After driving a short distance to exit a parking lot and waiting for an opening in traffic on a busy four-lane road with a speed limit of 50 mph, I hit the gas to accelerate into an opening and nothing happened, no forward motion. And there have been subsequent incidents; one involved trying to cross a busy street from a stop sign. This is a definite safety issue; when the drive train is unresponsive in such circumstances, people could be injured or killed. Today, I took my vehicle to a Nissan dealer for an oil change and to have this anomaly checked out. They have informed me the radiator cracked, leaked coolant into the automatic transmission, and both must be replaced. This is being done at no cost to me, as there is a known issue with the radiator cracking for which Nissan has increased the warranty to 8 years or 80,000 miles. However, the warranty notification doesn't mention the transmission may be compromised, stating only, "in vehicles equipped with automatic transmissions, a crack in the radiator assembly might occur at higher mileages leading to internal leakage of engine coolant. " my vehicle is four years old and just hit 12,000 miles.
