The equipment installed kills your car! Drains the power completely from the car battery, the starter, and including the alternator. Intoxalock said you have to start your car evey 8 hours for at least 5 minutes to prevent the car battery from being depleted. Lies!!! I have to start it every 4-6 hours and sometimes that's still not enough. I have a new starter ($748) and new battery. The alternator was new when the intoxalock equipment was installed. I've replaced my battery again ($189) and had to invest in a handheld chargeable battery jump starter ($60). I've been stranded in a hurricane. I've been stranded in extreme heat. It's not safe to have children in the car with this device. The equipment has you retest with new breath samples while driving but what do I do when the 5 minute sync warning flashes counts down to 0 and starts over at 5 minutes, for 10 hours straight. So technically anyone with this intoxalock device could drink alcohol while driving for 10 hours straight without a breath test. I recorded the entire ordeal. But intoxalock and the garage that installed it say it's never the equipment there's something going on with your car. Customer safety is not a priority.
