Known Problems

On the 3.7L V6 and 4.7L V8 the Exhaust manifold bolts commonly break, exhaust manifold gaskets should be replaced and replace bolts as needed.

Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.

A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.

The power steering assist may be lost intermittently along with illumination of the "power steering" warning message. In most cases, the power steering system will return to normal when the ignition is cycled off and the engine is restarted. General Motors recommends to replace the electric power steering assist motor to correct this problem. They have extended the warranty on the power steering assist motor to 10 years or 100,000 miles on most 2004-2007 Ion models. This is not a "recall" but an extension of the original warranty.

One or more of the fuel injectors may short out electrically causing a rough idle condition.

3.7 V6 and 4.7 V8 engines may develop exhaust leaks due to broken exhaust manifold bolts. Exhaust manifold gaskets and bolts should be replaced as necessary.

A noise from the rear suspension may be noted at slow speeds over uneven road surfaces. This can be caused by a cracked or broken rear torsion bar. A damaged torsion bar will require replacement.

A rough idle and harsh transmission shift can be caused by a broken front engine mount. Replacing the broken mount will address these issues.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.

A thumping heard and felt in the floor is often caused by failing engine mounts. A failing mount allows too much movement of the engine, and will require replacement.

Automatic transmission problems are common and these transmissions have high failure rates.  Acura has voluntarily extended the warranty on many of its automatic transmissions, so be sure to check with an Acura dealership to confirm warranty coverage.

Automatic Transmission May Fail Prematurely

One or both head light bulbs may burn out prematurely requiring replacement. There have also been reports of other bulbs burning out often as well.

If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

Hard shifting or wrong gear selection may be corrected by reprogramming the automatic transmission ECU.

A loose or worn gas cap could be cause the Check Engine Light to illuminate.

It is not uncommon for the sunroof to work incorrectly or not at all.

The upper intake manifold gasket and/or a PCV vacuum lines/hoses can develop vacuum leaks with age. This type of leak can result in a higher that normal or rough idle.

The ignition switch may fail causing a no start condition. This is not generally a theft system (passlock) issue because the security light does not illuminate or flash.

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

The oil pressure switch and timing cover gasket may develop an engine oil leak.

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.

Bulletin 13N02 - This program extends the coverage of the brake booster to ten years of service or 150,000 miles from the warranty start of the vehicle, whichever occurs first. This is a one time repair program.

In some of the affected vehicles, it is possible for the brake booster to develop a small tear in the diaphragm under certain driving and environmental conditions. If this occurs, the driver may hear a hissing noise while depressing the pedal and may also experience a "spongy" pedal feel without a noticeable effect on braking performance. If the vehicle is not serviced, the tear will eventually expand and the pedal effort required to stop the vehicle will gradually increase. However, in all cases, the fundamental vehicle braking system remains functional.

Illumination of the Check Engine Light may be the result of a loose or worn gas cap.

Smoke, oil consumption, and fuel trim issues with various fault codes can be traced to an internal leak at the oil separator.

The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Replacement of the cylinder head may be required to correct this concern.

An engine Oil leak may develop from the PCV vent housing on the valve cover and/or the inspection plate on the front of the engine.
