LONGER WARRANTIES ON NEW CARS keep causing problems for auto makers . . . most models are guaranteed against parts failures for five years or 50,000 miles, whichever comes first. Six years ago, it was three months or 3,000 miles. The extended warranties have boosted manufacturers' costs sharply, angered some dealers, and drawn attention of the FTC. The agency is looking into re­quirements of car makers that buyers have periodic checkups to keep warranties in force. Total industry cost of warranties, which doubled to $700 million last year from the 1962 figure, is expected to rise by $200 million this year. Some dealers complain that auto makers don't reimburse them enough for repairs made under warranties. The dealers also bristle at making repairs on cars bought from competing dealers.

ALL 1968 GM CARS WILL BE EQUIPPED with two features to help pre­vent theft of the vehicle. One is a buzzer which will sound when the driver leaves the car with key still in the ignition. The second is a system of vehicle identification numbers on the instrument panel, engine and transmission. GM also plans an in­creased use of key-lock combinations to make illegal entry into cars more difficult. The buzzer device is activated when the driver's door is opened, with key left in the ignition. Instrument panel numbers will be visible through the windshield, allowing police and theft investigators to identify the vehicle without having to enter the car.

POSI-TRAC SAFETY TIRE CORP, of Michigan, headed by former Chrys­ler president, William C. Newburg, and Posi-Trac Rail, Inc., Houston, have agreed to a merger. "This move," according to Newburg, "foresees a government edit requiring that 1969 model cars be equipped with a means, when tires fail at high speeds, for retaining a deflated tire on the wheel and bringing the vehicle to a stop without skidding or swerving, and without need for more than normal-condition driving skills."

THE RUBBER MANUFACTURERS ASSOCIATION has called for a national inspection standard which would remove from the road all tires with less than 2/32nds of an inch of tread depth. The Associ­ation issued its call in conjunction with publication of a revised tire inspection guide which lists six tire conditions suggested as cause for rejection by state highway inspection agencies and policing authorities. Of the 20 states and the District of Columbia which require motor vehicle inspection, 17 require tire inspection, and only 5 of these specify a 2/32nds inch tread depth minimum, while 12 merely prohibit use of "unsafe" tires, without adequate definition as to what "unsafe" means. The five states requiring 2/32nds of an inch are New York, New Hamp­shire, Massachusetts, Vermont and Pennsylvania.
