Chrysler and Dodge vehicles have a loyal following in Oklahoma, and for good reason — they offer powerful engines, capable trucks and SUVs, and often excellent value. Like any manufacturer, Chrysler (now Stellantis) has a pattern of known issues that recur across models and years. Understanding these patterns helps owners catch problems early and avoid expensive repairs. At Norm’s Auto Clinic in Coweta, Oklahoma, we service all Chrysler and Dodge vehicles and are well-acquainted with the issues discussed in this guide.
TIPM (Totally Integrated Power Module) Failures
The TIPM is the most widespread and costly known issue across Chrysler/Dodge/Jeep/Ram vehicles from roughly 2007 through 2019. It’s a central electronic module that controls power distribution to nearly every electrical system in the vehicle. When it fails — partially or completely — the results can be bewildering:
- Vehicle won’t start or cranks but doesn’t fire (fuel pump relay failure within TIPM)
- Horn honking randomly, especially in parking lots
- Wipers running on their own or not functioning
- Fuel pump running after the vehicle is shut off (drains battery)
- Random airbag warnings, ABS lights, or other warning lights
- Power window or door lock failures
- Starter relay failure (no start, clicking only)
TIPM failures are common on: Dodge Grand Caravan (2008–2014), Chrysler Town & Country (2008–2014), Dodge Charger and Challenger (2011–2017), Dodge Durango (2011–2018), Jeep Grand Cherokee (2011–2019), and Ram 1500/2500 (2011–2018).
The repair: OEM TIPM replacement ($500–$900 + programming), aftermarket refurbished TIPM ($200–$400), or TIPM repair services that target the specific relay or circuit that has failed (often the most cost-effective path). We diagnose TIPM issues in-house and can recommend the right approach for your vehicle and budget.
3.6L Pentastar V6 Issues
Chrysler’s 3.6L Pentastar V6 is used in virtually every FCA vehicle including the Charger, Challenger, 300, Durango, Grand Cherokee, and Ram 1500. It’s a good engine overall, but has documented issues:
- Rocker arm and camshaft failures (2011–2012 engines): Early production Pentastars had inadequate lubrication to the rocker arms, causing premature wear and eventual camshaft damage. A ticking noise from the top of the engine is the warning sign. Addressed under warranty on original owners; out-of-warranty repairs can run $800–$2,000.
- Coolant leak at thermostat housing: The plastic thermostat housing where it meets the water pump can develop cracks or gasket failures, particularly on 2011–2014 vehicles. Watch for coolant smell or visible residue near the front of the engine.
- Intake manifold runner failure: On some Pentastar variants, the intake manifold runner control (IMRC) actuator can fail, causing rough idle and a P050D or related code.
5.7L HEMI Issues
The 5.7L HEMI found in the Charger, Challenger, 300C, Durango, and Ram 1500 is an excellent engine — but the Multi-Displacement System (MDS) that deactivates 4 cylinders at cruise speed is sensitive to oil maintenance. MDS lifter failures are the primary HEMI concern:
- Ticking or knocking at idle that may go away under load
- Multiple cylinder misfire codes (P030X)
- Rough idle or shaking
- Check engine light with cylinder-specific misfire codes
Prevention: change oil every 5,000 miles with full synthetic. Diagnosis and repair: lifter replacement runs $800–$2,500 depending on how many are affected. Always use the correct 5W-20 oil viscosity — heavier oils are not recommended for MDS engines.
Chrysler/Dodge Transmission Issues
Several Chrysler/Dodge transmissions have known issues worth mentioning:
- 62TE 6-speed automatic (minivans, 2007–2020): The Chrysler Town & Country and Dodge Grand Caravan’s 62TE transmission is generally robust but requires fluid changes every 30,000 miles to prevent solenoid wear and slipping. Neglect leads to harsh shifting and eventual failure.
- 8HP70 ZF 8-speed (Charger, Challenger, Ram, 2014+): Excellent transmission that can shudder or hunt gears when fluid is degraded. Fluid change with the correct fluid spec (ZF Lifeguard 8 fluid) and software update resolves most complaints.
- NAG1 (5-speed automatic in 300/Charger/Jeep, 2005–2011): Generally reliable but can develop shifting problems with degraded fluid. 30,000-mile fluid changes are recommended.
Cooling System Problems
Chrysler vehicles across many eras are prone to cooling system issues, largely due to plastic components that degrade over time:
- Plastic radiator tanks cracking and leaking — particularly on vehicles over 100,000 miles
- Thermostat housing failures (as noted above for Pentastar engines)
- Water pump seal leaks — more common on higher-mileage vehicles driven in Oklahoma’s heat
- Coolant hose failures at clamp connections on older models
Oklahoma’s summer temperatures accelerate plastic cooling system component degradation significantly. We recommend proactive radiator and hose inspection at every oil change for Chrysler/Dodge vehicles over 80,000 miles.
