DETROIT, Oct 3 (Reuters) - Major automakers on Tuesday posted higher U.S. new vehicle sales in September as consumers in hurricane-hit parts of the country replaced flood-damaged cars, extending a rally in their shares that began when Hurricane Harvey hit southeast Texas in late August.
Analysts and industry consultants had predicted hurricanes Harvey and Irma would provide automakers with their first monthly gains in 2017. Sales had been weak after a strong run since 2010 that culminated in record sales of 17.55 million units in 2016.
But others warned high inventory levels and record consumer discounts remained a concern moving forward.
While U.S. sales rose beyond the storm zones, according to automakers and dealers, much of the September gains came after Hurricane Harvey-hit Texas. Replacing cars during the recovery in southeast Texas and Florida will boost U.S. new and used auto sales through at least November, according to industry consultants.
GM BENEFITS IN PARTICULAR
General Motors Co stock rose as much as 3.7 percent to its highest since its 2010 post-bankruptcy initial public offering, and Ford Motor Co was up more than 2 percent.
While the hurricane recovery drove sales, "this will be a short-lived party," said Michelle Krebs, executive analyst for online sales site Autotrader.
As many as 500,000 cars were damaged or destroyed during Harvey and another 200,000 cars during Irma, according to industry estimates.
GM's sales jumped nearly 12 percent versus September 2016 as a 43-percent increase in sales of crossovers and a 10-percent rise for pickup trucks offset an 11-percent decline for passenger cars.
The No. 1 U.S. automaker's inventory fell to 76 days supply last month from 88 days in August, a positive development since analysts have blamed the automaker for much of the industry's oversupply of unsold new vehicles. GM is moving closer to its goal of around 70 days supply by the end of the year.
The "overall strength of the U.S. economy is the main force driving the market," said GM chief economist Mustafa Mohatarem, with recovery in hurricane-damaged areas "spurring new and used vehicle sales."
GM said new car sales to consumers were up 14 percent in the region that includes Texas.
Industrywide, new car sales in the Houston area, the fourth most populous U.S. city, soared 109 percent in the three weeks after Hurricane Harvey compared with the three weeks before the storm, according to car shopping website Edmunds.com.
GROWTH NOT RESTRICTED TO TEXAS AND FLORIDA
Meanwhile, Ford sales rose 8.7 percent in September, with those to consumers up 4.4 percent and lower-margin fleet sales up 25.1 percent. F-Series pickup truck sales soared 21.4 percent, benefiting from the popularity of pickups in Texas.
However, increases weren't restricted to hurricane-ravaged areas.
Galpin Motors President Beau Boeckmann told Reuters his dealerships in southern California experienced solid Labor Day sales "but what was great was that we continued to see momentum throughout the month."
Boeckmann said new Ford sales were up 28 percent in September, while Honda sales rose 20 percent. Galpin, with 11 dealer franchises in southern California, is Ford's No. 1 U.S. dealer and Honda's No. 2.
Toyota Motor Corp's September sales increased nearly 15 percent, with strong gains for SUVs and trucks. Sales of the revamped 2018 midsize Camry sedan were up 13 percent in its first full month of sales.
Honda Motor Co Ltd's September sales rose almost 7 percent, with the redesigned Accord hitting dealerships now.
Toyota and Honda are betting the new sedans win market share as their Detroit rivals shift focus to SUVs, crossovers and pickups.
Fiat Chrysler Automobiles NV (FCA) reported a 10-percent decline in sales, driven by a 41-percent drop in lower-margin fleet sales. The company is cutting back on fleet sales. FCA's sales to consumers rose 0.3 percent.
Nissan Motor Co Ltd's September sales rose 9.5 percent. Judy Wheeler, vice president of U.S. sales, said while Houston area sales were up around 11 percent, results in most of its regions were also higher "so it wasn't just the hurricanes that affected us."
GM and Ford stocks helped boost U.S. indexes to new highs on Tuesday.
Since Harvey made landfall, GM stock has risen 24 percent, Ford is up 16 percent and Fiat Chrysler Automobiles NV (FCA) has rocketed 44 percent.
