2018 Chevrolet Equinox

WHEN USING THE BLUETOOTH/HANDSFREE WITH MY PHONE WHILE DRIVING OR STATIONARY, THE RADIO UNIT WITH DIAL OUT A CALL, BUT WHEN THE PERSON ON THE OTHER END PICKS UP THAT PERSON CAN NOT HEAR ME. THE PERSON WILL SAY HELLO SEVERAL TIMES BEFORE HANGING UP. THIS COULD BE AN ISSUE IF I HAD AN ACCIDENT AND COULDN'T GET AHOLD OF SOMEONE TO TALK TO IMMEDIATELY. THE VEHICLE IS OUTSIDE OF THE BUMPER TO BUMPER WARRANTY 3 YEARS/36000 MILES.

CHECK ENGINGE LIGHT KEEPS COMING ON. CODE SAYS DEALER SPECIFIC, WENT TO GO TO DEALER, LIGHT WENT OFF. TWO WEEKS LATER, LIGHT COMES BACK ON FOR A FEW DAYS, GOES BACK OFF. HAD THE DIESEL SYSTEM CLEANED BY DEALER, LIGHT STILL COMES ON AND OFF. CAR HAS 42K MILES, EXPERTLY MAINTAINED. DEALER WANTS $135 TO DIAGNOSE THE PROBLEM THAT THEIR OWN DOCUMENTS SAY THERE IS NO SOLUTION FOR. ON STAR DIAGNOSES FOUND NOTHING WRONG WITH THE VEHICLE AND DIDN'T EVEN SHOW THE 'CHECK ENGINE LIGHT' AS BEING ON. SIMILAR REPORTS FROM OTHERS ONLINE INVOLVING THE 1.6L DIESEL. NO PERFORMANCE ISSUES WITH THE LIGHT ON, BUT CHEVROLET SHOULD BE ABLE TO FIX THE ISSUE - EVEN IF THE CAR IS OUT OF WARRANTY. A TWO YEAR OLD CAR SHOULDN'T BE HAVING RANDOM CHECK ENGINE LIGHT ISSUES.

1. ON 31JAN2018, I PURCHASED A NEW CHEVROLET EQUINOX PREMIER FROM SCENIC CHEVROLET IN WEST UNION, SOUTH CAROLINA. 2. IN MID-FEBRUARY 2018 ON A 5-6 HOUR TRIP, TRAVELING ON INTERSTATE 95. MY WIFE AND I COULD NOT HEAR OURSELVES AND COULD NOT CONVERSE AS THE NOISE WAS OBNOXIOUSLY LOUD, A CONSTANT GROWL. WE BOTH DEVELOPED HEADACHES ABOUT 4 HOURS INTO THE TRIP. 3. THE EQUINOX WAS TAKEN TO VADEN CHEVROLET IN SAVANNAH, GA WITH THE COMPLAINT AND INFORMATION ABOVE. VADEN SERVICE PERSONNEL EXAMINED THE VEHICLE AND 'FOUND NOTHING OUT OF THE ORDINARY'. 4. IN MARCH, 2018, I OBTAINED A DECIBEL(DB) METER, FOR SOUND MEASUREMENT. WITH THIS METER, I WAS ABLE TO MEASURE SOUND EXPOSURE LEVEL(SEL) . 5. SHORTLY THEREAFTER, WHILE ON ANOTHER ROAD TRIP, AGAIN ON INTERSTATE 95, I WAS ABLE TO MEASURE THE NOISE LEVEL. IT FLUCTUATED BETWEEN 81 AND 85 DECIBELS, 'A' SCALE (DBA). NIOSH & OSHA WOULD RECOMMEND LIMITING THE 8 HOUR EXPOSURE TO LESS THAN 85 DBA. AND REQUIRE 6. WITH ANOTHER TRIP TO VADEN, THEY EXAMINED THE EQUINOX AGAIN USING A FREQUENCY METER. MY EQUINOX WAS DRIVEN IN COMPARISON TO ANOTHER ANALOGOUS EQUINOX. VADEN INFORME THEM D ME THEY BOTH SOUNDED THE SAME AND THE FREQUENCY WAS QUITE SIMILAR. I WAS UNABLE TO CONVINCE THAT FREQUENCY HAD NOTHING TO DO WITH AMPLITUDE. I WAS TOLD THAT IS THE WAY GENERAL MOTORS ENGINEERS DESIGNED THE VEHICLE. 7. LATER IN MARCH 2018, I INSULATED THE VEHICLE DOORS, FRONT AND REAR FENDERS, AND BACK HATCH WITH SOUND PROOFING MATERIAL AT MY EXPENSE. THE DECIBEL RATING DECREASED TO 78-82 DECIBELS AT 60MPH ON THE INTERSTATE 95. MY WIFE AND I HAD TO SHOUT AT EACH OTHER TO ENGAGE IN CONVERSATION. 8. FROM THE STANDPOINT OF HEARING CONVERSATION, THIS VEHICLE IS QUITE DISMAL. VADEN CHEVROLET IN CONJUNCTION WITH GMC HAS MADE NO EFFORT TO REMEDY THE SITUATION. PLEASE SEE ATTACHMENT. THANK YOU. RESPECTFULLY, W.L.BOHACH LT.COLONEL USMC(RET)
