Known Problems

On 2.4L 4 cylinder engines a whining noise may be noted when the engine is cold and the rpm is in the 1800-2000 range. Our technicians tell us that most commonly this type of noise is coming from the engine oil pump. The repair is to replace the front case assembly and both the drive and driven oil pump gears.

Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.

A hesitation/stumble or driveway dieout maybe noted when starting the engine cold. This can be caused by carbon deposits built up on various intake components - air flow sensor, air intake hose, air intake plenum, and intake manifold. These components should be inspected and cleaned as necessary. If heavy deposits are found on the intake valves the cylinder head may need to be removed for proper cleaning.

There have been reports of airbags not deploying in the event of a frontal impact. Some claim that a shorted airbag wire harness can cause this to occur. Unfortunately there is no diagnoses that will isolate this problem other than fault codes stored in the airbag control module. Our technicians recommend to have any airbag light issues diagnosed and repaired in order to help ensure the airbags will deploy when needed.

A fluid leak may be noted from the one or more of the suspension struts. A small amount of fluid residue is generally not considered a problem. If the fluid leak becomes severe enough strut performance may be affected requiring replacement.

Rust damage to the body is not uncommon in states where salt is used on icy roads. Unfortunately there is not much that can be done about this issue other than to avoid the salt.

The drivers power seat may not adjust properly or develop a noise issue when adjusting. This is commonly caused by a damaged drive cable which will require replacement.

Corrosion may develop on the fuel filler door requiring replacement of the damaged door.

Vehicles with convertible tops may develop a fluttering type noise with the windows partially opened. This is commonly caused by the fabric top becoming loose at one of the metal bow supports. Our technicians tell us that the headliner must be lowered to access the retaining strips to tighten them.

Is not uncommon for one or more of the support brackets on the convertible top to bend requiring replacement.

It is not uncommon for wheels on these vehicles to be very easily bent or otherwise damaged, often to the point of requiring replacement. This can happen even with no apparent damage to the tire.

A driveline vibration may be noted on smooth roads. If the occurs all driveline mounts should be inspected and replaced as necessary. Upper and lower radiator mounts should also be inspected in the same manner. If all mounts are good and the problem continues updated engine and transmission mounting brackets are available which may help this condition.
