for height calibration procedure. Replace leaking air springs ($300-600 each, OEM Mopar 68364461AA for rear). If compressor is burned out, replace with OEM or Arnott P-3246 ($800-1,500). Some owners convert to traditional coil springs using a conversion kit ($800-1,200 for all four corners) to eliminate the air suspension entirely.

On the 2019-2025 RAM 1500, the 2019+ RAM 1500 uses the ZF 8HP75 8-speed automatic transmission which exhibits harsh shifting, delayed engagement, hesitation between gears, and rough downshifts. While the transmission itself is mechanically robust, the calibration and TCM (Transmission Control Module) programming have been problematic since launch. Stellantis has released multiple software updates via TSBs to address shift quality. TSB 21-018-22 REV.A addresses rough 1-2 upshift and 2-1 downshift. Some trucks require valve body replacement if software updates do not resolve the issue.

This issue also affects: Acura TL, Mitsubishi Outlander, Acura ILX

Common Symptoms

Harsh or jerky 1-2 upshift
Rough 2-1 downshift when stopping
Hesitation or delay when accelerating from stop
Transmission hunting between gears on hills
Clunking noise when shifting into Drive or Reverse
Delayed engagement when cold

How to Fix

First step: Visit dealer for the latest TCM software update (free under warranty). Reference TSB 21-018-22 REV.A for shift quality improvements. Perform a transmission adaptation reset after the update (dealer procedure). If software updates do not resolve the issue, valve body replacement may be needed ($800-1,500). Ensure transmission fluid is at proper level with correct Mopar ZF 8/9 speed ATF (68218925AB). Some owners report improvements after a complete fluid and filter change ($250-400).

On the 2019-2025 RAM 1500, the 2019+ RAM 1500 with eTorque mild hybrid system (standard on V6, optional on V8) experiences failures of the 48-volt battery pack, belt-driven motor generator (BDM), and eTorque control module. Symptoms include rough idle, stalling at stops, auto start-stop not working, and "Service eTorque System" warning messages. The 48V lithium-ion battery pack located under the rear seat deteriorates over time, especially in hot climates. TSB 08-074-20 REV.A addresses eTorque motor generator unit noise and vibration. Replacement of the 48V battery pack costs $800-1,500 and the BDM unit runs $1,200-2,000.

Common Symptoms

Service eTorque System warning message
Auto start-stop system not functioning
Rough idle or stalling at stops
Vibration or shudder during restart
Check engine light with P0AA6 or U1466 codes
Reduced fuel economy
Clicking or grinding noise from belt-driven motor

How to Fix

Diagnose with a Mopar wiTECH scan tool to identify if the 48V battery, BDM, or control module is at fault. Check TSB 08-074-20 REV.A for motor generator noise. If the 48V battery is degraded (below 42V resting), replace the battery pack under the rear seat ($800-1,500). If the BDM is failed, replace the unit and serpentine belt ($1,200-2,000). Software reflash may resolve intermittent issues. The eTorque system is covered under the powertrain warranty (5yr/60k miles).
