When driving our vehicle from myrtle beach this week we noticed a smell about half way home that reeked of rotten eggs. the smell was so bad that i because nauseous and develooed a severe headache. after we reached our house and shut off the vehicle the next day i tried to crank the vehicle and it would not crank so after researching the smell and possible causes we bought a new battery for the vehicle and changed the battery ourselves which caused my husband to develop a severe cough and upper respitory problems due to the boiling that was occuring inside the battery. hence the smell of rotten eggs.

The speedometer keeps malfunctioning. the speedometer needle sticks at a higher speed after decelerating or stopping, making it impossible to know what speed you are driving. this happens mostly when the weather warms up, spring/summer/fall. making a hard braking stop, like at an intersection, will sometimes cause the needle to drop back 5-10 mph, as will turning the car off and back on. most specifically, yesterday, may 31, 2019, the speedometer needle wouldn't go back down at all, and my speedometer was "pegged" past the top end of 110mph. i have researched online, and this seems to be a common and chronic issue with this model.
