(AOL Autos) -- With consumer credit ratings plummeting, more American car owners could soon be driving around with an electronic Big Brother on board.
Shut-off devices give audio and flashing light warnings before the vehicle's power is cut.
Business is booming for makers of shut-off devices, which turn engines off when car payments are late. Sales at one manufacturer, Littleton, Colorado-based Passtime, are up 33 percent over last year. CEO Stan Schwarz says the company is cranking up production to meet the demand.
"Right now, we are moving about 2,000 units a month into the marketplace," Schwarz says. "I fully expect by the end of the year we will be up to 14,000 to 15,000 a month,"
While the devices have mostly been used in the subprime auto loan market, other lenders are looking closely at the technology, manufacturers say. It's no mystery why interest in the gadgets soaring: the creditworthiness of American consumers is declining as they lose jobs in record numbers and find it harder to tap into home equity.

Financially stretched consumers have to figure out what bills they are going to pay -- and what payments they have to postpone. And car dealers and lenders want to make sure it's not loan payments that fall to the bottom of the pile. AOL Autos: How to buy a car without negotiating
Consumers could increasingly find themselves in cars with shut-off devices if their credit turns bad and they are forced to shop at dealerships serving the subprime market. These sellers range from small mom-and-pop, "Buy Here, Finance Here" outlets to major dealerships. AOL Autos: Which dealerships treat you best )
According to Schwarz, industry statistics show that 300,000 consumers a month are falling from "A" to "B" credit -- meaning that they have recently been late with a house payment and had other credit problems. Others have fallen lower, becoming candidates for subprime car loans for the first time in their lives. AOL Autos: Inexpensive family cars
It's not an especially nice place to be. Buyers usually end up paying more than they would pay for a late model used car or a new car lease if their credit were good. Since the risks are higher, dealers and finance companies feel they have to hedge their bets by boosting interest rates to 27 percent or more. AOL Autos: Best used cars under $20K
The devices, which are required by a growing number of subprime loan contracts, are the product of a revolution in telematics -- the blending of telecommunications and wireless technology.
The devices are usually controlled remotely by the dealer or lender and are linked to the vehicle's powertrain. They usually cut out the power several days after the payment is due. Before the deadline, the driver is treated to a concert of tones and flashing indicators signaling that the deadline is approaching. There are also warnings after the deadline has passed.
Their proponents call the devices a win-win for consumers and finance companies. They make it possible for dealers to sell cars to people who would have a hard time getting a loan otherwise. The buyers end up paying a somewhat lower interest rate because the risk to the lender is less.
The products also include global positioning, or GPS, to speed up the repossession of the vehicle, if necessary.
Not all the uses of the technology are related to subprime lending: Schwarz said his devices also double as anti-theft measures, making it possible for the consumer to track a stolen vehicle on his own on a computer.
General Motors has introduced a feature using similar technology that enables law enforcement to track a fleeing car and slow it gradually slow it to idling speed when the situation warrants.
The devices used in the subprime market have spawned lively debates about their value and appropriateness, along with Internet chatter about how to disable them -- a move sure to send the repo teams into action. There have been a few lawsuits and scattered complaints about devices shutting down the engine while the owner is driving. Manufacturers attribute the incidents to mechanical problems unrelated to the devices.
Numerous safeguards are built-in, the manufacturers say. The devices won't shut down the engine while the vehicle is moving, and consumers can extend the car's operation in an emergency. Contracts spell out that the device is present on the vehicle.
"We have customers sign a disclosure before they get into the car, saying the unit is on the car and how it is going to function," Schwarz said. "The disclosure form is four or five pages long, and the customer checks off every box.
"If the dealer won't disclose the unit is on the car, then we won't do business with that dealer or his lender or finance company," he said. But the entire system may break apart if dealer doesn't sell a good vehicle, he added. Some customers simply won't make the payments if a vehicle doesn't run reasonably well.
One device, called the On Time, is produced by Murrieta, California-based Sekurus, Inc. CEO Don Lavoie says he joined the company because it was on the verge of going mainstream. He compares the concept to payment plans for cell phones -- people pay on time because they don't want to see their service cut off.
The device basically leads customers to push car payments up their bill-paying hierarchy. "Families across the country, regardless of their financial condition, move the bill to the top of the queue for payment if they need that phone for its basic utility, such as arranging to pick up the kids from soccer or school.
"There are 300 million active cell phone users in the United States, and those people are paying their cell phone bill on time," he said. "And the reason is they can't use the phone if they don't pay for it."
As the economy deteriorates, the shut-off devices seem to be coming into their own. "We have several credit unions that won't finance a car without it," Lavoie says. "They are financing high-quality used cars to non-prime buyers" -- a category that includes both subprime and some other financially challenged segments. A typical member of this group might be described as someone with less-than-stellar credit.
The potential for the market is huge. "There are 40 million used cars sold a year, and 20 million are considered non-prime," said Lavoie.
Schwarz at PassTime is sees similar potential for his products. "Right now we are even talking to national lenders who have "A" credit customers. They would leave the device in the inactive mode unless the customer defaults."
The flexibility of the PassTime devices could accelerate their progress into the mainstream, he says. They can be reset for new payment schedules if owners run into a problem, giving them extensions of a few days at a time if the buyer can only afford to make partial payments. In the meantime, the borrower and lender could conceivably work out a new payment plan.
In one more example of how cars are developing minds of their own, GM recently introduced its "Stolen Vehicle Slowdown," as an option on a number of models, including the Cadillac Escalade and the Chevrolet Silverado. The automaker is in the process of making it available on all its model lines.
If the vehicle is stolen, customers call OnStar, and its staff locates the vehicle using a GPS device and then gives police the location, says James Kobus, a communications manager at the company.
"If the police start closing in, and they notify us that the conditions are right, we can slow that vehicle down." A light on the instrument panel signals "Engine Power Is Reduced" and the car idles down to about three miles per hour.
