2020 Dodge Grand Caravan Transmission Problems

Your transmission may shudder and fail to shift properly while driving, even though no warning light appears on your dashboard. This happened to another 2020 Grand Caravan owner at about 91,715 miles, and the dealer determined the transmission had failed completely. The transmission will likely need to be replaced to fix this issue.

Your 2020 Dodge Grand Caravan experienced transmission failure at 3 years old, causing sudden acceleration while driving at 30 mph. After warranty replacement with an incorrect transmission from a junkyard, the replacement developed a leaking gasket that was later sealed with liquid gasket, but now produces a burning metal smell. The transmission may need to be replaced with the correct Mopar-factory transmission designed for your vehicle's computer system.

Your van rolled backward at 5 mph while parked on level ground, even though the shift lever was in Park and the parking brake wasn't engaged. You were injured trying to stop the vehicle, and it collided with a steel signpost, causing damage to the driver's door, rear quarter panel, and sliding door. The issue may be related to a known recall involving the transmission's power transfer unit, which can wear and fail to hold the vehicle in Park.

Your transmission failed at just under 60,000 miles. Additionally, your airbag warning light is illuminated, though the cause isn't clear. You've also experienced repeated issues with front bolts on the driver's side coming loose. These issues may require transmission replacement or rebuild, airbag system diagnostics, and inspection of mounting hardware.

Your transmission began showing problems around 59,500 miles, but the dealership found nothing wrong during inspection. About 16,500 miles later at 76,000 miles, your transmission completely failed and needed to be replaced at a cost of $5,800. You've noticed online that other owners of this model year report similar transmission failures between 50,000 and 90,000 miles. Fixing this issue requires a complete transmission replacement or rebuild by a qualified transmission shop.

After starting your van with the driver's door open and foot off the brake, your vehicle unexpectedly shifted into reverse and accelerated on its own, dragging you several hundred feet and causing significant injury and property damage. A transmission shop identified a safety recall (W48/NHTSA 20E-037) related to the Power Transfer Unit (PTU) input spline that may have contributed to this unintended reverse motion. The fix will likely involve replacing or repairing the PTU input spline components under the recalled service.

Your engine is misfiring in cylinder #2, which your mechanic believes is caused by low compression in that cylinder. Your mechanic says this doesn't make sense for a vehicle this age with only 70,000 miles and notes this has been a recurring problem across Dodge Caravans. Fixing this will likely require the engine to be partially or fully disassembled to diagnose and repair the compression issue.
