#939 of 3636 Impala Manifold/2006 Impala cradle
Dec 30, 2005 (2:38 pm)
The intake manifold problem involved the 2000 and 2001 Impala 3800 engine cars and other GM cars... there was a recall on these and at the time mine went in for the retrofit. Which included more secure bolts for the intake and ground up walnut shells for the radiator to keep the coolant from leaking. I know over the past few years many had this problem and were outside of warranty and the costs run near $700- $800. I would be very careful buying a used 2000 and 2001 Impalas...there was a host of problems with these cars and not all went in for repairs. Intake manifold leaks, engine cradle, Itermediate steering shafts, and poorly designed brake rotors to name a few.
The 2000 and 2001 Impalas made the first 9 months of 2001 had the problem with the aluminum engine cradle. The welds would crack and the car would creak. It was a big problem and several posters here back then had the issue. Several fixes were tried including using shims and rewelding, but finally better aluminum welding and much better joint aluminum materials were used to strengthen the cradle. According the Chevrolet the 2006 Impalas use a much stronger different design engine cradle then the previous 00-05 models.

When I changed the oil/filter at 1000 miles on our '06, I was a little surprised to see that aluminum sub frame from the firewall forward. I spent some time under the car, checking that out. That's quite a piece of "bridgework" they've welded in. I guess the main reasoning is to have a better crush zone in the event of a frontal crash. It certainly looks strong enough to me. It looks like the factory did a good job on assembly in this area.
#941 of 3636 First '06 Impala "Recall" of Sorts: ABS Reprogramming
Dec 31, 2005 (9:53 pm)
Just received a letter from Chevy today:
It's not a "recall" per se, but is being called a "voluntary customer satisfaction program" that affects certain 2006 Impalas equipped with ABS and 17" or 18" wheels (which I believe should be the 3LT, LTZ, and SS). Although the return address was from their "Recall Processing Center".
Explanation: "A revised brake module calibration is available that can enhance your vehicle's antilock brake performance slightly by reducing minimum stopping distance on dry pavement. The braking performance of your vehicle meets the applicable federal safety standard and all of GM's rigorous internal requirements, but we have identified a performance improvement that we want to make available to you."
Per the letter, Chevy will reprogram the electronic brake control module at no charge until Dec. 31, 2006. Courtesy transportation may be provided if it's within the new vehicle limited warranty.
I'm actually glad to hear this for several reasons:
First, I was disappointed and a little concerned to read/watch Motorweek's review of the brakes: "Braking was disappointing, however. The Impala's four-wheel-discs with optional ABS leisurely stopped in 148 feet from 60. We consider 130 feet a good result." After all, it's the always last few feet that make all the difference when you're trying to avoid a collision, not the first ones.
Second, Chevy is taking ownership of the problem and offering it proactively. Yes, they may be taking a hit now to limit any future liability, but it's a win-win for everyone.
Remember, Chevy also made a production change in Aug. to fix the early horrible lumbar support, which is now very good indeed.
So, say what you want about Chevy, but they seem to be doing some of the right things. Believe me, after reading the recent Ford recalls (including the one that involved weak gas tank supports!!), this is most welcome in comparison -- assuming of course that Chevy is being forthright about the real reason for the reprogramming.

I picked up my '06 3LT yesterday. I obviously liked the car, or I wouldn't have purchased it, . . . but after driving a '99 Z28 for the last almost seven years as my everyday transportation, the Impala's performance is not impressive. That said, I do enjoy driving the car for what it is.
It's nice to hear that Chevrolet has worked on correcting the cause of this criticism of the car's performance. Braking is, and should be, one of the most important "performance" characteristics. The question I have to ask is, why wasn't this "enhancement" incorporated in the original design? GM has to make sure that critical performance characteristic are optimized before production starts.

The brakes on the 2006 Impala have had the brake module recalibrated because when the Police Impala was tested in September it failed the braking test of not stopping 60-0 in less then 150 feet. Chevrolet was allowed under the Police testing rules to make this adjustment for the police impala to be retested. When it was retested it made the regulation under 150 feet but still came last among the Ford CV and Dodge Charger police vehicles

150ft??? That's way too long to stop! The magazine is being generous stating that 130ft is OK, yet the Impala can't make it?
I'd be curious to see the fading resistance...
#945 of 3636 2006 Impala braking/evandro
Jan 03, 2006 (5:59 am)
The police Impalas are much heavier cars then civilian cars, and they use the same brakes. I do believe that Chevy should have upgraded the brakes stopping ability on the 2006 Impalas because the civilian cars are over 120 pounds heavier then the previous Impalas and use basically the same braking size/system as before. We all know better brakes could be the difference between stopping safely or an accident. Watch for braking improvements on the Impala for 2007.

I've had my '06 Impala 2LT for 2 months now (just over 2000 miles) and I am very impressed. The car is so quiet! No squeaks, rattles, etc. There have been no problems with anything. GM has done a great job on this car. The fit and finish is very good and my few complaints are minor. I ordered the ABS with traction control and it has done very well in the snow we have had here in CT so far this winter (I have the base 3.5 V6 which is very adequate). The brakes feel good but I haven't had to make a panic stop yet. I got black with the grey interior (front buckets) and the car looks very sharp. I have had more people come up to me and comment favorably on the car than than any other car I have ever owned (except my '64 GTO...back in the day!). Mike
