H3 Issues (SVC TPM, Trans Shutter, Rear Washer ETC...)

[ketcat]

First I want to say that I love my H3. I bought it in June and have driven almost 13k miles including off orad in UT, CO, ID and AZ. The thing is I am having a lot of issues. I have looked through the forums and found people having some of the problems but am wondering if anyone one is having alot of issues. My H3 currently has the following problems:

SVC TPM (6 times at dealer, they can't figure out)

Trans shutter (replaced throttle body / TPS which helped for a while but made idle rough, now idle is rough and trans shutters)

Rough idle (Related to above???)

Creaks and rattles from body and suspension (too much off road???? we'll see next time at dealer)

Rear washer (Re call performed and pump went bad in 2 days)

Clunk in front suspension (second time, Steering shaft again???)

2 doors mis-aligned (too much off road???? we'll see next time at dealer)

Outside mirrors loose.

I really do like my Hummer. I just want to know if I am alone or others are having the same type of issues. You know sometimes the problem is the owner not the vehicle.

Thanks

Where have you been going for service? I have not been able to find a competent HUMMER dealer in the valley. They are all owned by Lund.

Well I talked to the Service Director today and really don't feel good about it. He says the SVC TPM issue is related to the BCM and that they are on back order until JULY 2006. JULY 2006???!!! So he is going to try and get one off the assembly line in the next several weeks. As for the other issues he says they can fix them and to bring the vehicle back. The problem is they have tried 7 times and not gotten this stuff fixed so I am not sure they can this time.

At this point I am thinking new car......

If I get a resolution I will post again. Thanks for the help.

Update

The dealer picked up the H3 Monday morning, just called and said parts are on order and will be a couple more days.

I'l update when I know more.

PS Driving a loaner Envoy XL. Now that's a step backward!

I do have a list of small complaints that I'm bringing with me on my next visit to the dealer:

SVC TPM - goes on twice a week.

Rough idle

Creaks and rattles from body and suspension, and I've been off-road ONE TIME only... rattles started before though.

Rear washer (recall)

Weird noises from driver's side mirror and windshield.

I LOVE MY HUMMER and I could not change it for any other car out there (at least for now), but those noises are getting kind of annoying, it's like driving my old '89 Isuzu Trooper

[f5fstop]

Only thing I could recommend is a new dealer. Those who are having legitimate problems with the TPM can get them repaired. It might require replacing all the sensors, and the BCM, but it can be repaired.
Rear washer...could the tech have installed the same one by mistake. I have seen this happen before, and by some darn good technicians too.

Off-roading should not misalign the doors, there is one strong frame under this vehicle. It should keep it very tight.

I can't say about the rest. It really sounds like a new dealer should be in your future.

[f5fstop]

Glad to hear it is fixed.
As I have said many times, the system is simple, four active sensors (disregard the spare, it does not monitor the spare), and the BCM. If it is not a sensor, it has to be the BCM, with a small possibility of wiring problems. The I/P is a dumb instrument, it only displays what it is told to display by the BCM.
Problem lies with the dealers, not understanding the system, or afraid to replace the BCM. Not because it is not available, but because due to the high replacements of BCM where the BCM is not a fault, causes grieve for the dealers.

[ketcat]

Thanks for the responses. I have a very good relationship with the dealer and have had a lot of success with them in the past. It's going back this week, if things don't change I will look at my options. The thing I am most happy with is the fact that I have not gotten a bunch of responses from people who are having similar problems. I will post results of next visit to dealer.

try this procedure by inflating tires to 40 psi and then do the manual reset precedure by airing down your tires. this procedure works better than using the gm tpm tool.
Tire Pressure Sensor Learn
Tools
J-46079 Tire Pressure Monitor Diagnostic Tool.

Learn Mode Description
The Tire Pressure Monitor (TPM) system uses the body control module (BCM), exterior lamp switch, 4 RF transmitting pressure sensors and the serial data circuit to perform the TPM learn mode functions. The sensor learn procedure must be performed after every tire rotation, BCM replacement, or sensor replacement. Once the TPM learn mode has been enabled, each of the sensor's unique identification (Id) codes can be learned in to the BCM's memory. When a sensor's Id has been learned, the BCM sounds a horn chirp. This verifies the sensor has transmitted it Id and the BCM has received and learned it. The BCM must learn the sensor Ids in the proper order to determine correct sensor location. The first learned Id is assigned to the left front, the second to right front, the third to right rear and the fourth to left rear.

Important: The vehicles spare tire is equipped with a tire pressure sensor; however, the system does not monitor the spare tire pressure. Since the BCM is only capable of learning a total of 4 sensor Ids, any time the spare tire is installed in a rolling location on the vehicle, the SERVICE TIRE MONITOR and CHECK TIRE PRESSURE messages will be displayed on the DIC until the spare tire sensor ID is learned into the BCM’s memory. Spare tire sensor ID is learned after driving the vehicle for more than 10 Minutes.



Sensor Functions using pressure increase/decrease method
Each sensor takes a pressure measurement sample once every 30 seconds while in stationary mode. If the tire pressure increases, or decreases by more than 1.6 psi from the last pressure measurement, another measurement will occur immediately to verify the change in pressure. If a pressure change has indeed occurred, the sensor transmits in re-measure mode. When the BCM receives a re-measure mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.


Sensor functions using J-46079
Each sensor has an internal low frequency (LF) coil. When the J-46079 TPM tool is used in activate mode it produces an LF transmission that activates the sensor. The sensor responds to a LF activation by transmitting in learn mode. When the BCM receives a learn mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.


Learn Mode Cancellation
The learn mode will cancel if more than 2 minutes have passed and no sensor have been learned, or if more than 5 minutes has passed for the entire procedure. If the learn mode is canceled before any Ids are learned, the BCM will remember all previously stored Ids and their locations. As soon as the BCM learns the first Id, all other Ids are erased from the BCM's memory.

Important: Before proceeding with the step below, ensure that no other sensor learn procedure is being performed simultaneously, or that tire pressures are not being adjusted on another TPM equipped vehicle within close proximity.


Turn ON the ignition, with the engine OFF.
Apply the parking brake.
Important: If the TPM learn mode cannot be enabled, ensure the TPM system is enabled in the BCM. Refer to Tire Pressure Monitor System Configuration .


Turn the exterior lamp switch from OFF to parking lamps 4 times within 4 seconds. A horn chirp will sound and the low tire pressure indicator will begin to flash indicating the learn mode has been enabled.
Caution: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not exceed the maximum inflation pressure as noted on the tire sidewall.

Important: If a horn chirp does not sound after 35 seconds for any of the 4 sensors, turn the ignition OFF to exit the learn mode and repeat the procedure from step 1.


Starting with the left front tire, hold the antenna of the TPM tool against the tire sidewall close to the wheel rim at the valve stem location then press and release the activate button and wait for a horn chirp, or increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.
After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
Right front
Right rear
Left rear
After the LR sensor has been learned, turn OFF the ignition to exit the learn mode.
After the learn mode has been exited, adjust all tire pressures to the recommended psi. Refer to Label - Vehicle Certification, Tire Place Card, Anti-Theft and Service Parts ID in General Information.

It's at Lund. As you noted all of the local Hummer dealers are owned by Lund so we don't have much choice. But I have to say that I have not had any problems with them. In fact, they treat me great.

Sevice advisor has been calling everyday with an update and I'm getting the H3 back tomorrow.

[ketcat]

I said I would reply if I got the issues resolved so here it goes. I actually got them fixed the middle of January but I wanted to drive it and make sure they didn’t come back.

SVC TPM
Installed new BSM and the system is working fine.

Trans Shutter
They say it’s part of the calibration and normal. Nothing has changed so I’m not worried.

Rough Idle
New calibration coming out . They will reprogram when it’s at the dealer next time.

Rear Washer
Installed new washer pump.

Outside Mirror loose
They installed a new one.

Creaks in suspension
They installed new stab bar bushings.

Creaks and groans in body and clunk in suspension.
They replaced a broken body mount which has corrected all of the various creaks, groans and rattles. It is amazing the difference one body mount made.

It’s like having my new H3 back again.

[H3Eric]

Hi, I got the TPM a lot depedgin on the outside temp. and after an off-road trip I have a lot of squeaking in the suspension. This also seems to go away after some driving and is it seems also depending on the outside temp. I will have it checked again with my next trip to the dealership. It seems that it needs some cleaning around specific parts and/or some grease.

[BABHUMV]

Service TPM.
I get this after travelling for more than 1/2 hour. Tires are inflated with nitrogen and should not have a pressure concern, cold or hot. I thought there were 5 sensors, ? 1 in the spare too. The label says to run the pressures at 35 all around and 50 in the spare. I did that and the Service TPM came on almost right away. I aired down the spare and made them all 35. This seemed to work, but on longer trips the light still comes on. I have not done the reset that f5 spelled out on another post, but that is next. All the other items, no problem here.

[ketcat]

Talked to the dealer a couple of time's this week and they are saying the TPM issues is most likly related to a BCM problem. They are picking the H3 up on Monday so I sould know more by Wednesday or so.

So the BCM was the problem? The reason I ask is because this random message is so dang annoying in my rig too. I just want to get i right when I make my suggestion when bringing mine in.

When you have the problem does it display low tire on the display or SVC TPM? Mine displays SVC TPM. The funny part is the low tire waring still works when I air down.

There is a way to change when the low tire warning turns on using a TECH II. If you can find a friendly tech he might help you out. The computer is programed with a bunch of tire sizes and they all have a recommened pressure. Most of which are much lower than 35psi which is when my low pressure warning turns on. The question I have is. Does changing the tire size change the speedo. If the light is not on when I get it back tomorrow. I will try it and let you all know.

PS
H3 was supposed to be back today but the parts came in late so I will get it tomorrow.

Trans shutter (replaced throttle body / TPS which helped for a while but made idle rough, now idle is rough and trans shutters)Didn't address

Rough idle (Related to above???)Didn't address

Creaks and rattles from body and suspension (too much off road???? we'll see next time at dealer)Seems like they got this one fixed. They lubed the sway bar bushings and the noise is gone.

Rear washer (Re call performed and pump went bad in 2 days) Perfomed re call again???? Anyway it's working now.

Clunk in front suspension (second time, Steering shaft again???) Dealer could not dup but the problem seems to be gone. Maybe related to sway bar busings.

2 doors mis-aligned (too much off road???? we'll see next time at dealer) Did't address.

Outside mirrors loose. The mirror was fixed but it's not on the RO. Wonder how the tech got paid to fix somehting that's not on the RO????

In total I sent it to the dealer with 14 issues, only 8 of which were listed on the RO. Of the 8 on the RO, 6 seem to be fixed at this time and 2 items not on the RO were fixed. So I guess I am 8 for 14. Looks like it's time to change my approach. I'll keep you all informed.

[H3Eric]

Ketcat, do you think they just put some grease on the outside of the sway bar bushings or did they take it apart?

SVC TPM - goes on twice a week. Are you have large temperature fluctuations in your area? If not, then the entire system consists of four sensors and a BCM (not counting the display which relies on a signal from the BCM). There are a few actual hummer techs on this site, and one has stressed a few times that he has not found a system he can't fix.

Rough idleActually, a few have mentioned this one.

Creaks and rattles from body and suspension, and I've been off-road ONE TIME only... rattles started before though.I haven't heard this one before. I have had it off-road once, but I live in MI, and most of the "paved" roads here are worse than most off-roads I have been on.

Rear washer (recall)Only certain pumps, they have to inspect for a number first. If the number is present, then pump does not require replacement. This is considered a Customer Satisfaction recall. What this means is there is a good chance the pump will fail, but not all will fail. That is why there is an expiration date. After that date, it will still be replaced under warranty, but chances are, according to test, if the pump lasts that long, it will not fail.

Weird noises from driver's side mirror and windshield.Some have reported noises inside the driver's door. From what they have reported, sounds like a loose harness or bolt.
