General Motors (GM) has announced a customer satisfaction campaign affecting approximately four thousand 2013 Chevrolet Volt electric cars. A software glitch in the delayed charging function could cause the vehicle to unexpectedly stall. Drivers will still have steering and brakes, but in order to restart the engine, they must stop the vehicle, turn it off, and wait five minutes before restarting.

According to GM spokeswoman, Michelle Malcho, the glitch only affects the small number of owners that have used the delayed charging option. All drivers are recommended to switch to immediate instead of delayed time charging until the problem can be fixed. GM has already sent letters by Federal Express explaining to customers that the repair requires the vehicle’s control system software to be re-flashed. The repair is expected to take less than an hour.

Two recent lemon law buybacks of Nissan Leaf vehicles in Arizona have Leaf owners in California questioning whether their vehicles can be repaired, replaced, or bought back under the California lemon law.

Approximately 400 Nissan leaf owners in Arizona are claiming that after only a year of driving in warmer than normal temperatures have contributed to a significant loss of driving range in their electric vehicles (EV). One owner said that after only 15 months, his vehicle lost almost 30% of battery capacity giving him a maximum of only 42 miles on a single charge.

In a statement released by David Reuter, Nissan’s vice president of corporate communications, the problems are limited to “a small handful” of Leaf owners, and the vehicles in question were impacted by extreme heat, high speeds, high mileage, and charging method and frequency. He added that there is no defect in the Leaf, but in the interest of customer satisfaction, Nissan bought the cars back. According to Reuter, there have been over 38,000 Leafs sold around the world and the majority customers are very satisfied owners.
