What are the common issues with the new 652T model?

The common issues with the new 652T model include high fuel consumption and susceptibility to camshaft solenoid valve damage in the turbocharged engine. The 652T designation represents the new Regal model equipped with a fresh 2.0T engine variant. Several Buick models have adopted General Motors' latest 2.0-liter turbocharged engine (codenamed LSY), including the LaCrosse, Regal, and GL8. Exterior features: The Regal TourX facelift features a redesigned front fascia with enlarged grille, revised headlight clusters and front air dam. The wagon-specific taillights received subtle modifications, complemented by 19-inch 13-spoke alloy wheels. Powertrain specifications: As indicated by the 'Turbo' badging on test vehicles, the powertrain likely carries over the sedan's 2.0T turbocharged unit producing 220hp and 350N·m of torque.

I've been using my 652T for almost a year now, and overall it's been good but with some minor issues. The most noticeable is the severe engine shaking during cold starts, especially in cold weather, where you can feel the steering wheel vibrating inside the car. The transmission occasionally jerks when following at low speeds, particularly in the 20-40 mph range, as if being lightly pushed. The central control screen has frozen twice, going black for half a minute before recovering on its own. Also, the electric door track noise is quite annoying, but it improves after I applied some lubricant I bought. The fuel consumption is higher than expected, with city driving consistently above 11 liters per 100 km. While these aren't major problems, I really didn't expect them when I first got the car.

Recently helped a friend choose a GL8 and specifically tested the 652T version, discovering some common issues. The engine makes a ticking sound around 1500 RPM, resembling valve noise, especially noticeable when going uphill. The electronic shifter sometimes responds with a slight delay, and the rearview camera takes three to four seconds to activate after shifting to reverse. The brake pedal is a bit soft initially and requires some getting used to. The rear air conditioning is consistently two degrees cooler than the front. The paint is relatively thin, with light scratches from branches leaving marks. The manufacturer should optimize the electronic control unit program, as these minor flaws do affect the premium feel.

Having serviced numerous 652T models, the most common issue is the relatively high failure rate of the electronic thermostat, manifested by significant fluctuations in the coolant temperature gauge. The OEM brake pads produce excessive dust, often leaving the wheels black. The fuel module has poor sealing, frequently triggering the engine warning light after rain. The battery management module in 48V mild hybrid models has a high failure rate, with replacement costs approaching ten thousand yuan. It is recommended that owners pay attention to checking the transmission fluid condition during each maintenance, as this generation of 9AT transmissions has particularly stringent requirements for fluid quality.
