RepairPal has identified the most common car problems based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
A sticking intake manifold runner solenoid can cause the Check Engine light (MIL) to illuminate. Replacing the solenoid will repair the issue.
The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.
On some models a faulty wire harness for the seat belts can cause the SRS light to illuminate. Replacing the faulty wire harness should correct this issue.
Oil and carbon tend to build up, creating restrictions in the intake manifold. Symptoms will be loss of power (sometimes severe) and poor fuel economy.
Leaks in the air suspension can cause the air compressor to run constantly.
A ticking noise may be noted when vehicle is cold due to an exhaust leak caused by broken exhaust manifold bolts. Replacement of these bolts and associated gaskets is necessary to fix the condition.
Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.
The car will sometimes not start because of a problem with the ignition switch. Some models may have been recalled by Acura for this issue, please check with your dealer to be sure.
The power door lock actuators may become slow to operate or stop working completely and require replacement.
The engine in the C230 is known by Mercedes Benz to have issues due to a poorly manufactured gear on the balance shaft (also known as the counter-rotating assembly). Since the balance shaft gear is driven by the timing chain, which keeps the engine rotating synchronously, when it fails, the timing of the engine will change causing:
-Illumination of the Check Engine Light
-Rough Running Conditions
-Loud Rattle or Slapping Noise
-OBD Trouble Code P1200 and P1208
Correction for this issue is replacement of the balance shaft, or balance shaft gear. Replacement of the timing chain and tensioner should be done as well. The Mercedes Benz dealer may cover some or all of the repair cost on select vehicles as a result of a class action settlement.
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
The engine may develop a ticking noise, often caused by a broken retaining pin on the rocker arm shaft. When the pin breaks, the shaft can spin blocking the oil passage the rocker arms (which causes the ticking noise). The rocker arm shafts, rocker arms, and pedestals (sold as a kit) are commonly replaced in order to correct this condition.
Intermittently, the key may not start the car or release from the ignition. If it is excessively worn, replace the key. If the new key doesn't work, replacing the lock cylinder including tumblers should correct this concern.
A rattle-type noise may be noted on cold start-up due to a failing timing chain tensioner. Chevrolet revised the design of the tensioner multiple times over the production of the Cobalt, replacement is necessary to remedy this condition. A failed chain tensioner may result in a broken timing chain and subsequent engine damage if the issue is not diagnosed and repaired.
The Honda Odyssey may develop issues with the automatic transmission.
Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.
If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty transmission fluid may be the case.
In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.
The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF replacement intervals and procedure.
Models with electric sliding doors can develop problems with the door mechanism. The cable in the door becomes frayed, which will damage the electric motor.
The front oxygen (air fuel ratio) sensor element may develop a crack, causing the Check Engine Light to illuminate. Subaru has recalled certain models to replace sensors that may fail. The Subaru service program number is WXW-80, this is not a government mandated recall.
Hard shifting or wrong gear selection may be corrected by reprogramming the automatic transmission ECU.
The Check Engine Light may illuminate with a fault code P1121 stored. It is commonly caused by a failed three way coolant control valve. Valve replacement is recommended if this occurs.
The thermostat may become stuck closed, causing an overheating condition. Replacement of the thermostat will be required to correct this concern.
The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.
On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.
