A new study from iSeeCar shows that used electric vehicles from legacy automakers, including GM, are losing momentum among buyers, although interest in electrification remains. The data, which analyzed 6.7 million transactions, shows a clear difference: hybrids and Tesla vehicles are moving, while many non-Tesla electric vehicles are stationary.
It includes several models associated with General Motors. Vehicles like the GMC Sierra EV, Cadillac Escalade IQ, Chevy Silverado EV, Chevy Blazer EV, and GMC Hummer EV are all among the slowest selling used vehicles in the country. Some remained at the dealer for more than 100 days, far exceeding the industry average of 58.8 days. The Sierra EV, in particular, sells on average in 160 days.
“Demand for used cars has weakened over the past year, reflected in falling prices and slowing sales,” he said iSeeCar Executive Analyst Karl Brauer. “In today’s used car market, Tesla and non-luxury hybrid cars are showing the strongest resistance.”
Price trends reinforce this problem. Used non-Tesla electric vehicles fell 10.3 percent year over year in the first quarter of 2026, a sharp decline compared with a 1.4 percent decline in hybrid vehicles and a 2.8 percent decline in gas-powered vehicles. Meanwhile, Tesla’s value is nearly flat. The result is a market where GM electric vehicles depreciate more quickly and take longer to sell.
Compounding the problem is that some new GM electric vehicles are heavily discounted at dealers, reducing the appeal of rarely used vehicles. We found dealer discounts on new GM electric vehicles reaching sky-high numbers $12,500 off MSRP. While a new Silverado EV or Blazer EV comes with aggressive incentives, used versions have to compete on price alone – and often lose out.
Consumer behavior has also changed. “Hybrid cars sell faster, retain more value and increase their market share faster than electric vehicles,” Brauer added. The share of used hybrid vehicles jumped 41.8 percent year over year, while electric vehicle growth lagged.
Buyers seem to prefer a middle ground. Hybrids offer increased efficiency without the charging issues that still impact electric vehicle adoption. At the same time, smaller, more affordable vehicles and Tesla models continue to dominate the fastest-selling rankings.
There are potential benefits for buyers. With inventory increasing and demand weak, dealers may be more willing to negotiate for used GM electric vehicles. For buyers who are comfortable with this technology, it could result in significant savings – if they are willing to accept the market’s current skepticism.
