“While stopped (engine still running) at a gas station, the driver side airbag and driver side side curtain airbag both went off. The battery disconnect feature was also triggered. Very lucky I wasn't driving when this occurred.”Owner report · Air Bags · May 2021
“White steam was coming from under the hood onto the front windshield. The steam was fogging the windshield, and causing poor visibility while driving 50-55 mph. Consumer was able to get the vehicle to a repair shop. Dealer informed the consumer that the upper neck connector of the radiator hose broke.*ak”Owner report · Engine And Engine Cooling · Jan 2005
“2nd catastrophic radiator failure. Not a leak, the neck breaks off causing immediate loss of cooling. 1st radiator at 45k, 2nd at 92k. Based on other's experiences, this is very common for this model (and even longer life than many). Causes loss of vision due to amount of steam released. Less experienced driver may have difficulty controlling vehicle to get to side of road quickly to shut down. No way to predict the failure. Same issue with expansion tank. Both failures are on plastic parts.*ak”Owner report · Engine And Engine Cooling · Feb 2004
