It was a mixed bag of results for the Japanese Big Three automakers in March, as their U.S. sales results diverged.

Toyota posted a 9.9% decline, adjusted for 27 selling days last month compared with 25 in March 2015.

Toyota and Lexus car lineups both fell sharply, with every Toyota Div. car in the red, causing a 15.6% overall car loss. Lexus cars slipped 20.8%.

While Toyota executives by and large blame the shift in Americans’ preference for CUVs and SUVs, other factors were at play in the March losses.

“March has shown a little bit of softness due to consumers being a bit more cautious about spending,” Bill Fay, group vice president-Toyota, tells media on a call to discuss sales results.

Fay and his colleague, Lexus Group Vice President Jeff Bracken, also cite Easter weekend as detrimental to their respective brands’ March figures. About two-thirds of Lexus’ U.S. dealers were closed Easter weekend, Bracken says.

“To see the volume off, albeit slightly, was certainly not our plan,” he says. “(But it’s) not a sign of any kind of sustainable issue.”

Toyota saw a reduction in core models Corolla, Camry and Prius, down a respective 15.2%, 16.1% and 30.3%.

Fay says Toyota is readjusting the mix of Corolla and Camry output, but not reducing production of either model despite consumers continuing to clamor for utility vehicles.

The new ’16 Prius liftback made up 90% of the 8,130 March deliveries of the body style, he says.

All Scion models were down from year-ago, although the new iA and iM added roughly 4,900 units, putting Scion in the black for March. Scion ceases existence with the ’17 model year.

All Lexus cars save for the low-volume LFA, which recorded two deliveries last month vs. one year-ago, were down last month. The GS had the steepest loss, 40.6%.

Toyota truck results largely were positive, but the Sienna minivan’s 13.6% decline and the Tundra large truck’s 19.5% loss were enough to bring total truck deliveries down 3.4%.

The RAV4 compact CUV continued to be bulletproof, up 6.5% to a March record of 29,045. Some 3,073 of that figure was the new hybrid RAV4.

Tacoma compact pickup sales rose 3.1%, with Fay noting Toyota continues to prioritize Tacoma over Tundra production at its San Antonio plant.

Lexus CUVs and SUVs inched up 1.4% collectively as the NX, RX and LX offset a rare decline of the GX, which has been going strong for two years now since a ’14 refresh and price repositioning.

Toyota Div. ended March with a 49-day supply at dealers and ports, while Lexus finished with a 50-day supply.

Fay cites Toyota’s 40-day supply of light trucks late last month as being too low and says the automaker continues to try to get more units out of its plants.

“We’re trying to get as much RAV4, Highlander light-truck production as soon as we can,” he says.

For Q1, Toyota sales of 569,079 were down 1.1% from Q1 2015, WardsAuto data shows.
