“My car leaks fuel under rear if I am fueling. The pump shuts off and I have to do a tiny amount at a time. Can only add 2 to 3 gallons of fuel. Car was on recall list for all 7 recalls and VIN. Check says all have been fixed by previous owner. The same problems are happening again. You should do another recall.”

The second problem is the brakes it's happened to me twice in the last month, both times were driving slow around 5-10mph in the morning when it's cold regardless if I let my car warm up for a few minutes or start up and go.”
NHTSA complaint #10654199, filed 2014-11, 61,295 miles“First off I'm confused by the recall information .I hate having to guess but it's really unclear if the report means that there are no recalls or that they have been fixed aallready.I'm not original owner , I purchased the vehicle and have noticed terrible gasoline smell and leakage..I looked this up and it appears to be an issue the vehicle has had a recall about..I dont know if this has been fixed but I've never had a car with this problem in 30+ years of driving ..and if it has been fixed its obviously leaking again because you can see it on ground and smell it driving it and or parked…”
NHTSA complaint #11291708, filed 2019-12, 170,000 miles“(1) very often I am unable to fill fuel tank beyond 1/2 full. Tried many fuel sites, can occur at all. Has gotten worse in cold weather-below 50*(for so.cal). It acts like a restriction in the fuel neck but none were found. Must be others with same problem.(2) often have to drive with 1/2 tank only.(3) nothing was found, no charges to me. Even if I wait a minute for possible gas 'foam to subside,no help.”
