In Paduano v. American Honda Motor Co., Inc. (2009) 2009 WL 57806, the California Court of Appeal held that Federal law (the Energy Policy and Conservation Act) specifying the use of EPA estimates of mileage preempts breach of warranty claims based on a Hybrid vehicle’s failure to achieve EPA mileage estimates. However, the EPCA did not preempt claims under the CLRA and UCL for false advertisements claiming that the high EPA mileage could be achieved by normal driving when — as the plaintiffs asserted — the hybrid had to be driven differently to get the mileage advertised.
