“In january 2012, I received a letter from Mazda inc that the company was extending the warranty on the timing chain to 70,000 miles. In the letter, it stated that a certified Mazda dealer could inspect the vehicle to determine if the timing chain has a problem. On feb 24 the vehicle was inspected by a certified Mazda garage and when my husband went to pick it up, they said it has a slight noise but nothing big.then they asked for all the receipts from the oil changes. …”

“We leased a 2009 Mazda CX-7 (garaged and highway driven only). There was never a problem. The battery died. We changed the battery. Car started and then died. After one month, it again had been flat bedded by Mazda. They did a check and told me they could not find anything wrong with the electrical system, but they found sludge in the engine compartment. They had a recall on a valve which I never received in the mail. The car only had 17,000 miles on it. After 3 years, Mazda came back and said they would cover under lease or extended warranty, which I had. …”

“My wife and I purchased a 2007 Mazda CX-7 from lithia Mazda in fresno, ca. It was a brand new vehicle and within the first 26,000 miles, the air conditioning compressor went out. This was covered under the factory warranty and replaced. Now my the same vehicle has 65,000 miles on it and the compressor went out again. I have been told by the dealership that they will replace the unit (for $1,800) and warranty it for 3 years or 50,000 miles. I fail to comprehend why this is not already covered under the same warranty.”

“I bought this used around june 2010 with approx. 16000 mile. I had oil change at the local garage station. They told me that the oil was very thick. So I had it changed again within three month. It was running fine without any indication and all of a sudden I lost the power and engine quit. I had it towed to garage and they told me that it is better we have it checked by dealer as this has warranty. Mazda dealer looked in to this and told me that the turbo engine is ruined due to gunk in the oil. They asked me for oil change record. I only had since I had it . …”
