2007 Isuzu Ascender Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Isuzu Ascender, grouped by the component NHTSA recorded on the report.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

ALL THE LIGHTS ON BOARD ARE ON...STAYS ON FOR HOURS THAN GOES PARTIAL OFF ... ENGINE LIGHTS ON ZERO GAS ON ALL THE TIME... IS RISK TO DRIVE WITH ALL BOARD LIGHTS ON SO WHAT SHOULD I DO? IN PHOENIX, AZ. WHERE WE LIVE THERE IS NO ISUZU DEALER... *TR

NHTSA ID 10568196 · filed Mar 10, 2014

I PURCHASED A 2007 ISUZU ASCENDER WITH 9,900 MILES ON MONDAY, FEBRUARY 2, 2009. IN NOVEMBER OF 2010, THE GAS GAUGE STARTED TO READ INACCURATELY. IF I FILLED THE TANK, THE GAS GAUGE WOULD SHOW FILLED. AFTER DRIVING APPROXIMATELY 70-80 MILES, THE GAUGE NEEDLE WOULD SLOWLY DROP TO 'E' AND THE LOW FUEL LIGHT WOULD COME ON. I SEARCHED THIS ISSUE ON THE INTERNET AND FOUND SEVERAL SIMILAR COMPLAINTS INVOLVING GMC VEHICLES. I AM NOT AWARE OF ANY RECALLS THAT WERE ISSUED, HOWEVER, I FEEL THERE SHOULD BE. BASED ON THE NUMBER OF PEOPLE WHO EXPERIENCE THIS PROBLEM. FOR NOW, I CONTINUE TO FILL THE TANK, RESET THE TRIPOMETER AND REFILL ONCE I'VE DRIVEN 90-100 MILES, AS I AM NOT PREPARED TO SPEND $800 TO REPLACE THE FAULTY FUEL SENDING UNIT...THE MILEAGE ON THIS VEHICLE IS 24K. THANK YOU *TR

The contact owns a 2007 Isuzu Ascender. The contact stated that while the vehicle was parked and turned off, the driver’s side window unexpectedly rolled down. There were no warning lights illuminated. Upon entering the vehicle, the contact noticed an abnormally strong smoky odor inside the vehicle. After inspecting the vehicle, the contact discovered that the driver’s door master window switch module had melted and was inoperable. The contact ordered a replacement part for the failure. The dealer was contacted. The vehicle was not diagnosed or repaired. The dealer informed the contact that the vehicle could not be repaired because the door master window switch module was an older module. The manufacturer was made aware of the failure. The approximate failure mileage was 94,000.

AFTER NORMAL, MOSTLY RURAL, PERSONAL, NON-COMMERCIAL USE IN CENTRAL TEXAS, THE LF TIRE FAILED AFTER 16 MONTHS AND 27000 MILES OF SERVICE. THE TREAD/BELT SHOWED AN OBVIOUS LARGE BULGE AND SEPARATION FROM THE CARCASS OVER APPROXIMATELY 10% OF THE CIRCUMFERENCE OF THE OUTSIDE TREAD PORTION OF THE TIRE. THIS WAS ACCOMPANIED WITH AUDIBLE EXTERNAL NOISE (AT SLOW SPEEDS) ALONG WITH A FELT BUMP IN THE TIRE AND A SHIMMY ON THE STEERING WHEEL. THE SYMPTOMS WERE REDUCED AT HIGHWAY SPEED. THIS WAS NOTICED AROUND THE LAST WEEK OF OCTOBER, 2009. IT WAS REPORTED TO CONTINENTAL VIA A LOCAL CONTINENTAL TIRE DEALER AND THE ADJUSTMENT WAS 25% OFF OF A NEW REPLACEMENT TIRE. CUSTOMER SERVICE AT CONTINENTAL APPARENTLY DETERMINED THAT 16 MONTHS AND 27000 MILES WAS 3/4 OF THE TIRES LIFE. THREE WEEKS AND 400 MILES LATER, THE LR TIRE EXHIBITED THE SAME SYMPTOMS AND MY EXAMINATION REVEALED AN IDENTICAL BULGE OVER APPROXIMATELY 10% OF THE TIRE CIRCUMFERENCE. AT THE TIME MY FAMILY & I WERE DRIVING TO THE AUSTIN, TX AIRPORT FOR A THANKSGIVING VACATION OUT OF STATE. WHEN I RETURNED EIGHT DAYS LATER, I AGAIN WENT TO THE LOCAL CONTINENTAL DEALER, WHO CONFIRMED MY INSPECTION (THIS TIME WITH STEEL CORDS SHOWING AT THE FAILED SPOT), AND TOLD THEM THAT I NO LONGER TRUSTED THE REMAINING TWO ORIGINAL TIRES AND WOULD LIKE FOR CONTINENTAL TO REPLACE ALL FOUR WITH A DIFFERENT BRAND OF APPROPRIATE TIRES. THAT REQUEST AS WELL AS THE WARRANTY REPLACEMENT OF THE SECOND DEFECTIVE TIRE IS INCOMPLETE AT THIS TIME. CONTINENTAL TIRE CUSTOMER SERVICE HAS ALREADY SAID THAT THEY WILL NOT CONSIDER ANY ADJUSTMENT UNTIL THE TIRE FAILS. IF IT FAILS ON THE HIGHWAY AT HIGHWAY SPEEDS, THE CONSEQUENCES COULD BE DIRE FOR MY FAMILY OR OTHERS. AS CAN BE IMAGINED, I AM NOT SO HAPPY ABOUT THE SITUATION. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
