“After only having my Rodeo for a few months my ABS went bad but it was replaced by the dealer under warranty. Then shortly after that the warranty ended and gas gauge would read empty but it was full, next I have to add oil to my car every two to three days because it burns oil really bad no leakage or nothing like that. Now I have started adding anti-freeze the same amount of time. There are major tranmission problems with this car and from reading the internet it's not just my car it's Isuzu.”
NHTSA complaint #10272550, filed 2009-06, 105,000 miles“While driving 70 MPH on the interstate, my SUV (1999 Isuzu Rodeo) began make significant noise and lost all engine power immediately. After being towed to local mechanic, I was informed the engine had been blown because of a lack of oil. Documented records show that 5 quarts were replaced 6 weeks ago (2500 miles). The oil has been changed regularly approx every 3000 miles, even though recommendation from the manufacture suggest changing every 7500 miles. …”
NHTSA complaint #10060323, filed 2004-03, 81,000 miles“Coming back from ohio, the oil light briefly went on. There was no indication whatsoever aside from the oil light coming on for a few seconds that a big problem coming up. A few minutes later the engine was making a knocking sound. We try to drive it to a nearest gas station to get it check out. Unfortunately it was sunday and no mechanic was available. We oil change our vehicle every 3-4k miles so we have no reason to believe that it would be an oil problem. We tried to drive it but the engine just died on us. The car only have 66k miles on it and now the car is worthless.”
NHTSA complaint #10098018, filed 2004-10, 66,000 miles“I have had the same problem every year with my air conditioner. The compressor has been replaced every time, twice last year with in 3 months of each other. They have replace the following parts as well gaskets, dryer, valves and cooling clutch. Now I have it in the shop again today. They could not find anything wrong at first except that I was low on freon and they said I should be adding each year. This is not right. Now they tell me they found a bad o ring that goes to the hose off the dryer from the air conditioner. I have to pay $100 for the extended warranty charge. …”
