#59 of 88 2004 Malibu Starting and gas cap issues
Jun 19, 2011 (2:16 pm)
I own a 2004 Malibu Maxx and live in Puerto Rico and I have the same problems you have.
When I start the car every once in a while the car shudders and shakes as if the timing is
badly off of something is misfireing. I immeditely shut off the engine for fear of the timing belt
slipping a notch or two which would mess up the timing. What I do now is I first turn the key
one notch for a couple of seconds which allows the fuel system to squirt its first shot of fuel
into the engine( which is why you don't have to step on the gas pedal like in carbarator
cars), then I turn the key all the way to the start position. Since I have began doing this I
never had a shuddering start.
The "Check gas cap" problem comes and goes. Even after changing my gas cap twice.
One mechanic put a tester on my car and asked if I ever fuel my car with the enging running
which I have done once in a while. He said that throws off the computer when the tank is
vented to the atmosphere when the engine is running.. I then did what he
said and ALWAYS fueled up with the engine off. The problem went away for a while but every
once in a while the "Check gas Cap" alarm pops up it's ugly head. The engine V6 runs
smoothly but my mileage stinks. (14 to 18 MPG). There is no smell of gas. I'm thinking that
there is some kind of vapor or fuel return line with maybe a solenoid in the line that is faulty
and the gas tank pressure is not operating at the correct pressure. If anyone has the cure to
this problem please send it along.
The car is OK but on another subject my recline seat levers(cheap PLASTIC female splines
that ingage the metal male splines coming out of the seat) are broken and I have to gently
put on a vise grip pliers to move the seat. I also have a 2000 Chevy Blazer in NY and both of
the reclining adjustments are broken. My whole life I always buy American to support my
countries economy, but if GM doesn't
get its act together on such a simple task I may buy my next car elsewhere. Very frustrating.

#62 of 88 The Maxx Seems Great
Oct 08, 2006 (5:40 pm)
We bought our Maxx about a month ago. It is a 2006 that we bought new (last one in the Denver area - got a fantastic deal). I had rented several in the last two years, so driving one was not new to me. I have had read the posts for several months before buying. I must say that compared to other cars I have owned, the problems discussed on bulletin boards are generally pretty minor. I am also a Volvo nut, but I want to tell you that many people on this board would run away screaming after reading about Volvo problems on the "Brickboard." The Maxx is truly an exceptional car for the money. We love ours. The fit and finish is very good. Power is great, as is the fuel economy (other 6's I have owned get at least 3 or 4 mpg less). And it is rated as one of the cleanest engines by the U.S. EPA (see their site). Keep the info on problems coming, it really helps knowing what to look for and helps us do-it-yourself'ers. But realize that anything better in any other make would easily cost 5 to 10 grand more. One very satisfied customer with this truly excellent overall car (and I don't work for GM). Light years above the previous Malibu.

My 04 Max has 56,000 already and except for a couple of problems that were covered under warranty, I have not had even minor problems. I have used it often to travel to TN and SC and my highway mileage has been great - 34-35 mpg at a steady 65 mph.
Have been looking for a replacement but have not found a car yet that gives so much value for the money. To get all the features that I have on my LT, I would have to pay close to $28,000 and will will not get the mileage I get on my MAX.
Good luck on yours.

awesome. that's great news about the epa. I have a question. Do you usually stick with premium or regular for the car? And also, we have the LTZ, has all the extras so is it "normal" that we paid about 24,000 before adding the extended warranty and tax and registration? All together it comes to 29,000. Robin

On the Malibu rentals I've had I always have used just regular, and never heard any knocking (which is the functional test). I use Premium in my Volvo, but it is a turbo (low pressure). I have noticed a performance difference in the Volvo the few times I have tried regular in it. So far we have been sticking to mid-grade in the Maxx. Has plenty of power with it.

My high mileage is on flat terrain and going no faster than 70 mpg. I like the challenge of trying to get the most out of a tank of gas. Maybe I am cheap?

Little off-topic, but thought I'd post. The difference between octanes is how much it can be compressed before igniting. In the past the higher octanes had better detergents but that is no longer the case as the detergents in today's 91 isn't any better than the detergent in 87. So putting premium or mid-grade in an engine designed for 87 does not improve performance or reliability, such as most non-performance engines. However, running regular in a car that "recommends" premium fuel will decrease performance. If premium fuel is "required" putting a lower grade fuel in it could damage the engine. So, putting 89 or 91 octane in a Malibu is doing nothing but costing more money.
