Cadillac will provide free servicing for the first four years or 50,000 miles with all 2011 models, adding it wants “to build the best customer service experience in the [US] luxury segment”.

Cadillac Premium Care Maintenance covers scheduled oil changes, tyre rotations, replacement of engine and cabin air filters and a multi-point vehicle inspection.

“Cadillac is adding Premium Care Maintenance as a way to extend customer service beyond the sale,” said the GM luxury division’s sales and service head Kurt McNeil. “The program is designed to raise satisfaction for owners by ensuring access to expert service. It should lead to higher loyalty rates for dealers by establishing them as a valued resource for our customers.”

The CTS line, expanded this model year to include a coupe, will be the first of the 2011 models to arrive at dealerships in late summer.

The brand already offers a five-year, 100,000-mile powertrain warranty with roadside assistance and courtesy transport, four-year, 50,000-mile bumper-to-bumper warranty coverage, a year’s OnStar directions and connections plan and standard satellite radio with free three month trial.

“Cadillac rates among the industry’s best in customer satisfaction, but we have room for improvement,” McNeil added. “[The maintenance programme] is another step in our goal to set the standard for the industry in customer service.”
