Plug-in hybrids (aka PHEVs) have been round for some time now. Meaning the cutting-edge automobiles of some years in the past are actually coming off leases and ending up on used automotive heaps. A used PHEV could be tempting, particularly with (not less than for now) the potential eligibility for a federal tax credit score. However the prospect may additionally trigger extra trepidation than a typical used automotive buy.
PHEVs are extra difficult than combustion vehicles — and have problems consumers aren’t acquainted with. Some high-profile PHEVs have been topic to remembers and suffered reliability points. Battery know-how and the market are additionally evolving. So, we don’t know exactly how PHEVs will age and the way a lot consumers will worth them once they do.
As with every used automotive buy, potential consumers should do their due diligence and reply some crucial questions earlier than continuing.
How do you propose to cost and drive the PHEV?
The primary pure query when shopping for a plug-in hybrid: do you want one? A plug-in hybrid can seem to be the “better of each worlds” on paper. However principle differs from apply.
The optimum atmosphere for utilizing a PHEV — quick journeys, handy plug entry — overlaps closely with the optimum use case for an EV. Purchaser concern or being unable to purchase the kind of automotive desired (a used three-row household minivan, for example) as an EV would be the cause to go PHEV.
Alternatively, if a purchaser has a reliable concern that will preclude an EV — prolonged roundtrip commutes or lengthy street journeys — a standard hybrid would probably ship nearly as good if not higher effectivity, value much less up entrance and be much less of a nuisance.
PHEVs could make quite a lot of sense and be very environment friendly — when you possibly can cost them commonly with common plug entry. Helpfully, consumers don’t want to put in a Degree 2 charger. Many PHEV batteries could be charged in a single day on an ordinary 110V wall outlet. Ideally, the manufacturer-provided charging cable is in working order. If not, consumers can sometimes buy a third-party transportable charging cable for between $100 and $200.
Is the used PHEV eligible for the federal tax credit score?
For now, a used plug-in hybrid can nonetheless be eligible for a federal clear automobile tax credit score value as much as $4,000. The automobile and the customer should meet sure thresholds to qualify.
The automobile should be offered from a seller, be priced at or beneath $25,000 and should be not less than two years out from the calendar 12 months wherein it’s purchased (in 2024, it must be the 2022 mannequin 12 months or older). The PHEV’s battery pack will need to have a capability of not less than 7 kWh and a GVWR beneath 14,000 kilos.
The federal tax credit score is income-limited for the customer. A purchaser might not have earned greater than $150,000 as a joint filer, $112,500 as a head of family or $75,000 as a person.

How a lot battery guarantee does the used PHEV have?
Changing a battery on a plug-in hybrid is a uncommon prevalence. The failure charge on PHEV batteries in automobiles in-built 2016 and later — not counting recalled automobiles — is “nicely beneath one p.c.” But when you want to change the PHEV battery, it’s a restore that may value a number of thousand {dollars}. And it’s one thing you’d ideally need to do beneath guarantee.
PHEVs sometimes have bumper-to-bumper and powertrain warranties much like these of combustion automobiles. However many more recent ones even have battery warranties stretching to 100,000 or even 150,000 miles. A battery guarantee is nice for peace of thoughts when shopping for a used PHEV. It also needs to assist defend resale worth on the again finish if the customer doesn’t maintain the automobile previous that 100,000-mile mark.
Has the PHEV battery degraded over time?
All batteries degrade over time. However degradation shouldn’t be an excessive amount of of a priority when shopping for a used plug-in hybrid — not less than a current classic one. Automobile batteries are lasting longer than producers initially feared. Charges of degradation rely upon the person automobile and aren’t at all times linear. However broadly, a PHEV battery ought to keep within the usable vary (not less than 70-80% of its preliminary capability) previous 100,000 miles.
PHEV batteries, particularly, are designed to be resilient. Most PHEV batteries have quite a lot of unused capability. That lets the PHEV battery, always being stuffed to 100 and drained to 0, keep inside a cheerful working vary and place much less stress on the battery.
Vary loss additionally issues much less for PHEVs than EVs. Let’s presume a battery experiences a ten p.c vary loss. An EV providing 225 miles of vary as a substitute of its preliminary 250 miles is a much bigger deal than a 27-mile vary PHEV providing 24 miles earlier than the fuel engine kicks in.
Testing degradation your self will likely be tough; most sellers gained’t allow you to borrow the automotive, drain the battery with simulated every day utilization, and evaluate it to anticipated outcomes. The dealership ought to be capable of present a battery well being check to find out the state of the automobile’s battery. Failure to try this ought to increase suspicion. So ought to a posted vary determine on a full cost that appears far lower than what it must be.

Do you propose to drive your used PHEV in chilly climate?
Like full EVs, plug-in hybrids can lose all-electric vary in extraordinarily chilly climate. Like in EVs, the primary offender is heating the cabin, which is difficult to do effectively. Warmth pumps permit a automobile to heat the cabin extra effectively. However that know-how is comparatively new for full EVs, not to mention PHEVs.
Some PHEVs use an electrical heater, which saps energy and, consequently, vary from the battery. Different PHEVs don’t have an electrical element for heating and run the gasoline engine when wanted to warmth the automobile. Both manner, you possibly can lose a lot of the effectivity you sometimes would acquire driving a PHEV, particularly an older PHEV with lower than 20 miles of vary.
Has the used PHEV been appropriately serviced?
Service historical past is crucial when shopping for any new automotive. A plug-in hybrid could be the worst of each worlds from a service perspective. You might have intricate and costly battery packs and electrical motors like an EV. However in contrast to an EV, you even have all of the transferring components and conventional upkeep required for a combustion automobile.
Guarantee the vendor has detailed, up-to-date service data and that needed companies have been carried out. Like EVs, PHEVs could be tougher on their tires than combustion automobiles with the extra weight. Make sure the tires are in good situation and formulated to deal with the additional burden from the plug-in hybrid.

Has the PHEV’s software program been up to date?
All vehicles are de facto tech merchandise now. Many fashionable reliability points are going to be software-related somewhat than mechanical. You need to be sure that a used PHEV has put in all of its software program updates and that the interface works appropriately.
A more moderen infotainment system — much less more likely to be outmoded and extra more likely to be supported with updates — is best than an older one. The aptitude to do over-the-air software program updates and not using a journey to the seller can be useful.
Conclusion: Must you purchase a used plug-in hybrid?
A plug-in hybrid mustn’t scare used automotive consumers off in a vacuum. Sure, a PHEV will lose effectivity and efficiency because it ages. However so do combustion automobiles. The anticipated lifespan for the battery isn’t that far off most combustion engines. With due diligence, consumers could be assured about what they’re shopping for. The last word query with a used PHEV isn’t a lot whether or not shopping for one is prudent however whether or not a PHEV is the automobile you want.
If a purchaser does go for a used PHEV, the perfect technique is to search out the latest automobile with the least put on and tear accessible inside the finances. PHEV tech has develop into extra succesful and extra resilient lately. An extended remaining lifespan means higher worth, whether or not meaning an extended possession tenure or higher back-end resale worth.
