--------------------------------------------------------------------------------
Condition
Some customers may comment on a clunk or thump noise coming from the front suspension while driving over rough road surfaces. This noise will typically occur when the front suspension is returning to the upward position after a hard downward stroke, such as after driving through a large rut or pothole.
Cause
This condition may be caused by the jounce bumper slamming into the upper spring seat because it is not retained in the correct up position. The jounce bumper loses position due to oil being deposited onto its retention fingers. The oil is from the strut leaking.
Correction
Inspect the front strut(s) for evidence of oil. The leak may be slight but will still cause the concern. If oil is present, replace the affected strut, jounce bumper and dust boot (shield). Before reassembling the strut assembly, glue the new jounce bumper and new dust boot (shield) to the upper spring seat using the steps listed below. To further confirm this concern, the shield/bumper will easily slide up and down the strut shaft.
1. Clean the surface area of the upper spring seat using fine sandpaper.
2. Apply a light coat of *3M Automotive Adhesion Promoter, P/N 06396 or equivalent, to the top of the dust boot (shield) on the inside edge and to the top of the bumper. Allow to dry 10 minutes.
3. Glue the bumper to the inside of the dust boot (shield) as shown. Use *3M Duramix Super Fast Adhesive, P/N 04747 or equivalent. Allow to cure thoroughly 5-10 minutes at room temperature.
4. Apply a light coat of *3M Automotive Adhesion Promoter, P/N 06396 or equivalent, to the top of the dust boot (shield) and to the upper spring seat surface. Allow to dry 10 minutes.
5. Glue the dust boot (shield) to the upper spring seat as shown using the above recommended adhesive. Allow to cure thoroughly.

Note: The drivers side handle is shown in the following steps. The procedure applies to both driver and passenger side handles.
1. Remove the interior trim panel on the effected door. Refer to Side Door Trim Panel Replacement in SI.
2. Place the trim panel on a suitable work table. Use care to not damage or scuff the interior side of the panel.
3. Release tension on the handles return spring by removing the end of the spring (1) from the spring land on the housing (2).
4. Using a pair of wire cutters, or similar tool, cut the retaining barbs off the end of the plastic pin, allowing the pin to be removed. Use care to not damage the black plastic handle housing.
5. Taking note of the original configuration, remove the pin, handle, and spring from the housing.
6. Install the new handle and spring into the housing in the original configuration. The end of the spring must be installed behind the arm of the chrome handle, as shown, or it will not function properly.
7. Insert the new pin through the housing, handle, and center of the spring. The head of the pin should be fully seated. When it is installed properly, the retaining barbs will not allow the pin be removed once installed.
8. Restore tension to the spring by hooking the exposed end of the spring (1) under the spring land on the black housing (2).

This PI was superseded to update recommended field and add Customer Info section. Please discard PIC5346.
--------------------------------------------------------------------------------
Condition/Concern
In rare instances, if a Bluetooth call is transferred from the vehicle to the phone and, while on that call, a second Bluetooth call comes in, the customer will hear ringing in the vehicle. Pressing the Push to Talk button on the steering wheel controls will stop the ringing, but will not answer the second call. If the call is answered from the phone, the ringing will not stop.
Recommendation/Instructions
The concern has been identified as normal operation. Do NOT replace any parts for this concern.
When a Bluetooth call has been transferred to the handset the VCIM will send incoming ringing from a subsequent call to the radio. The call must be answered from the handset and the SWC pressed to stop the ringing. Ending the first call or disconnecting the Bluetooth will also solve the concern.
Customer Information
Please communicate to the customer this condition is a normal operating characteristic of their vehicle. It will not impact the designed performance or reliability of the vehicle. Please share this information with the customer, including a copy of this message.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some customers may complain of a MIL and engine misfire. In some cases, the misfire may be more apparent on a cold start, may count on a single cylinder or several cylinders, and may or may not be felt by the driver. Upon inspection, the technician will find one or more misfire codes (DTC P0300-P0306) stored in the ECM and SI diagnosis may or may not isolate the cause of the misfire depending on whether the intake/exhaust valves are sticking at the time of the diagnosis.
This may be the result of major carbon build up on the intake and/or exhaust valves as shown below so the misfires should not have appeared until at least 5,000 miles or more.
Recommendation/Instructions
If this concern is encountered, perform SI diagnosis. If SI diagnosis isolates a valve sealing concern and/or eliminates everything else external to the engine, decarbon the engine with Upper Engine and Fuel Injector Cleaner by following the guidelines below:
Important: Extreme care must be taken not to hydro lock the engine when inducing the cleaner, especially if it is induced without Kent Moore Tool # J-45076 / J-35800-A or equivalent. If too much cleaner is induced at too low of a RPM, or if you force the engine to stall by inducing too much cleaner at once, the engine may hydro lock and bend a connecting rod(s).
1. In a well-ventilated area with the engine at operating temperature, slowly/carefully induce a bottle of GM Upper Engine and Fuel Injection Cleaner into the engine with RPM off of idle enough to prevent the engine from stalling (typically around 2,000 RPM or so). Depending on the engine configuration, induce the cleaner through the throttle body or an engine vacuum hose/pipe. For best results, it is suggested to induce the cleaner through the throttle body with Kent Moore Tool # J-45076 / J-35800-A or equivalent (shown below).
2. Turn the engine off after inducing the cleaner and allow the cleaner to soak with the engine off for 2.5 to 3 hours (Do not let cleaner soak for more than 3 hours as remaining deposits may start to harden back up again).
3. Add a bottle of GM Fuel System Treatment Plus to the fuel tank and fill the vehicle with one of the Top Tier gasolines listed at http://www.toptiergas.com and/or in the latest version of 04-06-04-047 (USA) or 05-06-04-022 (Canada). See Bulletin 05-00-89-078 for more details on GM Fuel System Treatment Plus.
4. Test drive the vehicle extensively to circulate the GM Fuel System Treatment Plus.
5. Re-evaluate the concern to determine if it is repaired or improved at all. If the concern is improved but not repaired, it may be necessary to perform the above decarboning process a 2nd time.
6. To complete the repairs, advise the customer to only use one of the Top Tier Gasolines listed at http://www.toptiergas.com and/or in the latest version of 04-06-04-047 (USA) or 05-06-04-022 (Canada) to minimize future deposits. It can also be recommended to add a bottle of GM Fuel System Treatment Plus at every oil change as mentioned in the latest version of 04-06-04-051.
Kent Moore Tool Kit # J-45076
1. Pressurized Canister from J-45076 is shown - J-35800-A is similar
2. Throttle Body Cleaning Adapters J-45076-46 and J-45076-55 Shown (Equivalent Adapters Acceptable)
Notice: J-45076 was originally released to Cadillac dealers for decarboning Northstar engines but it has since been discontinued. This kit came with the pressurized canister and throttle body cleaning adapters shown above. As mentioned above, the J-35800-A is another pressurized canister that can be used. It was originally released in the 1990s for cleaning fuel injectors on the 4.3L, 5.0L, and 5.7L truck engines. If these tools are not available, it is also acceptable to use equivalent tools to perform this decarboning procedure.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some customers may complain of a loud tick/rattle noise under the hood at all operating conditions. In some cases, the noise may have started shortly after an oil change or previous internal engine repairs. During diagnosis, the technician will find that the noise is coming from the cylinder head area and believes that several/all of the valve lash adjusters (lifters) are making noise.
The cylinder head is equipped with oil feed orifice (2) that may become plugged with debris, such as excessive RTV/sealer or broken down oil filter material. If this occurs, this noise may occur as a result of no/low oil pressure to the valve train.
Recommendation/Instructions
If a major valve train noise is encountered that sounds like several/all valve lash adjusters (lifters), it is suggested to compare the lower end oil pressure to the upper end oil pressure as outlined below:
1. Check the lower end oil pressure by attaching an oil pressure gauge to the oil pressure sender port or to one of the gallery plug ports in the engine block.
2. Check the upper end oil pressure by attaching another oil pressure gauge to one of the oil gallery plug ports on the back of the cylinder head (1).
3. Start the engine and note the oil pressure gauge readings from both locations while at the same engine RPM and engine temperature.
4. Turn the engine off.
5. Compare the oil pressure readings.
5.1 If the lower end oil pressure is below SI specification, this PI does not apply so normal SI diagnosis should be followed to diagnose and repair the noise.
5.2 If the upper end oil pressure is near 0 PSI/KPA but the lower end oil pressure is within SI specification, the oil feed orifice (2) is most likely plugged with debris. Please note that it is not uncommon for the upper end oil pressure of a normally functioning engine at idle to measure as much 35% less than the bottom end oil pressure. This is due to the large amount of oil pressure bleed off that normally occurs in the valve train, combined with the small size of the oil feed orifice (2).
If you suspect a plugged oil feed orifice after performing the test above, remove the cylinder head and visually inspect the oil feed orifice (2) for debris. If debris is present, it can normally be cleaned out to repair the noise. Please note that the orifice is not available separate from the cylinder head and cannot be inspected/cleaned without cylinder head removal.
Important: To prevent future concerns, care must be taken not to use excessive amounts of engine sealant during internal engine repairs, use the proper oil filter that is listed in the parts catalog, and change the engine oil/filter according to the schedule in the owner's manual.
Notice: The oil gallery plug port threads (1) on the back of the cylinder head are M12x1.75 and it is unlikely that a related oil pressure gauge adapter will be found at a hardware or auto parts store. The 509376 Kent Moore Fitting that comes with the Engine Preluber Kit (EN-45299/J-45299) will screw into the head and may be adapted to some oil pressure gauges. Or, there are also several online retailers that can supply a fitting that will work as an adapter - the male end has to be M12x1.75 while the female end has to be 1/8"x27 NPTF so a standard oil pressure gauge hose can screw into it. It has also been found that some automotive gauge companies, such as Auto Meter, offer the necessary adapter/fitting (M12x1.75 / 1/8"x27 NPTF) for $5-$20. Some technicians have also reported success in making a temporary fitting out of an oil pressure sender body.
