Still curious if there is anything new on this out there. Last summer I parked by 2019 Honda Insight in a garage for 5 weeks and came back to a dead car. A jump start, 20 miles later and parked overnight found it dead again. Another jump start and 60 miles of driving got it going for the next 6 months. Here it is April. 2 weeks parked and it turns up dead. A jump start and 20 miles left it dead again 4 hours later.
Heading back to the dealer in the am. Hoping to find a car that works.
What should I do to prepare my Honda vehicle for long-term storage (more than 1 month)?
Long-term vehicle storage can be required for a variety of reasons. It is mainly beneficial for Honda owners who might be traveling, serving in the military, or are simply preserving their infrequently used car. To ensure the vehicle operates smoothly once it’s running again, certain instructions must be followed and maintenance should be performed. Storing a vehicle improperly can ultimately lead to serious damage, both inside and out.
American Honda’s minimum recommendation for long-term storage of conventionally-powered vehicles are listed below:
Tools and supplies needed:
- Engine oil and filter
- Tire pressure gauge
- Tire pump
- Floor jack
- Jack stand or block
- Towels or shop rags
- Vehicle cover
Instructions before storing the vehicle:
- Fill up the fuel tank with the appropriate gasoline specified in the owner’s manual
- Replace the engine oil and filter
- Wash and dry the exterior completely
- Clean the interior; make sure carpeting, floor mats etc. are completely dry
- Block the rear wheels to avoid any slippage or movement
- Cover any gaps, such as an exhaust pipe or an air intake, to ensure critters are not able to enter
- If there are any paint chips, have them repaired
- Replace the engine coolant, if needed, at the time of storage
- Support the front and rear wiper blade arms with a folded towel or rag so they do not touch the windshield
- To minimize sticking, apply a silicone spray lubricant to all door and tailgate seals; also, apply a vehicle body wax to the painted surfaces that mate with the door and tailgate seals (please see a Honda dealer for fluid recommendations)
Instructions when storing the vehicle:
- Leave the parking brake off; put the transmission in Reverse (manual) or Park (automatic)
- Disconnect the 12-volt battery cable
- Operate the engine at the normal operating temperature specified in your owner’s manual for 15 minutes before turning off the engine
- Cover the vehicle with a “breathable” cover, one made from a porous material such as cotton (non-porous material, such as plastic sheeting or trap moisture, can damage the paint)
- If stored in a temperate, ventilated garage (indoors), the windows can be left slightly open
- If possible, run the engine monthly until it reaches full operating temperature (the cooling fans should cycle on and off twice); this will ensure proper lubrication
- If the vehicle is stored longer than 1 month, raise the vehicle on a level surface and place on jack stands or blocks to prevent flat spots on the tires
- For hybrid owners, reconnect the 12-volt battery and drive your vehicle every month for about 30 minutes ; this will keep the IMA battery charged and in good condition (if a hybrid vehicle is unused for over one month, the service life of the IMA battery will be reduced and the battery may become permanently damaged)
Instructions for bringing the vehicle out of storage:
- Have the 12-volt battery charged and reconnect the battery cable
- Check the fluid levels and add/replace, as needed
- Check for any leaks underneath the vehicle
- Check and inflate the tires to the correct pressure before taking the vehicle off the jack stands or blocks
- After starting the engine, observe the warning lights; if any are illuminated, have the vehicle inspected by your Honda dealership
- Check the brake pedal for normal feel (height and firmness) before shifting the transmission
- Take the vehicle to your Honda dealership for general inspection
Note: If you are planning to store your vehicle for more than 6 months, please consult with an authorized Honda dealership.
^I found the above from Honda's FAQ site. It might be better to disconnect the 12v AGM battery if you don't plan on driving your Insight for awhile. I've also read that if an AGM Battery is allowed to fully discharge it can hurt the overall life of the battery unlike regular 12v flooded batteries.
I've been driving(5-10 miles) my Insight twice a week on the highway then back home to keep both batteries(12v AGM & Lithium-ion) healthy.
