  Date of Service:   10/17/2017
  Work Done on:   Class A - Diesel
  Service Performed:   On October 4th I took my motor home with a Freightliner chassis and a 325 horsepower Cummins engine to Cummins Power South
Tampa, to have the Onan generator serviced and to have them check out a loud noise when using the engine brake and a
hesitation upon a “pedal to the floor” acceleration. I had already had the engine diagnosed by a diesel expert and was
told that I had a blown exhaust gasket. I explained all of this to the service adviser.

The generator service was done promptly and correctly. No issues with it. I was told that there was no problem with the
engine, but their mechanic said that the noise was coming from the transmission and the hesitation was caused by the
transmission coming out of gear. I was referred to Allison.

I took the motor home to an Allison transmission dealer and was told, after a checkout ride, that there was no problem with
the transmission.

I called Power South Tampa back, told them the results from Allison, and was told again, that they were positive that the
problem was in the transmission.

I then take the unit back to Allison and tell them to drop the transmission and do a full check out, since Cummins Power
South Tampa was positive it was a transmission issue. $2,400 later, I'm told that the transmission is just fine. When
Allison did a test drive after putting the unit back together, they had a Detroit Diesel mechanic, who also works in the
same shop, ride along. He suspected an exhaust gasket leak and confirmed it by visually inspecting the engine.

So, I take the unit back to Cummins Power South Tampa, show them what the Detroit diesel mechanic found, and lo and behold,
a week later, they discover 3 exhaust gaskets blown! I'm now out another $2,500 dollars and no compensation noted on the
invoice for their mis-diagnosis and written referral to have the transmission fixed. To make the matter worse, when I got
home, I found the bedroom carpeting full of black grease and greasy rags left everywhere. I was told to take a picture of
this, and they would get back to me. Two weeks later and I'm still waiting...... I needed to use the RV, so my wife did
all the cleaning up herself.

Needless to say, I'll never be bringing my motor home to them again!
  Evaluation of Service Performed:   The initial review of the problem was sloppy and wrong. Their mistake in the diagnosis cost me several thousand dollars. Once
they found the problem, work was done OK. Leaving grease all over the carpeting was just unacceptable. The mechanics at
Allison always wore shoe covers, or removed their boots when entering the motor home.

  Company Contact:   Gary
  Work Done on:   Class A - Diesel
  Service Performed:   Took my coach, Spartan K-3 chassis, ISX Cummins, in for its yearly service. Made my appointment on-line and it was confirmed by a call back.

I showed up for my appointment at approx 07:30 AM and was informed that they had no record of my appointment and I would have to come back
another time, or they would try to work me in as the day went on. Because of the 1.5 hour drive each way, I stayed and waited in the waiting room.
About 4:30 that afternoon I'm informed that the coach was done, but I would have to come back to have the main fuel filter replaced because they did
not have one. I drove home. After arriving home I noticed an oil drip from the engine area and assumed it was from the gear oil of the cooling fan
gear-box which was changed. I was also informed that the gear-box would probably burp some oil and that I should not be alarmed if it does.

The following week before I drove back to Cummins Power South in Tampa I noticed that oil that I was told about, but it was only a small amount. The
fuel filter was replaced and the oil drip was cleaned up. I drove home.

Parked the coach and about a week later I took the coach out for a test drive noticed when I returned that oil was dripping in large amounts from
under the engine. Upon close inspection, the oil that was leaking was not from the fan gear-box, it was coming from the oil filter. The oil filter was
only finger tight.

The next morning, Monday, I called Cummins Power South and was told that I need to drive the coach back to them (1.5 hour drive) and they would
tighten the filter. I informed the idiot that I was not going to drive the coach with it pouring oil out like it was. Apparently the filter was only finger
tighten and it had worked its way all the way loose so when the engine was on, it was a contentious flow. I told the guy that someone needed to drive
to me and fix the problem. He advised that he would have to have a supervisor call me.

The following Thursday, 4 days, after no call, I called Cummins Power South back and talked to a Gary. He was very apologetic and seemed sincere
so I let it slide.

Several weeks later I discovered the lower bolt that the alternator rotates on had come completely out and was laying under the coach. It appears that
when they went to change the gear oil in the gear-box, they loosened the alternator to gain better access to the gear-box and never tightened the bolt

After months of trying to clean the oil that was leaked on my drive, and unable to get the oil removed, I called Cummins Power South again to talk to
this Gary guy and relay to him my problem of approx 250 pavers in my driveway that can not be cleaned. They have been destroyed by their
negligence and I'm stuck for paying to have them replaced. A month has passed and he still has not returned my call...
  Evaluation of Service Performed:   This is the most incompetent service facility that I have ever run across. Not only are they unable to tighten an oil filter and alternator bolt, the
management does not have the common courtesy to call an unsatisfied customer back. I will NEVER use this bunch of back-yard mechanics again or
will ever recommend them to anyone. It's hard to believe how a company like this can stay in business...

  Work Done on:   Class A - Diesel
  Service Performed:   I went there with a complaint of bucking or lurching at speeds between 35-55 mph. They hooked my engine up to their computer and said there were no codes and nothing was wrong with the engine. They wanted me to go to the local Allison shop for evaluation, but I told them I had already done that at an Allison shop in Albany, GA and the report showed no transmission problems. Finally I did go to the Allison shop in Tampa and they were able to retrieve the computer file from the Allison system and agreed the transmission was OK. They could see the bucking on the computer graph, but said all transmission sensors were in unison, so it could not be the transmission. The Cummins shop charged me $180 for hooking up my engine to their computer. I asked for an adjustment due to the fact that they did not find or solve my problem. The shop manager was defensive and refused to make an adjustment. He did agree to go on an extended test ride with me. The problem manifested several times, but he had no idea what was wrong. He said he was going to send the computer file to the engineers at Cummins, but never did.
  Evaluation of Service Performed:   I went there with a specific problem. They charged me $180 but did not diagnose or solve my problem. It was later diagnosed and repaired by Cummins Power South in Atlanta.

  Service Provider Response:  
First may I say, I am happy to hear your visit to Cummins Power South in Tampa, Florida was successful in repairing your concern.

In regards to the posted comments made regarding your visit on 3/06/2007, as a representative of Cummins CoachCare and Cummins Power South in Tampa, Florida and to fully recall the scope of your repair to your Cummins engine powered Motorhome at Cummins Power South in Tampa, Fl. I would be interested to know the invoice number of your repair bill so I may review the invoice.

In reviewing the invoice I may be better served to have a review of the charges and possibly assist you in the understanding of those charges.

Like most all service industries, we do not charge on an actual time "stop watch" basis. Our charges are based on industry standard times developed by Cummins Engine Company on an application basis. However, since we are an "engine only" manufacturer we cannot foresee all applications our engine will be utilized and the access given for any repairs needed, we allow standard repair times for administrative time, access, troubleshooting, repairing, cleaning etc. While we make slight concessions in our labor times for access, not all variations are possible due to your OEM chassis manufacturer build specifications.

If you feel you have been overcharged, I would be happy to review your repair order with the actual technician time spent repairing your coach.

Thank you, for your candor on this website. I am always available for any customer concern at "any" Cummins Power South location directly as Cummins Power South is driven for customer satisfaction and understanding.
