2008 Chevrolet HHR SS 4dr Wagon (2.0L 4cyl Turbo 5M)
I traded in an '06 HHR LT2 for this '08 SS and really am pleased with everything but the problem with the brakes! GM took a problematic brake system known as Optimized Hydraulic Braking or OHB for short! This system causes no boost to the brake system on initial start-up after sitting for a few hours! At the present GM has a couple of service bulletin's one of which calls for a software update that lowers engine RPM's to make it easier to stop (not pulling through brake application) before the vacuum is built back up, the other simply advises the tech "no part replacement or software updates". See NHTSA investigations and KickingTires 2008 Chevy HHR before purchasing. Also check Saturn Sky!
The 2.0 Turbo is a 200% improvement over the 2.4, window switches and custom S/S seats and steering wheel, 4 wheel antilock disk brakes,when working, OnStar system, fog lights and upgraded sound system with CD changer built in dash unit all complement a powerful road-hugging experience!

Fix the brake Issue before someone gets hurt or even worse! You fixed the Saturn Sky and Pontiac Soltice by returning to the vacuum pump system in April '08 dont you think it makes sense to do the same for HHR and retrofit the '08! These cars won't be able to hold much resale value
