Vehicle Specs & Maintenance Data
The 2023 Dodge Hornet maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Dodge Hornet.
For oil changes, the 2023 Dodge Hornet takes 5W-20 Full Synthetic motor oil with a capacity of 4.5 quarts. Brake fluid type is DOT 3, the recommended coolant is Mopar OAT (Purple/Violet), and transmission fluid is ATF+4. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Dodge Hornet, torque the lug nuts to 100 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Electrical System Gremlins and Sensor Malfunctions
The 2023 Hornet's electronic suite is its Achilles heel. Owners report interior lights working intermittently, dashboards going completely blank, adaptive cruise control losing function, constant random dinging every 4-6 minutes, and the parking brake setting itself randomly while driving. Warning sensors trigger false alerts without cause.
Update all electronic module software to the latest versions. Many first-year issues have been addressed through OTA (over-the-air) or dealer software updates. TSB 08-001-23 covers infotainment and BCM reprogramming. Replace faulty wiring assemblies identified as factory defects.
Est. Cost: $0 - $800Turbo Engine Performance and Reliability Issues
The 2.0L turbocharged inline-4 engine (shared with Alfa Romeo Tonale) experiences turbo lag, hesitation during acceleration, and in some cases premature turbo failure. Owners report reduced power output, boost pressure leaks, and Check Engine lights related to boost control and wastegate position. Oil consumption may be elevated.
Inspect the turbo system for boost leaks at charge pipes and intercooler connections. Replace the wastegate actuator if DTCs indicate position errors. Full turbo replacement for units with bearing failure. Use only OEM-specified 0W-20 synthetic oil. Monitor turbo oil feed line for blockages.
Est. Cost: $500 - $3,00012V Battery Cable Fire Risk
The 12-volt battery positive cable and/or high voltage connector cable may not be tightened properly from the factory, causing the electrical connections to overheat and potentially result in a fire while parked or driving. Owners may notice electrical burning smell, flickering lights, or intermittent starting issues.
NHTSA Recall 23V-628 (Chrysler recall number 98A) requires dealers to inspect and properly torque the battery cable connections. The repair is performed at no cost. Do not ignore electrical burning smells or intermittent starting problems.
Est. Cost: Covered under recallPremature Tire Wear and Alignment Issues
Owners report extremely rapid and uneven tire wear, with some replacing specialty tires and requiring wheel alignments multiple times within the first two years. The aggressive suspension geometry and lack of factory alignment precision contribute to the problem. Some owners have spent over $9,000 on tires, rims, and alignments.
Get a four-wheel alignment performed immediately after purchase, as factory alignment may not meet specification. Re-check alignment every 5,000 miles. Use the OEM-recommended tire size and maintain proper inflation. TSB 22-005-23 addresses front suspension alignment specs. Inspect control arm bushings for premature wear.
Est. Cost: $150 - $1,500Traffic Sign Recognition and ADAS Software Bugs
The traffic sign recognition feature resets to European mode and reactivates itself every few days, even after the owner turns it off. The system misreads speed limit signs, displays incorrect speed limits, and pesters the driver with false warnings. Other ADAS features including pedestrian detection may also malfunction.
Update the ADAS control module software. NHTSA Recall 23V-240 (Chrysler recall B5A) addresses the pedestrian alert siren that may be missing or disconnected. Software updates resolve the traffic sign recognition European mode bug. Recalibrate the front camera after windshield service.
