2005 Pontiac Bonneville consumer reviews

Purchased a 2005 SE used Aug 2013. I thought I got a great deal knowing all the ills the car had. Had all issues addressed before put into service (LIM gaskets, plenum, flush all fluids and a tune-up). We've put 25,000 miles on the car without any problems. For me it rides better and quieter than wife's 2013 CTS bought new for her. Bought a 1992 SSE new 11/91, put 305,000 miles on it. Wife likes it best of all the cars. "Mechanic" at "repair shop" didn't tighten all the nuts causing the engine to fail. Drive train is original. Most dependable car we've ever owned. Expect to get more out of the 2005 Bonneville SE.

i owned a 2003 for 310,000 miles and i hit a deer.... i found a 2005 with low miles and im loving it

Owned my 05 since 07. Had 2 others before this one. Will not drive anything else. Enjoy this car so much I'm looking any distance to find a low mileage one before they are all gone. Car is comfortable & I've had zero problems with it for 7 years.

Possessed? Does the bonne need an excorsism? Having weird electrical experiences? Check the grounding wires, esp. At the grounding boards. They tend to loosen and corrode/oxidize. Bottom line = poor connection. The blower motor ground goes to a block/board under the pass. Side dash behind panels. The guages and such go to ones under the drivers side. As for the crankshaft positioning sensor recurring code, check the engine wiring harness. It may have gotten too hot at one time and burnt a wire.

I've owned four consecutive black Bonnevilles with sunroofs: 1989, 1996, 2002 and now 2005 (last year for Bonnevilles.) My son said the first one looked like a BMW on steroids. The styling on all of them is terrific and totally up to date. I got 31+ mpg on the 2002 during a 5,000 mile round trip (WI to CA) in 2012. When a black ice accident in Dec. 2013 totaled my 2002, in February 2014 I found a 2005 with low mileage in Fox Lake, IL that looks and feels like new. Fabulous maintenance, fantastic engine, great styling & comfort. Deserves the nickname "Black Beauty." - Bill GT6

Purchased at 40,500 miles and love the ride and the power and the cool air conditioning. Just installed a Kenwood in-dash NAV and stereo unit. Looks great.

Can't speak of reliability, just bought a 2005 SE with 71,200 original miles, 1 owner, clean carfax, dealer maintaned. This car is so CLEAN!!! drives like a dream, got it for a song considering it was over 28K new. Wish I had the center console with the shifter in on the floor, but considering how mint this car is I will survive. I am a big man, 6'2", 300lb and I fit well. My son is 6'7" 200lb and he fits good also. I wish they never stoped making them. I feel so lucky to have this one.

I had a 1995 Bonneville which I would have kept until the end but when I heard they were halting production, I hurried and got a left over 2005 in 2006. I absolutely love it - everything about it. I hate that I can't buy a third one! Cool car!

GXP was the fastest car I have ever driven, options were very convenient also, no complaints there. That said, very disappointed by the amount of money I spent to maintain and repair it. Bought it used with only 30k miles on it. The real buying reason was that there was an extended 5yr/60,000 mile GM warrenty with a $100 deductable. Having owned a 2000 Bonny SLE, knew there were gonna be some expensive problems coming such as leaky sunroof (heads-up; there is no official recall on this but the sunroof doesn't always line up with the sealent strip so sometimes it is never actually closed, don't leave it outside in the rain. happened to both my 00' and 05') Became so frustrated with all the repairs (engine mount, faulty brakes, stability system, not to mention each 18" Goodyear EAGLE RS-A tire costs $400) all w/in 10 months of purchase which, of course, were NOT covered by the warrenty. Costs outweighed benefits and was not looking foreward to the next mechanical problem that was gonna set me back another $700-$1,000, traded in before it hit 40k miles. Fuel economy was also dreadful, compared to the V6.

Without doubt the best Pontiac I have ever owned. Can't believe the comfort,ride, handling and most of all over 31 mpg on road trip. No longer made so don't know which brand my next car will be!!!!! Might just keep this one for ever???
