2007 Isuzu Ascender problems

isuzu logo

The Isuzu Ascender is a mid-size SUV built by General Motors for Isuzu. The 7-passenger Ascender was introduced for the 2003 model year as a replacement for the Isuzu Trooper. The 5-passenger Ascender was introduced for the 2004 model year as a replacement for the Isuzu Rodeo and the Isuzu Axiom.

Overview

The Ascender is the only one of GM's GMT360-based mid-size SUVs that was not GM-branded. The Ascender LWB was dropped after the 2006 model year. Reviews warned of a thin dealer network for warranty repairs, and the Kelley Blue Book projected a relatively low resale value similar to the TrailBlazer. However, Isuzu offered a seven-year/75,000-mile powertrain warranty as well as substantial factory incentives.

The Ascender ended production on June 6, 2008, as part of Isuzu's withdrawal from the United States market.

2015-08-14
  • Manufacturer: General Motors LLC
  • Components: EXTERIOR LIGHTING:HEADLIGHTS
  • Summary: General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
  • Consequence: Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
  • Remedy: GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.

Fluid may enter the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.
  • Consequence: A short in the circuit board could lead to a fire, increasing the risk of personal injury. A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.
  • Remedy: GM will notify owners, and dealers will inspect the part number on the door module, and install a new door module if necessary, free of charge. Parts for the remedy are not currently available. An interim letter was mailed to owners in August 2014. A second owner letter will be mailed when parts are available. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-222-1020 (Chevrolet), 1-800-462-8782 (GMC), 1-800-955-9007 (SAAB), and 1-800-255-6727 (Isuzu).

Negative 2007 Isuzu Ascender car reviews

  1. Giovani Hills 2024-04-15

    The vehicle has a strong engine and is great for towing trailers. However, the front passenger seat can be uncomfortable on long trips due to the low and hard armrest, which can cause hands to fall asleep. In comparison, the seats in the Envoy are much more comfortable.

  2. Julien Botsford 2024-02-10

    I think the SUV was a great deal overall. However, the tires on the SUV are not very good. They don't handle well on wet or snowy pavement. If they put better tires on it, the performance rating would be much higher.

Positive 2007 Isuzu Ascender car reviews

  1. Arne Rice 2025-01-09

    You had a great comfortable ride and achieved pretty good fuel economy, even with 6 people and luggage on a trip, getting over 21 mpg. It's great to hear that you're pleased with the value and the 7-year warranty. You also got a great price of $24,250 for this 7-passenger vehicle with all the features. It's wonderful to hear that you enjoy it more than your previous Chrysler minivan, which you never felt safe about due to concerns about the infamous Chrysler quality and transmission. Overall, it sounds like you're very pleased with the Ascender.

  2. Gaston Murray 2024-11-25

    I really like the Isuzu Ascender! It's essentially the same as the Trailblazer and Envoy, but in my opinion, the Ascender has a much better design and comes with a more affordable price and better warranty.

  3. Cleve Hand 2024-11-21

    Good value for the money! I'm glad to hear that you haven't had any problems after two years. It sounds like you're enjoying a smooth car-like ride with plenty of power.

  4. Doyle Cruickshank 2024-11-15

    I used to own a 96 Rodeo and it was great, but my Ascender is even better! It's luxurious and reliable, and I hardly ever need to use the 4 wheel drive because it handles almost anything with ease. The electric driver seat, audio system, and spacious interior make for a comfortable and enjoyable ride. The cargo space is easily accessible and the back lift gate is a breeze to use. The exterior is handsome and low-maintenance. The gas mileage is the same as my Rodeo, and I'm hoping that the Ascender will be just as reliable. Overall, I absolutely love this vehicle and would definitely consider buying another one!

  5. Eriberto Schiller 2024-11-15

    We've only had it for 2 months, so the full story is yet to be told. However, we chose the Ascender because of its superior longevity and performance, just like our previous SUV, the Isuzu Trooper. So far, we're absolutely thrilled with it. Not only was it more reasonably priced than other 7 passenger SUVs we looked at, but it also came with a better warranty.
