General Motors is recalling more than 193,000 vehicles on the US market to fix a variety of safety defects, including brake problems, US federal safety regulators said today.

The UK is not thought to be affected.

The US National Highway Traffic Safety Administration (NHTSA) said the recalls include 155,465 pickup trucks, sport utility vehicles and vans that may suffer hydraulic fluid leaks, causing increased steering and braking effort and potential crashes.

Vehicles affected, all from the 2004-05 model years, are the Avalanche, Express, Kodiak, Silverado and Suburban from GM's Chevrolet division.

GMC's Savana, Sierra, Topkick, Yukon XL and the Hummer H2 were also affected, NHTSA said.

It said the potential hydraulic leaks were caused by a faulty component in hydro-boost brake assemblies from Bosch.

Separately, the agency said 19,924 Cadillac SRX and Cadillac XLRs, along with Pontiac Grand Prix models from the 2004 model year, were being recalled because of potential problems with their accelerator pedals.

NHTSA said GM was recalling 17,815 Buick Rainier, Chevrolet TrailBlazer, GMC Envoy and Isuzu Ascender SUVs from the 2005 model year because their windshields may not have been mounted properly.

GM, the world's largest automaker, recalled more than 10 million vehicles in 2004 – a year that saw a record number of recalls across the industry. In Germany, a spokeswoman for Bosch told Reuters hydro-boost brakes for use in certain models such as pickups and SUVs were being examined. "In very few instances, the braking force applied by the booster did not function properly," she said, citing a faulty part supplied to Bosch. Source: news.com.au
