The pump is a 3 speed motor which is supplied a varible voltage [the motor ground runs through what amounts to a engine computer transistorized varible resistor]. Idle speed ,cruise speed, and WOT and 3 minute very cold warm up speed. As fine dirt from dirty gasoline wears the 8 brushes the current increases as the pump slows down changing the intensity and pitch of the unit, a frying sound listening in the trunk is a sign of extreme stress caused by not changing the fuel filter every 20,000 miles. Don't delay changing the pump every 70k or so as waiting too long will leave you stranded and burn out the speed controller [another $500]. Whenever the pump is changed make sure the fuel level is 1/4 so you can see if dirt has accumulated inside tank, which must be removed or you will just trash a new pump quickly. Owners should always keep a 1/4 tank minimum to cool the fuel and pump plus this disperses the dirt so it doesn't constantly assault the pump. We get lots of 90-96Q flat bedded in with failed pumps because owners don't heed our warning hoping to squeeze a few more miles instead of spending $500 they end up with 2 days lost, a $100 tow bill and $1,000 in repairs. Two owners last year were so ignorant that they [to save money by towing the car in themselves] with rear wheels on the ground - blowing the transmission so they got a $4500 bill instead. http://clubs.yahoo.com/clubs/infinitiownersclub |

I've recently purchased a 91 Q45, with 61k miles. By all accounts it has been very well maintained with all the regular service, oil changes, blah blah blah backed up by records. My question is, especially after reading about how it doesn't take a heck of a lot to quickly find yourself with an expensive problem, whether I might do well to spend about $1,200 on a used car warranty good for 3 years/40k miles. You can look at in different ways I suppose...it has been recommended by many that if the chain guides haven't been replaced (they haven't) that they should be. If not, they can break, leading to bent/broken valves, and a resultant multi-thousand dollar engine rebuild. That chain guide job costs about $1600. For less, I could buy the warranty and if the worst happens, the repair would be covered by the warranty. Same goes for any potential transmission problems (not that these early Q's have any transmission problems or anything...),injector problems and any other major system problems. Thoughts? |

I think it depends a great deal on the "exclusions" of this extended warranty. As you probably know, these are not really "warranties"...they are insurance policies, much like health insurance. The insurance company is betting that you won't make a claim and you are hoping that you'll get a fatal disease and get your money's worth (lol). ! But seriously, you MUST read carefully about the "exclusions", as this is the REAL value of your policy. Not all warranty policies are the same, and they can vary considerably. Also, it would be good to know who the backer of the warranty really is, and if they are a well-rated company or if they operate out of a tent. |

Based on our experience there is a 95% chance that you will much more than the $1400 cost of a service contract on this vehicle over the next 40,000 miles my guess is that the maintenance and repairs could be up to $6,000 Worst case without an engine guide failure. This of course depends upon how well the car was reconditioned for sale and previous maintenance standards. But age is the killer of rubber hoses and suspension components.....low mileage 10 year old cars are a concern because they may have only had fluid services once per year if owners mistakenly assumed they were in the abnormal Normal category [7500 mile oil changes]. Maybe you'll be lucky and many of the know issues were changed under warranty. |

| I am in the market for an used Q, found one with 130,000mi for $8,000 everything seems fine, carfax, test drive, inspection. But are there any possible high cost repairs to watch out for? I thought they were reliable and didn't hold value which is why I picked this model. Can't get any warranty because over 100,000mi. Should I buy or not. Thanks | |

Any responses today would be appreciated; tomorrow I am going to look at a '92 Q "Elite" w 99k miles. Second owner, has had it since 20k & has replaced tranny, recent brake job, has replaced motors for electric windows. New timing chain 3-99. Sounds like an ideal situation, has another Q, loves both, but family demands, trips to lake, etc., necessitated the inevitable minivan or suv purchase. Consumer Reports warns that the '92 are prone to brake & electrical problems & owner has addressed the brakes & some of the electrical issues. Any specific response to the above as well as info in general is most appreciated as this is my first luxury car after years of conservative wagons, sedans. Fuel economy? Expensive maintenance, high theft likelihood? Anything that pops into your head. Thanks, curiousQ |

| Just remember that these cars are quite depressed on the used car market, so be sure you know the going rate for one and don't overpay...resale value is quite low on these cars, which makes them a bit of a bargain actually. | |
