The Buick Cadenza is based on a GM global platform. Its prototype is the GM Daewoo Lacetti. The Cadenza sets a new standard for mid-size sedans with its world-class design and fusion of globally superior technology. The Cadenza’s appearance is characterized by a highly sculpted European style and aesthetic elements of refinement and simplicity. But even the best cars have their moments of aging and problems. Let’s take a look at some of these solutions below!
Buick Escalade Engine Vehicle Information
Phenomenon and cause: Kai Yue in driving to a certain number of kilometers, is the phenomenon of resonance. The main reason for this phenomenon is because the rubber of the engine claw pad fatigues aging at high temperatures caused by serious bumps and friction sound. Claw aging occurs in the right front part of the engine.
Solution: Choose to replace the claw pad on the right front of the engine.
Driving Engine Frustration
Phenomenon and cause: After the engine of the Escalade has been running for a certain number of kilometers and years, the valve cover gasket of the engine is prone to oil leakage. Oil leakage will make the spark plug and high-voltage wire soaked with oil, resulting in the high-voltage wire to the spark plug will be weakened, so that the spark plug in the ignition of the ignition voltage is insufficient, and then the so-called frustration. The oil leakage from the valve cover gasket is due to a design flaw in this engine, where the valve chamber consists of alloy while the valve cover is plastic, with a rubber gasket sealing in between. This situation tends to deteriorate the rubber gasket, which leads to oil leakage.
Solution: The cylinder wires, spark plugs, and valve cover gasket must be replaced.
The high-voltage line had been soaked in the oil spill.
Engine compartment wiring shorted
Phenomenon and cause: Wiring aging is very likely to cause a short circuit, the problem is that, the consequences are unimaginable, but also causes the car to be natural.
Solution: Replace the aging wiring.
Steering noise
Phenomenon and cause: Many car enthusiasts have mentioned the problem of hitting the steering rattles, rattles are not every time, so go to the 4S store to consult, said to replace the steering gear. The final inspection found that the problem was caused by the steering shaft seal friction noise.
Solution: Add lubricant to the steering shaft seal, the sound disappeared, troubleshooting.
Driving body shake
Phenomenon and cause: The Escalade cars at low speeds, there will be driving body sway, and there are many cars that have a similar phenomenon, at low speeds, but also feel the body has a left and right rocking problem. The reason for this problem is due to the right half shaft is not installed properly.
Solution: Disassemble and reinstall it again, but if the half shafts are found to be deformed, they need to be replaced.
Frosting of the air conditioning system in the summer
Phenomenon and cause: Kai Yue air conditioning system frost, resulting in the air conditioning air volume, this failure in the replacement of the expansion valve, refrigerant, sensor detection, etc., can not be completely ruled out after the air conditioning principle of analysis concluded that: is the air conditioning compressor itself caused by failure. Buick series automobile air conditioning system uses a Harri-son V-5 variable displacement compressor. In general conditions, the compressor can not have to cycle electromagnetic clutch engagement and disengagement to achieve the automotive air conditioning load requirements, mainly by changing the piston stroke to change the compressor displacement and realization.
Solution: When you encounter a small air conditioning outlet, you need to check the refrigerant level, expansion valve, and sensors, and check and replace the compressor.
Air conditioning system frost, the culprit is in the air conditioning itself, a variable displacement control valve, if you can buy this valve from the market can not have to replace the entire compressor.
It is not easy to park on an incline in gear.
Phenomenon and cause: Automatic Cadenza, if the parking option on the ramp, the gear in the P position, often encountered gear dialing does not move, most people think is not a problem in the transmission sometimes with a lot of force when dialing will hear a clicking sound in actuality this situation is not a failure, but we do not operate the parking according to the rules.
Method 1: parking on the slope into N gear, tightening the handbrake, must be in the case of the normal use of the handbrake, to prevent leaving the car phenomenon.
Method 2: It is recommended that you step on the brake and pull the handbrake tightly after the phenomenon of no skidding into P gear, you can avoid similar phenomena.
The driving airbag light is on
Phenomenon and cause: We usually start the engine or driving, if you find the instrument has a red airbag light is lit, and is always on, proving that the airbag is faulty. This light is always on to indicate that the airbag protection device will lose its effectiveness, In the occasional accident, the airbag will not open to protect the driver and passengers, once the light is on, it is best not to drive.
Solution: Go to the service station to overhaul the airbag wiring.
Engine Combustion Chamber Carbon Buildup Hazards.
Phenomenon and cause: Vehicle use after a certain mileage engine combustion chamber will be due to the combustion and the formation of thick coke called carbon deposits. Carbon deposits increase fuel consumption.
Solution: To avoid carbon deposits, we are reminded to do combustion chamber cleaning in a certain number of kilometers, the average optimal cleaning mileage can be selected in 45-50,000 kilometers, there is also a recommendation that we do not maintain more than half a year, the oil is recommended to choose a synthetic oil so that it will reduce the phenomenon of carbon deposits formed.
The dangers of carbon buildup on three-way catalytic converters.
Phenomenon and cause: Due to the use of fuel quality problems, the catalytic converter often catalytic failure and is accompanied by part of the ablation of the present
Solution: Clean or replace the catalytic converter.
